In a forgotten sector of the universe, the Rosta VI, a scientific cruiser, tracks a mysterious signal emitted by an unknown star. But what was supposed to be a simple exploration mission turns into a nightmare when they discover that this star is not what it seems. Prisoners of an invisible force, the crew finds themselves facing a titanic and terrifying structure: a pulsating black sphere, vestige of a vanished civilization.

When a massive shadow awakens, its red eyes piercing the darkness, Captain Lira Kael realizes they haven't discovered a power source... but a prison. And that they've unleashed something that should never have seen the light.

Isolated in the infinity of the cosmos, facing an ancient and implacable force, will they be able to survive?
