Barahir lived with 12 companions on the highland of Dorthonion. They were betrayed to Morgoth by a lovesick member of their company. Barahir's son Beren escaped the slaughter and lived to a great destiny.

Earlier, Barahir had fought at the Dagor Bragollach, saving Finrod Felagund's life. For this, he received "Barahir's Ring", which was then handed down the family line.
