Thor #240

In "When the Gods Make War!", Thor returns to Asgard to find his people trapped in a mysterious lethargy, leaving the realm vulnerable. With help from the Vizier and the guardian Mimir, Thor learns of an ancient threat tied to the Egyptian pantheon and a forgotten pyramid in San Diego. Written by Roy Thomas and Bill Mantlo, with art by Sal Buscema and inks by Klaus Janson, this 1975 Marvel classic features a dramatic cover by Gil Kane and John Romita, and sees Thor confront Horus before a shocking revelation involving Odin himself.
