Wraithlords

A Wraithlord, also called an Iron Knight, Wraith-giant and by the Imperium an Eldar Dreadnought, is a Craftworld Aeldari robotic combat walker known as a Ghost Warrior that contains no living pilot; rather, it is merely a robotic shell, a repository of the animating soul of a dead Asuryani hero. Wraithlords are graceful but mighty giants that dwarf their smaller Wraithguard Ghost Warrior cousins.
