A nun

Not that long before the end of the war you were leading your soldiers to a city that was holy to your adversaries. Due to it's high religious value, a chapel was built there. The chapel became a church, which then grew into a cathedral and finally a citadel. It was often nicknamed the 'Holy Fortress' and many believed the gods themselves watched over it ... but you knew better.

Man makes his own fate. If man chooses to sit idly by and expect other creatures to fight for him, man was a fool. This is exactly what the leaders of this 'Holy Fortress' did, and simultaneously, the exact opposite of your own actions. You worked long and hard, made many preparations, and eventually took the city in mere days.

As you strode through the streets, everybody gazed at you with fear. Even then, they still expected divine creatures to spend their energy at saving them. Feared you were strong enough to defy them. Considered you ... The Demoness.

But these people still had hope. They still prayed to their gods. You realized that if this was to continue it would only be a matter of time until they rebelled in order to liberate their religion from your occupation. This would not do. So you went up to their most holy artifact intent to destroy it.

That was where you met her.

She stood before the altar and blocked your way. In one hand she was holding a cross while the other kept a bible. Without pausing, she uttered prayer after prayer after prayer.

Ever since you received your title, she was the first person who had the guts to stand against you. You admired that in her. Unfortunately, you could not allow this defiance to continue.

You ripped the bible from her and threw it on the floor, but she kept praying.

You pulled the cross from her hands, but she kept praying.

Even after you slapped her, she didn't stop praying.

Such unwavering strength. But it had to stop, so you hit her over the head. She slumped down **** and that was the end of it.

After you had destroyed the artifact you ordered your soldiers to throw her into a holding cell.
