The path from the northern seas to the southern ones is not easy. Difficult, dangerous... But the one who rides his hailstones and wolves will become truly great. Here it is, the goal of Prince Rurik, who was once called Hrörek the king: power over the waterway, which connects the North with the Byzantine Empire. Jarl Ulf Hviti, the White Wolf, has a more modest goal: to keep the Castle Island taken from the king and with it control over the beginning of another waterway to the southern lands. Unfortunately, the king of the Svei strongly disagrees with the loss of important lands, and Ragnar Lotbrok, who once promised Ulf protection from the Svei, is dead.
