Three dwarves risk everything to escape Bighole - the mine-city, in a desperate attempt to regain their freedom and friendship. Long time ago, when the goblin horde was still strong, their raids against the dwarven mine-city of Bighole were regular...and devastating. Many children lost their entire families. Their life was branded by hunger and loneliness. Such hard conditions often give birth to the strongest... and most volatile of friendships. Hunger got Bore, Londie and Nufrie together, but the combination was too destructive. A fire station set on fire... explosions... thievery... assault... a terrible mishap involving a mayor and an egg... The authorities had to intervene, and the boys were separated forever At least... that was the plan. Now, forty years later, Bore Rockhard is guarding the dangerous and windy Seventh Tunnel, recalling the good old days. The goblin horde is long gone, and his life as a guardian is hard and boring. He knows there is more to life than this pointless existence. And so, he decides to track down his childhood buddies and escape in the vast and dangerous place known to the dwarves as The Great Outdoors. But what will be the result of their reunion now, when the boys are all grown up? And what will they find in the endless snow covered woods of The White Mountain, if their daring plan succeeds?
