Well the phrase "boys will be boys" definitely applied to Vazlyk.  Growing up he always seemed to be getting into trouble either intentionally or accidentally. One day the young goblin, early teens sounds about right, decided to prank the village shaman.  When the shaman had left his home he snuck into the hut and then was distracted for on the table near the door sat the medicine bag.  Instead of going further into the hut he decided to swipe the bag and leave.  After the shaman returned and found his medicine bag gone he investigated and found Vazlyk had it.  Instead of punishing the wiley teen the shaman arranged for him to serve some time at the nearby monestary, which though it was primarily a human monastery they were friends of the goblin village and would willingly accept helping to shape the boys future.

He trained for some years at the monastery and became a trusted member of their ranks.  He would visit his tribe from time to time and became a recognized guardian among them.  The order found he was adept with his scrounging abilities to come up with ingredients and he found an interest in trying to determine what they would do together.   The elder monk taught some of the secrets of alchemy to him.  When the darkness started to overcome the land and threatened the village monks came down to help protect the village from the oncoming assault.  While fighting valiantly Vazylk and the monks managed to save the village, though the goblin defender fell when facing the shadowy leader.

Since coming to this strange world he found the best way to blend in would be in the underground fighting scene.  He found a small following of fans while letting it hone his fighting skills in the event they would be needed for something more important in the future.
