The Earth is in terrible danger. The Babylonian horror Cthulhu has obtained the Book of Planes. With this magical text he can open the very fabric of reality and enter our world through the Domain of Planes to begin a mission of annihilation and conquest our universe has never known before.

The only things standing in Cthulhu's path are three gifted humans and one unassuming, but cosmically gifted young man.

Nirvana, a Buddhist monk who possesses infinite knowledge, Kuun'Liah, the living embodiment of the Earth, and Professor Parker J. McCoy, who can speak every language known to man, must train shy college student John Rourke Harken, The Returner, to utilize his cosmic powers to save the Earth from Cthulhu's unrelenting brand of savagery. It is a race against time to train young Rourke to put an end to Cthulhu's evil forever.

But Cthulhu has plans of his own, for he has amassed an army to assist him in his diabolical plot of eradication and dominion. Can Nirvana and his compatriots train young Rourke in time? Or will Cthulhu's long shadow of evil engulf the entire universe?
