Torment

Background
Torment was a member of The Lost Tides. She was captured in Ravenloft by Lord Strahd, but was unbroken, even if she was charmed.

Interactions With Mystic Obscura
Caidove first told Mystic Obscura about Torment, revealing her to have not broken within the confines of Strahd's jail.

Upon defeating Strahd, Eloithe Mistborn lead Mystic Obscura to Torment, rescuing her and promising to take her back. She was seemingly confused but happy to leave.
