In the wild & inhospitable far north in the land of Scandinavian myths & runic legends Viking warriors discover a child in a space capsule. Leif Haraldson adopts him & gives him the names of his gods: Thorgal aergisson son of Thor (god of lightning) & son of Aegir (master of the sea). The tale takes place in the seventh centur & draws its narrative power from the imaginary world of magic spells & legends where men & gods mix.
