Formless World

The Formless World (Japanese: 形のない領域 Formless Realm) is the second alternate dimension located exclusively within the Xeno region that appears during the events of Pokémon Aether, Nether, and Tether Versions. A counterpart to the Desire World, the Formless World can only be accessed by one who possesses the two Dharmic Keys through a currently unknown method. This is the realm in which the consciousness of the twin Legendary Pokémon Naraka and Savara were sealed following their rampage and defeat at the hands of ancient Pokémon Trainers and Vinipatika. The world itself is nothing like any yet seen, as it appears to have no physical aspect in the slightest, consisting of only massive tracks of multi-colored mist that can be walked on in any direction that the walker desires. It is through this that the one who desires to awaken the Legendary Pokémon must traverse before accomplishing their goal, and depending on which of the Dharmic Keys they hold, they must travel through two alternating routes, each one leading to the consciousness of one of the Legendary Pokémon. Each of the two routes are made up of two 'chambers', each with a specific kind of mist that tests and challenges the traveller, tasking them to give "form to the formless" by solving the puzzle there and creating a clear path to the sealed Pokémon they seek. The realm is the ultimate end-goal location of Team Samsara, due to it being the place where they can truly realize their plans and ambitions leading to that point.

As with the Desire World, it plays a major part in Pokémon ANT.

Trivia

 * The Formless World is directly inspired by the mysterious Formless Realm from Buddhist cosmology, and its name in Japanese even translates into "Formless Realm". Along with the Desire World, it has been heavily modified in order to fit the  Pokémon world, the most notable being the retooling of the three 'spheres' that make up the Formless Realm being turned various "chambers", and most of the Formless World's geography is distinct from the Formless realm, and its function is completely seperate as well (with the original Realm being a place where devas who have achieved and remained within the " Four Formless Absorptions" are allowed to reside thanks to the good karma from that accomplishment). The idea of its gameplay being based heavily around puzzles was an idea that was given by Yumoz.
 * It was originally supposed to have the same function as the Desire World, and vice-versa, but the author felt that it would be more logical to seperate them into two worlds, as it would make the ressurection of Savara and Naraka much more difficult, the goal of the Dharmic Keys' creators in the first place.
