Valkyrie is fading. And Sion is not ready to lose her.

Sion's off to the war-torn World of Rondure to chase a voice that's haunted him for months—one that might unlock his final evolution as the Wind Ruler. But what he doesn't know is Valkyrie's strength is failing, and death is stalking her for the last time.

While Sion fights through smog-choked cities, rogue factions, and interdimensional chaos, Valkyrie prepares to face death alone—before her secret becomes a fatal distraction.

As prophecies close in and ancient powers stir across the Five Worlds, the Chosen Nine must stay united—or fall apart when it matters most.

A war between worlds. A voice from beyond. A love caught between fate and sacrifice
