> The Silmarillion
Thus the sons of Fëanor under Maedhros were the lords of East Beleriand, but their people were in that time mostly in the north of the land, and southward they rode only to hunt in the greenwoods. But there Amrod and Amras had their abode, and they came seldom northward...
Amras was the youngest of the Sons of Fëanor along with his twin brother Amrod. He also swore the Oath. He lived with Amrod in East Beleriand where they kept to themselves. They felt closer to their brother Maedhros, the leader and oldest of the Sons, than any of the others and were seen at his side during battle. He was killed with his brother in an attempt to forcefully gain the Silmaril in the possession of Elwing at the Havens of Sirion.
Amras and Amrod were alike in appearance and temperment, being twin brothers. They had red hair, an almost shy demeanor, and were renowned as hunters, though not as much as Celegorm.
