In the Emirate of Tamirunt ruled by a Commonwealth, a character must undergo a Trial by combat.
He has been framed by A cult or brotherhood - bound by a mission and code - 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.
