まだ人の領域が限られた世界だった神代。
王は地上すべての財宝を集め、
これを納める宝物庫を建造した。

後の世に生まれるであろう様々な宝の原典。
人間の知恵、人間の叡智が確かである証左。
人々はこれを“神の門”と呼び讃えた。
むべなるかな。
これらを納めた「蔵」そのものが、
収納した財宝を上回る神秘となったのだから。

そして。その蔵の鍵は、彼の王にしか扱えない。
鍵の金型は絶え間なく変化し、
財宝の目録は今も増え続ける。
それらを瞬時に読み解く智慧なくして、
宝物庫の鍵は開かない。

In the Age of Gods, where man's domain was still limited, a king gathered all the treasure across all the lands and stored them inside a vault he had built.

Those were known as the origins of all treasures that followed.
The evidence of all mankind's wisdom and knowledge.
People started to praise it as the "Gate of the Gods."
Truly, it is.
Eventually, the "vault" itself became a Mystic more mysterious than the treasures it held.

Also, the key to the vault can only be used by the King.
The key will constantly change its shape, and the vault will constantly store new treasures.
Without the wisdom to instantly understand those Mystics, the key will never be able to open the vault's gate.
