The Zenith Order, an ancient brotherhood of cosmic warriors who once maintained peace in the galaxy, was thought to have been completely wiped out by the ruthless warlord Lord Drax and his Dominion. However, deep in the ruins of a forgotten world, an orphaned scavenger named Kael Veyne unknowingly carries the spark of the Voidborn—an ancient energy that gives warriors unparalleled strength, telekinetic abilities, and control over the cosmic elements. As Kael discovers his connection to the Zenith Order, he becomes the target of Lord Drax, who seeks to absorb the Voidborn energy and become an unstoppable god-like ruler. With the help of a rogue ex-Zenith warrior, a rebellious starship pilot, and a sentient droid with knowledge of the old ways, Kael embarks on a journey across the galaxy to reunite the surviving masters of the Zenith Order before Drax can consume the last of the Voidborn energy and plunge the universe into eternal darkness.
