Presumably organized by Margaret, they aided her in taking Allen Calex from his mother and preparing the ceremony to summon Ehrthold. Margaret's cloak eventually caught fire after Ehrthold had abandoned her in the brazier, and the cultists put out her cloak, after which she ordered them to douse the brazier to destroy Ehrthold. Ehrthold strangled the first cultist who tried to do so, but the Man-Thing knocked over the brazier, and Ehrthold vanished. The brazier's fiery coals set the apartment on fire, and Margaret and the rest of the cult apparently perished in the fire.
At least six other cultists existed besides Margaret, two wearing bull masks, one in a goat mask, one in horned owl mask, one in a mandrill mask, and one in some other beast-mask.
