Sarkh (left) with Grahssk on Umbara.
Sarkh is a Trandoshan Pirate who serves under Captain Dheeb in the Battle of Umbara. He can be found in the same area as Dheeb along with Grahssk, and appears to be equipped with the Coruscant Underworld head gear, gloves, and boots, the Balnab Hunter suit, and Han Solo's blaster. If not defeated before Captain Dheeb, he can provide brief health regeneration for him.
