He wanted to leave Ledgerdomain to destroy his enemies, so Charmcaster told him her name was Hope, that names have power, and wrote Ledgerdomain's secret true name on Michael's hand so he could return at any time. Unlike Gwen, Charmcaster's magic has a lightning-like effect and a whiter coloration, while Gwen's is more solid and darker, also instead of creating balls of pure mana for projectiles attack, Charmcaster creates lightning bolts. In addition to that, she wore black fingerless gloves. Charmcaster was finally defeated after Gwen summoned a mystical vortex which sucked her and her rock monsters away. When they reach Zs'Skayr, he gives the Rune back willingly since he has already drained it of much of its power. She loses in the third round when she flies across a lava pit only to crashland on a floating rock when a lava bubble bursts dangerously close to her.
While she still had godlike power over the realm,  she had stopped visibly wearing the Alpha Rune.
Because the accident that mutated Kevin never happened, the Kevin of this timeline was weaker, and Ben's Team was unable to defeat Charmcaster and her uncle. When this happened, an alternate timeline was created: one where Hex and Charmcaster ended up ruling the Earth. Charmcaster screamed, took back the mana which he fed on, and forcibly evicted him from Ledgerdomain.
