In the Fief of Pocre ruled by a Coalition, 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 Embezzlement, his punishment will be Trap the Soul. Put the prisoner into a gem. Break the gem when the sentence finishes. Note the gem must have a value based on how powerful the prisoner is, but the type and shape of the gem remains up to you. Perhaps those glowing red gems in the horned demon statue’s eyes have more than just good market value….

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.
Coalition - A coalition government, in a parliamentary system, is a government composed of a coalition of parties. A coalition of parties is also an electoral fusion. The union of different political parties or groups for a particular purpose, usually for a limited time.
Trial by combat - Fight to the death, winner is innocent
