Games Workshop - Warhammer 40K - 500 Worlds: Titus - The Battle for Unity Begins - Codex - 49-73 - Available January 24th, 2026

By command of Primarch Roboute Guilliman, the ancient empire of the Five Hundred Worlds shall rise anew in the Imperium's darkest hour. Demetrian Titus, now Captain of the Ultramarines Second Company, fights at the forefront of this war of reclamation. Yet the task that lies before him and his battle-brothers is titanic. Upon the blighted world of Novamagnor, Titus meets a malevolent foe in a battle of wits and will. Can he defeat the monstrous Nekrosor Ammentar, its Destroyer legions, and its stygian shards of the Nightbringer, or will Novamagnor and all its defenders be smothered beneath the shroud of death?

This is the first instalment of the 500 Worlds story arc, detailing the brutal and bloody operation to wrest control of Novamagnor from a horrifying new Necron threat. Inside the slipcase, you'll find three books, a booklet, a foldout map, and a sticker sheet to track your game progress.
