On Earth during the Cretaceous period, an Elemental, Urgence Evergreen, attempted to stop a green Catalyst Comet (the Lich) from hitting Earth, but the other Elementals, Chatsberry, Balthus, and Slimy D were opposed. The Ice Crown is created in an attempt to stop the comet from hitting earth, and as a result of Gunther's usage, causes its victims to become like his master Evergreen; or rather, how he saw Evergreen as: someone who is constantly firing ice magic and ordering people around.
