This is the evil that awakened in Halo 4
Meet the Diadact, the bad guy of Halo 4 and the ever loving husband of the Librarian.
The Didact was a Forerunner Promethean who held an extremely high status in the Forerunner society as supreme commander of the entire Forerunner military. There's a huge back story but eventually he took control of the body of Bornstellar Makes Eternal Lasting (refer Halo: Cryptum) and set about laying plans to finish off the Halo programme.
By the time the Diadact finally meets the Master Chief in Halo 4, his actions across the milenia have seen him defined as the bad guy of the Halo universe.
