So I had an idea for a new breed of vampire, which could either be used as Jade Court (I'll refer to them as such for the rest of this post) or as a completely homebrew court, or possibly a new sort of vampire that has just been created. Anyway, the base concept is thus:
Jade Court Vampires are humans infected with a bizzare, semi-magical virus that alters their fundamental metabolism, accelerating it immeasurably. While this grants them Superhuman Speed, Inhuman Strength, and Mythic Regeneration (as baseline abilities!), their bodies also age at the accelerated rate. Without outside intervention, a Jade Court Vampire created at twenty years of age would die of old age within two years. In order to survive, Jade vampires drain the youth from their victims, reversing the effects of aging on their own bodies while prematurely aging their victims. In order to use this ability, the vampire lays their hands on the victim's heart and forehead, skin-to-skin. The victim usually must be drugged or bound to prevent it struggling, as the process does not paralyze or in any way immobilize the victim. A vampire actively feeding can drain about 1 year of youth every ten seconds. A new Jade vampire is created by introducing the blood of an existing one into the blood of a new victim. The infection, benefitting from the hypermetabolism, usually overwhelms the victim's natural functions within days.
Like their White cousins, Jade vampire's essentially human nature makes them resistant to most of the conventional vampire countermeasures. However, strong Christian faith has proved able to disrupt the disease's hold on its victims, stripping them of their powers and halting the accelerated aging. There have even been rumors that a sufficiently powerful symbol of faith, connected with the free choice of the vampire in question, could kill the disease entirely and cause the vampire to revert to humanity. These rumors remain as yet unconfirmed.
