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

By the way, who should be the basis for the Cabiri? They should breathe fire. The dwarven dragon is more similar to them, but it's too big.

They don't necessarily have to breathe fire; they could also throw something, so I think Orcish Warriors would be suitable. I just saw Magogs made from them in NCF, and the idea stuck in my head.
