Synopsis
For months, the necron terror device known as the World Engine has carved a path of destruction through the Vidar sector. Now, the forces of the Imperium make a last-ditch effort to destroy it. The entire Astral Knights Space Marine Chapter have landed on the World Engine, seeking to annihilate it from within. As a makeshift squad battles necron constructs, long-standing rivalries cause conflict amongst the battle-brothers and threaten to doom them - and perhaps the mission. Can the Astral Knights overcome their differences in time to make a difference?
