In the wild and inhospitable European far north, in the land of Scandinavian myth and runic legend, Viking warriors discover a child in a space capsule. Leif Haraldson adopts him and gives him the names of his gods: Thorgal Aegirsson, son of Thor (god of lightning) and son of Aegir (master of the sea). Upon Leif's death, the Viking chief Gandalf the Insane isolates Thorgal from others. Only the friendship of Aaricia, the daughter of Gandalf, brightens Thorgal's solitary childhood. Their mutual affection quickly turns into true love.
The tale takes place in the seventh century and draws its narrative power from the imaginary world of magic spells and legends, where men and gods still mix. More than a simple adventure story, this series is a true apology for freedom and the fight against the arbitrary, because what stands out most in Thorgal's personality is his deep sense of humanity...
