He had lived all his life as a castaway from his brethren for the rumor of his Dwarven ancestors, and thus had had to fend for himself.

Olfin stands at 5' tall, and bears with him a Dwarvish battle ax, also giving fuel to the thinking that he is indeed half Dwarf himself. It hardly comes time for him to swing his blade, for most are terrified at the mere sight of him. Though for as small as he is in height, his head is twice the size of the average man, and his arms the size of most men's legs, giving him a wide sense of presence. Only to add to that is the fact that his boots, shoulder plate, and ax are made of iron, making his a deadly path to cross.
