Wow, did I just say that?
Tharma is one of the Ancestral Witches who destroyed Domino and Daphne. She is one of Valtor's mothers and the Ancestral Witch who looks the most like Stormy, one of the three descendants of the three Ancestresses and has power to manipulate the weather and storms like Stormy.
When Tharma still had a body, she looked like a hunch-backed old woman with pale skin, fizzy grayish-white hair, and a long, thin hooked nose. She wore a black dress, a black cape, and a black mask. With her mask on, she appeared to have glowing yellow eyes and it is unknown if this was her real eye color or an effect of the mask.
In her spirit form at Cloud Tower, her dress, cape, and mask had a purplish dark red color while her skin had a pale ghostly gray color and her hair was purple, in a similar style to her descendant Stormy's.
