The Human-Covenant War is over, and the door is open for new insurrections to emerge in its aftermath. The largest and most dangerous of these is a only-rumored radical group known as Operation Underlord, or alternatively, the Dragon Reapers. The reason for the sudden arisal of the latter is still unknown, but may have connotations with the flamethrowers purportedly used by the leaders of this insurrection. As more and more reports of Operation Underlord attacks filter in, it becomes increasingly obvious that Operation Underlord exists in some way, shape, or form, and that the UNSC must do something about this terrorist cell. The Reapers seem well-trained in hit-and-run operations, and it is possible, though ONI firmly denies all rumors, that they may be in possession of top-secret Active Camoflage projectors. It has been all but confirmed that the organization has also attracted several ex-UNSC operatives, and very likely that they have attracted others, including wanted SPARTAN-III supersoldier Xavier-666. The Reapers seem bent on destroying the UNSC from the inside out, and, with the number of likely ex-operatives, they could definitely deal some damage.
