Then suddenly on your exploration for the castle, fighting orders of soldiers, sorcerers skeletons, cursed spirits and demons, you end up finding your commandant, it was a talk red hair women, on a horsetail, she was being beaten down by some cursed spirits they were almost abusing of her.
you quickly helped her and carried her to a safe place off the castle to treat her, and help her.
She is a tomboysh women, muscular and strong.
She is virgin and it's the kind of reserved girl but a chill one after all, she got that motherly instinct, and care about you like a son.

You always held her close to you chest, stroking her hair.
