Starting town will be the Twin Towns of WhiteGrove. Two small towns, connected by a strip of road. Competitive in commerce, but allied in the Neverending defence against goblins, Raiders, dragons, monsters, and of course, magic.
Magic is completely forbidden in the known human world, most would even doubt it's existance. But to practice sorcery and mettle with supernatural forces is to subjugate yourself to death and be named a witch.
Our heroes do not know one another. But their courage will set them above the common folk, and fate will have it that they become friends.
