Wraithguards

The Wraithguard of the Craftworld Aeldari are not living warriors; they are artificial robotic constructs called Ghost Warriors created from the complex psycho-plastic material crafted by the Asuryani of the craftworlds known as wraithbone. Each Wraithguard has a Spirit Stone containing the soul of an elite Aeldari warrior that was drawn out of the Infinity Circuit of a craftworld.
