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

In Heroes of Might and Magic, there were 2 "Zloboglaz" bosses: the Red Eye of Madness, which resided in an abandoned dwarven fortress, and the Eye of Terror, whose location I don't remember. However, the first "Zloboglaz" was very memorable because I accidentally found this fortress, barely cleared it, killed the boss, and didn't get any useful loot because this dungeon was intended for the individual quest of the Rune Priest – it was a fantastic disappointment and utter suffering.
