World Engine

The World Engine was the name given by the Imperium of Man to a monstrous mobile artificial Tomb World of the Necrons of the Neokhares Dynasty, known to those undying xenos as Borsis. It was discovered in the Vidar Sector of the Imperium in 926.M41 after the Necrons hibernating in stasis tombs beneath its metallic surface rose from the Great Sleep. This Necron planet-sized weapon was armed with an array of deadly Gauss Projectors capable of scorching away all life on the surface of an entire planet. Presenting a hideous threat to the security of the Imperium once its existence was discovered, the World Engine was attacked in the Vidar Sector by 15 Space Marine task forces supported by elements of the Imperial Navy. Despite their best efforts, the Imperial task force was unable to penetrate the World Engines’ superior defences.
