Vampire the Masquerade from a Real Power Gamer
For those that do not know, there is a set of games that deal strictly with all the horror mythology. One of the games is called Vampire: The Masquerade. In the game you role-play a vampire. Your enemies are humans, werewolves, mages, fairies, ghosts, oh and other vampires. In the game your powers are called disciplines. The vampire characters are divided up into families of vampires, sort of like the mafia, called clans. Because a vampire is made by infusing a human with blood, that new vampire takes on the genetic imprint from the blood of the vampire that made him. Voila! You have your clans.
