Key to the Ancient Land of Treasures

Dimensional access keyAuctioned; later individual custody is not identified

The Key to the Ancient Land of Treasures is an ancient access relic associated with the hidden region where the hero Libros was said to have obtained the Demon Slayer Sword.

History

The Arcadia auction

Gresham Bel'or presents the glimmering key inside a hexagonal box as the auction's final lot. Rather than keeping it, he emphasizes that activation requires an astronomical quantity of energy, making possession alone insufficient. The sale exposes the rediscovered Ancient Land to Arcadia's great clans and contributes to the guarded expedition for which Leon later distributes entry emblems. The corpus does not identify a single later holder after the auction. (Chapters 28 and 36–37)
