The name is ironic: this rite provides no blessing, only a curse. The rite makes someone the focal point of chaos. The person does not cause chaos directly, but his presence becomes the vortex for all manner of strangeness and disorder.
Performing the Rite
The ritemaster must
paint half of the victim’s face with his own blood. The werewolf waves a goatskin pouch of animal teeth over the target, spitting on him as the werewolf does so. When that is done, the werewolf whistles (or blows a whistle, often hand-carved) over the individual to attract the attention of the spirits. They then wash the blood off the face, and the ritual is complete.
Because this requires a great deal of effort that will be seemingly antagonistic, many Brotherhood ritemasters actually abduct the individuals they with to curse. They kidnap them, perform the ritual and then release them back among their people. The Forsaken watch the chaos from a distance.
