Wraiths

Wraiths are the army of the Nightbringers. They were once Mortal, Blue Mages of the Rose Protectorate. But when the Tower fell, many of them perished. Their souls were held in a compendium buried deep within the Protectorate, and then brought to the Red Mountains where Hesse personally oversaw their creation at the Icebox, an Order outpost and prison converted into his personal factory outside the Hollow Mountain's walls.

From there, they were shipped to Fulminaria, where at an undisclosed location, they were blessed by Dusk and awoke to new purpose.
