World Terminus

The World Terminus is a location from Kingdom Hearts.

Found deep within the End of the World, the World Terminus is a series of pillar-like structures spread over what appears to be a vast empty space. Upon each pillar is a beam of light that acts as a terminal to an area within one of the worlds Sora has previously visited. Also on each pillar is a sphere of light enabling travel to the previous pillar and to the next pillar, the latter appearing only after one has entered the terminal.

The final pillar bears what appears to be a pillar of flame in place of a terminal, though this, in fact, leads to a previously-inaccessible chamber in what is presumably Hollow Bastion, which appears to be a laboratory of some sort. The pillar of flame will disappear following Sora's departure therefrom, leaving behind a hole leading to Bald Mountain and the boss battle against Chernabog.

The Terminals
At first, every terminal is a blue color. If you have sealed that world, it is a purple color, meaning that only Atlantica, Olympus Colosseum and Halloween Town may possibly be blue, and at least one of former two must be sealed in order to reach Hollow Bastion. The only exception is the last terminal, which is always green.

Each terminal takes Sora and his party to a location from each world, meaning that Monstro, being a giant whale instead of an actual world, is not accessible from the Terminus. The first pillar takes Sora to the Third District of Traverse Town, where he must battle more powerful versions of Heartless there, afterwords, receiving the Brave Warrior item (originally obtained by defeating the Guard Armor) and the door to the First District is unlocked, allowing Sora to return to the World Terminus.

This same pattern follows for all other terminals, with the exception of the green terminal, leading to the Hundred Acre Wood and the final terminal, leading to what is presumably Hollow Bastion. In order, Sora is taken to Traverse Town, Wonderland, the Olympus Coliseum, Deep Jungle, Agrabah, Atlantica, Halloween Town, Neverland, Hollow Bastion, and the Hundred Acre Wood. In Atlantica and Halloween Town, Sora is changed into his merman and vampire forms, respectively, to reflect his entry into the same. Upon completing each terminal, Sora receives a copy of whatever item he received upon beating the boss of said world.

The green terminal, which takes Sora to the Hundred Acre Wood, bears a save point rather than a host of enemies, though when one uses it, one is noted as saving the game in the World Terminus rather than the Hundred Acre Wood. One will also find there one or two items, and it is interesting to note that the colour of the light that forms the terminal to this world is green rather than blue or violet.

Upon entering the final terminal for the first time, Sora is brought to an unidentified location within what is presumably Hollow Bastion upon stepping through an orange terminal that greatly resembles a pillar of flames, this presumably being the place in which Ansem performed his first experiments, before being transported to Bald Mountain. On all other occasions, Sora is transported directly to Bald Mountain, and the orange terminal will have become a hole in the floor.
