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

Will the magic schools remain new, or will you revert to the old ones?

I think I was going to revert to the old ones, but I don't remember anymore.

I was planning to bring back the old ones and even came up with a way to redistribute them among the castles, but I didn't do it. Now that demonology is going to be scrapped, I will definitely bring back the old magic schools.
