Durok grew up among the orphans of Kenabres, and that was just fine with him. He quickly learned just how far the overworked guardians could be pushed and always stopped short of drawing attention to himself.
It was on one such occasion that a 14 year old Durok found himself outside the city, hunting rabbits with a few older boys, when the lot were set upon by cultists. A few tried to fight and died, a few, Durok included, tried to run and were captured. Durok spent several days in their 'care', tending the camp, cooking and stoking fires, listening to lessons about the 'great ones', and 'his destiny to serve'. 
Finally after about a week, crusaders found the camp and cut through the  boy's captors in short order. Durok watched in amazement, how could men who had never met each other be so eager to kill each other? 
Thankful to finally be free, Durok Began to leave the horrible scene when a hand on his shoulder stopped him. "Don't you think you owe the Gods a debt, boy?" a bloodied old man spat at him. Durok spent several days in their 'care', tending the camp, cooking and stoking fires, listening to lessons about the 'great ones', and 'his destiny to serve'. 
When the group finally had to go back to Kenebris, Durok used the crowds to slip away from the men. 
From there, he decided that following the God's was for fools, and ignoring the God's was for fools. It would fall on a boy not known for his cunning to figure out how to thread that needle.
When old enough, he stole a few coins and made himself look the part of a passable soldier. It took some creative talking to get his first caravan guard job, but from there, work came steadily. 
Lucky enough to find an actual swordsman, named Gregor, in his ranks on one such job, Durok began to actually learn his profession instead of bluffing his way into jobs. He still talked himself up quite a bit, don't get me wrong, but after a few jobs with Gregor, he actually felt like he could hold his own, should the need arise.
After some time, Gregor moved on and Durok found himself actually craving some real action, profitable action that is. 
No longer satisfied with his paycheck to paycheck existence, he has sworn off large caravans and low paying gigs in favor of  finding a small crew that offers some high risk, high reward potential.
