Hrungnir was the Chief of Gower during the Great War and during the time of Myth 2 Soulblighter. He was a young and arrogant chief, but the losses of his people in Gower to Balor's forces humbled him and he began to learn humility. During the second war, Hrungnir had aged but could still wield javelins and small forms of shamanism with ease. He fought against the dark with hit and run tactics--some say that he had the blood of Connacht running through him, but this was mere speculation, for Hrungnir's deeds are the only thing that made him akin to Connacht himself.
Speculation
Hrungnir bereft of fear, was the Northman Chief in The Seventh God. Although Hrungnir was used in a plugin, the name and lineage is attributed to the beta tests of the Myth series. Hrungnir was originally suppose to be a special named Berserk, however the developers never got around to adding him in the game. Therefore, it would seem based on his lineage and creative nature--that he was intended to be the Chief of Gower--though this is speculated, the model in the Seventh God and the name fill this gap in Myth's history and canon.
Powers
Hrungnir held a shamanistic scepter that allowed him to shoot out yellow electric rays of fire. He could also throw exploding javelins and was a good fighter in hand to hand combat. All of these traits are what made him an excellent Chief of Gower.
