Rite of Shrouded Glen[]
This rite causes an area within the Umbra to become invisible, so that it cannot be seen from any other area of the Umbra. There must always be at least five participants in this ritual, and a ritual fast lasting at least three days is required to purify the participating Garou. The Uktena, who are particularly adept at this rite, maintain that all participants must come to the rite with their bodies clad only in painted symbols representing earth, air, water, fire, and (for the ritemaster) the spirit world.
System[]
The difficulty of this roll is the caern's Gauntlet + 4. Any participating Garou can contribute Gnosis to this rite. Ten Gnosis points must be spent to make the effect permanent. Otherwise, the number of successes achieved equals the number of hours the Umbral Glen remains hidden. If the area the Garou attempt to hid is larger than the caern itself, the amount of Gnosis required increases by two for each one-mile radius the participants attempt to enshroud.
