Timeline Remnants were fascinating things, but they were also immense tragedies. They were created by copying oneself out of a straight, forward-moving timeline. From a moment of temporal stagnation, one pulled out oneself from a billionth of a second ago, ultimately becoming two selves: one original body and one Timeline Remnant. It was an exceptionally sophisticated method of duplication. Genes, cells, soul, memories, thoughts—everything was identical, because the Timeline Remnant was oneself from a trillionth of a second earlier.
