"The weapon is a recovered Archeotech product of the Dark Age of Technology and looks like a large ballistic missile mounted either on a Titan weapon hard point, or a Deathstrike Missile Launcher. The payload of the weapon is no mere explosive, but a complicated mechanism which shows many similarities with the Warp-Drives that allow the Imperium of Man's starships to travel between the stars. Once detonated, the warhead's mechanism opens an uncontrolled "hole" into the Warp from real space, which utterly annihilates anything caught in its area of effect."
