DIASPORA OF THE DEMIURGE
Every dated event in the books, in the order it happened rather than the order it is told. A few times the two of them are describing the same room from opposite sides of it.
Years are Earth-equivalent, as both demiurges keep their logs. Colonists count in Ithaca years, 1.509 to the Earth year on both worlds. Book One's dates come from its timeline appendix; Book Two's from the chapter datelines themselves.
