Rein searched the body of the guard he knocked out, finding a small key attached to the belt on his waist. He stealthily made his way to the stairs leading down to the basement, where there was a large, underground prison, which was made to harbor the cities criminals until soldiers from the capital came to get them.
There, he saw rows of cells lining the walls, something that he remembered vaguely seeing when he was small, though he wasn't allowed access to it back then. Strangely, there were no guards manning the area, though he still proceeded with caution. The bleak, dimly lit dungeon completely juxtaposed the mansion above, reeking of rats, feces, and rotting corpses. Clearly, this place hadn't been maintained, nor had it been frequented.
