Celebrimbor slain by Sauron in Eregion
Event Type: Genealogical
Age: 2nd Age - Rings
"At last the attackers broke into Eregion with ruin and devastation, and captured the chief object of Sauron's assault, the House of the Mírdain, where were their smithies and their treasures. Celebrimbor, desperate, himself withstood Sauron on the steps of the great door of the Mírdain; but he was grappled and taken captive, and the house was ransacked. There Sauron took the Nine Rings and the other lesser works of the Mírdain, but the Seven and the Three he could not find. Then Celebrimbor was put to torment, and Sauron learned from him where the Seven were bestowed. This Celebrimbor revealed, because neither the Seven nor the Nine did he value as he valued the Three; the Seven and the Nine were made with Sauron's aid, whereas the Three were made by Celebrimbor alone, with a different power and purpose. Concerning the Three Rings Sauron could learn nothing from Celebrimbor; and he had him put to death."
