2735 are remnants of a pre-human civilization, which is thematically similar to 1000 and appears to be aligned with the cyclical history thing you're hinting at here.
Ah, I see! I'm actually expunging something different in there. 2735 isn't representative of the, er, type of cycles I'm referring to there — it's just a civilization that predates 1000. That's the same thematic cycle, but that sentence means something else…
(There's more stuff I have to write about 1000 eventually, which will eventually be linked there and might clear up more, or outright tell the reader.)
EDIT: Made some tweaks that might clarify.
