The Aeldari or the Eldar are an ancient and highly advanced alien species whose vast empire once extended the width and breadth of the known galaxy in the Warhammer 40k Universe.
In its time, the Aeldari Empire was without equal in the galaxy and even death was no barrier to them.
In the 41st Millennium there are five major sub-cultures or kindreds of the Aeldari species: the Asuryani or Craftworld Aeldari, the Drukhari, the Harlequins, the Exodites, and the Ynnari.
