Because they have a Cold Preference of 3 in the game. They never mentioned anything about it if they intended it. And it's 70 Free points, unless you want -15% Income from all provinces except your home, then you can get 120 Points.
Ooops, seems lika an error introduced by the modding part. They will become cold 3 in the next patch, so don't get to attached too the heat loving caelum.

The Armor is still the same So if you want to be a Dominions 2 badass, play Caelum with Heat 3. Also make sure you have Production 3, because what would be the fun in playing Hot Caelum if you cheated and didn't use their fun, fun troops?
Heh
Why not make Hot Caelum a theme?
Over time some of the fliers got more accustomed to heat (living in a volcanic territory or something) and now they really dig it.
