Helesinine: you have described quite accurately Semola's USUAL place. He sits in my bedroom, that has green curtains, on top of a piece of furniture (partly a cupboard) with all his little friends. Amazing!!!.
Here comes the difficult part. This is really interesting. Royster and Nimue, both your first impressions are right. Though you have said different things you are both describing the location between you. Each of you have made one "mistake", but I cannot correct them without giving out too much information. That's how close you are. Nimue has been more specific on details.
What about colours? Does anything come up?
Anything about the size/general atmosphere of the room?
