Lost Sector

Lost Sectors are a type of PvE activity that were introduced in Destiny 2. They consist of a hidden dungeon or side area that contains a large number of enemies, a boss enemy, and an unlockable treasure chest. Lost Sectors can be identified by a symbol that appears near its entrance, but the difficulty of actually locating the entrance will vary. Killing the boss inside the Lost Sector unlocks the chest, which will always contain some Glimmer, at least one piece of equipment and a Token for that planet. Lost Sectors can be completed an infinite number of times.
