Argeleb II was the tenth King of Arthedain and a
was King, the plague came into Eriador from the Southeast.
Cardolan was depopulated heavily, and the hobbits and all other people
suffered greatly. The plague weakened as it came to Arthedain,
and the country therefore wasn't affected as badly as the lands of
and southern Eriador had been.
At this time the Dunedain dwindled in Cardolan, and evil
Angmar entered the deserted graves in which many of the Dunedain's
lords and kings were buried.
Argeleb II was the son of Araphor,
and he was
by his son, Arvegil.
