The Rise of Rivendell
With Celebrimbor’s death, Ost-in-Edhil fell to Sauron’s forces, and the host commanded by Elrond found itself in similarly dire straights. Attempting to both try and stem the tide of the armies laying waste to what was left of Eregion, as well as safeguard the passage of survivors away from the carnage, Elrond found himself saved from his armies’ total destruction by the timely arrival of the new forces from Khazad-dûm and Lórien. The Dwarven and Elven hosts brought Elrond’s forces time to escape with the survivors of Eregion before they themselves were pushed back into Khazad-dûm, and eventually back through the mountain passes into Lórien.
But instead of retreating to Lindon and Gil-Galad, Elrond took his remaining forces and the Elves that had escaped Eregion’s fall to the eastern edge of Eriador, where they founded Imladris, better known as Rivendell. What was initially an outpost quickly grew into a new bastion for the Elves, a stronghold where Elves could find a new home away from Sauron’s slaughter.
