The Iravotum is a dangerous forest located deep underground within the Palace of the Blue Djinn. In this layer, unwanted desires are able to come true and numerous creatures lurk within the forest to prevent tresspassers from coming in. One of the creatures, the Optabellower, eats all wishes. Also in the Iravotum is King Nebuchadnezzar II. This king has been there for millennia, and it survives only because he, literally, has nothing to be desired. The Rukhkh, a flying mythical creature, also lies within. Through his travels to rescue Philippa, John had to deal with all of these as well as an illusion of his father, Edward Gaunt.
