Background
Sandpoint has a dark side. Many like to pretend that it’s not there. Most will never experience it. It has deep shadows and dark alleys where cut throats and criminals engage in all sorts of shady dealings.
As a poor young half orc, Durbin was involved in his share of shady dealings and bare knuckle brawls. He had the foresight to see where that life lead, though, and wanted more. It was in the aftermath of the ‘Late Unpleasantness’ that he saw his opportunity. The new sheriff was rebuilding the guard force so he lied about his age and signed up. That lasted only until Shalelu saw him and told Sheriff Hemlock how old he really was. Durbin was immediately let go.
Durbin was angry at Shalelu. He decided to let her know just how he felt. He followed her out of town and planned on ambushing her and beating her up. Things did not go as he had planned. At Arrow point through tears of frustration, he explained to her why he was out here and what that position with the guard meant to him. His sincerity touched her. She offered to teach him the ways of the ranger. He wasn’t the best student, but he did learn much. In time, it was time for Shalelu to leave the Sandpoint area. Durbin decided to stay and use his training to earn a living. He’s known as a sell-sword who’s done work as a mercenary, caravan guard, and bounty hunter.
