Wim can bend others into tools for her purposes and only an Avatar and a Yaluthu can bring her back into a semblance of sanity.

Wimsah was in a coma before the rising of Resicor, and her mind was wide open when the planet’s consciousness burst out. Her already wild talent grew to absurd proportions and a coma was the only safe place for her.
Benliar, Avatar of Roden, was asked if he would take on responsibility for Wimsah and her open mind. With her power, only the mind of a world could contain it, and he volunteered.
Spot has known that Wimsah needed him since she first landed on his world. He has watched her mental landscape, and she is in definite need of fuzz therapy. He is just the fuzz to oblige.
