Fastred was born in T.A. 2858, the twin brother of Folcred and a son of King Folcwine of Rohan. During Gondor's struggle against the Haradrim in T.A. 2885, Fastred and Folcred rode south to Ithilien at the head of an army of Rohirrim. They joined with the gondorian force commanded by Turin II and led the cavalry charge that broke the Haradron invaders at the decisive Battle of the Crossings of Poros. Unfortunately, both Fastred and Folcred died in the attack, stunning their noble father (who had been dissuaded from going on expedition). Their grateful Gondorian allies paid a huge headprice to the Riddermark and gave the two Warriors a heroes' burial in the tomb-mounds of Haudh-in-Gwanur that were erected by the ford.
