Gi - Halo 5 fans wondering what The Arbiter has been up to since signing a peace treaty with Admiral Hood and returning to Sanghelios (the Elite homeworld) need look no further than the Halo novels. Imagine that after thousands of years of training an alien race for military positions, the system that required those positions collapses leaving the majority of those aliens jobless. Then imagine that as a result of that collapse, most of that race’s labor force, comprised of other alien races, dries up leaving no training manuals behind. So far not good right? Now imagine that these same aliens have been hard-core religious for thousands of years and they just found out their religion is bull. This sums up what has been happening with the Elites since the end of the Covenant war with the humans.
