The first one has a reference to 2e Chronomancy.
Without complaining too hard, it'd be way easier to ignore ALL temporal stuff, until a full "time"-timeline is done. Then add in any Chrono-stuff as like a Marvel Cosmic continuity problem. And of course c.o. says pun-pun here as code word for t.o. time tricks.
I call it Deep Time.
Le'Shays , Atropus , Pandorym , Erebus , Far Realms , maybe Old Ones , figure in.
But say with Deities & Demigawds, each "canon" pantheon has it's own deep time era and myths.
I've no real idea where to draw the line.
