Location: ‘Eriador was of old the name of all the lands between the Misty Mountains and the Blue; in the South it was bounded by the Greyflood and the Glanduin that flows into it above Tharbad.
‘At its greatest Arnor included all Eriador, except the regions beyond the Lune, and the lands east of Greyflood and Loudwater, in which lay Rivendell and Hollin.'

Description: Founded by Elendil after the Downfall of Númenor, it lasted as a single realm until dissension among the sons of Eärendur after his death in III 861 resulted in the division of the realm into three parts: Arthedain, Rhudaur, and Cardolan.
The realm was reunited under King Elessar after the Ring War.
