In an alternate universe where Nightmare Moon defeated Celestia, a cold war has erupted between Moon's triumphant followers and the outnumbered followers of Celestia. Marble, not wanting to fight, took up a role as a scout and courier. She was pretty good at her job, but she was captured in an ambush by a dozen of Luna's best guards. After a brief show trial, she's been sentenced to life imprisonment for the crime of supporting the Solar tyant.

After being secured in her new, permanent straitjacket (magically enchanted to prevent circulation problems in her arms), Marble's transported to prison, where a nice, comfy cell has been prepared for her. Surrounded by guards, she nervously eyes her new home, knowing that once she walks inside, she'll never walk out.

Unknown to Marble, though, her friends in the resistance are already hard at work planning a rescue. But will they be able to sneak inside, bust her out, and flee to safety, or will they become permanent residents as well?

Another straitjacket test done using this photo. I think it turned out better than the last one.
