High House Shadow was one of the Houses within the Deck of Dragons. It was associated with the Warrens of Meanas and Kurald Emurlahn. According to Silverfox, it had also once been a Hold. She remarked that it did not share the hierarchical structure of the other Houses; that it was bestial, a wilder place, and apart from the Hounds it had known no ruler for a long, long time prior to being usurped by Shadowthrone. In Tiste Andii legend the interplay of Light and Dark was said to have given birth to Shadow. Oponn had no control in Shadow's Realm.
