Cavall (The Hollow King) was a peer who knew the science would be changing soon by looking at the world in a new world. He created a mediation CD as part of this and an associated camp which drew in a lot of the young and revenue. He used synthesiser in his works. He told Ian Gilmore that he knew that he was tricking him. He didn't believe the truth that Cook was creating the cult. He crashed his helicopter to kill the mushroom creature.
