The Gargoyles are a bloodline created by the Tremere as servitors. Although technically not a Tremere bloodline, the bloodline is largely under their control.
The Gargoyles were created via Thaumaturgy using the blood of three different clans: the Gangrel, the Nosferatu, and the Tzimisce. The blood was combined to form three specific types of Gargoyle: scouts (Gangrel-Nosferatu), warriors (Gangrel-Tzimisce), and sentinels (Nosferatu-Tzimisce). Warriors focus on Potence and combat Abilities; sentinels focus on Fortitude, Alertness and other such Traits; and scouts practise Stealth, Survival and the like.
