In the Archduchy of Potem ruled by a Military Dictatorship, 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 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.
