In the March of Tai Quinisam ruled by a Plutocracy, 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 Murder, his punishment will be Wall of Force. The perfect barrier combined with Permanency assuming the other surfaces of the cell are secure. Put a curtain across when you get tired of watching the prisoner make rude gestures at you.

March - Similar to a county, but usually a borderland, ruled over by a marquis. Usually heavily fortified due to it's strategically important position.
Plutocracy - Plutocracy is rule by the wealthy, or power provided by wealth. In a plutocracy, the degree of economic inequality is high while the level of social mobility is low. This can apply to a multitude of government systems, as the key elements of plutocracy transcend and often occur concurrently with the features of those systems.
Trial by combat - Fight to the death, winner is innocent
