Frozen Legacy

From publisher blurb: Among the snow-mantled peaks of the Negoiulath Mountains, just above the permanent frost line, stands a field of ice that stretches as far as the eye can see. Once, long ago, a lively and steadfast dwarven kingdom ruled in these mountains, and grew rich in silver. Olaf Stonesinger, a prominent dwarven noble, and those working under him in his mines, profited for years, transporting untold riches into their stronghold high above.
