The stories follow Arzach, a silent warrior who rides a pterodactyl-like creature through a strange, desolate landscape.

These stories had an enormous impact on the French comics industry, and the Arzach character is still among Moebius' most famous creations.

The second half recursively introduces John Gerard (a thinly disguised Jean Giraud) and family into the world of Arzach.

Jean Giraud even contributed in the creative process of Team Andromeda's game with original artwork.

Arzach inspired Hayao Miyazaki and he said in an interview that he directed Nausicaä of the Valley of the Wind under Moebius' influence.
