Thea

Thea was a human girl who appeared when The Hydra's Head tried to have Theseus 'brought back' following their death.

Early Life
When the guild freed Barovia from the Devil Strahd they called in a favour from a priest they had met on their travels and attempted to resurrect their friend, Theseus. This did not work as expected and instead they found returned to them a young, blond woman with severe amnesia who they named Thea in memory of Theseus. With no where else to go, the guild brought the girl onboard.

Life in the Hydra's Head
Garrick took Thea under his wing to teach her magic, which she seemed intrigued to learn.
