The Necrons in Warhammer 40,000 are ancient and highly advanced robotic beings with a sinister origin. Originally organic beings, they transferred their consciousness into durable metal bodies through biotransference. Awakening from eons-long slumber, they seek to reclaim their former empire from the younger races of the galaxy. Necrons are characterized by their regenerative abilities, advanced technology, and implacable determination to restore their dominion. They wield devastating energy weapons and are led by powerful overlords and dynastic pharaohs, posing a formidable threat to all who oppose them.
