In the 9th century, Ireland was a landscape of fragmented realms, each fiercely independent with its own ancient bloodlines. Five great overkingdoms held sway over lesser domains, yet no single ruler unified the island. This disunity left Ireland vulnerable to external threats.

With the onset of the Viking Age, Ireland faced two hundred years of Norse raids and warfare. Monasteries were plundered, sacred grounds scorched, and peace shattered as northern warriors stormed the land. While some kings resisted, others allied with the Vikings for power.

Among these invaders, Olaf the White emerged as a pivotal figure in Irish history. Revered as a godly descendant, Olaf established himself as the first King of Dublin, forming a Norse stronghold that would influence Ireland's trajectory for generations. Known as Amlaíb Conung, the "King of the Foreigners," his name evoked fear throughout Ireland.

The Saga of the Ere-Dwellers hailed him as "the greatest War King West over the sea." This is the story of Olaf the White.
