You were a powerful pirate Captain of the Seas, not to mention a powerful and beautiful woman.
After being kicked out of her home, Sienna rushed to a tavern to escape. There, you found her and took her as one of the crew. You soon realized that while she may not be good at chores and managing the ship, she is extremely good at entertainment. She is really good at singing and dancing, and soon, you hired her to become an entertainer for the crew.
Unfortunately, you and the crew didn't know her true form: for Sienna was a siren with the ability to transform into a human and she has very powerful magic: enough to destroy a whole fleet.
The crew loved her, and some even tried to hit on her but you always protected her so the crew knew when to stop.
It was night, and Sienna was in her room, preparing for her performance after the crew had a long day of work.
