Thráin I (Third Age 1934 – 2190, aged 256 years) was the son of Náin I and King of Durin's folk for 209 years, from 1981 to 2190. His father was slain by a Balrog and the Dwarves of Khazad-dûm driven from their home. Thráin led a portion of his people east to Lonely Mountain, were he became the first King under the Mountain. Among the riches he found there was the fabled Arkenstone. He was succeeded by his son Thorin I.
