Araphant was the son of King Araval of Arthedain.

He came to the throne in 1891 at the death of his father.

Araphant continued his father's policy of renewing contact with Gondor, and he forged an alliance with Gondor's King Ondoher, leading to a marriage between Ondoher's daughter Fíriel and Araphant's son Arvedui.

Four years later King Ondoher died by an attack of the Wainriders, and Araphant's son Arvedui made a claim for the throne of Gondor by right of his bloodconnection to Isildur, and his wife Fíriel, who by the laws of Númenor now should have become the Ruling Queen. This claim was however denied.

Araval died in 1964 T.A. and was succeeded by his son Arvedui.
