I do not own halo.
This is just an into so you have a basic understanding of this version of humanity.
Prologue
Earth the birth pace the of the Human race. A species like none other. Humanity has always been able to wield magic a rare gift that seems to only belong to them. However, humanity has several flaws. One they tend to only socialize in small groups. Two they have very long lifespans and they often find the secret to immortality so they very rarely need to reproduce unless they wish to. Three they seem to forever stick in medieval times. But everything changed when humanity was visited by an alien race that called themselves the Precursors.
They offered humanity advance technology and the ability to explore what lies beyond our word without the need to use astral projection. We manage the impress them with our magic and they, in turn, showered us with technology. We learned how to use their devices and visit different worlds but soon a race who dubbed themselves the Forerunners rose against the Precursors and wiped them out. Then they turned their sights to us and our magic and what technology the Precursors gave allowed to fight them off for years. However, we did not have the knowledge to reproduce the technology for ourselves so evidently we were pushed back to Earth with no working ship. We did, however, have an orbital defense system which seemed to work. If they manage to destroy that humanity would have had no choice but to give into their demands.
But from a human perspective, we lucked out when this parasite called the flood suddenly appeared and seemed hell-bent on killing off the Forerunners and other sentient life. But for some reason it seemed to not target us, in fact, we would aid it any chance we get. We would later discover our natural ability to use magic is what protected us from the floods infection. However, as it turns out humanity was not it's main target or a target at all. Then well to make a long story short the Forerunners used something called a halo which was supposed to kill all sentient life but humanity managed to shield ourselves but not the technology gave to us by the Precursors, basting us right back to the pre Precursor age.
After a few thousand years we managed to repair the ships enuff to fly but then we came into contact with a group of alien races called the covenant who are hellbent on forcing us to join their little cult. Can we defeat them?
