The Wraiths are associated with the Valkyrie, used to protect their homes. In exchange the Valkyrie provide a lock of their hair to enter. The Wraiths turn the hair into a braid which when at a certain length allows them to control all Valkyrie for a time.
It is implied that they were not always Wraiths as they appear as Lothaire recognises one from when she "was pretty".
