In the Barony of Arexa ruled by a Syndicate, a character must undergo a Trial by combat.
He has been framed by A monster or group of monsters - mind flayers, a beholder, giants, a dragon - and if found guilty of Spying, 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.

Barony - The land subject to a baron. Could be scattered across many estates, not necessarily adjacent.
Syndicate - A trade union where the workers democratically run the system or the manager is elected from amongst the workers.
Trial by combat - Fight to the death, winner is innocent
