Ost-in-Edhil was the capital city of the Elven realm of Eregion in the Second Age.


Ost-in-Edhil, by Alan Lee

Ost-in-Edhil as depicted by Alan Lee

Ost-in-Edhil was established by the Ñoldor in SA 750, located where the river Sirannon met the Glanduin. The Elven-way was eventually constructed to the West-gate of Khazad-dûm under the shadow of the Misty Mountains, to facilitate communication and trade between the Dwarves and the Elves.

The city was ruled by Celebrimbor, founder and leader of the Gwaith-i-Mírdain and grandson of Fëanor. Here the Ñoldor created the Rings of Power with knowledge given to them by Sauron, posing as Annatar, "Giver of Gifts". When Celebrimbor discovered Sauron's plan to ensnare them, he hid the rings and did not use them ever again, refusing Sauron's demand to surrender all the others. This incited the War of the Elves and Sauron, in which Ost-in-Edhil was soon completely destroyed by Sauron's forces. Its ruins survived into the Third Age.[1][2]

Three millennia later, the Fellowship of the Ring encountered the ruins of Ost-in-Edhil shortly before reaching Moria, and Legolas "heard" the stones speaking of the Elves of Eregion:

"Deep they delved us,

High they built us,

Fair they wrought us,

But they are gone."[2]


Ost-in-Edhil is Sindarin, meaning 'Fortress of the Elves'.

The city as seen in the finale of Season One

Ost-in-Edhil appears in The Lord of the Rings: The Rings of Power as the home of Celebrimbor, though it is not referred to by name. After Elrond negotiates an agreement with Durin III of Khazad-dûm, the dwarves come and assist in building a new forge for the Elven-smith. Later, Sauron in the guise of "Halbrand" gains Celebrimbor's trust and gives him counsel, which leads to the forging of the Three Rings.

The Lord of the Rings Online - Ost-in-Edhil

"Caras Gelebren" before its fall in The Lord of the Rings Online

The Lord of the Rings Online, lacking rights to material in which the name Ost-in-Edhil is used, interprets it as twin cities as "Mirobel, the Jewel-town" and "Caras Gelebren, the Silver Bastion".
