Orodreth was the second of the four sons of Finarfin* and the father of Finduilas; he was also the second and last King of Nargothrond. During the First Age, he came with his brothers and sister to Middle-earth in exile and fought in many of the early battles against Morgoth. Initially, Orodreth was a warden of Finrod in the tower of Tol Sirion, but when it was captured by Sauron in the Dagor Bragollach, Orodreth fled to Nargothrond with Finrod, whom he later succeeded as King. He was killed in the Battle of Tumhalad, and his daughter Finduilas was captured and slain soon after.
* In the published version of The Silmarillion, Orodreth appears as Finarfin’s son; in later writings, however, he is the son of Angrod and the grandson of Finarfin.
