Acheron is a mysterious and accursed world that emerges from the Warp every 5,000 years
In the 41st Millennium Acheron became enveloped by war, once it was discovered that it holds a catastrophic weapon known as the Spear of Khaine. Now the forces of the Blood Ravens Chapter Master Gabriel Angelos, the Eldar Biel-Tan Farseer Macha and the Ork Warlord Gorgutz 'Ead 'Unter, are fighting against each other for possession of the weapon.
When the spear was finally discovered, it revealed to have been a ruse by Chaos forces to unleash a Daemonic horde. Desperate, Gabriel Angelos deliberately crashed a Battle Barge into one of Acheron's fissures, causing the planet to disintegrate.
