We discovered a beautiful world, full of green hills and clear streams. This land is inhabited by small, hardworking creatures – ancient goblins who for centuries have been engaged in extracting valuable deposits from the earth. They went deeper and deeper into the ground, the successive layers of the earth were harder, so the shovels became useless. They had to find a solution that would allow them to dig further… They began to blast the rocks with Nitroglycerin. Due to the delicacy of this fluid in a single descent, each goblin could only carry a small portion. When the amount of Nitroglycerin underground was already sufficient, the goblins set fire to the fuse and the stone wall exploded. The blast hollowed out a large cave in the ground, but the dust that filled the corridors leading to the cave prevented them from going down immediately. The underground world hides many treasures, board the narrow-gauge railway leading inside of the Cave of Fortune™ and mine them.
