Rock of Eternity

The Rock of Eternity is a fictional location appearing in comic book stories about or relating to Captain Marvel/Shazam! published by Fawcett Comics and later by DC Comics. It first appears in The Marvel Family #7 (December 1947) in the story "The Marvel Family Reaches Eternity".

In the context of the original Fawcett stories published from 1940 to 1953, the Rock of Eternity is the lair of the Wizard Shazam, the ancient Egyptian mage who grants Captain Marvel and his Marvel Family associates Mary Marvel and Captain Marvel, Jr. with their powers. Resembling a large, barren mountain and positioned at the center of space and time, the wizard's spirit remained at the Rock after his death during the initial creation of Captain Marvel, as depicted in Whiz Comics #2 (February 1940). He had previously lived in an underground lair on Earth, accessible by a magic subway car, which included his throne and imprisoned stone personifications of the Seven Deadly Enemies of Man. Following the wizard's death, lighting the brazier in the underground lair would summon Shazam's spirit from the Rock of Eternity; alternately, the Marvels could choose to journey to the Rock itself by flying faster than the speed of light. Surrounding the Rock were mists representing space and time; navigating through them could allow the Marvels to travel to specific locations in time and space.

After a lawsuit from DC Comics forced Fawcett Comics to cease publication of all Captain Marvel-related material in 1953, DC later elected to license the Captain Marvel properties from Fawcett. The Rock of Eternity is used as a locale in some of the 1970s-1980s DC Captain Marvel stories - published under the title Shazam! due to trademark issues with a "Captain Marvel" character started by Marvel Comics while Fawcett's Captain Marvel was out of publication. As it is located at the center of space and time in these stories, the Rock allowed the Marvels and other DC Characters to travel between the various dimensions of DC's Multiverse and travel to the company's various super-hero characters' alternate worlds.
