LRB Vampyre Sect

Rules for running a gang of vampires. Well not real vampires in the WFB sense, instead, a particular Immaterium creature attaches iteself to a human host and in return for offering inhuman abilities it forces a thirst upon him for human psychic energy which the host drains through drinking fresh human blood. As the creature is norished with the energy it grows in power giving the host further abilities until eventually the creature spawns a new creature which can then attach itself to another human host.
