"Jonathan Agrivar", as he was known at birth, was born to a human farm woman whose husband died in the raid during which she was raped. She named her son after her dead husband. Jonathan grew up spending the vast majority of his time helping to work the farm, but he went exploring the neighboring woodlands and hunting when he wasn't plowing or planting. (Mom figured she'd better get some work out of the b****rd since his daddy killed her husband.) She loved her son Jonathan as much as she could under the circumstances, but she never let him feel like he was accepted unconditionally. It was always more like, 'well, yeah, this is the cruddy hand I was dealt, so I might as well learn to like you, ya little b****rd." After his mother fell ill and died, there was no way in h**l that the village was going to let him inherit the farm. (Now, they would have been tickled to have him "buy the farm," but only in the euphemistic sense.)
Jonathan's socialization suffered because of his isolation down on the farm. He is only just barely able to be tolerated by "polite" company and the feeling is very mutual. Jonathan became a major loner and prefers to be alone and outdoors if at all possible. After his mother passed away, Jonathan's curiosity overcame him, and he sought out his orcish father to learn more about himself and his origins. He found him after some weeks of searching, and his father, Melluce Blacktusk, claiming the right of fatherhood, bestowed upon him the name Besharrn Blacktusk
. Besharrn was only too glad to be rid of a dead man's name, and he especially liked it when his father told him that he was named for the sound his father's greatsword made when drawn to do battle. Besharrn's father approves of his skill with the halberd and looked with pride on his son when he showed him his "shield of swings" maneuver. But Besharrn soon wearied of Orcish life and longed to be able to conduct his affairs without the constant, nagging fear of a knife in his back or a slit throat in the night. So, as soon as he could, he made his peace with his father and his father's life, and the two parted amicably, though both know that if they ever meet again, it will likely not be a peaceful meeting and one of them will likely not survive it. Besharrn also knows that he has a number of brothers in the world, but he did not bother to learn any of their names or locations. 'Best to just kill them and have done with it,' he thinks.
In an adventuring party, Besharrn recognizes his dependence on the other members, but that doesn't mean he has to like it, and he'll gladly volunteer to pull as many shifts on watch as he can stand just so he can get in some quality time with his best friend -- himself. Plus, he's not a bad dude to have on watch, so it should be a definite win-win. Besharrn, having left Orcish life behind him and come into the light fully, hopes to make some genuine friends among his adventuring companions. He's never really had a friend before, so this will be all new to him.
Currently, Besharrn, or 'Jonathan' as he will most likely need to introduce himself, has traveled to attend the reading of the Last Will of Professor Lorrimor, who was a cousin of Besharrn's/Jonathan's mother. The Professor visited their farm a few times, and he was impressed by Besharrn's/Jonathan's hard work and his willingness to scratch out a comfortable living on the farm, because that was not at all what he had been told to expect from such a half-breed. Besharrn/Jonathan had not seen the Professor for a number of years. He really does not expect to be named as an heir in the will, but he thought it would be best to attend the memorial service for his mother's sake, since she did love the Professor dearly and often spoke of him fondly.
