Back when their lair was young Balthazar and Erynnis took in a wandering refugee who professed to know the secrets of directing the dead. Though her magic and abilities were repugnant to other lairs, the couple saw no real evil in her and tentatively allowed her to stay. Since then, Sorsha has become a fiercely loyal member of their lair and a dangerous force against their enemies. While not a true necromancer she is able to manipulate the bones of the dead into active puppets that enforce her will.

The bones she wears as adornment are all that remains of her charge, another old and venerable guardian who simply passed away from old age while teaching Sorsha her magic. Kilmer is the only one who knows this, however.
