Aizel Treemaine

Aizel Treemaine was an elf wizard in Waterdeep in 1479 DR.

History
In 1479 DR, Aizel was hired by the Red Wizard of Thay Varriel to explore on her behalf a necromancer's laboratory inside Undermountain. However, she joined the doomed Rutherford Urmbrusk's party and disappeared.

Just after Rutherford entered a secret passage, Aizel was captured by the vampire Dayan, who used her for one of his experiments. She was placed inside a helmed horror guardian. To power it, a person had to die inside the armor and Dayan chose Aizel as a sacrifice. She was slowly dying from starvation and only Dayan could free her from the armor without killing her.
