The '''vortex grenade''' is a rare and deadly weapon which utilizes complex warp technology to create a vortex between real space and the [[warp]] on activation. They are very difficult to produce, with only the [[Adeptus Mechanicus]] manufactures them, and are not issued to regular troops, but to important Imperial agents such as Inquisitors or Assassins.{{Fn|1}}

The Vortex Grenade takes the form of a weighty sphere, approximately the size as the fist of a grown man, consisting of an outer shell which encases a delicate and temperamental warp mechanism. The designs of the device date back to the [[Dark Age of Technology]].{{Fn|1}}
