The Face of the Master

"'Oh right, you're a mortal. The Grand Court of Third Heaven - Third Heaven being the place you ended up in - is the organization responsible for keeping reality running smoothly! As you can tell, we're a little...understaffed.' - The Face of the Master"

Summary
The Face of the Master is one of the two most powerful entities in the Congregation, alongside AETHER. They reside in Third Heaven, and are one of the few remaining entities which do so. They manifest as a green, glowing, vaguely humanoid figure with glasses, but lacking a face or any other definite facial features. They serve as the Jailor of Third Heaven, ensuring that entities which need to be kept asleep and contained stay contained.

History
The Face of the Master is but a small part of a long-since-fractured entity - one of the original Creators - the rest of which has either been scattered or has faded away. They, alongside AETHER, are responsible for monitoring reality to ensure that it's not falling apart, as well as writing the Reports on the State of Reality.

They formed the "Servants of Reality" to fight BILLY DEMONAYS (when they really could have taken care of it themselves).
