This spell was originally created by the Kuni family and is still primarily practiced by them, although knowledge of its prayers has spread to other Clans. It is an elaborate ritual spell, requiring an hour to cast, that calls on the powers of Earth to purge the land of the Shadowlands Taint, driving out all the evil kansen in the area. The spell will remove the Taint from the land, plant life, and inanimate objects within the area of effect. It will not remove Taint from living creatures, nor will it affect powerful Tainted artifacts or objects made of obsidian.
The removal of the Taint, however, is not without a price. The elemental kami in the area of effect are also weakened and purged by the spell, especially the Earth spirits whose efforts are called upon to power it. In the aftermath of casting this spell, the local spirits are scattered and weakened, inflicting a +15 TN penalty on all Spell Casting rolls within the area. This negative effect will sometimes fade with time, especially if it was cast in a single location surrounded by normal lands. But if the spell is cast over a wide area, such as the Kuni Wastes, the elemental kami will usually permanently leave the area, reducing it to a gray, lifeless wasteland.
