The god Nashatay was the god of raiding, revered by the warrior and raider, and hated by those living along the coast. At the fall of the last empire, the sea people were saved by Nashatay leading them north along the coast and gathering gold and food grown by others. Several centuries of living off the spoils of these raids caused the sea people to grow rich, powerful, and feared. Until Ul-Ratha, the Hero of the northerners met a raid lead by Nashatay and his wolves upon the northerners.
Hibron the great wolf of Nashatay bit down upon Ul-Ratha, only to have his jaws rent apart. The sudden death of Hibron lead Nashatay into a bloody rage, charging with deadly intent, his axe cleaving down upon Ul-Ratha. But Nashatay had been betrayed. His lover, Naha, the goddess of the farm and the home, had placed the axe upon a smith's fire the night before. She tired of her husband sending young men to die far from home. The great god of the raid's axe shattered, and Ul-Ratha slew the god. And so Nashatay did die.
And that is how the Sea People began to follow Naha, the goddess of the home, establishing trade and other positive relations with both north and south.
But it turns out that Nashatay had betrayed Naha earlier. He had taken a mortal lover and shortly after he died, she bore the god a son. This demigod has taken the name of Ul-Nash and begun to raise followers to bring back the glory of Nashatay.
Ul-Nash is a berzerker who follows the fashion of the old world. Mostly wearing furs and steel, like no warrior ever did outside of ceremonial conflict. He stands over six feet tall and has been rumoured to be able to lift a yearling calf above his head, a rumour few disbelieve. He claims he was always unhappy working the farm and sought his fortune in the wilds, where he met a wolf pack. His legend then says he was taken into the deep woods where he met the grandfather of the wolves, who claimed he was the son of Nashatay, and gave him the skin of Hibron to wear and honour the companion of his father. His followers refuse to hear any words against this story.
The followers of Ul-Nash are growing slowly, and Ul-Nash has been preaching and recruiting in order to expand his power. The church of Naha has condemned him as a bastard, the illegitimate final sin of Nashatay, and an insult to the god's memory, the cult has declared that the church of Naha is the ignorant followers of a traitor. This conflict will likely come to blows very soon. Ul-Nash's followers are far too few to drag the sea people back to the old ways, but they are numerous and well armed enough that the conflict will be bloody.
