Nearly an hour on Europa, the Beyond Light expansion's primary location. The Dark Priestess is a Fallen Baroness whose operation on Europa the Vanguard wants disrupted, and the encounter is one of Beyond Light's better pieces of environmental storytelling — the Fallen's relationship to the Darkness mirroring the Guardian's own increasingly complicated relationship to it. Weapons that fire belief are not metaphor in Destiny. They are the literal mechanics of the Darkness subclasses — the Stasis that works because the Guardian believes in its application, the Void that shapes the engagement because someone decided it should.
