Hyarmentir

Hyarmentir was a mighty mountain to the south and east of Valinor - one of the tallest in Aman (though Taniquetil, to the north, was taller still). From its peak, Melkor and Ungoliant looked out over the Tree-lit land of the Valar, before they descended Hyarmentir's long, shallow western slopes and set out to destroy the light of the Two Trees.
