Araphor was the son of King Arveleg I of Arthedain.
He came to the throne in 1409 at the death of his father by the hands of evil men of Rhudaur and Angmar.
Not yet full-grown, Araphor nevertheless managed to drive back the assault from Fornost and the North Downs, with the help of Círdan of Lindon.
Dúnedain refugees from Cardolan and Rhudaur held out in the Barrow-downs, or in the Old Forest behind.
During these wars many Stoors (Hobbits) fled from Eriador and returned to Wilderland, and became the river people of Sméagol and Déagol.
Araphor was succeeded at his death in 1589 by his son Argeleb II.
