She had stopped thrashing in the grips of darkness.
Ezelreth.
She felt tricked. Deceived. This isn't what she thought he meant by asking for her body in exchange for power.
She was mad at herself for not being specific enough, not asking more questions. Being so compliant and naïve.
But she had been blinded and still is blinded by her desperate need for her daughter. She was being driven by a mother's instinct to protect and preserve.
It was only natural she would be willing to sacrifice the world to protect the people she loved most.
When she made this deal, she didn't realize she'd be a hostage in her own body. She didn't appreciate the fallout of her choices.
