It was written by Mark Waid, Tom McCraw and Kurt Busiek, with pencils by Stuart Immonen, Ron Boyd, Chris Gardner and Colleen Doran.
A tie-in to the Zero Hour: Crisis in Time miniseries, it is the final story in the Legion of Super-Heroes' original continuity.
[4] The SW6 Invisible Kid and the two versions of Brainiac 5 interrupt the funeral to inform them that the timestream has become fractured, and that an unknown force has been shifting reality for years.
Computo and Tyroc open a gigantic wormhole, permitting Valor, the SW6 Andromeda and Dev-Em to tow Earth from the pocket universe to the regular one.
Mysa Nal, Princess Projectra, Dragonmage, and Dream Girl channel their energy into Devlin O'Ryan to stop the two, but he fades away, leaving the mystics with no focus for their magic.
In the 20th century, the founding SW6 Legionnaires (Cosmic Boy, Saturn Girl, and Live Wire) emerge from a shattered Time Bubble above the Earth.
[8][9] Eventually, the Trapper's attempts to protect time drove him mad and allowed Mordru and Glorith to become galactic threats.
It is revealed that the Time Trapper is Cosmic Boy's future self and that the Legion and their SW6 counterparts must fuse to restore the timeline.
Following Infinite Crisis, much of the original Legion continuity is restored,[10] but "End of an Era" is not, and the story arc is no longer considered canonical.
