Vinland Saga follows young Thorfinn, who grows up listening to old sailors tell stories about Vinland, a legendary land said to be warm and fertile—a place where there would be no need for fighting, nothing like the frozen village in Iceland where he was born or the mercenary life he lives now. In Thorfinn's world, war has become ordinary, and the vow his father once taught him—"You have no enemies, nobody does. There is nobody who it's okay to hurt"—sounds almost impossible to believe.
As the war between England and the Danes drags on, death becomes commonplace and the Viking mercenaries thrive on the conflict. They throw their weight behind whichever side will shift the balance of power, all while chasing spoils, fame, and the next battle. Caught in the middle, Thorfinn is driven by revenge: he wants to kill Askeladd, the man who murdered his father. Yet the legend of Vinland keeps pulling at the story, offering a distant image of a world beyond the violence, even as the era around him remains a paradise for vikings built on war and death.
