He got back on his hooves and struggled on. A tunnel somewhere off to the right of him collapsed, and the echoing monstrous noise of the drilling machine could be heard echoing through the walls, terrible and as inevitable as the promise that night followed day. Picking up the pace, he found another pony, Heart Fire, who waved him over. “Come on!” he shouted. “Happy Hour found the gate!” Warm Night didn't respond, merely running after his friend. He saw light up ahead, finding the entire herd of prisoner ponies crushed up against the iron bars the dogs had installed to prevent escape. The gates didn’t even have locks or hinges. Instead, it was closed by a mechanism that hid behind rock. The gates would rise into the ceiling to let passage through. Warm Night’s mind raced. The unicorns of the group were trying to force the gate to lift as the earth ponies bucked and thrashed against its unyielding steel. Pegasi pawed at the ceiling desperately, trying to break the rock to get at the mechanism that would free them.
