Siege (The Pack/Team Crafted)

Mankind split after the third World War. The winners stole technology from the suppressed and used it to their own advantage, creating a human supreme race able to bend and control the very elements of life itself. Those who had been attacked and gutted fell to the grounds and devolved, becoming primitive and starting the million-year-long process of evolution all over again, but with a twist.
The Overlords and their Subspecies. They never interacted, not for a very long time. It changed, however, when one tribe got too close to the supercity of Shakel. What started as a minor skirmish became the entirety of another World War. Basic religion and finite survival skills had made the Subspecies stronger than the Supreme Race had hoped for.
Finally reaching a tipping point in the war, a peace treaty was signed, causing six of the most valiant fighters to be pulled from the War and sent to spread word to the rest of the world.
Unfortunately, nothing ever goes as planned.
