Led by Morayne, the Blade of Twilight, the Ghosts of Ios are a ragtag band of refugee mage hunters who have devoted themselves to the protection of all living Iosans. Ranging between the refugee camps of Llael and Rhul and the former Skorne territories in the Bloodstone Marches, the Ghosts operate at the fringes of the Empire of Eternal Dusk. Working in loose coordination with House Kallyss and the other members of the Court of Dusk, these former members of the Retribution of Scyrah strike at their shared enemies to preserve the legacy of the Vanished Gods.

The Ghosts of Ios cadre includes Morayne, the Blade of Twilight (warcaster), the Mage Hunter Assassins and Mage Hunter Rangers (units), the Mage Hunter Sniper Team (solo), Mage Hunter Commander (solo), Vaelyss, the Hand of Mourning (character solo), and the Specter (light warjack).
