In the west of the Westfold, near the Gap of Rohan, stood the magnificent peaks of the Thrihyrne (S."Neledhras"), a triple horn which formed the highest massif in the White Mountains. Jet-black where it was not shrouded by eternal snow, the Thrihyrne dwarfed its neighbors and anchored the southern side of the Gap. Beneath it, to the east, lay Deeping-coomb, the mouth of a gorge which cut into the northwestern White Mountains below the great peak, the stalwart citadel of the Hornburg. A maze of underground passages connected it to the glittering fastness of the Aglarond.
