SPHERE OF MYSTERY . . .
On a lonely moon in deepest space a scout for Perry Rhodan's fleet encounters a strange, sentient orb. As a Springer attack force approaches the planet Goszul, the orb reveals its awesome power . . . but what are its intentions?

Meanwhile on Goszul, the Springers seem to have been vanquished by the Plague of Oblivion unleashed by Rhodan and his mutants. But the Springers have one devastating card left to play – hidden deep in the mountains, their mightiest battleship is nearing completion . . .
