In the world of Middle-earth, there are different types of elves, each with their own unique characteristics and homes. The high elves, or the Eldar, are the most powerful and skilled elves, known for their mastery of magic and crafts. They are believed to have come from the Undying Lands, a faraway paradise, and they reside in the realm of Valinor. The grey elves, or Sindar, are a more ancient and wise elf race, known for their close connection with nature and the forest. They live in the forested regions of Beleriand.
