Highly dangerous warp unit that enslaves the mind of its enemies.
During the War in Heaven, legend tells that the Old Ones engineered new Warp-sensitive species to defeat the C'tan—Krork, Aeldari, Man and more. Yet they bargained without the denizens of the warp, the most numerous of which were the Enslavers or Psyrens. These transdimensional beings were able to rapidly enslave the new races, and hence aided in the downfall of the Old Ones. Today, Enslaver incursions are rare, but extremely destructive unless ended quickly.
