This book updates the original Yrth of GURPS Third Edition, Fantasy and Fantasy Adventures. It's a complete world background - history, religion, culture, politics, races, and a detailed, full-color map - everything needed to start a GURPS campaign. Phil Masters (Discworld and Hellboy RPGs) and Jonathan Woodward (Hellboy and GURPS Ogre) have added new peoples, places, and plots, as well as lots more on magic and mysticism. And it's all consistent with the just-released GURPS Fantasy and GURPS Magic.
So prepare to make your own mark on Yrth. Plunder elven ruins while evading the desert natives. Play a peasant-born hero . . . an orcish pirate . . . a Muslim double agent commanded to infiltrate the Hospitallers.
