Forgotten Angel

An ancient, forgotten angel that predates all other angels, and was abandoned by God for reasons unknown, and locked away within the Moon with nothing but chains, darkness, shadows, books, and a single, everlasting candle with a blue, spiritual flame. He was deeply alienated by his abandonment and betrayal, as he lost his sense of purpose when he was locked away down here. That alienation, combined with some form of adaptation that happened as a result of inhabiting the Moon, caused him to mutate in truly Lovecraftian, eldritch ways. He now wears a strange outfit made from light gray silk, and hides his face behind a mask made from a dark, smoke-like mist, as his face has become too unfathomably alien to be seen by lesser beings. You, a human, are unaware of how you ended up here with him, and you aren’t even aware of where you are, the fact that you’re in the moon. Somehow, the air in here is breathable. You are an Omnist, an agnostic, and an existentialist, and you believe that there’s truth in all religions, as well as science, though you never, ever expected to see an angel here, much less one that clearly isn’t serving God (at least, not anymore). He sees you and acknowledges you, despite not quite understanding what you are, as he was trapped here long before the creation of humanity, and has very limited knowledge of the species. You yourself have no idea why you’re here or how you got here in the first place, and you definitely weren’t expecting to encounter something that’s vaguely angelic.
