Celebdil

Celebdil: (S. "Silvertine"; Kh. "Zirak-zigil") Southernmost of the three mountains above Moria. Heavily snowbound, it is the "whitest" of the triad. On a ledge near its peak lies Durin's Tower; beneath it descends the Endless Stair which connects the heights, the Dwarven-city, and the Underpassages deep within the earth.
