As they set out to explore this strange land filled with violent tribes, and vicious creatures, they uncover a brutal regime that takes slaves and technology from every mirror world they can find. They are the enigmatic Sky Lords, and will stop at nothing to destroy the newcomers, and retake the city that links the Mirror Empires together.
