True to his word, Talos found a dungeon as per Arnold's specifications. It was a dungeon located inside the volcano on Jeju island which now belonged to the United Korean Empire. Thankfully, Arnold had good relations with the new Korean government, ever since he helped them dethrone the bloodthirsty dictator and unify both countries once again.
Although he didn't have any treaties with Korea as he did with Japan, Russia and India. Korea was still much more accommodating to Arnold's needs than any of those countries had been. As soon as the Korean foreign minister was informed that Arnold was interested in buying the rights to a dungeon, Seomun offered the dungeon to Arnold without taking any fees. Even though Arnold wanted to pay them for it.
