Gwen, Ben, and Kevin follow Aggregor into a mystical inter-dimension full magic and mana called Legerdomain with the help of Charmcaster, who was born there. They believe Aggregor’s target to be the Alpha Rune worn by Addwaitya, ruler of Legerdomain, which they suspect is a disguised piece of the Map of Infinity. Gwen and Charmcaster work together several times, and the two develop a bond that seems to lead to Charmcaster changing her ways. While the group tries to steal the Alpha Rune, Aggregor uses the distraction to knock Addwaitya out and take it himself. Gwen, Ben, and Kevin escape Legerdomain with Charmcaster’s help, but Charmcaster stays behind to free Legerdomain and her people from Addwaitya’s rule. Ben promises Gwen that they will find a way to return and help Charmcaster after Aggregor is defeated.
