During his reign, in circa 1150, more Hobbits entered Eriador and the lands of Arnor from Wilderland. Most of these were Fallohides and Stoors (who came over the Redhorn Pass and settled mainly in Dunland and the Angle), joining the Harfoots who had come earlier during the time of Celepharn's father Mallor.
Celepharn ruled Arthedain for eighty-one years, and was succeeded by his son, Celebrindor, upon his death in 1191.
