Subtitle: "The Magical World of Yrth."
From the back of the book:
Beware of the Banestorm
Welcome to the world of Yrth, a wondrous place populated by mysterious monsters and magical races - and by people snatched from our Earth by the cataclysmic Banestorm!
Whole villages were transported - from such diverse locales as medieval England, France, Germany and the Far East. Yrth is a world of cultural conflict, where the Crusades aren't ancient history - they're current events!
Characters can journey from the windswept plains of the Nomad Lands where fierce Nordic warriors seek a valiant death to earn a seat in Valhalla, to Megalos, the ancient empire where mighty magic and political intrigue go hand in hand. Or go south into the Moslem lands of al-Wazif and al-Haz or explore the forbidden city of Geb'al-Din.
GURPS Fantasy provides the GM with a complete world background - history, religion, culture, politics, races and detailed maps - everything he needs to begin a GURPS campaign.
This is an [sic] complete revision and expansion of material that appeared in the first edition of GURPS Fantasy.
