The year is 950 AD and the story starts in the town of Birka on an island in the great lake which covers a vast area inland of what is today Stockholm. It was a wealthy town at the centre of an international trading network where merchants from as far afield as Turkey, Russia and Ireland met to buy, sell and barter.
The wealth of the island also attracted unwelcome visitors and frequently the Birka warriors had to defend their homes and families against gangs of Viking raiders. The warriors always managed to vanquish the attackers until one day they were tricked by the most feared and fiendish foes, the Jomsviking. These raiders had their base on an island north of what is today Poland and roamed the Baltic waters looting coastal towns and capturing men, women and children to sell in slave markets in Europe and the Orient.
When the adults from the town were kidnapped by the Jomsviking raiders, Ahl, Ingir and their friends manage to avoid capture. They set off in pursuit of the raiders’ ships on a quest to rescue the island prisoners. They avoid capture by a treacherous sea captain and eventually in a dramatic action, manage to free the prisoners.
