I think adjusting PD for a nation is possible. Heat 1 would be more thematic than neutral temperature preference.

As for Zamzummites, I'd say punt the cost up a lot rather than have them cap-only. If they cost 300+, that'd be enough of a barrier to stop there being too many of them (until the late end of the game, when it's less of an issue I think). Rephaite sages are adequate battle mages for many purposes. Making the Talmai expensive summons would mean Adon became the thugs of choice most of the time, I guess. Until the sci-fi era of the late game, I guess you'd be forced to keep the few summoned Talmai you could afford back home forging. I sort of like the third misc. slot on the Talmai, as it feels thematic.
