The Ghosts of Nocturne are a fleet-based Primaris chapter descended from the Salamanders, forged during the Ultima Founding and shaped by harsh training under Raptors command.

Masters of stealth, close-quarters combat, and guerrilla tactics, they strike with silent precision before vanishing into darkness. Despite their shadowy nature, they revere fire as a spiritual force—using it in sacred rituals like the Cleansing, where they bathe in flame to find clarity and, at times, prophecy.

Their recruits hail from Vespera IV, a feudal jungle world whose mysticism and resilience now pulse through the chapter's evolving culture. Gaunt, grey-skinned, and ghostlike in form, they live up to their name—haunting enemies like specters in the night.
