Tinion was a Silvan elf who was a Sentinel of Lothlorien. He becomes the new Lord of Lothlórien after Celeborn ventured west to the Undying Lands. He is the husband of Uruviel, the father of Ernoviel, and the grandfather of an unnamed grandson.
A descendant of the Nandor, Tinion was born in the realm of Lothlorien in the year 1981 3A when Celeborn and Galadriel returned and became the Lord and Lady of Lothlórien. While growing up, he dwelled on a flat in Caras Galadhon, the City of the Trees, where he became very loyal to Lord Celeborn. Celeborn considered him as a son and saw in a vision that he would one day become the new Lord of Lothlórien after he departs to the Undying Lands. In 2509 3A, Tinion married Uruviel, a loyal maiden to Lady Galadriel. Together, the two gave birth to a daughter and named her Ernoviel.
Over the years, Tinion mentored his daughter on how to become a skilled warrior and protector of the woods. In 2941 3A, Tinion and his wife attended their daughter's wedding when Ernoviel married her unnamed husband, and would later give birth to an unnamed son.
War of the RingEdit
During the War of the Ring, Tinion and his daughter were the ones who welcomed Elladan and Elrohir, the sons of Elrond, who had come to bring a message to Celeborn and Galadriel of the Fellowship's quest to destroy the One Ring. He was present when the Fellowship of the Ring arrived to Caras Galadhon to meet with Celeborn and Galadriel. After the Fellowship was offered shelter, Tinion and Uruviel were among the elves that promised to help the Fellowship in any way they could.
After the war ended, resulting in the death of Sauron; the One Ring was destroyed by Frodo Baggins. Tinion and his family accompanied Celeborn and Galadriel to the great city of Minas Tirith and attended the coronation where Aragorn, son of Arathorn, becomes the High King of Gondor and Arnor on Midyear's Day. They later accompanied Celeborn and Galadriel where they travelled to Rohan and attended the funeral of King Theoden. On the way home, they met with Treebeard at Isengard, the place where Saruman met his end.
After Celeborn and Galadriel left Middle-earth to return to the Undying Lands in 10 4A, Tinion and Uruviel remained in Lothlórien and became the new Lord and Lady of Lothlórien during the early years of the Fourth Age of Middle-earth.
