Quest (Destiny 2)

Legacy: The Red War
''Humanity's Last Safe City has fallen to an overwhelming invasion force led by Dominus Ghaul, the imposing commander of the brutal Red Legion. He has stripped the City's Guardians of their power and forced the survivors to flee. You will venture to mysterious, unexplored worlds of our solar system to discover an arsenal of devastating weapons and powerful armor.''

Legacy: Curse of Osiris
Uncover the true story of the greatest Warlock who ever lived, unravel the mystery of the Infinite Forest, and stop the Vex from ushering in a dark future where only they remain.

Legacy: Warmind
''Golden Age satellites slam into the surface of the Hellas Basin on Mars. Icy glaciers thaw, revealing the core of the Warmind Rasputin—and an ancient Hive army, bent on its destruction.''

Legacy: Forsaken
''The death of one of the Last Safe City's beloved leaders unleashes a bevy of unforeseen consequences. Take justice into your own hands as you venture into a new frontier filled with enemies, allies, untold mysteries, and treasures waiting to be uncovered.''

Shadowkeep
''As the heroes of the Last Safe City turn their attention to frontiers beyond the protection of the Vanguard, new Nightmares have emerged on our forgotten Moon. Eris Morn has returned and awoken something that once slumbered beneath the Moon's surface—a long-dormant power that even she cannot control.''

Beyond Light
