How 'bout the burden of time. Not much point againt R'lyeh, since they've taken some Atlantians as slaves, but your troops have an old age of 500, and thanks to R'lyeh in era's past, you don't have anyone left alive from that generation.

So, if you get that up, you won't see the effects for hundreds of turns, and Abyssia... Well, let's just say that if they aren't waging war already, they will be soon. You probably could make a temporary alliance between you and Ermor though. They'll benefit from Utterdark much more than you, but you'll see some benefits too, and the Burden of Time isn't much of one.

What kind of results have you seen the cold climate have on ice weapons and armor?

I've seen my Snow Warriors get a +2, though I haven't experimented enough to see the full range.
