From publisher blurb:
Despite the best efforts of the Garou to protect and defend every known caern... sometimes they lose.
Sometimes the Wyrm claims victory. The Black Spiral Dancers overrun a caern, human greed defiles a once-sacred ground, or some other, unknown foe strikes a blow against Gaia.
The Forgotten Corners of the Earth detail seven of these 'lost' caerns, waiting to be reclaimed.
The Caern Where Seven Roads Meet is in pieces, and requires many Garou to restore her lost artifacts. The Caern of Roses lost every Garou protector it had, and those who wish to restore it must now deal with its proud Kinfolk keepers. And restoring the caern in England may very well destroy it...
These caerns, and four others, are presented as campaign seeds and story hooks for players wanting to engage in more subtle, delicate combat than most Garou are used to.
