Little is known about Morwen's origin or lifespan, although she has existed long enough to have challenged the Ancient One; a battle which resulted in her being banished from existence, leaving her soul trapped between dimensions.
In the modern age, the battle of Doctor Strange and Dormammu released enough mystic energy to guide Morwen back to the physical plane. At the time of the battle one of Loki's human-born children, a woman named Tess, was nearby, and Morwen, drawn to the godly blood, possessed her. Due to Spider-Man's involvement in the battle which set her free she first set out to grant him a reward--a choice between the world or death.
It was only by the alliance of Spider-Man and Loki that Morwen was banished from Tess' body, although Morwen herself was not destroyed.
Powers and Abilities
Sorcery: Morwen is an extremely powerful user of the mystic arts, powerful enough for her presence to be felt by beings like The Grandmaster, Heimdall, and Mistress Death. Even Loki was unable to best her in direct combat, and would have been defeated if not for the intervention of Spider-Man. Morwen only displayed a few powers but each to devastating effect.
- Enchantment: Morwen has shown the ability to magically enhance objects with ease, as when she transformed several gang members' guns into powerful weapons of destruction.
- Teleportation: Morwen is capable of transporting herself across immense distances with ease, both her physical body and her mind alone.
