There are seven known halos total scattered throughout the farthest reaches of the universe. As you know, one of them's already been destroyed.
The halos are sort of a religious artifact to the Covenant. They were built by an ancient superior race known as the Forerunner, and the Covenant basically worship them as gods, travelling throughout the universe assimilating other worlds and species into their collective race and waging a holy war of sorts with those who would try to resist.
I can only assume the other alien race you're referring to is the Flood? No one knows how the Flood came to be, but it seems that in reality the Halos were built to contain the Flood from spreading off of the artificial ring worlds. If this were for some reason ever to happen, the Forerunners designed the Halos with the failsafe of simultaneously activating and exploding, wiping out not only the Flood, but all life in the universe.
Correct, but 1 problem. Halo doesn't kill the Flood. It kills all other sentient life, which is their food. So it kills their food, which kills them.
