"'I am Us, the oracle of the Gods. The Gods did indeed send me. They wished to speak with you!' -Us' first words."

Us
Us is the oracle, the representative of the gods (i.e. the readers). He lives and is created in the Alpha Timeline. He is capable of relaying of the gods' words, and being controlled and acting as the agent of the gods. He is shown to be pious and a believer of the gods' benevolence (which is questionable at worst).

He's a good friend of Worker. He takes his oracle position somewhat seriously, as seen by his reaction to losing the Cube of Secrets, which was an emotional seppuku."'That is precisely why I quit. I can't protect them. Besides, what does it matter anyhow. The Gods are gone after all.'"
