M. Jane McMorbidly
She was the self-entitled family “aGOTHecary.”  She was wife to family Grim-Spin Master Dizzeldee. If there was a deadly ointment, unguent, salve, lotion, poison, gel, balm, curate, compound, emollient, poultice, potion, medicine, agent, prescription, powder, drug, oil, concentrate, distillate, essence, extract, or cream that you required, she could mix it for you and give your enemies what would ail them. She was responsible for the puffer fish poison which Butler Peeves used in his attempted employercide on Squire Drummel. It’s not her fault he didn’t read her instructions first. Her demeanor was said to be "bubbly", although that opinion was probably stated under threat of excrutiating torture.
