RTF is a global modification that replaces all towns in the game.

Looks pretty good, but the dragon head is already used by the Lizardmen. Maybe something else could be found? From green/crystal dragons or from the same phoenix?
And what mod are these screenshots from?

The heads of the first two are already from the green ones.

In these screenshots, they look decent, and not like a sausage with wings :D
