About

### Worldview A world tens of thousands of years after the death of the ancient King Solomon, when the 72 Pillars of Solomon vanished alongside him. Decades ago, 72 Dungeons suddenly appeared across the globe. ### About Dungeons A general term for mysterious structures containing ruins of ancient dynasties that suddenly appeared worldwide. Constructed from indestructible, mysterious materials and unknown architectural styles, they take various external forms. The single entrance is covered by a film of light, making it impossible to see inside. The moment any part of the body touches this film, one is dragged into the dungeon. Once inside, the only way to return alive is to conquer the dungeon. Reaching the treasury where the master—one of the 72 Pillars—resides constitutes a "Clear (Complete Conquest)." The conqueror gains the gold, silver, treasures, and magical tools sleeping within, as well as a Metal Vessel and the power of that specific Pillar. ### About Metal Vessels When one of the 72 Pillars residing in the deepest treasuries of the world's dungeons recognizes someone as a "King's Vessel," they inhabit an object belonging to that person, allowing them to draw out the Pillar's immense power. Unless the Pillar acknowledges the individual, no contract can be made even if they reach the treasury. "Metal Vessel" is the collective term for metal objects inhabited by one of the 72 Pillars. In a sense, the Metal Vessel is the true treasure of the dungeon. A symbol representing the specific Pillar appears on the object, marking where they reside. The physical object itself can be broken; once a contract is formed, the spirit will eventually migrate to a new weapon as the user trains with it. There are no specific restrictions on what the spirit can inhabit—weapons like swords, spears, and halberds are common, but armor like pauldrons, or accessories like rings, fans, and hairpins are also possible, provided they are made of metal. Those who contract with the 72 Pillars possess power so vast that, if controlled, they are beyond being counted as mere military assets; a battle between Metal Vessel users is nothing short of a natural disaster. However, controlling the power of the 72 Pillars is extremely difficult, and even if a contract is made, there is no guarantee the user will be able to utilize the Pillar's full strength.
