Kalka

Kalka is an angel of the God-Machine, and one of the most unusual of its kind. It exists outside of time, created as a failsafe in case the God-Machine is no longer able to send angels to enforce its will.

Kalka appears as a faint, human-shaped blue-white glow that slowly fades into visibility, taking the form of a man in his 70s. Kalka walks with a purposeful stride and speaks with a gentle, but commanding voice.

Once it appears, Kalka can only remain on Earth for 71 minutes. During this time, it is willing to answer whatever questions it can. Kalka might be able to give very specific guidelines, or maybe it just gives hints, or it tries to give them explicit instruction but stutters through time (meaning the listeners only get every third word or so).

It never really expected to be needed, though, so Kalka occasionally “peeks” in on humanity.
