Glithui

Glithui was a river in the West Beleriand during the Elder Days of Middle-earth.

It was a tributary of the river Taeglin and began in the Ered Wethrin (Mountains of Shadow) near Amon Darthir, which was beneath a dangerous pass that led out of Dor-lómin.

It ran southward for about twenty-five miles where it met the Taeglin.
