Netherworld
From Disgaea Wiki
The Netherworld is the location where many of the games in the Nippon Ichi universe take place in. Netherworlds are planets ruled by Demons with the most powerful one being the Overlord. Netherworlds are known for being dark places where evil deeds such as Murder, Excessive Violence, Unwanted Destruction, Theft and other things that are considered crimes by humans are considered daily activities. Demons run a muck throughout these worlds, basically doing whatever the heck they want. Just as there are many different planets, there are many different Netherworlds as well. Powerful demons are also known for conquering human worlds and turning them into Netherworlds.
[edit] History
In La Pucille Tactics, a demon hunter named Priere battle with demons that where escaping from a nearby Netherworld into her world. However, when she went to fight them on their own turf, they began to respect her and called her a Demon Lord as well as submitting themselves to her. Eventually Priere became corrupt by the Netherworld and turned into a Demon herself and soon became that Netherworld's Overlord. This Netherworld is interesting because the land and even the sky appear distorted and swirly like a bizarre water effect.
Later, in Disgaea: Hour of Darkness, another Netherworld was revealed. This Netherworld was one that would be ruled by the soon to be Overlord Laharl. This Netherworld was much more detailed than the last as this one had buildings and an actual environment with the most well known land mark being the Overlord's Castle. This Netherworld however was known for having large amounts of Volcanic and Frozen areas. While there is some forests, they are few and far between. This Netherworld is also the one closest to the Planet Earth. Priere's Netherworld also appeared in this game although it was slightly altered.
In the game Phantom Brave, no Netherworlds were shown but a small island named the Island Of Evil was similar in appearance to a Netherworld and was infested with Demons. The game's main villain, a demon named Sulphur, was attempting to conquer into the game's main setting of Ivoire and turn it into a Netherworld so it is possible the Island Of Evil was the first place he infected.
In the game Makai Kingdom it is revealed that there is actually nearly thousands of Netherworlds out there. It is also revealed that Overlords are aware of the other Netherworlds and tends to fight with Other Overlords over the Netherworlds to expand their territory. We also see a wide variety of Netherworld terrain throughout the game.
In Disgaea 2: Cursed Memories we see that if a Demon is powerful enough, he or she can turn a peaceful human world such as the Country planet of Veldime into a Netherworld and the inhabitants into demons. This means that there MAY have only been 1 Netherworld to start with and all the others are planets that were conquered by demons and turned into Netherworlds.
In Disgaea 2: Dark Hero Days it is revealed that Axel the Dark Hero lives in a whole other netherworld. This netherworld seems a little more urban then the other ones. It even has Japanese Style houses and Concrete Roads, making it seem more like Tokyo than a Netherworld.
In Disgaea 3: Absence of Justice the Netherworld shown is one that is main the Nether Institute Evil Academy. Because the Academy expands so often, it's hard to tell what parts of the Netherworld is part of Evil Academy and what parts are still free ground. It wouldn't be crazy to think that everyone in this Netherworld actually lives on campus. The campus also extremely bizarre due to the fact that one section is a frozen wasteland and another section is similar to an active volcano.
