The dark twist is that it's still just as inimical to humans as a typical Mordor. The Sea of Corruption note (Japanese: 腐海 - fukai) from Nausicaä of the Valley of the Wind is depicted as this at first, but is later revealed to be the Ghibli Hills. Of course, it all has symbolic ties to his own origin. Seeing his hideout, which already looks like this, disgusts Lucia and makes her wonder what would possess anyone to like that. Michel in Mermaid Melody Pichi Pichi Pitch wants to turn the world into a rather odd-looking Mordor: rocks jutting above the clouds, giant neon DNA strands shooting out of the sky, and wings on every animal. There is no life outside of the castle maintained largely by Clef - even the monsters are gone. In the second season of Magic Knight Rayearth, Cephiro is Mordor because it lost the mystical ruler who had sustained the land. Kimba the White Lion has Dead River, a mountainous and desert-like valley that serves as Claw's lair. In Inuyasha, Naraku has a mobile Mordor a magically generated cloud of poisonous gas that follows him to wherever he chooses to abide. Hellsing has London after it was invaded and destroyed by the Millennium. Bleach has Hueco Mundo (Hollow World in Spanish), the place where the Hollows reside. Should the Big Bad be defeated and the good king restored, often the skies will clear up and the birds and bees and flowers will return at warp speed. Often, this land was once a beautiful place before the Big Bad got hold of it, and it's presented as a stark example of what could happen to the hero's world should he or she fail in stopping the Big Bad. In a Fantasy Setting, Mordor is often this way because the evil of the Big Bad who rules the place radiates throughout the land, or because his Black Magic acts as a Curse on it. It may even be an Eldritch Location, defying the laws of nature (and most Eldritch Locations are Mordor). May contain the ruins that show that once people had lived here. Expect frequent volcanoes and/or ice storms. Poisonous marshes and swampland are also quite common. What little vegetation there is (if any) will be withered and rotting or mutated into an "evil" variety that's covered in sharp thorns and/or liable to eat people.
The sun is always hidden behind endless dark storm clouds. Mordor is a black and bleak type of shadowland.
