Spiral Mountain

From Thread 1

According to the anime, Digimon Adventure, Spiral Mountain was the centre of D-World Gamma after being taken over by the Dark Masters. The mountain consisted of four areas (the ocean, the forest, the city, and a dark wasteland) intertwining like a rope, with the Dark Masters' castle at the peak. Metal Seadramon ruled the ocean, Pinocchiomon ruled the forest, Machinedramon ruled the city, and Piemon had control over the dark wasteland. When each Dark Master was defeated, its respective area disappeared from the mountain.
