General Information
LocationNorthern Blue Mountains

Mount Rerir was a mountain on the western side of the Ered Luin, in Thargelion (a region of Beleriand) to the north of Lake Helevorn, and it was one of the sources of Gelion.[1]


The land around the mountain belonged to Caranthir, who built a fortress on its western slopes.[2] The fortress was lost during Dagor Bragollach.[3] Elven forces probably withdrew from the area after the battle, and most definitely after Nirnaeth Arnoediad.[4]

After the War of Wrath, Rerir was apparently heavily damaged, and from the Second Age onward it was but only a shadow of its former size.


Rerir is a name in an unknown language, and of an unknown meaning.[5]

Robert Foster proposes the name is Sindarin.[6]


Perhaps J.R.R. Tolkien re-used a name appearing in Norse mythology: in The Legend of Sigurd and Gudrún, Rerir is the name of the grandson of Ódin.[7]
