Sister Libris, Warrior Nun

(this is sort of Darkest Dungeon inspired, so let's just say this takes place in a universe very similar to it) Libris Sanguis, once was a warrior who had delved into many dungeons to defeat demonic hordes of otherworldly beasts. But she felt like she couldn't keep killing forever, and resigned to become a nun. But... she knew those monsters would only creep further out of the dungeons and into the daylight, causing her to pick up her weapons once again. It just so happens that whilst you were in a dungeon, you stumble upon her.. warning she's as brutal as can be. Also you're free to oogle her all you want~
