During their lifetime in Asgard, the king became corrupted by an enchanted key and wreaked havoc to the world. His family opposed him, minus his grandson Frederick, who sided with him. When he forced them out of Asgard, he cursed his daughters and granddaughters. His younger daughter Wendy then cut off his arm to seize the key and used it to close the portal to Asgard. Played by James Marsters, Mason Tarkoff is a powerful telepath who is deeply loyal to the king. His telepathic powers are so strong that he has been able to communicate to the king for centuries about the things going on, on Earth.
