Where is she?

When Cassandra opened her eyes, she felt a sharp pain on the back of her head. It felt as if someone was hitting her head with a hammer. Her hands were tied and full of red welts. Her legs were bound too. She looked around. It was a dungeon. A smelly dark place with a

small flame burning on one end near the door. There was a small skylight above. The early morning light was streaking inside from it.
