In an event that has sent shockwaves through the galaxy, Lionel Johnson, the lost Primarch of the Dark Angels, has emerged from his long exile. After being lost for thousands of years, Johnson has returned, potentially altering the course of the Imperium of Man in ways no one could have predicted.
Once believed to be dead, Lionel Johnson vanished following the Great Crusade, disappearing into the mysterious depths of the Imperium after a self-imposed exile. It was thought that Johnson had perished in the aftermath of his final confrontation with Horus during the Horus Heresy, but recent reports confirm that the elusive Primarch is alive—and more powerful than ever.
Sources within the Adeptus Mechanicus have suggested that Johnson’s reappearance was tied to a psychic resonance detected deep within the Rock, the Dark Angels’ fortress-monastery. For unknown reasons, the Primarch, believed to have been in stasis or hiding from both enemies and allies alike, has resurfaced in the wake of the Imperium's most recent crises.
