Julii

The nobles among the Kindred of Rome, and founders of the Camarilla, the Julii claim descent from Remus.
They may be the ancestors of the Ventrue, or they may simply be a now vanished clan who filled the same niche in Kindred society. The Gangrel clanbook implies that the Ventrue and Gangrel are descended from a common ancestor, possibly the Julii (although the Gangrel would have to have split from their forebears sooner, as they were present in Rome during the days of the Camarilla).
Like the Ventrue, the Julii are masters of Dominate, the Kindred Discipline of mental subjugation.
