Vortex Grenade

The Vortex Grenade is an extremely rare and advanced type of specialised grenade used by a few, select individuals in the Warhammer 40,000 universe. The grenade opens a "hole" to the Warp in realspace, which destroys any troops caught in its area of effect. The Vortex Grenade is also an unpredictable weapon in the fact that it not only destroys anything that it comes into contact with, but also that the Warp vortex it creates drifts randomly after activation, slaying friend and foe alike. This grenade, as it might be imagined, is available only to the most high-ranking of Imperial servants, such as the senior officers of Space Marine Chapters and Inquisitors.
