Korg is a massive figure standing seven feet tall. His skin is a weathered, dusky gray, marked by several white scars from mountain cats and old clan disputes. He has two prominent tusks jutting from his lower jaw and coal-black hair kept in a thick, utilitarian braid. He is draped in heavy bear furs and worn leather, and he carries a greataxe that looks more like a jagged piece of dark iron than a polished weapon.

Gruff and guarded, Korg rarely speaks and prefers the company of animals to people. He values actions over spoken words, and he is constantly scanning his surroundings for potential ambushes or exits.

Korg was born to the Iron Skull clan, a fierce tribe that valued purity of blood above all else. Though his father was a clan warrior, his mother was a human captive, a fact that his half-brother Thokk never allowed him to forget. As Korg grew in strength and surpassed his full-blooded peers, Thokk grew increasingly jealous of Korg's potential claim to the clan's leadership. During a critical hunt, Thokk sabotaged the party's positioning and pinned the subsequent death of the clan's elders on Korg, making it appear as if Korg had fled the fray out of fear. Following his betrayal, Korg was stripped of his status and exiled into the high, frozen wastes with nothing but his shame. He survived three winters in the wild, bonding with the spirit of the bear to keep himself from freezing. The isolation taught him that loyalty is a weapon that can be turned against those who wield it carelessly. He now travels as a wanderer, seeking a new purpose while secretly hoping to one day confront his brother and restore his honor through a trial of blood.
