Clanbook: Gangrel, Revised (Vampire: The Masquerade)

As rogues and wanderers, the Gangrel have always placed themselves apart from other Kindred. The Outlanders have no need for the petty Jyhads and useless sniping of the undead - they are vampires, the highest order of beasts! Now, Clan Gangrel prowls the night unfettered by the traditions of the crumbling Camarilla. They have finally called the night their own.

Or Savages Unbound?

As the first entry in an ambitious series of revised clanbooks, Gangrel expands upon the clan's appearance in the revised edition of Vampire:

All-new information accompanies a re-examination of earlier concepts, allowing you to add as much depth to your character as you like. Additionally, the sheer volume of information contained in the new clanbooks (each with 32 more pages than the first-edition books) permits Storytellers to round out their chronicles.
