History of Earth Volume 36,379

History of Earth was a history book written by Kronos Vad, describing the history of the eponymous planet.

A copy of volume 36,379 of this work from an alternate universe that described an invasion of Earth by the Gomagog was found by Abby and Zara at the Archive, and left by them on Earth as a warning, with the hope that it could prevent it from happening in their own universe.

Later, Vienna Salvatori and Bernice Summerfield took the book to the Archive for safekeeping at a point in time before Abby and Zara found it, making its existence a bootstrap paradox. (AUDIO: The Phantom Wreck)
