A sequel to the maxi-series Crisis on Infinite Earths, this book's purpose was to remove the Justice Society of America from the DC universe, because the writers felt that the team of aging heroes had become irrelevant in the post-Crisis world.
Fifteen members and associates of the Justice Society—Hawkman, Hawkgirl, Flash, Green Lantern, Sandman, Sandy, Starman, Dr. Mid-Nite, Dr.
Fate, Atom, Johnny Thunder, Hourman, Wildcat, Power Girl, and Star-Spangled Kid—are gathered for a private memorial service for the Robin and Huntress of Earth-Two, who had recently been killed in the Crisis.
Feeling redundant in a world filled with younger heroes, the JSA is about to officially disband, when suddenly The Spectre appears to them, apparently fatally wounded despite being a ghost.
Fate then psychically shares this information with all the others, and elaborates as he casts a spell to transport them all through time and space to Berlin on April 15, 1945.
The message was that, while The Spectre was lying unconscious in the cosmic void in the aftermath of the Crisis, his unchecked energy had reached out in space and time, making contact with the Spear of Destiny in 1945 while Adolf Hitler was trying to use it to bring about the end of the world.
The JSA fly up through the hole and find themselves in the realm of Asgard, home of the Norse/Teutonic Gods, who are about to fight their final battle (i.e., Ragnarök).
