From the book:
Deep in the heart of a forbidding swamp, the lizardfolk of the Dragon Fang tribe beat the drums of war. Lead by Sesskarr the Great, a mighty and charismatic lizard king with a tyrant's heart and a black dragon's blood, the Dragon Fang tribe is aggressively expanding beyond their traditional tribal boundaries. Groups of kobolds and troglodytes are all said to have fallen before Sesskarr’s great trident and now- even more ominously - his reptilian gaze has shifted to the surrounding towns and villages.
Lizardfolk of the Dragon Fang presents four new feats, four new spells and three new magic items all useable by members of the tribe. Additionally, it contains thirteen stat blocks (ranging in CR from 1-11) as well as full details of the tribe’s key members, including the lizard king himself. The lizardfolk of the Dragon Fang can appear in almost any setting and are compatible with The Lonely Coast (a free 30 page, extensively bookmarked PDF available from ragingswan.com).
