God

Takes the appearance of a young girl, bright and innocent. Claims to be the Creator of the entire universe. And she says that things will be getting bad, very soon.

God's recommendation
Notable, in God's first appearance, is her recommendation on what to do about the fact that death is impossible in the City of Sin during Plot Arc 2. In explaining it, she likened the out-of-balance multiverse to a scale with a weight on either side. Killing Noah, and eliminating the power of Yellow Springs, took away a weight on one side. Thus, she said, killing Nimrod, and eliminating the power of Babylon, the City of Life, would restore the balance and return the multiverse to functioning capacity.

Needless to say, many were skeptical of the solution that involved destroying life in order to fix death.
