[WtA]
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.
