In the Ettenmoors in Eriador there lived an evil race of Hillmen who served the Witch-king of Angmar in the Third Age of the Sun. These barbarian Hillmen were fierce and numerous and they were allied with the Orkish legions. In the fourteenth and fifteenths centuries they subdued the provinces of Rhudaur and Cardolan of the Dúnedain of the North Kingdom. In 1974, after six centuries of intermittent war this alliance finally brought down Arthedain, the last of the proud Dúnedain provinces of the North.
But this too was the time of the Hillmen’s own ruin. Hardly had the Hillmen and their Witch-king taken Fornost, the last citadel of the Dúnedain, when they were attacked by a great army led by Eärnur of the South Kingdom of Gondor, Círdan of Lindon and Glorfindel of Rivendell. In this Battle of Fornost the power of the HIllmen was broken, the Orcs exterminated and the kingdom of Angmar was destroyed. The Hillmen became a hunted scattered people.
