I, too, have a dungeon. It is in the basement and I have enough natural light that I can sew without the electric lights on. However, the moniker is a jest and it was given the title by my husband who answered a phone call from my quilting friend. He explained to her that I was a prisoner down in the dungeon and couldn't talk on the phone or come up from the dungeon until my quilt was done! Of course he was kidding--I was allowed to come up to cook his dinner.
