In the Fief of Nonide ruled by a Technocracy, 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 Bestow Curse. The prisoner loses 6 off his ability score. That is devastating, possibly cutting it in half or worse. Forcing them to become an imbecile is a good way to keep the person useful doing menial chores without needing high security. The GM can also craft their own Curse effect, such as 50% chance of lying down every six seconds - it’s hard to escape while taking a siesta.

Fief - Land or office granted to a vassal. Ownership is technically still with the granting lord, but revenue and production is given to the vassal. The lord technically retained the right to seize the land in case of disloyalty.
Technocracy - Technocracy (bureaucratic), a governmental or organizational system where decision makers are selected based upon how highly skilled and qualified they are, rather than how much political capital they hold. A form of government in which scientists and technical experts are in control; "technocracy is described as that society in which those who govern justify themselves by appeal to technical experts who justify themselves by appeal to scientific forms of knowledge"
Trial by combat - Fight to the death, winner is innocent
