During Forthwini's rule his spies learned that the Wainriders, a tribe of Easterlings who had invaded decades earlier, had recovered and were allying themselves with other forces in the East. He alerted King Ondoher of Gondor of the growing threat, and later the Éothéod joined the armies of Gondor in battle against the invaders. Though Ondoher was slain, his successor Eärnil II eventually destroyed the Wainriders. There is no record of Forthwini's fate.
