Sith-makar Forgotten
This creature superficially resembles its tribesfolk, though its posture is hunched and features exaggerated. Most possess exaggerated claws and fangs, their scales twisted and nobby from an overabundance of mana. Their intelligence is merciless and cunning.
Despite their appearance, the Forgotten are a tragic creature. There are two ways the Forgotten may form. The first is through their own desperation; not every sith-makar Awakened, and even some who had, seek to strengthen their own draconic ties. To do so, they begin eating the flesh of their kin. Over time, this warps them and flesh becomes the one thing they hunger for.
Charn discovered this property by accident...but were quick to turn it to their advantage. Captured and force-fed the bodies of their tribesfolk, the Charnese Forgotten are deliberately wrought shocktroops. Those who do not grow claws naturally have leather devices made for them and strapped to their forearms, with jagged edges.
There is no known way to reverse the process.
Mechanically, they are sith-makar with the Vast-wrought template added, and barbarian level(s), so may be adjusted for challenge.
For inspiration, imagine the Reavers from Firefly, or certain creatures from Beastmaster.

Notes
Breath Weapon (Ex): A Vast-wrought creature can spray a 30-foot cone of acidic bile from its mouth as a standard action once every 1d4 rounds. The acid damage caused by this attack is equal to 1d6 per two Hit Dice the mutant possesses. A successful Reflex save (DC = 10 + 1/2 the Mana Waste mutant's Hit Dice + the Mana Waste mutant's Constitution modifier) halves any damage taken from this attack.
Shattered Mind (deformity): The mutant takes a –2 penalty to Intelligence, but gains a +2 racial bonus on Will saves.
