<begin data stream/ONIFileReport.775/ The Masekii (Latin, Monstrum intrepida, translated to "Fearless Monster" known by humans as Monsters, Reaper, & Shadow) are an unknown species that may have come from the Forsaken Region. As by ONI they have never encountered before or during the Human-Covenant war, nor has the Sangheili. By the end of the war they have simply disappeared and UNSC and ONI recon drones still haven't found their Homeplanet. /end data stream/ONIFileReport>
