Legends are that dwarfs created a giant fortress underground. The topside entrance was made of obsidian and the grand hall of diamond, gold and emerald. All that is created is the hall and a bit of a sleeping chambers. Create mines and other structures as you explore the depths of the unknown underground. Creepers and other mobs will try and halt your progress but don't let them. Enjoy. I created the game around the idea of Dwarfs!?
