Paths are basically the only thing I have to go on with the rainbows, but I will also consider if the nation has a national pretender 'rainbow', ie a pathcost10 dom1 sort of god. There also might be some flavour reasoning in there, for example the human centric nations might get more of them.

I think restricting PoD to only death heavy nations makes sense, not so much because he's very powerful, but because he's absolutely about death and nothing else. Nations with minor death or cultures that happen to have death gods aren't going to qualify, I think. So MA/LA Ermor, EA/LA Ctis, LA Agartha, Helheim,.. yeah.

The Master Liche, being an archmage in his former life, could go with human nations with solid magic and some interest in death, while the 'jock' version is another death heavy guy. Obviously LA Ermor will get both liches and the PoD, though not the VQ, because vampires want to rule over living cattle not a blasted wasteland of undead. MA Ermor gets PoD, one liche and VQ. So there will be some little changes from age to age that will fit nicely with dom3.

I might also add a national pretender or two to some nations that without the defaults simply have too few. LA Jomon for instance could arguably get Divine Emperor as a choice.

Manticore seems a bit monstrous for Caelum (who are rather angelic) and they get a load of flying pretenders as it is, but it's possible.
