Hristo Tiktoffen

Professor Hristo Tiktoffen is the man currently in charge of the prisoners in Castle Heterodyne. As such, his responsibilities include keeping track of what piece of Castle controls what other piece of Castle, and keeping track of how many points prisoners have (and thus how close they are to completing their sentences). He lives with the prisoners inside the Castle, leading to the possiblity that he is a kind of senior prisoner himself.

He is also a mole, working for the Council to restore the control of the (or a)Storm King over Europa. As such, his job has been to try and find out how to control the Castle so the Council's fake Heterodyne will appear legitimate.
