Azarell

Azarell was a young elven warrior who dwelled in the Dwarven mines of Icewind Dale in the mid–14 century DR, after being separated from her parents. She may have joined the companions in their journey to Menzoberranzan.

History
She could be found by adventurers in the Derro mines and offers to "watch over" the party. Azarell was most unusual, possessing incredible strength, and able to cast spells, as a Fighter. It turns out that Azarell was actually a yochlol in disguise, and may have become aggressive if the party found out.
