The Mearas are a race of highly intelligent wild horses which originate from Rohan. They were originally descended from the horses of the Valar Orome, which he brought to Middle-earth during the Wars of Wrath in the First Age. The founder of Rohan, Eorl the Young, tamed the lord of the Mearas of Rohan. Since then, the Mearas only bore the Kings of Rohan and their families.
