In 3643 BBY, Muwn was assigned to track down the notorious criminal Skavak, who had stolen the Murustavan Ruby, a priceless, unique gem mined millennia ago. The Constable Brigade gave him significant leeway in tracking him down, allowing him to travel offworld and enlist the aid of Republic citizens along the way. He was limited in certain ways, however; he had to yield to local constables while out of his jurisdiction.
