Following the practice of "smudging," this rite is designed to keep a space clean of unwanted spirits.
The Garou burns a bundle of specially gathered herbs (taken with great thanks; only taking the shoots and not the parents)--these herbs could be Sage, Sweetgrass, or other similar herbs. By smudging the area once a day every day for a month, the Garou is able to repel non-Gaian spirits from the area. (Note: It does not lock them out, but makes the area distasteful to be around.)
NOTE: This Rite is currently proprietary to Heather, though it's possible someone else could have developed the same rite. Please talk to Luna before taking this rite.
