"The island of Númenor was shaped like a 5-pointed star with each peninsular promontory having its own unique geological and physical features and names: Forostar, Andustar, Hyarnustar, Hyarrostar and Orrostar.
Forostar was the northern promontory of Númenor, a land of rocks, cliffs and high moors with woods of fir and larch. It stretched some two hundred miles from its southern borders with the Mittalmar to its North Cape. The great road from Rómenna to Andúnië passed through its southern parts, at Ondosto.
The lands farther north, toward the Cape, became rockier and more mountainous. In the far north was a region around the peak of Sorontil, where the landscape fell sheer into the sea forming tremendous cliffs. This was the abode of Eagles, and also the dwelling-place of Meneldur Elentirmo, heir to Númenor's throne and a watcher of the stars, who built a great castle tower here to follow the movements of the heavens."
