Eldarion was the first and only son of Arwen and Elessar. In the year 120 of the Fourth Age Eldarion was given the tokens of kingship by his father, who then willingly gave up his own life so that his son could become the second King of the Reunited Kingdom. A hundred-and-five years after the fall of the Dark Tower, the king encountered a renewal of Morgoth-worship during his reign. Eldarion stopped his people from turning to evil practices. He afterwards ruled peacefully for an unspecified amount of time well into the Fourth Age of Men. Little else is known of king Eldarion and his reign, save that he left heirs to continue the House of Telcontar after him.
