Spiral Mountain

While the eight DigiDestined where in the Real World fighting, the Dark Masters reconfigured the Digital World, transferring nearly all of it 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 under the control of one of the Dark Masters. At the top of the mountain is the utmost portion of 's wasteland, crowned by his castle, which also serves as a meeting place for the Dark Masters. When a Dark Master is defeated, his territory will disappear alongside them. After the Dark Masters were defeated, the mountain was destroyed by.

After traveling through the ocean with the help of, 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". After this the ocean spiral disappeared from the mountain.

Forest

He also has small voodoo dolls that control the DigiDestined's movements and location throughout the forest; if he moves the voodoo dolls, the victim is teleported to the new location. 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. Later destroyed Puppetmon when he failed to try controling him.

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 and  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.

After this, the city spiral disappeared from the mountain.

Wasteland
The wasteland is ruled by Piedmon; he resides in a castle on the top of the mountain. It's both a spiral and the land atop the mountain. However, the land on top the mountain remains even if the spiral vanishes; it was a natural wasteland before. The scenery is black and lifeless, composed of any areas the other Dark Masters didn't want.

The caves of this wasteland feed upon the insecurities of those who enter, trapping them in illusions, and only through a realization can someone break free of the illusion. Primary Village was located in this section of the mountain, desolated and 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 and an army of Vilemon. Piedmon was destroyed by 's Gate of Destiny.
