Oubliette

I like a few things about this. First of all, I'd love to have a hole in the floor to keep my pet in before a scene so that she's properly in the mindset. I like the way the shadows fall across her body from the grate over the top. And I like that she has a stool to sit on.

I wonder if she's locked in, or if she can just push the grate up, stand on the stool and get out?

I found this at Onyx Cage.
