The Void Queen

The Void Queen is an evil doppelgänger of Gabrielle Grimm. There is a tentative truce between the two. Grimm doesn't mess with the Void Queen's holdings, and the Void Queen won't invade our reality. The Void Queen is just waiting for signs of weakness to break the truce.

In her native dimension, the Void Queen has ensorcelled and enslaved most of the heroes who stood against her. Now, they serve at her leisure. There is still a beleaguered Resistance trying to overthrow her. After that world's Chief Jack Carpenter was freed from the Void Queen's control and a spell was used to disguise his free will, he's been secretly helping and aiding the Resistance while fooling the Void Queen into think he's loyal.

The Resistance is beginning to gain some momentum and is becoming a thorn in the Void Queen's side.
