The Fallen have damn near wiped us out. Mara Sov, bless her, saved us. The Cabal have pushed us off of Mars and are ravaging our technologies, firing on anyone, including us, if they get close. The Hive? They killed hundreds, if not thousands of guardians, reaping sorrow, suffering, and corruption. The Vex have sought only to terminate us and wipe us from existence. It is part of their pattern. We do not fit it, so we must be cut away.
