The dragon looked at Anthony with seriousness as he continued his tale: "I told you that for a dryad to be born, it needs a strong essence of life, but it wasn't always so difficult. In the past, dryads existed in great numbers, coexisting with the Nature Elves and the Earth Elves. The three races lived around a great tree, unique in this world. It was very tall and large, occupying about 500 kilometers of land just for the trunk. Its leaves were beautiful, crystals of dark or light green, and its trunk was brown with large veins through which flowed the essence of life. It was a world tree, unique of its kind."
