Related to Judgement, I just got hit in the face by some Fridge Logic. The Time Reaper is from "Ten thousand years hence," But ten thousand years from whose perspective? Aeon is a timeless being, and everyone else is from anywhere from the 1400s to the late 1800s. I know The Reaper probably wasn't being specific, but it bothered me.
As far as we can tell, it was sent back to change the timeline in its boss' favor. This is typically done by going back to a point and doing things that will make things turn out differently. It could easily have come from approximately ten thousand years after the change point.
