The longer Risen session — the seasonal story progressing through the alliance with Caiatl, the shared objectives that the Guardian and the Cabal Empress are pursuing despite their history. The fireteam as family is the season's emotional argument: the people you run activities with, the names in the roster, the coordination that happens without planning because you have learned each other's rhythms. Destiny's social layer is built around this — the clan system, the Guided Games, the fireteam that becomes more than a tactical unit. The season names it directly.
