In the County of Spesracuut Depotus ruled by a Totalitarian, a character must undergo a Trial by combat.
He has been framed by A magic item - sword, relic, wondrous item - 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.

County - The land ruled over by a count (or earl, in some areas).
Totalitarian - Totalitarianism (or totalitarian rule) is a concept used to describe political systems where a state regulates nearly every aspect of public and private life. Totalitarian regimes or movements maintain themselves in political power by means of an official all-embracing ideology and propaganda disseminated through the state-controlled mass media, a single party that controls the state, personality cults, central state-controlled economy, regulation and restriction of free discussion and criticism, the use of mass surveillance, and widespread use of terror tactics.
Trial by combat - Fight to the death, winner is innocent
