Destiny of the Endless (Psychopomp)

From Jenny Everywhere Wiki

One universe version of Destiny was one of the Endless — in fact, he was the oldest of the seven Endless, predating even Death. He held a Book which was in fact a part of his own being, and recorded every event that would ever take place in the Endless's dominion (which was suggested to include not a single universe but an entire multiversal cluster branching out of it, including all extant alternate histories of this universe). After the passage of time led to all sentient beings slowly dying out, and with them, the other Endless, Destiny became the second-to-last Endless and was finally taken by his sister Death, who was left as the last sentient being in the dead universe.
