Young yet stoic member of the hunters, Lady Maria is a corpse believed to be a failed experiment, a suffering patient, a victim of mania, and ultimately succumbed to death and darkness. She ended her own life in the Astral Clocktower, where the nightmare then took her to guard the hamlet she once violated. As a student of Gehrman, she is also believed to be the killer of the child of Kos and took its umbilical cord. Maria deeply regrets her murderous actions.
