10 Warhammer 40k Stories That Would Make INCREDIBLE Movies
3. Cadia Falls
Abaddon the Despoiler launched the 13th Black Crusade in year 999 of the 41st millennium. This would be the largest conflict between the Imperium of Man and the forces of Chaos since the Horus Heresy ten thousand years earlier.
In direct contradiction of many years of Imperial doctrine different high ranking members of the Imperium decided that holding back the forces of Chaos pouring forth from the Eye of Terror was worth a temporary Alliance with different breeds of Xenos. The Archmagos Dominus Belisarius Cawl had been led to Cadia by the Harlequin Shadowseer Sylandri Veilwalker. He decided that investigating the strange pylons present on the planet, with the aid of the Necron Lord Trazyn the Infinite, who had been present when the pylons were first constructed, was worth the risk.
Despite his efforts Cawl could not prevent the forces of Abaddon from crashing a monolithic Blackstone Fortress into the surface of the planet from orbit. Striking on an ancient fault line the Fortress sundered the planet in two. In the end the Imperial Guard stood, but the planet fell. The forces of Chaos continue to spill forth into the Galaxy.
