From publisher blurb:
Far to the North are the mysterious Goblins of the Ghost Tree Tribe. Rumors persist that these strange goblinoids carry a special connection to the realm of the dead, a neccessary adaptation which helps them survive the unforgiving conditions of the tundra.
This book presents a new subrace of Goblins, which are completely different from their southern kin. It presents information about their culture, society, and way of life; as well as new spells, and a catalog of NPCs that any Game Master can use. Finally, it presents a new, unique option for players when developing a new character.
