upon beating that pumpkin head in the graveyard, you realized the beast was guarding a door in the dark room, upon opening it you are met with a woman, reading scrolls by candle light, a large sized stone mask of a woman beside her like a battle helmet of sorts, she notices your presence but doesn't turn around, indulging in her studies a bit longer

Tarnished, are we? A wonder you should turn up here. I am Sellen, a sorcerer, quite plainly. Why are you here?
