stereotypical badguy setting

You awaken in a dungeon. Yes a dungeon.
There are skeletons and corpses in various stages of rot lying around, many of then still chained up to the walls.
After about five minutes a hideous looking creature takes you to what appears to be an octagonal room with a single crystal ball resting in the middle of it. It's a fairly big room. Big enough for there to be room for all of you and still feel sort of airy in there.
The floor is pitch black, but somehow it feels heated? The walls are decorated with complicated runes and other carved shapes, all glowing strangely red.
On one end of the room sits a magnificent throne, made from wrought iron.
Upon this throne sits, ofcourse, none other than Thistle.
