One of the most beautiful sights in all of Beleriand, the pools were beloved by Finduilas of Nargothrond, who was given the nickname Falivrin after the Sun on the Pools of Ivrin by Gwindor.
The river Narog began here. Túrin Turambar was healed from his daze after killing Beleg at the site by Gwindor. Glaurung came by it on his way to Nargothrond, and defiled them. Túrin, passing north to his old home, found them ruined.
EithelIvrin was the springs that fed a lakeland at the feet of the Ered Wethrin, the Mountains of Shadow on the northern borders of Beleriand.
It was here that Gwindor brought Túrin after he had mistakenly slain his friend Beleg, and the pure waters of Ivrin healed him of the madness of his grief.
When Glaurung the Dragon passed by the Pools of Ivrin on his journey to attack Nargothrond, he destroyed their crystal purity forever.
The spring that gave rise to the River Narog was EithelIvrin, and the waterfalls and lakes of this region were known as the Falls of Ivrin and the Pools of Ivrin, respectively.
The pools that lay in the southern Ered Wethrin, and formed the source of the River Narog.
