In the Caliphate of Dita ruled by a Theocracy, a character must undergo a Trial by combat.
He has been framed by A collusion of guilds - uses resource control for leverage - and if found guilty of Terrorism, his punishment will be Insanity. The imprisoned can only act normally 25% of the time, and their state of mind changes every six seconds with equal chances of babbling incoherently, hurting themselves or attacking someone else. Being imprisoned in your own skull is a harsh sentence.

Caliphate - A land area taken care of by the caliph, who is elected through local leaders as in a republic. The caliph is bound by the laws and not above them.
Theocracy - Theocracy is a form of government in which a 'god' or 'deity' is recognized as the supreme civil ruler. For believers, theocracy is a form of government in which divine power governs an earthly human state, either in a personal incarnation or, more often, via religious institutional representatives (i.e., a church), replacing or dominating civil government.
Trial by combat - Fight to the death, winner is innocent
