In the Duchy of Sipetuam ruled by a Republic, 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 Treason, his punishment will be Flesh to Stone. Perfect for filling an art gallery or museum. Under careful watch of security to prevent an ally from casting Stone to Flesh, prisoners can be put on display as an example to all, or kept in a private collection for the warden to gloat over or decorate as he sees fit.

Duchy - The dominion of a duke, who is the highest ranking noble not in the royal not in line of succession.
Republic - A republic is a state or country that is not led by a hereditary monarch,12, but in which the people (or at least a part of its people)3 have impact on its government.
