On future Earth, in the North American continent, Human/Eridon half-castes have started to concentrate in disturbingly high numbers. The Great Council of Eridon assigns Ranados Taithlin from the Human/Eridon Half-Caste Team to lead an expedition to discover why.

Ranados gathers together Eridon's foremost Earthian experts; Omadon Delfay and three of his old friends; Aidan Thomas, Katarine of Carcassonne and Con Hatsopopoulos. Together they form the SPecial Advisory Committee to Earth – or SPACE team.

On Earth the team soon discover that the human/Eridon half-castes left behind have managed to master their psionic powers and take control. The entire US has become a gigantic police state with the strongest psyker at the head. The mysterious General Frank Cassidy has been in charge for over a hundred years.

To boost their powers PsiForce scientists created the Dodecahedron – a crude, grisly, but exceptional psionic enhancer. Only the strongest psykers can control it without being torn apart. It is so powerful it must be held on an alternate plane where only PsiForce officers can access it.

Unfortunately the creation of such an abomination has attracted a deadly threat from the very edges of the universe. Beings that feed on psionic energy and swarm to worlds with an overpopulation of powerful psykers are coming, and there are enough of these psionovores to swallow the Earth and drain it dry.

To defeat such monsters can only be accomplished if the psionic fascist General Cassidy and the SPACE team cooperate. But will all their combined mental powers be enough? Or will they need to resort to using the evil device that summoned these creatures in the first place?

The Dodecahedron has the power to turn people into gods.
