Shiver Invakus

Shiver is the head of the Invakus Family. She is said to be able to summon entities from the dark realm that have, they say, driven her over the boarder of sanity and into the lands of wild impulses, convulsions of thought and a myriad of lunacies. However, this very unpredictability often wrong foots her rivals and has become seen as a strength by those in the family that grow in wealth and power under her leadership.
