A changer is a Kencyr who followed Gerridon and Fell with him, and who by coupling with the foulest shadows in the farthest rooms of the Master's House has gained immortality thereby and the ability to shape-shift. The changer is warped by this in mind, body and soul, and will eventually lose the ability to hold any fixed shape as the chaotic nature of Perimal Darkling takes over his being.
Changers appear to have had to be Shanir and thus Highborn or part-Highborn. They retain at least some of those abilities including the ability to be bound to a creature. In the case of the changer who is sent to kill Torisen at Tentir in Dark of the Moon, the changer is bound to a wyrm.
Changers are very hard to kill; only fire, or the Ivory Knife, have so far been shown to work. Fire kindles a changer's blood. Their blood is corrosive enough to eat through steel weapons and would be poisonous if drunk. The blood of a Shanir blood-binder, however, if consumed by a Changer, induces excruciating agony and convulsions so powerful that they break bones; it does not appear to kill a changer, but they will seek death rather than endure it.
Changers, it appears, must consume the blood of a person in order to be able to impersonate them. Blood also is food for a changer and they appear to need to consume it in order to regain energy, at least when outside of Perimal Darkling.
Changers who are named include:
- ↑ Dark of the Moon, "Chapter 1: Fire and Ice" — "It was a changer out of Perimal Darkling, she realized, horrified, one of the Master's fallen Kencyr servants. Once this creature must have been as recognizably human as Jame herself, but that had been long, long ago."
- ↑ To Ride a Rathorn, "Glossary" — "Changers: Kencyr who fell with the Master and, through mating with the shadows of Perimal Darkling, have gained the ability to shape-shift"
