It is the work of the Weavers to keep the fabric of creation tight, to repair worn spots in the mesh of reality. Skitskurr was a master Weaver, who got tired of this routine. He wanted to create rather than merely maintain. The great guardians saw this as a riot and banished him. Weaver is finally free, but to create a new world, he needs to rip the old one apart at the seams.
