Prisoners here seem to vanish or at least be "corrected" by the tender mercies of the Monquisition.
What is this prison based off?
That's right. There is a book called "The Prisoner of Zenda".
In this book though, Zenda is not a prison, but a small town. The king in this book was sent to Zenda and was trapped there.
Will King Fernando be trapped in Zenda? I hope so, and I really hope Queen Isadore is trapped with him!
