MARDEK/WMG

See also The Great Mardek Theory Thread, located on the game's home site.

Pseudolonewolf reads TV Tropes.
Seriously, the guy has referred to, like, twenty tropes BY NAME. Now, Lampshading's common, but this... This guy has to be a troper.

"He is."

The Shocking Story-Dividing Event
Pseudolonewolf has said before that there will be a major event that separates chapters 1-4 and 5-8. Any guesses on what that might be may go here.

Gaspar is going to destroy Belfan in chapter 4.
The Fig Hunter Encyclopedia refers to Belfan in the past tense, implying that something happened to it. And Qualna says that Gaspar's approach is "Go in and burn everything". Presumably he'll burn Belfan to the ground looking for Rohoph, or perhaps he'll destroy an elemental crystal? There is a huge volcano in southern Belfan (the one you go through to find the fire temple). A minor NPC in chapter 3 mentions that if it erupted, it could wipe out all life on the planet. Gaspar is a pyromancer. Chekhov's Gun much?

Rohoph is going to be separated from Mardek at some point.
Rohoph seems to be controlling Mardek more and more, and also seems to be a bit evil. Deugan probably isn't going to like this, and he probably remembers that Rohoph let a clue slip about removing his soul from Mardek without killing him. Deugan will probably find out and try to do that.

Mardek will die during the chapter 4 climax.
A corollary to the above. It seems like the only way to separate Mardek and Rohoph is to kill them, so perhaps that will be the major storybreaking event. (The game's name wouldn't make sense after that, though, which makes this unlikely)

Rohoph or Enki's ship will be repaired, and Mardek and friends will fly to Anshar.
That's it. No dramatic Earthshattering Kaboom or whatever. The only difference is a change of scenery.

Something will happen to the Aether Crystal.
If taken or destroyed, whether Gaspar intends to or not, all life on Belfran will become weakened and there will no longer be any birth. The threat of gradual planet-wide extinction will force the characters to stop Gaspar/leave the planet to save it somehow.

Gaspar burns Goznor to the ground.
This makes Goznor a Doomed Hometown and give Mardek a personal reason for seeking out Gaspar, not just for destroying his home but for outright killing everybody who lives there before they have a chance to escape. Mardek will be Darker and Edgier and becomes a Villain Protagonist with Rohoph's influence.

Chapters 5-8 will be a different genre.
This is from the Kongregate forums: basically, the items have gotten so overpowered that it seems unlikely there could be any semblance of balance by the eighth chapter, unless the items we currently have are somehow revoked... or rendered irrelevant.

Steele...

 * ...will reveal one hell of a Freudian Excuse before doing one or more of the below items, possibly one that makes the "coming from a *girl*" line make sense and probably at about the same time as he starts showing more emotional range than "lust/aggression". "They tried, YALORT have mercy, but every time they looked at me, I could tell that they saw that bastard."
 * ...will learn how to use the Dark Crystal. One Apocalypse Wow coming up!
 * ...will be taught how to use the Dark Crystal. Gaspar, anyone?
 * ...will join forces with Emela after she goes mad with isolation, despair, and a bit of guilt. "I was going to punish her for what she did to me, but she's been hurt worse than anything I could ever manage. Nice job breaking her, Deugan!"
 * ...will somehow upstage the Governance di Magi.
 * None of these seem plausible based on the fact that Pseudolonewolf really hates the whole "Oh, they're not horrible, irredeemable monsters because they're actually bad and have a lack of empathy, it's just because they're *insecure* deep down or had a bad upbringing" type of thing. Steele executing a Heel Face Turn or having a Freudian Excuse is extremely unlikely, especially since he appears to be coming close to crossing the Moral Event Horizon. (Plus, the fact that he has unique battle music shows that, if he does turn good, he it will be in a later chapter than 4, since I doubt Pseudolonewolf composed a special boss theme to use all of two times or so)
 * Who said anything about a Heel Face Turn? The closest thing I mentioned was Emela pulling a Love Makes You Crazy Face Heel Turn. And only one of these requires that Steele not be rotten to the core just because that's the way he is.

Chapters Five through Seven or Eight will focus on an entirely different set of heroes.
Think Golden Sun. Whether or not Mardek and company show up would be debatable, Mardek likely would since the series is named after him. The guess states "Seven or Eight" since it's possible that both groups of heroes unite for a final battle in the last chapter.

Melchior will be really, really tough and insidiuous.
The GdM, despite their occasional silliness, have shown themselves to be rather effective villains. Thus, whenever Melchior is finally called in, he/she will be revealed to be an expert in Obfuscating Insanity.
 * That or his silliness extends to extreme unpredictability in strategies, thus making him that much more dangerous.
 * More evidence for this: assuming that the pattern of GdM member per chapter continues, Melchior will be one of the last ones you fight, implying that, despite looking stupid and insane, he is extremely powerful.

The Governance de Magi members will all be Flunky Bosses.
So far, both of the ones we've fought have been. Gaspar might be more straightforward, but it's entirely possible that Pseudolonewolf will continue the pattern.

Rohoph will be the final or semifinal boss.
Judging from chapter 3's ending, Rohoph is Jumping Off the Slippery Slope and sprinting towards becoming a Knight Templar hard and fast. I suspect that Mardek's friends aren't going to like this, and Rohoph and Mardek are going to be separated somehow. When they get to the Violet Crystal, Rohoph will execute a Face Heel Turn and/or go crazy. I'm thinking that he'll probably be like Gruen in Raider, where you fight him before the actual final boss, and his battle music would probably be a remix of Rohoph's Theme or something.

Moric's inspiration for becoming a necromancer -- and the reason for his fractured mind -- was the death of a loved one.
Right before he dies in chapter 2, he mentions the name of an annunaki we haven't heard anything about yet. It's possible that this was his mate, who died years before the game began. Their death could have deeply traumatized Moric, and he became a reclusive, borderline insane necromancer because of it.

Qualna's traits that were amplified by the Violet Crystal were his pacifism and submissivism.
When were are first introduced to Qualna to his first two appearances in chapter 1 and 2, one could have easily believed that the Violet Crystal made him an Insufferable Genius and a Smug Snake. Indeed, when possessing King Gonoroth, he can't even keep in character, dropping insults about the human race (much like Rohoph does).

Later, however, we see that it was all in act, that Qualna was merely acting like a smug bastard in order to make the Governance think he was on their side. He tries to get Rohoph to come back with him and gets distressed when Rohoph intends to kill him. Accepting his possible fate, he barely puts up a resistance and hopes that Rohoph will be kind enough to allow him passage to the afterlife. After Rohoph seals him away and we get a dreamstone, we find out that he not only knew that the Violet Crystal were affecting his and the GdM's minds but it had greatly affected Rohoph too. Not only that, but he, like Rohoph, also wanted to destroy the Violet Crystal before it was too late. However, fearing he would be chased off like Rohoph, he put up his prideful act, using the persona of Clavis as a mouthpiece for his true views and we see him act more like his true self both after the death of the king and in the Astral Tunnel. Qualna has alwasy been a diplomatic person and preferring to use words instead of weapons; the Violet Crystal amplified these characteristics, which is why he turned out nicer than the rest of the GdM, Rohoph included.

Melchior will be the last Gd M sent to kill Rohoph.
Melchior tends to be pretty popular and for good reason; he has the best lines. As such, Anu will send Belthazar, possibly because Anu might see him as the most competent member and, when he fails, will have no choice but to send Melchior last. That means Anu will be stuck with Melchior. Alone. With no one else to talk to. He'll have to deal with Melchior and his Cloudcuckoolander ways. Hilarity Ensues

Anu is really the Big Good.
Anu realized that the galaxy was stagnating under the rule of the Gd M. In order to ensure that those important to him/his next incarnation would see a better future, he summoned the Violet Crystal and caused Rohoph to rebel. Sending the Gd M off to die at Rohoph's hands is actually a Thanatos Gambit/ Suicide By Cop attempt.

...will be back.
Soul sealing, especially just for vengeance, is NEVER a good idea. Toward the end of the eighth game, Mardek will realize that Rohoph is the villain and his dying action will be, as a "Screw you" to Rohoph, to release the Gd M so that they join with his friends (and Anu kicks out Steele) and fight him.

Rohoph will commit a Dark genocide on Anshar due to the effects of the Violet Crystal on his mind.
Rohoph is obsessed with "goodness", light, and order. He once mentioned during a party reaction that he will "Bring light to Anshar". In the Dark Temple, he states how not only does he hate all Dark Temples, but Dark itself and thinks that everyone only needs Light. While we have yet to see one, apparently there does exist Dark people of the Good alignments, plus Dark is needed to make people unsatisfied enough to want to improve themselves and/or society, but Rohoph can't see that. As such, he'll probably either destroy the Dark crystal of Anshar and/or start a plan to kill everyone of his kind that is of the Dark element, even if they are Chaotically/Neutrally/Lawfully-Good; killing a Always Chaotic Evil person is one thing but a Good person just because of their element? Sounds like the plan of someone who's mind is warped, the kind of thing that the Violet Crystal does.

The creature inside the Violet Crystal is a necroparasite.
Raider and MARDEK are set in the same universe -- the same galaxy, even -- and the creature inside the Crystal looks suspiciously similar to a necroparasite. In Raider, they're shown to have some possession and mind-controlling abilities, which would fit with what's happening to the GdM. We also never saw the ending of Raider; it's possible that, after defeating the Parasite Queen, a single necroparasite escapes into the void of space, or the Parasite Queen is so powerful that the only way to stop it is to imprison it inside the Violet Crystal. It then falls to Anshar in a meteorite, and the rest is history...

The Violet Crystal is the fig crystal of the entire universe, and only one fig crystal is needed for all sentient thought in the universe.
The libraries talk about the ether crystal, but not about a fig-elemental one. Apparently, YALORT didn't create one when forming Belfan, and therefore, it does not seem like it is a necessary component for life. However, what if there is one very powerful fig crystal that is the source of all minds and thought in the entire universe? (Or just the galaxy, if you prefer) It was probably lodged in a meteorite somewhere, and came to Anshar when the meteor fell. The mind-warping stone in the lost monastery may be similar. (A shard, perhaps?) Alternatively...

Each planet does have its own fig crystal, but instead of being formed at the planet's creation, it falls from the heavens at a later date.
So far we have seen two objects that could possibly fit the description of a fig crystal. Both have fallen to planets in meteorites, and again, the libraries make no mention of creation deities making fig crystals when forming planets. Perhaps it falls when the planet is "ready", and helps advance it technologically? (i.e., starts it going technologically when it's been stuck at a Class IV or V state for a while, since those classes have little to no technology) The lost monastery's stone is probably a mistake -- again, possibly a shard. Belfan might not have been ready for it yet, so the minds weren't fully capable of adjusting to its power, and they broke instead. (However, since elemental crystals are nigh-indestructible, if a shard managed to break off, it implies that something very bad could have happened to Belfan's fig crystal)

The Violet Crystal planned Rohoph's rebellion.
Qualna reveals that Rohoph was also altered by the Violet Crystal in Chapter 3, and he has clearly decided to Jump Off the Slippery Slope and is practically the Token Evil Teammate by the end of Chapter 3. He is probably the weakest of the GdM on his own, and the VC and/or the creature inside it could easily pick him off after having Rohoph kill all of the others.

Rohoph did not jump off the slope due to the Violet Crystal's influence.
Or at least, not solely due to it. In Chapters 1 and 2, Rohoph was rather insulting, but showed no indications of being a genuinely evil person; only in Chapter 3 did his change truly become evident. Now, what happened between the end of Chapter 2 and the beginning of Chapter 3? The same thing that happened to the Volcano Shaman-- he sealed someone's soul away. What was enough to drive the shaman to madness would surely be enough to drive Rohoph to it as well, especially considering the fact that he had done so to someone he had thought was once his friend, only to find out that Moric despised him. This could have easily shattered his mind-- or at least severely harmed it-- over the course of three years.

YALORT is real.
...And Pseudolonewolf is his prophet, attempting to spread the word of YALORT subliminally via his flash game series.
 * Alternatively, Pseudo is YALORT. There's a Mind Screw for ya.
 * This actually makes a surprising amount of sense, since, technically, Pseudo is the creator of the Astrosles Galaxy and all the beings within.

YALORT will be an optional boss.
The fact that there's a Divine element implies that we'll be fighting a god at some point, and a fight against YALORT would be really amazing. Plus, the bonus bosses are pretty epic as it is -- the only way to top that would be to fight the creator of the entire galaxy.
 * One problem with this theory: A member of your party is a paladin of YALORT whose entire skillset is basically calling on YALORT's power. Maybe the ridiculously named Cyrian god would fit, though.

Something terrible is going to happen to YALORT, or to the Yalortian religion.
In Pseudolonewolf's platforming-slash-dating sim game "Clarence's Big Chance," the date asks about religion, to which you can answer that you are a Yalortian. If she answers positively to this, she mentions that there aren't many Yalortians left after something called "the Dreaded Incident." Now, maybe this is a one-off gag, but it's entirely possible Pseudo was foreshadowing future events in one of his other games...

Chapter 4 will not have a Time Skip.
Chapter 2's was lampshaded and weakly justified, chapter 3's was fully justified. However, if chapter 4 has a Time Skip, things will get a little ridiculous, since Gaspar is not one to screw around and will probably proceed with his "burn everything to the ground" plan immediately. It would also reduce the sense of urgency if he is indeed going to destroy Belfan.

Mardek will meet up with Enki in chapter 4.
If Belfan is going to be destroyed, Mardek will have to meet up with his father before then. Plus, his dreamstone seems to hint that he knows about the annunaki, and apparently doesn't like them, which causes a lot of potential drama if he finds out Rohoph is possessing Mardek. Also, Lilanea's line "I am a patient woman, but I cannot wait much longer" strikes me as Foreshadowing.

In chapter 4, you'll fight the World's Saviours for the final time, and they will end up dying in an Alas, Poor Villain moment.
Perhaps they will try to fight you for an actual reason, or Bartholio finally gets his hands on a crystal, but turns insane or something because of it. You'll end up killing them in the end. Also, if chapter 4 does wrap up business on Belfan, that'll probably have to happen, unless the WS manage to become stowaways on the ship to Anshar or whatever.

There will be around 30 party members total.
Consider the number of slots available on the save crystal's party screen. Prepare for lots of level grinding.
 * There's currently 27 party slots when storing items, but 33 party slots when switching party members.

Individual guesses (feel free to add/edit)
Deugan (rejoining):
 * Reasons for:
 * One of the major characters
 * Can buy another sword of his weapon line in Aeropolis
 * Though, the sword in question is just a generic weapon that turns out to be used by Bartholio, the other Greatsword user.
 * Dialogue with Mardek at the end of Chapter Three
 * Reasons against:
 * May want to continue on his own path, not wanting to hold Mardek back
 * Additional notes:
 * May or may not keep his Lone Wolf persona

Emela (rejoining):
 * Reasons for:
 * Clearly wants to rejoin Mardek
 * Dialogue in Water Temple suggests she will in Chapter Four
 * Reasons against:
 * Required to stay in the temple due to Guardian duty, unless a way can be found around that

Enki:
 * Reasons for:
 * Established warrior/adventurer, established weapon- a katana
 * Dreamstone suggests he's still out there, and wants to meet his son again
 * If the action really does leave Belfan, odds are he would come along too, not being native to the planet
 * Serve as a mentor/guide on otherworldly adventures
 * Reasons against:
 * As the probable captain of the Ninevehn ship, he's likely to have issues with Rohoph for whatever the latter did on Nineveh.

Jacques:
 * Reasons for:
 * As a Guard captain, has the skills and training to be a party member
 * Knows and trusts Mardek, loyal to same cause
 * Revealed weapon- a rapier
 * Reasons against:

Saul:
 * Reasons for:
 * Obligatory Dark team member or Token Evil Teammate
 * Sudden disappearance in Chapter Three suggests future return
 * Popularity as a character
 * Could theoretically use scythes, a weapon programmed into the game
 * Might join in return for being given the necromantic tome
 * Reasons against:
 * As a villain, would have few reasons to join the heroes, except possibly an Enemy Mine

Muriance:
 * Reasons for:
 * Seems headed for an inevitable conflict between his desires and the desires of what's likely Zaephros, if his Dreamstone is any indication- would look for help from anyone he could, i.e. Mardek and company
 * If he can suppress his desire for crystals, might not be entirely bad
 * Unique weapon, in the form of guns, two of which have appeared but are unobtainable in the games
 * Reasons against:
 * Currently predisposed against our heroes, if he takes the path of the Chaosbringer he would likely fight against them instead
 * Word of the omniscient Encyclopedia says he is Chaotic Evil
 * Is a recurring villain

The World's Saviours:
 * Reasons for:
 * Unique weapons have shown up for Bernard and Vinnie that aren't obtainable otherwise. Bartholio and Aalia have been briefly playable with their own stats and skillsets
 * Technically are heroic, if Bartholio, who is Lawful Good, ever figures out the truth, he would likely feel like helping Mardek
 * Bernard seems to have some sort of backstory, possibly involving the Dark hero mentioned in Goznor's magic shop, and appears to be misguiding the Saviours so Mardek can progress without as much impediment- and, of course, would be a rare Dark team member
 * Reasons against:
 * Aalia's speech manner would be annoying to read for the entire game.
 * Recurring villains
 * Except for Bernard, they just seem to be silly comic relief villains with no real purpose other than to be a parody of generic RPG heroes.
 * Additional notes:
 * Not all four may necessarily join, if any. Bartholio and Bernard seem to be the most likely candidates, however.

A Trilobite:
 * Reasons for:
 * Belfan's third and most notable remaining sentient and sapient species (besides humans and reptoids), would help to represent Belfan if the action heads to other planets
 * Species already established as having strong warriors with various skills and magic
 * A Water party member that isn't entirely magic or support based
 * Rule of Cool
 * Reasons against:
 * No real indication of them holding much influence on the future storyline at the moment

A Wraith
 * Reasons for:
 * There's a bookcase that mentions rumors of a hidden village of sentient Wraiths guarding the Aether Crystal.
 * Obvious potential for a plot involving the Aether Crystal being taken and being pursued by a Wraith.
 * An Aether-element party member!
 * ...RuleOfCool?
 * Reasons against:
 * No real indication of Wraiths actually existing... Yet.

Jered, as the Amiable Dingo
 * Reasons for:
 * Blatant Comic Relief and/or Joke Character who appears as an Expy of Social Fox and Deugan, in case Deugan doesn't actually rejoin.
 * Another character from Goznor, could fill in The Generic Guy archetype.
 * In Chapter 3, he says he wants to become an adventurer. Possibly hero worships Mardek after the events of the third game.
 * Mauve Shirt that is easy pickings for being killed off to show that things are getting serious, without killing off someone important.
 * Reasons against:
 * Since when have NPCs with non-unique sprites ever been taken seriously?

Some chick with a Dark Affinity
 * Reasons for:
 * Because there's a bookcase quite early in the game explaining the elemental affinities and how, among other things, they affect people in Day-to-Day live and relationships. The point that Light and Dark can never get together is stressed quite a bit. Mardek's a Light type and he's not been very succesfully romantically so far, especially because of Rohoph, so...
 * Reasons against:
 * Rohoph, for one.

The Stone from the Lost Monastery changes the alignment of mortal souls to the Fig element.
From the Fig Hunter wiki: "People of the Fig element are exceptionally rare. They have unusual mental skills such as psychic powers, though their minds can often be on a level 'beyond genius', such that they work on a completely different wavelength to others and seem 'insane'." Why would this be the case? Well, we know that Fig is the element of the mind, and that the Dreamrealm, a.k.a. the "Figrealm", is the home of thoughts and dreams. It may be theorized that people of the Fig element are more in tune with the Dreamrealm; this can range from merely being somewhat out of touch with reality for people who are just slightly more Fig than any other element, to being completely cut off from real world stimuli for people that are almost entirely Fig-elemental.

If the above is true, then we can go on to argue that the Monastery Stone (which many people believe is a whole or partial Fig Crystal) increases the concentration of the Fig element in mortals exposed to it, eventually shifting their elemental affinity to Fig. Over time, they go from being mildly spaced out to completely insane as the concentration of Fig continues to grow.

We know that Bostolm was exposed to the stone. Consider that he constantly raves about Pixies, and that they are very common within the Dreamrealm, a Fig-elemental parallel dimension, it may be the case that his mind is almost completely inside the Dreamrealm, where he constantly encounters Pixies (as your party does while walking through the Dreamrealm), and is almost always under the influence of Addle Gas. His one moment of lucidity may have been during a time in between Pixie encounters.

Enki is the captain of the scientists in Xantusia.
Listen to "Fallen From The Stars", the background music for the spaceship. It quotes "Enki's Theme". Also remember what Lykel says about their captain -- "He always liked that swords and sorcery stuff. When we crashed, he grabbed a sword and started helping people." This would also explain why Enki refused to talk about his past to Lilanea, since obviously he wouldn't want to say "I'm from a different planet! :D" We will probably find out when/if Mardek meets up with him in later chapters. Notably, if he is, then he might be able to repair Rohoph's spaceship (or his own, for that matter), which would give the party means to travel to Anshar.
 * The final dreamstone pretty much confirms this, despite not directly mentioning Enki or the scientists. A character who is very clearly Mardek's father is searching for something which is very clearly the missing ship part. It also hints that his home world was conquered by the Annunaki, or some other manipulative one-eyed aliens.
 * Also, Mardek mentions feeling that the crashed spaceship feels familiar and one of the crashed scientists mentions how he resembles their captain.

The soul gems will be used for something.
It's been theorized that the creature within the Violet Crystal will use them to free itself. It's also possible that they're necessary to unlock an optional dungeon, a la the Miasmal Chalices.

Muriance is the reincarnation of Xaephros, and will get the dark crystal for himself.
Who is Xaephros? Well, in one of the dreamstones, a scene about Solaar's past is shown. There, a prophet has a vision, and he claims that a villain will try to get his hands on the dark crystal, and this would bring death and destruction. He says that this villain could be the reincarnation of Xaephros, the Chaosbringer, who probably was one Solaar's kind and sought the crystals for himself. Solaar is sent to Belfan (the villain would appear at Belfan) to prevent this from happening. This, on its own, would hint that Steele would be Xaephros. But, there is a dreamstone that contains Muriance's thoughts. He thinks about the crystals, and how he needs to get his hands on them, even though he doesn't understand why. And, interestingly enough, he has seen dreams of greatness in which he is a dog. If you draw a line from the dots that there dreamstones form, you can see the full picture. Muriance is the actual reincarnation of Xaephros, and he feels that he should get the crystals, and sees dreams about being powerful, and a dog. But, these are probably either memories about his past life, or just reflections of his past nature. Anyway, it is quite clear that he indeed is the reincarnation. And, the prophet of Solaar's thoughts said that he would get the dark crystal. So, I'd say that the Mardek and friends go and defeat Steele, but the crystal ends up on Muriance, this fulfilling the prophesy. I don't know what happens then, though. Maybe he will gain a massive power-up and manage to escape Belfan's (theorized) destruction? Maybe he'll use Rohoph's escape pod and Mardek and others will use the larger spaceship?
 * Alternatively, the fact that Muriance is the reincarnation of Xaephros is just a cosmic coincidence, and the actual evil from the vision is (choose one: Steele, Rohoph)

Bostolm has Obfuscating Insanity.
If you level Legion up to level 30, Bostolm will suddenly become lucid for a moment, before Baron von Doomkill tells him to shut up and start blathering about pixies again. He hastily complies. The high priest of the lost monastery also says that Bostolm was one of their wisest members, so perhaps he did resist the effects of the purple stone, but doesn't want to show it for some reason? Perhaps we will find out more in later chapters. Or, perhaps he's normally wise and lucid, but just has an irrational fear of pixies that causes him to freak out whenever they're mentioned or he thinks they're around. (Which is apparently all the time...)

The final boss' element will be Divine.
A non-elemental enemy would be pretty tough to take down, since they would have no weaknesses, and you wouldn't be able to resist their attacks either. It would be fitting for a Final Boss.

The Dragon will be a semifinal boss.
The Violet Crystal seems to have powers over the mind, so when Mardek and company try to attack it, it will probably use their own fears and imaginations against them by trapping them in Mental Worlds. Mardek's will probably be the dragon's lair, where he has to face off against The Dragon for real.

All the chapters will end with Downer Endings, including the final one.
So far, the chapters we've seen have ended on progressively worse notes, and it could be said that chapter 3 had an outright Downer Ending. This could be setting the stage for what's to come; everything is going to end badly. Maybe Pseudolonewolf will subvert our expectations by ending the series with a good ending, though. Who knows?

Alternatively, the trend of downer endings will reverse as part of the Shocking Story-Dividing Event, especially if it involves Rohoph.

Not only is Mardek's father not from Belfan...
...he's also a member of whatever equivalent of the royal family his world has. The fact that he's likely the captain of that extraterrestrial ship already implies he's fairly important, but also look at his last name: El-Regis. "Regis" is Latin for "king." Pseudolonewolf's a pretty smart guy, if all of the shoutouts, trope references, meaningful names, and bilingual and such are any indicator. It's not too far-fetched that he would know the word. Also, he's used the term for one other character's surname: Donovan's, and we all know whose son he is...

There will be a crossover with Raider.
Pseudolonewolf is supposed to be working on the third version of Raider some time after finishing the third chapter. Now that the third chapter's out, he'll presumably start it soon enough. And, since both games are set in the same universe, what better way to get that across but have Arkus end up joining the party (or something)?

Bernard is the guardian of the Dark Crystal.
He mentions at one point that he prefers that one to the others (although he is dark element, so...). He's also said to be limiting his power, so who knows how strong he really is, very possibly strong enough to be a boss of his own.
 * He's already arguably the most powerful of the Saviours as it is. Pulling a I Am Not Left-Handed would be right in character.

Bernard the old man is Bernard Stormkiller.
They share the same name! All coincidences are true! Also explains why he gives off hints of him being a Retired Badass who's using a Power Limiter.

(Bernard Stormkiller is the Dark-elemental hero mentioned in the leftmost bookcase in the Goznor magic shop.)

Rohoph is holding back on the full extent of his power.
It's taken Rohoph 8 years to regain the ability to heal, cleanse status effects and buff allies? He, the Annunaki with the greatest prowess in Light magic? Something isn't right, especially since Moric's soul transfer, if anything, made him more powerful within the day. Yes, there is the problem of using Mardek's body to do so with Mardek still in it, but he's had an awful long time to figure this out.

Mardek will ascend to godhood at the series' end
The series' title is officially written in all caps, the same way as names of deities in-universe. Also, the mythological Marduk rose to power after defeating the leader of Anunnaki.
 * One kink with this theory: Pseudolonewolf has said before that the only reason the game name is capitalized is to differentiate it from the main character. He could be lying, though, who knows.

Miasmal theory is incorrect.
Essentially, monsters being mindless creatures born of miasma to wreak havoc frees people (such as Emela or Mereador) from guilt over killing them, as opposed to the human enemies. However, a couple of things make this seem odd. For one, it's noted that creatures can be partially miasmal, such as pixies; also, at least one kind of monster (Gruuls) can be domesticated. Finally, creatures such as undead and golems add to Miasmal Chalices, despite being formed of something other than miasma.

This could be Gameplay and Story Segregation, or just Fridge Logic, but consider what game we're talking about. More likely, it's setting everyone up for a one-two punch of What Measure Is a Mook?-- even those which were assumed "okay" to kill will be revealed as more intelligent and/or innocent than previously thought. From the evidence in play, Miasma is more likely something akin to blood or life force than the entirety of a random encounter's existence.

Rohoph can only bring out Mardek's natural magical talent.
Similar to the Rohoph is holding back his full power WMG, only in this case, it's unwillingly. Mardek was born of the light element, and his father is a famous adventurer  that presumably knows a thing or two about magic. Mardek's personality is perfect for a healer, too--he's mostly a Sure Why Not type of guy, which is fitting for his passive skills. So in the years, Rohoph has been unlocking Mardek's true potential through his guidance, not through his own power. Rohoph is therefore either incapable or extremely limited in his ability to use his own magic which Mardek could never learn.

Only Belfan has an Aether Crystal.
It's mentioned a few times by Rohoph that Belfan has something weird with its gravity, and the Aether Crystal is theorised to be/to be at the planet's core. It's possible that, due to Aether and Fig being opposites, with the Violet Crystal likely being the Fig Crystal, the Aether Crystal attempts to draw those affected by the Fig Crystal towards itself in order to destroy/purify them, which is why Rohoph came crashing down so suddenly... And possibly why he's suddenly showing signs of further derangement, as the Aether Crystal could very well be attempting to pull his soul apart. Or something it could do.
