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

By the way, WizardNazyr, you want to rebalance the game so that pairs of creatures have equal strength, so regarding the dark dwarves:
1) a miner and an archer cannot be equally strong; it would be better to make the first level of dwarves mercenaries (the initial version of the first level of dark dwarves) – a javelin thrower with a sword, upgraded to a cloaked figure with the invisibility skill, and the third will be armed like a convict.
2) the mage will be on the skin of a rune priest, with the head of a thane and a warlock's staff.
3) the infantryman will be on the skin of a mountain guard, but with the head of a bonecrusher, a sword, and a shield.
