GURPS Fantasy: Magic and World

GURPS Fantasy: Magic System and Game World was a supplement for the First Edition GURPS rules, and is unrelated to the current GURPS Fantasy. It had a magic system and an overview of an original medieval fantasy setting. The magic rules would later be revised and expanded to become the default GURPS magic system, which is introduced in the Basic Set and expanded on in GURPS Magic. The setting would eventually be expanded to become GURPS Banestorm.
