Lucius: Pride and Fall (Warhammer 40,000)

The armour of Lucius the Eternal is a mosaic of howling caged souls – warrior-kings, champions of the Legions and master assassins, whose triumphs over Lucius were rendered into their doom by the will of Slaanesh. Of all the faces screaming from within the ensorcelled plate, one stands apart. He commanded no army, and was master of neither bolter nor blade. Who was he, and what twist of fate led him to be bound within the endless prison of the Eternal?
