Prometheans are the newest threat that will give us a lot of trouble in the game; in case you did not know, a regular Promethean knight is “slightly” stronger than a Elite, and that is already a lot. While it is not clear how these were created, Knights, Crawlers, and Watchers are AI’s. Do not confuse them with the actual organic Prometheans, the ones that created these AI’s. What does this mean? Who knows . . . we might figure it out in Halo 4 or in the new book Halo Silentium (which comes out in January 8th 2013).
