Personality: Quiet, dark, calm, and highly intelligent. She's not someone to be messed with or taken lightly. Even though she doesn't care about others, she can be incredibly loyal. If that loyalty is formed. She is extremely slow to trust, and has a cold and cunning attitude.

These two necklaces cannot be lost or touched by others.

Powers: Manipulating shadows, along with being able to control and talk to reptiles, real and mythical. She can transmit messages into the minds of others, and knows forbidden spells that use blood magic. At times she seems like a part of the shadows herself. She can also transform into different types of dragons and summon her weapons.  Making direct eye contact with her will send the other person into a state of slight hypnosis where their mind gets hazy, like with a cobra. When this ability is activated, her eyes don't reflect light. She can absorb magic from crystals, though it temporarily changes the color of her eyes.

Backstory: Mostly unknown, she works as an assassin, a mercenary, a hired killer, a ninja... She can do many things, and eventually created a name for herself as the most efficient mercenary out there, a ruthless and cold individual. However, she showed no interest in the job after it was completed and she was paid. When Thor and Valkerie captured Loki, she was hired to interrogate him. From there she was somehow dragged into joining their team, despite her protests.
