Born in the autumn of the year 2084 of the Second Age to a half-Ñoldorin father and a Galadhrim mother in Imladris, he was trained to fight from his adolescence by his father, who had witnessed the fall of Eregion. Early in his life he fell in love with the red and gold of the past-summer forests and the airs and waters of Middle-earth. He also took a liking to wood, as a material, in his youth, and started apprenticing to become a woodworker. Under Gil-galad he marched to Dagorlad and Mordor, where many of his friends and kinsmen, including his father, were slain. After those battles he returned to Rivendell, but his nature got the best of him; Pendaen started his long travels in Middle-earth, walking the forests and plains and riverlands of even the distant East where the stars are strange. 

After almost two thousand years of wandering he returned to the North. Hearing of the war against Angmar, he went to fight with the forces of Arthedain. After the war the North-kingdom was no more, and Pendaen returned to Imladris to be reunited with his old friends. Many were gone. He also learned that his mother had gone to dwell with her kin in Lothlórien, and some time later Pendaen travelled there, staying for a time. He was in Thranduil's court in 2941, and went to Erebor with that host, after which he returned to Rivendell.
