Althaea

Althaea was a young Half-Elf Wizard who was transformed into a Star Spawn Larva Mage.

History
Born to an Elven Princess and a kindly human mage, Althaea was an upbeat young wizard who lived a happy life in the city of Haelrion until 853, when she was captured by Nhagruul and his Priests of Vecna. Taken to Margoth and tortured, Althaea was eventually exposed to a swarm of odd worms from the Far Realm, that the disciples had learned of from the Book of Vile Darkness. The worms devoured her flesh and transformed her into a larva mage, an alien creature that was nothing more than a writhing mass of worms in a vaguely humanoid shape. Driven mad by her new form, Althaea was placed into suspended animation and left to rot in one of the temple's prison cells. When she awoke, centuries later, Althaea discovered that the temple had fallen into disrepair (as most of the priests had slaughtered each other) and, in her attempt to escape, that the cell was guarded by a magical ward. Forming a plan to escape, Althaea used her Hat of Disguise in order to resemble her original form, that of a young Half-Elf mage and lay in wait for adventurers exploring the ruins.
