Fallout Equestria: Project Horizons/WMG

Project Horizons is a project to develop a colony ship.
All of Goldenblood's secret Projects seem both useful on their own and critical to reaching and adapting to another world. This may have been Goldenblood's version of Gardens -- a way to save ponykind, but by abandoning Equestria rather than healing it.
 * Furthermore, the Core is the Starship Horizons. All the buildings lack windows -- because the need to be airtight. Shadowbolt Tower is the tallest structure because it's the main bridge. The entire core was built in a huge pit so that it can lift out easily but no one can tell it's a rocket once the surface is paved over. After all... Hoofington rises!

The Dealer isn't just a hallucination.
He may have started as one, but now he is a manifestation of the stars cursing Blackjack.
 * Alternatively, he is a ghouled Goldenblood communicating with Blackjack telepathically.
 * Or he's the avatar of EC-1101, projected via Blackjack's EFS.
 * Chapter 39 confirms . I guess it's.
 * Chapter 39 confirms . I guess it's.

Discord is the reason for all of the chaos in Hoofington.
He replaces all the random junk found in lockers, lured ponies to drive everypony into mutually hostile and powerful factions and ensured that any attempt to help or unite Hoofington will fail.* When Rampage mutates in Horizon Labs, she seems to take on a rather Discord-esque appearance - scales, a wing, a horn from the side of her head - perhaps a hint that Rampage, taint, or both, are connected to Discord in some way?

Taint is, wholly or in part, some product of Discord's body.
The chorus in Horizon Labs called Taint "the ichor of the meddler", and only two chapters later, during Blackjack's vision of the stars, she sees "trickster spirits" that "mold and meddle and inspire." Ichor is the greek word for the substance gods use for blood.

Discord needs to be freed to duke it out with the Eater of Souls.
Suppose Flux was used in Folly not merely as a buffer, but as the payload; maybe it hurts the Eater because that's precisely what trickster spirits exist to do. They come into a nice, orderly world where everyone hums the same note, and they introduce freedom and spontaneity.

The blue star that became the Eater of Souls wanted to fill the whole universe with his song, to create eternal monotony. The Eater is therefore a powerful force for order and control. Perhaps its presence is what attracted such a mighty entity of chaos to Equestria in the first place. But the Eater was dormant, so Discord's chaos was too much; it destroyed the order necessary to live happily in Equestria, and he had to be rendered dormant as well. Once the Eater of Souls crosses the Godzilla Threshold, releasing Discord to fight it may become a viable option!

The reason Psycoshy can't access EC-1101 is that
While Sanguine assumed Psycoshy would be able to access EC-1101 due to her. Because of  may have been actively been banned from accessing EC-1101. Sanguine may even know of this ban, however he is unaware that.

Blackjack becomes the Bearer of Generosity
The origional Fallout: Equestria has assigned each other Element, and at this point Blackjack has completely devoted herself to 'doing better' as well as suffering massive injuries. She still cannot stop helping ponys.

Or maybe her virtue is forgiveness. She even. It seems like if Blackjack was the Bearer of Generosity, Little-pip should have been too.
 * This would make sense, given that her biggest hurdle seems to be forgiving herself.

Lacunae will be the alicorn that helps save Littlepip after Maripony.
This one's really just a hunch, I don't have any evidence for it. Although it would help Lacunae to get a little closure.

Octavia's contra bass is a soul jar.
Blackjack got it after she delivered the letter to Octavia's body. She's the only one that can play it, and it's always perfectly in tune. It occasionally moves on its own. And last, but not least, it blocked bullets without a scratch.

Black Jack's real talent is Winning Against the Odds.
Not only in games. In real life. The best bet for her is always risk everything. And, when she finds out? Game Breaker...

Blackjacks MM blood comes not from Twilight, Rarity, or Fluttershy, but from.
Pinkie Pie. Moral has barly been mentioned at all, and considering her ability to ignore horrible, horrible things and her ability to make friends easly, it makes more sence than the other options.
