Warhammer 40,000's space fantasy is set in a fictional future during the 41st millennium AD. Its various factions and races include the Imperium of Man, a decentralized yet totalitarian interstellar empire that has ruled the vast majority of humanity for millennia, the Orks (similar to Warhammer Fantasy Orcs), the Eldar (similar to Elves in Warhammer Fantasy Battle), and Daemons (very similar in both the Warhammer 40k and Warhammer Fantasy Battle universes, although the precise natures of their creation and existence vary slightly), among others. The background and playing rules of each faction are covered in the game's rule books and supplemental army 'codex', along with articles in the Games Workshop magazines, White Dwarf and Imperial Armour. The game's miniatures are produced by Citadel Miniatures and Forge World. Legend says that the Howling Banshees Aspect was first created when the Eldar Crone Goddess Morai-Heg desired the knowledge contained within her own divine blood and to this end sent her daughters, the banshees, to haunt their father, the War God Kaela Mensha Khaine, as he was the only being capable of harming another God. Seeking to end the torment caused by the banshees' constant wailing, Khaine decided to grant Morai-Heg her wish and severed her hand, which allowed her to drink the knowledge contained within her own blood. Shuriken Pistols are graceful dealers of death that use sophisticated gravity accelerators to hurl volleys of miniature razor disks to literally slice their victims apart in seconds. Shuriken weapons use solid core ammunition which Imperial technology cannot replicate. When fired, a shuriken pistol unleashes a hail of razor-sharp monomolecular discs known as shuriken.
