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

I had another crazy idea about magic - according to the lore, we have 7 schools, but in the game, there are only 4, and it doesn't seem very good to just take water, earth, fire, and air, but we also have suppression. So, what if we, for example, do this: let chaos magic be fire magic (and put all the fire magic spells there), and chaos suppression becomes water magic, and we put water magic there (using a "level up the skill and get a spell as a bonus" system - similar to the "Rune Shield" skill). That is, opposite schools will exclude each other. In addition, enchantment can be renamed to primordial magic, and teleportation, raising the dead, summoning elementals, magic fist, etc., can be put there (and, accordingly, elemental balance and similar skills) - if the idea is interesting, then it makes sense to develop it further. There is a small issue with the academics - if, for example, it is logical for an elf not to have fire magic and to have water magic, then a mage should have access to everything (and darkness can also be taken away from them, but elemental magic is inherent to them).

that is, such transformations (can also be done differently):
chaos = fire
chaos suppression = earth
summoning = air
summoning suppression = water
enchantment = primordial

considering orcs (they need air and earth), then like this:
chaos = fire
chaos suppression = earth
summoning = air
summoning suppression = water
