Gerda Äagesdotter

Over 2000 years into the Ice Age that fell over Dominaria, Gerda Äagesdotter was second in command to archmage Jodah at the Kjeldoran School of the Unseen at Lat-Nam.

History
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 to the necromancer Lim-Dûl. Thus, Gerda became the Magus of the Unseen. Hidden under the school was a Bottomless Pit, 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 became a Planeswalker. 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.
