Arvegil was the son of King Argeleb II of Arthedain.

He came to the throne in 1670 at the death of his father.

During his rule many Hobbits living in Arnor settled The Shire, which had been granted to their people during the time of Arvegil's father. Arvegil's rule was rather uneventful, as not just the Dúnedain had suffered under the Great Plague, but their enemies as well. Still the borders were not watched as good as before, and evil continued to creep in from Angmar.

Arvegil died in 1743 T.A. and was succeeded by his son Arveleg II.
