Twenty-eight minutes — the longest cinematic session, the Forsaken opening, the murder that defined Destiny's most acclaimed expansion. The war in the sky is the ongoing conflict that Cayde's death reorganizes from a distant abstraction into something immediate and personal. Running out of air is both literal (the vacuum of the sky) and the pressure of the moment: the City's resources depleting, the alliances fracturing, the room for continued hope narrowing. Cayde's death is Destiny finally committing to consequence.
