Shorin

Shorin was an Old God and the first of the dragons, the children of Shorotash, and is known to be the God of Destruction and the Harbinger of the Apocalypse. He is the nemesis of Eternity and is destined to one day devour all of reality and return to form as the One Being. He is nicknamed the Realm-Eater and feasts on the souls of all that is dead, trapped or tainted. He was betrayed by his brother, Gwynblleiddovah, at the end of the First Age and is believed to have been imprisoned by Calenkyad and the Three Tongues beneath Tir Triften, where he waits dormant for Armageddon.
