Panopticon is currently a dead site, though there are hopes of reviving it.

Panopticon is a prison set in a fictional medieval to victorian times world. The country outside the prison is rarely discussed, because once you're in panopticon, you're in for life.

Panopticon is a unique roleplaying site based on research, meant to explore the psychology of characters in prison. It's a fantastic site, sadly declined. We'd love to see it revived.
