Mysterious Employer

A mysterious character who hides in the background and employs or somehow directs the heroes, villains or both. Mysterious Employers tend to stay uninvolved themselves, preferring to use money, MacGuffins, or some other way of rewarding their employees for carrying out desirable actions.

Can be a Super-Trope of Big Bad or Big Good, but more often than not the Employer is a neutral party who benefits from pushing the heroes/villains down a particular path.

Very frequently The Chessmaster or, in the event of a group, the Omniscient Council of Vagueness.

Especially common if the heroes/villains in question are Hired Guns.

Compare Anonymous Benefactor and Mysterious Backer.

Note that the identity of the Mysterious Employer is sometimes left secret; his identity itself, as well as his motivations, can be a substantial Reveal... if there is a Reveal at all.

 * In the unfinished Dirk Gently novel, The Salmon of Doubt, Dirk's employer is definitely mysterious. Especially because the book was never finished.

 * Does Our Father Below in The Screwtape Letters count?
 * in Charles Dickens's Great Expectations.

 * Charlie of Charlie's Angels.
 * Similarly, Robin Masters on Magnum, P.I. was a famous but reclusive writer, and later seasons played up the idea that Magnum et al. had never actually seen him. (The first season had Magnum hanging out with Masters in an episode that became Canon Discontinuity.)
 * Wasn't there a running gag that Thomas Magnum came to suspect  was actually Robin Masters (really wrote the books and owned the estate and the Ferrari) because no one had actually seen Robin Masters, with the person heard but not seen being a hired actor? If memory serves,   made a confession of sorts near the series' end to a comatose Magnum in an ICU after a car wreck—so of course said confession could be disavowed later.
 * Higgins confessed outright to Magnum close to the end of the series, in the final few minutes of the last episode Higgins tells Magnum "I lied." with a giant grin on his face.
 * Karla is a little like this in Burn Notice. So is "Management"

 * This is an entire category of characters in Shadowrun, known in the biz as a "Mr. Johnson." They tend to work for a Mega Corp, and act as liaisons between the legitimate face of a company and our less than legal protagonists. One of the major mysteries behind each mission, for those who care to find out, is exactly who they are working for and what their motive is. Given the existence of twenty-first century cosmetics, hackers, counter-hackers, and possibly magic, many players would rather just Get On With It Already.

Video Games

 * In the ultra-violent WII game MadWorld, Protagonist Jack is sponsored by a shadowy figure with a thick eastern European accent who calls himself "13". As the story progresses he reveals bits of information relevant to the ultimate purpose of "DeathWatch".

 * Played with in Metal Gear Solid 2 series, where the initially quite ordinary boss gradually comes to seem more and more mysterious as the plot thickens.
 * Gordon Freeman's sponsor in Half-Life; still no Reveal as to who it is.
 * Also the G-Man, unless, of course, they are the same person.
 * Grand Theft Auto is big on this trope from time to time. The main characters of most of the games will likely run into a pay phone in which an anonymous employer offers assasination jobs to the player's character. Features in Vice City, Grand Theft Auto IV and possibly several others.
 * Grand Theft Auto: San Andreas had C.J. being led around by a mysterious voice on a loudspeaker who reveals himself to be the thought-dead Mike Toreno.

 * StarCraft II: Jim Raynor jumps back into action after being informed by his old friend Tychus that the "Moebius Foundation" is purchasing Xel'Naga artifacts from anyone who can find them for a hefty price.

 * In Sonic Heroes, Team Chaotix is thrust into the adventure by a client sending a radio to them and requesting they do missions for him, promising a huge reward. The voice on the radio is very squeaky and hamstery, but as the story goes along, thanks to all of his strange reactions along with blatant foreshadowing in a mid-story FMV, it becomes fairly obvious that he's long before they actually find him.
 * In The World Ends With You, the Composer directs the Reapers from an unknown location, and only the Conductor ever gets to see him or speak to him. As such, the latter is necessarily tasked with acting as a representative of the former.

 * Until recently, we never saw what he looks like.
