Wooden walls, Warg-guardians, and a war-host from Angmar rest at the foot of Mount Gram. From here, the great Uruk War-tyrant Akúlhun commands the forces of Angmar. The fortress is well-guarded and nearly impenetrable. From this base of power, War-leaders launch their assaults against the Free Peoples and seek to drive them from the land to make ready their war-machines for an invasion of lower Eriador.
