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

my old idea – 4 lich heroes representing 4 schools of magic. I specifically chose not the strongest abilities for the heroes with "urban" magic because I never played as Dyraell or Faiza (and also not as Ravenna, her chaos magic didn't fit, Naadir with his darkness-summoning and ghosts was a priority), but specialists in logistics/teleportation and fireballs have always been popular, regardless of the schools of magic.
