"But when Eärnur came to the Grey Havens there was joy and great wonder among both Elves and Men. So great in draught and so many were his ships that they could scarcely find harbourage, though both the Harlond and the Forlond also were filled...."
—The Lord of the Rings, Appendix A, Annals of the Kings and Rulers:
The 33rd and last King of Gondor, Earnur, son of Earnil, leads the army of Gondor to the aid of Arnor. He was a great warrior and powerful king, but prideful to a fault. He was easily taunted by the Witch-King of Angmar who had taken residence in Minas Morgul and when he went out alone to defeat him was taken deep within the accursed fortress never to be seen again. He is summoned alongside other Gondorian units when the player uses the Tier 4 Arnor power Army of Gondor.
