Eärendil Azrubêl was one of the most important figures who carries a star across the sky.
Known to be the son of Tuor (Atani) and Idril, Eärendil was raised as a child in Gondolin. When Eärendil was seven years old, he escaped the sacking of Gondolin with his parents, living afterwards in Arvernien by the mouth of Sirion. Eärendil later became the leader of the people who lived there, and married the beautiful Atani woman Elwing. They had two sons, Elrond and Elros.
With the aid of Círdan the Shipwright, Eärendil built a ship and sailed around the seas west of Middle-earth, leaving his wife behind in Arvernien. Hearing of the tragedy that had befallen in Arvernien, Eärendil then sought after Valinor, and he and his wife found their way there at last. Eärendil thus became the first of all mortals to set foot in Valinor. Eärendil then went before the Valar, and asked them for aid for Men and Elves in Middle-earth, to fight against Morgoth; and the Valar accepted his plea.
The Valar, having listened to Eärendil's plea, went with a mighty host to Middle-earth, and overthrew Morgoth, and bound him. Eärendil took part in the battle, riding on Vingilot beside Thorondor and the Great Eagles. It was his blow that slew the great dragon Ancalagon. He and his wife were both slain later during the War of Wrath.
