Digimon World had originally consisted of nine interwoven regions, with the Wind Guardians ruling the skies alone. Later, thanks to Piedmon's plans, the four regions of the Metal Empire, Deep Savers, Nightmare Soldiers, and Jungle Troopers formed the Dark Fourfold Mountain, while the other regions were suppressed in the process.
After Piedmon and the others were defeated, Digimon World, centered on the Dark Fourfold Mountain, lost the protection of its strongest powers. It fell out of balance and slowly began to collapse. Originally, this collapse would have taken a long time, during which the world would gradually have returned to normal. But when Apocalymon appeared, the entire Digimon World was caught in the effects of Apocalymon's ultimate move, Gospel, collapsing completely and beginning its rebirth.
Everything from the old world should have been destroyed in this process. In reality, however, many protective powers existed in this world. When Piedmon built the Dark Fourfold Mountain, for instance, he deliberately avoided them. If the mountain's structure had fully stabilized and brought Digimon World under its control, it would have retained powerful protection even if the Dark Masters disappeared in the future. But thanks to the children's all-out efforts, all the Dark Masters were destroyed. Without their protection, the Dark Fourfold Mountain vanished completely under Digimon World's counterattack.
Apocalymon's ultimate move, Gospel, sent everything in the real world into a realm of fantasy. Apocalymon could then control those powers. Although this move was powerful, it actually had little destructive force. Once spread across the entire world, it was even less capable of shattering those protective powers. However, if Apocalymon had successfully unleashed Genesis, no one within Digimon World, at least, could have resisted. Fortunately, the children succeeded.
In the reborn Digimon World, these places remained protected. Anyone who paid close attention could sense
