Hearing the Elf City Lord's story, Lorne roughly understood the truth.
It turned out that the elves did not think that they were high and mighty and did not want to communicate with other races. Instead, after saving the Ancient Tree of Life, it made a prophecy and said that it needed to transform ten thousand years later. It also let the elves plan for this matter.

In the beginning, it was to find powerful adventurers and let them help the elves find the special materials they needed.
However, because it had been too long, and the matter regarding the Hero was hidden by the higher-ups, the elves later became more and more arrogant, even looking down on any race.
In the end, this happened.
