Tephra

Tephra is a human wizard.

History
She trained herself from an early age and, seeking more power, applied to join the Starfire Academy in Silverstone. When she was rejected, she journeyed to Brightstone to look for adventures that could get her the power she so desired. Joining with Naraya, Ro, Gryff, and Harthur, she investigated the disappearance of a powerful wizard over seven hundred years ago, eventually coming into the possession of a tome covered with faces that constantly stretched and moaned.

Tephra was transported to Estorium along with the rest of her party, and was eventually tasked with finding and stopping a mind flayer who was attempting to open a gateway to the Far Realm. They delved deep into the old temple of Boccob within the ancient city of Derenath, located the gateway, and slew the mind flayer. However, instead of closing the gateway, Tephra opened it fully, claiming the power within and allowing the nightmarish hordes of the Far Realm access to the world. She was last seen surrounded by aberrations, attempting to control them as her former party members fled.
