In the Barony of Foiamqua ruled by a Dictatorship, a character must undergo a Trial by combat.
He has been framed by A collusion of guilds - uses resource control for leverage - and if found guilty of Counterfeiting, his punishment will be Imprisonment spell. According to the spell description, the creature is entombed in a state of suspended animation in a small sphere far beneath the surface of the ground. Cast Freedom to release the prisoner. Imprisonment and Freedom indicate you can reach the prisoner, so presumably you can choose the prisoner’s location. This is a perfect setup for dungeon design - put the prisoner at the heart of it.

Barony - The land subject to a baron. Could be scattered across many estates, not necessarily adjacent.
Dictatorship - A state or government under dictatorial rule.
Trial by combat - Fight to the death, winner is innocent
