History
During the Convergence all that was left of Nico's reality was absorbed into the Dark Domain on Primary Earth. Rather than try and flee, Nico decided to stay and fight alongside the others sorcerers who opposed Dormammu's spreading influence. While erecting protective barriers to defend the civilians who became trapped inside the Dark Domain from the Mindless Ones, Nico was approached by a member of the Omega Flight looking for Hela. Nico thanked them for their help against the Mindless Ones, but was unable to help because of how hard the Dark Domain was to navigate.
Nico did however realize that the Wand of Watoomb, which as broken into three pieces, coul be used to guide a path towards Hel. The pieces were recovered by Valkyrie's Omega Flight friend and Doctor Strange provided Nico with a spell to reassemble the Wand. Although Nico herself had doubts, Strange's faith inspired her and she was able to successfully cast a spell that make the Wand whole again. Nico then used the Wand of Watoomb to direct Valkyrie and her friend in the direction of Hel.[1]
