The main reason why it was called a myth was that the things the other two elven royalty possessed were too incredible.
Of the three great elves, the Wood Elves represented life. There was nothing wrong with this. Elves were very coincidental crystals of life at the beginning of many worlds, using their vigorous vitality to attract powerful creatures to coexist and grow together was the beginning of most elves. Even though the saying that the wood elves could represent the entire life system of the physical plane was exaggerated by many scholars.., but there was still some explanation.
The other two were more ridiculous.
Among them, the Elf Elves represented space-time. It was rumored that after the royal family developed, the elves of this race could freely travel through space-time and control the space-time channel of the universe!
