A Nighthaunt Procession is the name for a military force of the Grand Alliance of Death comprised of the spectral Undead known as Nighthaunts. They serve the deity Nagash, the Supreme Overlord of the Undead and the ruler of the Mortal Realm of Shyish.

The Nighthaunt is composed entirely of spectral Undead known as wraiths who hate the living due to all that they suffered, or believe themselves to have suffered, during their lives.

The stench of open graves and mildewed cloth, the unnatural chilling of the air along with the clank of chains and unearthly moans -- these announce the presence of the wraith host.

Directed by more powerful wills or by their own malicious instincts, the wraith hosts of the Nighthaunt processions come to extinguish life wherever they find it.
