Halo (planet)

Halo is the basis of all of the HALO games. It is a planet thing shaped like a giant ring. The ring itself has artificial weather and eco system. To the Covenant, Halo has an extremely religious purpose. Built as one of seven identical rings by the forerunners to wipe out all sentient life in the galaxy so in a desperate last resort to rid the galaxy of the flood, the flood may be destroyed by eliminating their food source as prooved by the quote from 343 Guilty Spark, "This installation has a maximum blast radius of 26,000 light, but once the other installations follow suit, this galaxy will be quite devoid of life". As Cortana said, " Humans, Covenant, it doesn'nt matter, they're all equally edible." By destroying Halo, Master Chief, enraged the Covenant significantly, thus the title "demon" was used by the Covenant many times when referring to him. The moniters of each installation will do anything they can after getting the, so-called "Reclaimers" to get the "Sacred Icon". Once the Reclaimers retrieve the icon, the moniters usually attempt to activate halo. The only way to stop halo's activation is to either, destabilize the entire ring by way of explosion or simply toss the Icon into space where it can never be found.
