They were in such a situation
once before, and found another answer.
However, Tarquin is guilty of certain crimes. If nothing else, he's plotting (and likely has committed) treason against the Empress of Blood, so there's a potential judge. Alternately, Tarquin has recently committed offenses against the people of the Free City of Doom
. It is possible that they may wish to make him answer for his actions under their legal system.
