Spiral Mountain

While the eight DigiDestined where in the Real World fighting, 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. When a Dark Master is defeated, his territory will also disappear along with the Dark Master, as seen with MetalSeadramon, when he died, the Ocean part of Spiral Mountain disappear from it and resembles itself back to form the "old" Digital World. After the Dark Masters were defeated, the mountain was destroyed by.

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 lagoon. Whamon sacrificed his life to protect the children and then was able to kill MetalSeadramon with his Great Tornado attack. After this the ocean spiral disappeared from the mountain (but was however, still seen on the mountain during Puppetmon's part of the Arc)

Digital Forest
The forest section is controlled by 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. The forest is mostly made up of locations from the digital world that had lots of plant life around, including Digitamamon's resturant; it is there Etemon made his failed come back. Later destroyed Puppetmon when he failed to try controling him. After Puppetmon met his doom the forest spiral disappeared from the mountain, causing the digital world to appear dark and colorless.

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. . 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.

Digital Wasteland
The wasteland is ruled by Piedmon from his castle on top of the mountain; it is both a spiral and the land on top the mountain. However, the land on top the mountain remains even if the spiral vanishes; it was a natrual wasteland before. The wasteland features any other Digital World scenery the other Dark Masters didn't take for themselves, turned black and lifeless; most likely this would help his soldiers find his enemies do to thier colors. The caves of this wasteland feed upon the insecurities of those who enter, trapping them in illusions; only through a realization and sheer will power can someone break free of the illusion. Primary Village was located in this section of the mountain, desolated with no chance of new 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 's Gate of Destiny. After Piedmon's demise the wasteland spiral disappeared from the mountain.

Trivia

 * After Metalseadramon and Puppetmon were defeated, the sky around spiral mountain became dark and colorless- perhaps meaning that without the vegetation or sea on the mountain, the area around it changes to reflect the two remaining Dark Master's territories.
 * The spirals are not properly aligned on the mountain; Piedmon's territory is hardly visible, making Machinedramon's territory be easily mistaken for it.
