Only the members of the secretive Ivory Priesthood learn this rite. To perform the rite, the priest must first spend a day ritually purifying herself of all sins, according to the Priesthood's creed, and any negative thoughts. She must also spend a few hours meditating on the idea of her own death and her attitude towards it. A priest who is not reconciled to her own mortality can find the Dark Umbra a disturbing and unsettling place. Once the purification is complete, the Garou faces a Death's Breath spirit in the early twilight of that evening. She must let it breathe into her mouth, which sends a chill like a rod of solid ice through her body. She may then step sideways into the Dark Umbra. She may remain there until dawn the following morning.
The player spends a point of Gnosis and rolls Willpower (difficulty 7). If the roll fails, the rite ends and the character is plunged into a terrible Harano-like depression that costs her two dice from every dice pool for the next 24 hours. If it succeeds, the character may make a normal stepping sideways roll to enter the Dark Umbra, as described above. Once in the Dark Umbra, the priest appears as a dark patch in the normal Penumbra. If she fails to return to the material world by dawn the next morning, she is trapped in the Dark Umbra unless another Ivory Priest or a kindly Silent Strider helps her back across into the material world.
