33 Fortress Keys is a main quest in Crimson Desert and the fourth mission of Chapter 11: Truth and Reality, part of the Brave New World sub-chapter. The documents recovered from Strange Manor point to a series of security mechanisms guarding the approach to a massive fortified structure. Before Kliff can proceed, he must locate and activate three "fortress keys" scattered across the Delesyia region. Each key is a mechanical device that, when activated, disables one layer of the fortress's defenses.
