What's gone on before...
19 years ago, the forest giants of Dregar banded together to form an overly confident raiding party under the poor leadership of their chief. Their target was the small village of Orc's Watch on Dregar. Their continued attempts were ever thwarted but during the last wave of attack, they stole from the town, a brilliant young female sword master. It was her fate to suffer the ravages of giant pregnation and her ensuing death during child birth.
Gor was born into the land. The bastard son of just another lusting battle giant and a woman who's name was never known or would be now long forgotten. He was named for simply for the mess he made, struggling into this world.
Gor was no giant among giants. Bald and darkskined, Gor is definitely has not come to his full size as a giant. Maybe not as strong or as big as even other half-giants. Although certainly large, he had a wit about him. Maybe it was that bit of dazzle in his eye or maybe the way he moved, but he was different then all of the rest. The other giants would simply never understand.
Raised by his giant brethern, he grew up as giants did, fighting and bouldering and eating and such... but games such as that bored him. Maybe it was because he was a halfer but he knew the world was bigger than his next dinner on the side of a cliff. He knew he would one day leave this clan and seek out the world at large.
Yes, Gor had something between his ears even as half-giants went. He was no scholar but a man of tactics. When the larger, stronger giants would test him, it was not the toe-to-toe battle but the little ways he could evade his opponent, maybe throw off his balance or lead him in the direction he wanted. Oh, the twist and whip of a wrist. The angle of the elbow. The dip of a knew, twist of a hip, or drop a shoulder...a wink here, bend there, and the dance of the sword would begin. Oh what rapture to understand the battle blade, to be one with it and as it was whipped about it with frightening ease. Yes, his training and practicing with a sword and shield was a natural thing and something he thought he might get better at some day. Not the bashing method of a barbarian like his brethen.
When he had come of age, it was a natural thing to leave his clan. They could see it from the glint in his eye. A giants life was too dull to keep this halfer close to the clan. Besides, they all knew he didn't fit in. Small, smart, agile, ... not a giant among giants... but who could be a giant among men.
With no love of the giants who took his mother, and less for the humans who now spur him, he's alone. He goes on. The dark curious type, adventurous, and looking for the next foe to fall as he learns his sword. He will test himself against what the realms have to offer or crash to his demise.
