|The Eternal Ice|
Envious of Jodah's power Gerda staged a coup with Gustha Ebbasdotter, the royal mage of Kjeldor and her cousin. While Jodah had temporally stored his memories in a reflecting mirror to regain his power, they kidnapped him and turned him over the necromancer Lim-Dûl. Thus, Gerda became the Magus of the Unseen. Hidden under the school was a pit of black mana, forced upon her by Lim-Dûl.
After Jodah's old friend Jaya Ballard freed him, they helped Kjeldor and Balduvia to defeat the hordes of Lim-Dûl in the "Battle of Kjeldor." Jodah then returned to Lat-nam, resumed control over the school, and reprimanded Gerda for her insubordination.
Later, Jodah had to confront Lim-Dûl again and during the fight Jaya transcended to Planeswalkership. After Jaya sealed the pit under Lat-Nam and granted Jodah the ability to live forever they left Lat-Nam for good. From that time on, Gerda legally held the position of Archmage of the Unseen.
