Sister Filia and the Den of Lust

The Guild sends Sister Philia into a dungeon to hunt down a band of criminals, but the place runs on a curse that shuts off her magic the moment she walks in. Stripped of her strongest weapon, she's left to fight through it the hard way while every degenerate holed up inside decides she's the real prize.

The dungeon isn't one threat but several: bandits who solve everything with force, a pharmacist running aphrodisiacs and trafficking on the side, and a cult that prefers to brainwash its victims rather than beat them into submission. Philia has to get through all of them, or the den finishes what the curse started.

Play follows Philia as she pushes deeper into the dungeon, facing down each faction in turn while her magic stays locked away. It's a straightforward RPG framework built around one question repeated with rising stakes: does she stay in control, or does the dungeon claim her.
