Astral Knights

Overview
The Astral Knights is a 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 spaceship, armed with gauss projectors capable of scourching planets of all life.

The World Engine
The World Engine was attacked by fifteen space marine task forces plus elements from the imperial navy, even the mightiest weapons 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 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 Battle Barge collided with its defense screens. Once inside the shields did the Imperial forces have a chance. The entire Astral Knights space marine chapter deployed from Drop Pods onto the engines 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 was wiped 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 bringing down the shields and allow the navy to destroy it with cyclonic torpedoes.
