Season of the Lost

 is the fifteenth season of Destiny 2 and the final seasonal content of Beyond Light, released on August 24th, 2021 and concluded on February 21, 2022. It is longer than Season of Arrivals at 6 months, therefore making it the longest concurrent season of Destiny. During the season, Guardians must rescue the lost Techeuns from the Ascendant Realm as Queen Mara Sov prepares to exorcise a captive Savathûn of her Worm, all while fending off the forces of Xivu Arath.

Description
Story: The Return "Mara Sov, Queen of the Awoken. It would be an understatement to say that much has transpired in her absence. Her brother, last seen lying in rest, walks among the Guardians wearing a new name; Xivu Arath's forces rally in the shadow of the Black Fleet; and Savathûn has been revealed at the heart of the Endless Night. And so, it is now, under the light of a long-awaited sun, that Mara Sov returns to her Dreaming City and seeks an audience with the Witch Queen."

Story: Savathûn, the Witch Queen "Sister to Xivu Arath and Oryx, this family of gods have challenged humanity for centuries. It was Savathûn who defied the Black Fleet, even as it drove a wedge between her and her sister. Although her motive remains obscured, Savathûn's involvement with the Endless Night demands answers."

A Doorway Opens "The crackling of energy echoes throughout the H.E.L.M. as a dark portal makes its presence known within the newly constructed Awoken Wing. Master the tools found here and blur the line between technology and magic."

Activities: Save the Lost Awoken "6-Player Matchmade Activity: Astral Alignment Breathe life into slumbering Awoken technology and triumph over those who fear the Light.

The hands that hold Ager's Scepter hold the keys to areas of the Shattered Realm previously barred. Untangle the layers of Awoken security and reach the Exotic weapon before it falls into the wrong hands."
