Eldar

The Eldar, or Asuryani as they were long known to themselves in the Aeldari Lexicon, are a faction of the ancient humanoid alien race called the Aeldari whose vast empire once extended the width and breadth of the known galaxy.

Their empire was without equal, and they counted themselves masters of the stars. But millennia ago, their overweening pride and their fall into hedonistic practices led to a cataclysm that all but eradicated their kind and led to the birth of the Chaos God Slaanesh.

Despite their boundless power, the heart of the Aeldari civilisation was torn out by this catastrophe of their own making, forcing one group of the surviving Aeldari, who called themselves the Asuryani or "Children of Asuryan," to flee upon gigantic, continent-size starships called craftworlds.

Now they cling to survival by a thread, fighting the horrors of the galaxy with ritualised discipline and consummate skill.

Though highly advanced and feared across the galaxy, the Asuryani are a dying people -- a shadow of their former glory -- and their race teeters on the brink of annihilation.
