Returning What Was Once Taken

As I gazed at the scene in front of me, I shook my head before burning all the bodies. I then sent out my detection magic to check the castle, and I kinda wish I didn't. In one of the dungeon cells in the basement was just a pile of dead bodies. But I did find one cell and one room within the castle that had people in it. I flew over to the room on the second floor that was situated in the middle of the castle.

When I opened the door, a group of girls wearing servant clothes that were skimpier than what the girls at the brothel wore were all huddled together. Each one was around twenty years of age, and some even had wounds on their body. "Please don't kill us! We will do anything!"

I sighed when I saw the fear in their eyes. "I won't be hurting any of you. Can you tell me how long you have been here for?" I asked. I was unsure if it was possible or not, but if I could break the limits of cosmic magic, I might be able to return these girls their youth.
