Sister Thera is Father Morvin's wife. They were advisers and healers for the Dwarvish nobles of Knalga. They could not save them from Khazg Black-Tusk's troops, but they survived the Orcs and Trolls only to be captured when Malifor's skeletons appeared. Malifor wanted to study them to see if there was a way to counteract their arcane attacks. Tallin freed them, so they join him. Sister Thera then heals Elenia. Sister Thera is often overacting, in a very unclerical way. She also often uses coarse language, unladylike. Sister Thera and Father Morvin will mary Tallin and Eryssa.
