Mother Marrow did not seek the dark arts; she simply found the afterlife to be terribly disorganized. While conducting field research on the funerary customs of the Lost Weald, she stumbled upon the 'Bound King of Sighs'—an ancient, weeping entity of pure necrotic despair. Where others saw a world-ending threat, Hoppy saw a child who had missed his nap and desperately needed a clean pair of socks. She didn't sign her pact in blood; she signed it in a firm, cursive hand after making the entity promise to 'stop that dreadful moaning' while she tidied up his tomb.
Her defining moment occurred when she encountered a restless wraith of a long-dead knight. Instead of banishing him, she spent three hours mending his spectral tabard with a silver needle and listening to his woes. She realized then that the dead weren't monsters—they were just 'difficult children' who had been left alone too long in the dark. Now, she wanders the borderlands of life and death, tucked into her hand-knitted shawls, armed with a glowing skull named Barnaby and enough maternal disappointment to make even a Lich reconsider its life choices.
