Astartes

• Specialized fighting force of The Empire
• An experimental elite fighting force created by the Emperor to fight against the Weaving Order without exposing the Brotherhood of the Warp. Although many species were tested on, humans were the only successful subjects 6 Legions in total, with 15,000 Astartes per legion and led by a Primarch. During the Galactic Civil War, 3 legions turned against the Empire after discovering they were fighting an unjust war, not quite allying themselves with the Weaving Order, but aligning themselves with the teachings of Ashla. These post-humans were hunted relentlessly by their  loyalist brothers and now it is not known how many of the Rebel Legions are left scattered throughout the galaxy.**
