Generate only the exterior entrance...

Generate only the exterior entrance to Erebor (the Lonely Mountain) in Minecraft, about 48 blocks wide and 70 blocks deep. Create a grand dwarven mountain gate with massive stone doors, carved dwarven motifs, huge stone pillars, torches or braziers, and epic dwarven decorations. Do not include interior halls or rooms—focus only on the entrance, the staircase, and the surrounding mountain façade. Make it monumental, dramatic, and dwarven in style.
