Editing Eldar Warhost (Imperium Asunder) (section)

==Ghost Legions==
Often pointed to by Eldar beyond the Imperial territories as a clear sign of the Empire's certain fall into degeneracy, the Ghost Legions are nonetheless essential to its security. Once a practice of last resorted, whispered of as a dark, necromantic art, the interment of the Eldar soul within a frame of wraithbone has become a commonplace practice within the Empire. Foundries across the Empire churn day and night, ensuring that ''every'' fallen Eldar, regardless of rank or role, can be called upon to don a form of tempered wraithbone and fight along their descendants (though, for most, this is temporary. With the exception of Biel-Tan and Kher-Ys, the Imperial Eldar do not expect their ancestors to serve constantly, and for most their time as Wraithguard is a brief outing). Equipped with ever-more specialized and varied equipment, these undead warriors are set apart from the standard warhost structure, organized into Ghost Legions and commanded by Spiritseers or Wraithseers - or, in particularly rare cases, Wraithguard heroes of such will and strength of character that they retain all the clarity of life even in death.

The use of Ghost Legions differs from Craftworld to Craftworld. Biel-Tan regards the safety of the Empire as its eternal responsibility, both in life and in death, and its Ghost Legions see by far the most battle, often equipped with Aspect weaponry. Kher-Ys seems to see little distinction between the living and the dead, and it is unknown if its Wraithguard ever retire to an Infinity Circuit - or if the Craftworld even has one anymore. Iyanden, with its massive population and many Starholds, makes the least use of the Ghost Legions, but still deploys them in times of need.
