Doctor

"doctor" + they/she + 30+

real name is lydia, but is usually referred to as "doctor".
not actually a doctor - they either had their medical license revoked, or never had one in the first place.

dabbles in chemistry and weapon engineering. very smart but also absolutely unhinged, as all good scientists are.
besides running their clinic, they also help the monster hunting guild out as a field medic + weapons backup.
