In the silent void, a Pilot-Adept attuned to the music of the universe hears a discordant note—a notorious pirate named Gryx Volkov. Her mission: capture or neutralize. But their chase leads them to the desolate world of Oblivael, a graveyard planet harboring the terrifying legacy of a lost civilization and a foe that defies all known laws of physics.

Stranded and broken, they form an unwilling alliance, their opposing natures forced into a jagged harmony of survival. They are the last heirs to a forgotten empire, their unique gifts—her Praxis and his engineering prowess—the only tools capable of deciphering the planet's catastrophic secrets.

Their journey leads them to Nexus Prime, the heart of the cataclysm, where they uncover the truth of a civilization's downfall: a conflict between psychic purists and pragmatic builders that tore their world apart. Now, they must confront the ultimate echo of that failure, a being of pure malice born from a god-like ambition gone terribly wrong.

With the fate of the galaxy hanging in the balance, they must confront the ghosts of their ancestors, harness the opposing forces within themselves, and make a sacrifice that will echo through time, potentially saving all existence from an encroaching, absolute silence.
