Astral Knights

The Astral Knights is a Loyalist Space Marine Chapter from an unknown founding and origin. The Astral Knights sacrificed their Chapter to destroy the World Engine. This Necron weapon was a planet-sized spacecraft, armed with gauss projectors capable of scorching planets of all life.

The World Engine
The World Engine was attacked by fifteen Space Marine task forces plus elements from the Imperial Navy, and even the mightiest weapons the Imperial forces could bring to bear could not harm it. Drop Pods and torpedos could not penetrate its shields and it was impossible to lock on to it with teleport beams. The Imperial task force tried twelve times to overwhelm it through sheer valor and firepower and was rewarded with a string of destroyed and crippled ships and millions of casualties. The World Engine destroyed a third of an entire Imperial Navy Battlefleet before the Chapter Master of the Astral Knights decided to ram the World Engine with his Battle Barge. It was only when the enormous Space Marine starship collided with the Necron consruct's shields that they finally failed, allowing the Imperial forces to approach their target. The entire Astral Knights Space Marine Chapter deployed from Drop Pods onto the Necron vessel's surface. For 100 hours the Astral Knights fought against tens of thousands of Necrons and destroyed every flux generator, weapon forge and command node they came upon. Only after the Chapter had been reduced in size to the Chapter Master and five Battle-Brothers did they succeed. The Chapter Master detonated melta-charges that destroyed a vast tomb complex that housed many of the World Engine's command arrays and thus brought down the vessel's void shields which allowed the Imperial Navy's starships to destroy it with cyclonic torpedoes.
