Fury of Deimos
The Fury of Deimos is a relic of the Grey Knights. When the moon of Deimos was gifted to Titan by the Adeptus Mechanicus, it carried with it a ship loaded with some of the finest weapons the Imperium has ever created. Among them was the storm bolter Fury of Deimos, a weapon crafted by the first Fabricator General. Superior in range, accuracy, rate of fire and reliability to a normal storm bolter, it is a relic whose secrets have long been forgotten.
