A side-note for the lizard-debate: the new theme Desert Sun is available to all nations, including C'tis. It spreads heat even beyond your Dominion, meaning that map will warm up like Atlanta in July. Those poor Caelum are left just standing around with their armor and weaponry dripping all over the furniture.
Well, unles they counter with the Heart of Winter dominion, which has the effect of spreading cold instead of heat . . .
