Interactions With Mystic Obscura
Despite not much being known about her, she cruelly killed Emmalee Forester with the Power Word Kill spell, and seemingly had no issue with killing Lady Eloithe as well. She died at the hands of Ellywick Hollyheart, while dueling Arannis Galandal and Eloithe Mistborn.
