The Pathfinders

Colonel John Haverson is a Pathfinder. Part explorer and part soldier, Haverson is one of the Coalition Navy's elite. Commanding the Frigate, Relentless, the Colonel and his crew travels the new frontier in the name of humanity. 

While on Fulcrum, the Pathfinder base, the Relentless is assigned a new medic, Doctor Miles Wexler.  A civilian outside the Navy chain of command, Wexler has volunteered himself to the Pathfinders. Bored as a surgeon on Osiris, the young man is keen to see the galaxy while contributing something in return.
