Obviously I am still working on making them bigger and more legible.....
Gith Hunter Fluff: An experienced Gith is a dangerous foe. It has watched many of it's tribemates get eaten by the myriad of predators on Athas, and it has learned from every experience. Gith Hunters use their mobility to harry foes, striking and darting away, but do not mistake their tactics for cowardice, these Gith are just as bloodthirsty as their tribemates.
Gith Warrior fluff: A Gith Warrior is a more disciplined Gith than usual. It has been trained to harness the ability of it's mind to form a blade of psychic energy. They are taught to protect the more valuable drones and psykers of the tribe, to clear the path for the brutes, and to keep foes away from the hobblers. After all, a tribe that hunts well, eats well.
Gith Psyker fluff: Some Gith with psychic potential are trained as Psyker's, to unleash their bestial nature through the power of their mind. The psychic barrage they unleash can overcome a weak foes mind, or strengthen allies while assailing foes. Psykers relish the ability to unhinge their minds. They just as canny, cunning and savage as all Gith. A tribe may contain both Drones and Psykers, but they rarely work together, as Psykers feel superior to the drooling drones.
