Lost Sector

Lost Sectors are a PvE activity that will be introduced in Destiny 2. They consist of hidden dungeon areas, which contain enemies and a boss that guards a treasure. Lost Sectors can be identified by a symbol that appears near the entrance, but the difficulty of locating the entrance itself can vary. After entering the Lost Sector and killing its boss, the treasure chest is unlocked.
