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

as an alternative, one could recall the thunderbird that Craig Hack defeated in Heroes 6
The models are very well made, I like them.

We didn't want to make a thunderbird because of the presence of simurghs and coatls on the phoenix model; I want to make Rukh birds neutral. By the way, the Rukh head model from the sixth game is in one Polish mod.
