Murka was a lieutenant in the Dendarii Free Mercenary Fleet. As an ensign, he served as Bel Thorne's second in command aboard the fast cruiser Ariel. On a mission to Jackson's Whole, Murka participated in a Dendarii raid on Baron Ry Ryoval's main biologicals facility. Captured with two Dendarii troopers by Ryoval's security forces, he talked his way out of captivity by claiming to be looking for a whorehouse. After Admiral Miles Naismith was captured doing further reconnaissance within Ryoval's facility, Murka briefly commanded the Ariel while he was retrieved.
