Gargoyles

The Gargoyles are a vampiric bloodline created by the Tremere as their servitors. Although technically not a Tremere bloodline, the bloodline is largely under their control.
The bloodline was first created via Thaumaturgical ritual in 1167 (or 1121 according to other sources). For the first several centuries after their creation, all their "powers" were in the form of rituals cast upon them by their Tremere masters, and during those early nights, the original gargoyles came into being only in three variants made to fill different roles for their Tremere masters.
The Gargoyle Revolt:
During the mid-15th-century occurred the uprising in which the bulk of the Gargoyle slaves of Clan Tremere liberated themselves from their masters. It must have ended around 1497.

Victorian Age:
At this point in their history, Gargoyles have "evolved" beyond the need for Tremere rituals, instead having developed their own special Discipline, called Visceratika. Escaped Victorian Gargoyles are uncommon. They find the world baffling and dangerous. Their monstrous looks do not allow them to pass through the throng of kine easily, and if recaptured they are inevitably destroyed by their captors.
While travel from Europe to the Americas was not impossible, the logistics of such a task was not easy, and the few Gargoyles who made the crossing found themselves in a world more alien than the one they left behind.
Modern Nights:
In the Final Nights, Gargoyle populations seem to be booming; this is largely because older, free Gargoyles are coming out of hiding to join the Camarilla, because more indentured Gargoyles break free from the clutches of the Tremere, and because the free Gargoyles have also begun to Embrace more mortals on their own.
Gargoyle Variants:
1. The Scouts (Gangrel-Nosferatu): were made to observe the Tremere's enemies and to report any important information to their masters quickly and reliably, and would therefore focus on mastering the art of stealth and Flight. Scouts were also created to advance into enemy territory. They were designed to turn to stone if heavily damaged so that the Tremere or other Scouts could retrieve them later to claim any information they were unable to report back. 
2. The Warriors (Gangrel-Tzimisce) were constructed to serve as front-line soldiers, destroying enemy vampires by focusing on Potence and combat abilities which enabled them to deal more damage to their foes. The Warriors were created for the single purpose of defending House and Clan from its numerous enemies. Inspired by the szlachta of the Tzimisce, they were built to win battles through fear, intimidation, and physical punishment. Whenever a Warrior Gargoyle frenzies, a part of their body turns to stone.
3. The Sentinels (Nosferatu-Tzimisce) were crafted to serve as glorified housekeepers, keeping an eye on their masters' havens and areas of interest and protecting them from harm, which led to them focusing on Fortitude and keeping alert for any intruders. The Sentinels are created as protectors, a sentiment that they extend to their fellow Gargoyles. As the most social of the original variants, Sentinels are a lot more friendlier than most would assume. When alone or without a person they trust, Sentinel Gargoyles find themselves confused.
