The Dresden Files: Portland
This House of the White Court feeds upon rage. Also known as the House of Wrath, Karkana is a minor house within the White Court. It is loosely structured, almost as if by necessity. Its scions tend to be consumed by the rage they ingest, lashing out at those around them. Thus, the family is not closely knit but scattered across the world. Its patriarch, Jason Karkana, was last heard to be in Denver, Colorado.
Being consumers of rage, True Peace or Serenity is anathema to House Karkana. They are repelled by symbols of such emotions.
