Umbral Tether (Rank 1)Edit
The Umbra is a shifting world where logic does not always apply, and losing one's way in it is an easy affair. Theurges have worked around this by using this Gift, which creates a silvery "umbilical cord" connecting the Garou to their point of entry into the Umbra. Only the Theurge who creates the tether can see it, though some spirits have a tendency to trip over it, which can sever or alter the cord. This Gift is taught by a spider-spirit.
No roll is needed to create the thread, however after each hour spent in the Umbra, a single point of Gnosis must be expended to maintain it. If this point is not spent, the line slowly corrodes from the point of entry and toward the Garou.
