Spiral Mountain

While the eight DigiDestined where in the Real World fighting Myotismon, the Dark Masters reconfigured the Digital World, transferring most of it (only ruins were left in the "old" Digital World) onto Spiral Mountain (スパイラルマウンテン Supairaru Mauntin). The mountain is divided up into four spirals, each one representing a part of the Digital World and the Dark Master that rules it. At the top of the mountain sits Piedmon's castle among the wasteland. This castle serves as the base of the Dark Masters. After the Dark Masters were defeated, the mountain was destroyed by Apocalymon.



Digital Ocean


The Digital Ocean is ruled by MetalSeadramon and is protected by Scorpiomon and legions of Divermon. It is where the DigiDestined arrive after they were saved by Piximon. The beach where Agumon first digivolved into Greymon is part of this area. After traveling through the ocean with the help of Whamon, the children ended up in a small lake. Whamon sacrificed his life to protect the children and then WarGreymon was able to kill MetalSeadramon with his Great Tornado attack. After this the ocean spiral disappeared from the mountain.

Digital Forest
The forest section is controlled by Puppetmon from his mansion with Kiwimon, Floramon, Deramon and troops of RedVegiemon. The forest floor can be rearranged by Puppetmon's remote control. He also has small voodoo dolls that control the DigiDestined's movements and location throughout the forest. When T.K. was playing with Puppetmon inside his mansion, he was able to destroy the remote and take the dolls. Later MetalGarurumon destroyed Puppetmon. After Puppetmon met his doom the forest spiral disappeared from the mountain.

Digital City
The city is controlled by Machinedramon. It contained prominent features of cities from the Real World such as Saint Peter's Square, the Arc de Triomphe, and the skyline of New York City, all packed close together into one large city. Digitamamon's diner is located on the outskirts of the city, near the forest spiral. Machinedramon uses his army of Mekanorimon and Tankmon to track down the DigiDestined hiding in the city when Kari becomes sick. Impatient, Machinedramon then ordered Operation Elimin-8, in which he gave Gigadramon and Megadramon orders to destroy the the city with the children inside. The children survive their attacks, but are attacked by Machinedramon himself. They manage to survive a deadly fall and wind up underneath the city. Under the city is a system of sewers where WaruMonzaemon forced a group of Numemon to supply power to the city above. Machinedramon was eventually killed by WarGreymon when he sliced Machinedramon into pieces. After this the city spiral disappeared from the mountain.

Wasteland
The wasteland is ruled by Piedmon from his castle on top of the mountain. The wasteland features normal Digital World scenery turned black and lifeless. The caves of this wasteland feed upon the insecurities of those who enter, trapping them in illusions. Primary Village was located in this section of the mountain, desolated with no chance of baby Digimon hatching. The final battle with Piedmon took place at the mountain's peak, where the DigiDestined also faced his bodyguard LadyDevimon and an army of Vilemon. Piedmon was destroyed by MagnaAngemon's Gate of Destiny. After this the wasteland spiral disappeared from the mountain.
