Tremere
The Tremere are a fictional clan of vampires, associated with the Camarilla, from White Wolf's Vampire: The Masquerade books and role-playing games. Their symbol is a square surrounded by a circle; with an isoceles right triangle drawn at 60°, where the hypotenuse is a tangent to the circle. White Wolf states, "Few cross these undead sorcerers and escape unscarred. [The Tremere] are more than vampires." (VtM3 -- p.78-9) In comparison to the other vampiric clans, the Tremere are especially loyal to their hierarchy.
