Celepharn was the son of King Celepharn of Arthedain.

He came to the throne in 1191 at the death of his father.

Celebrindor's rule over Arthedain was a peaceful and uneventful one, as relations with the other splinter-realms of Arnor, Cardolan and Rhudaur, were good, and no evil threathened the realm yet.

Celebrindor died in 1272 T.A. and was succeeded by his son Malvegil.
