Edimmu

An Endimmu is a vampire body possessed by seven vicious spirits, which feed on the souls of diablerists.

The first Endimmu was deployed by a coven of Babylonian blood-sorceresses against En Isiratuu when it became clear he had somehow transcended the usual negative side-effects of diablerie. The En was persuaded to try to diablerize the Endimmu, and when he did so the spirits ripped him apart and devoured him body and soul. However, the coven had called up something they could not put down again: upon devouring the En, the Endimmu released seven skeins of seven spirits, each of which took possession of another nearby vampire and transformed it into another Endimmu.

This might not have been a problem if ritual diablerie had not been a common feature of Kindred society in Babylon. The sudden plague of Endimmu instead threatened the very existence of Kindred in the city. To exorcise an Endimmu requires knowledge of the bans of all seven of the spirits within it, which are never the same from one case to another. Once an Endimmu is immobilized by its bans, an exorcism can be attempted. While a partial exorcism involving only some of the bans is possible, if the Endimmu devours another diablerist before the exorcism is complete, the missing spirits will regenerate in addition to the seven new Endimmu created.

Endimmu in their "natural" form are warped creatures with distorted physical forms due to the many spirits inside them. Their empty eye sockets glow blue, and somewhere on their body an "Endimmu brand" is visible. However, they are able to pass as a normal vampire, concealing everything except for the brand. Their powers use Essence rather than vitae.
