Twilight Town from KH2
Twilight Town was briefly introduced in Kingdom Hearts: Chain of Memories, in which Sora explored the memories of the other side of his heart. By Kingdom Hearts II, it is a major part in the story where Hayner, Pence, and Olette reside. DiZ created a simulation of the town and its people to keep Roxas in a false sense of security and away from Organization XIII until Sora's restoration was complete. Roxas is playable only in this world.
Twilight Town is split into two parts, the shopping district and the residential district, with a train that connects the two. There is also a huge clock tower in the middle of the town that is part of a train station. This gigantic station is on top of a hill that overlooks the shopping district. The trains from here head to the ocean as well as the Sunset residential district. The clock tower is seen as the symbol of Twilight Town and is loved by its citizens. Toward the end of summer vacation, the station sets up a campaign of free use of the trains, so the station becomes filled with children.
Following on, in Twilight Town the player is introduced to the second playable character of Kingdom Hearts II, Roxas. He hangs out with the rest of his friends in a little place near the shopping district. At this place we can see sunlight coming in from the cracks. Originally, it seems to have been a passageway, but is now a hideout for Hayner and his friends, Olette and Pence. They've brought a lot of stuff into this place. From the cracks in the ceiling, you can see part of the train tracks, and sometimes you can hear the train as it passes by.
In the middle of the shopping district, there is a large Tram Plaza. There are plenty of stores here, including an accessory shop, as well as lots of houses lined up. The tram that travels through the plaza is a very important vehicle, and the citizens use it often. Around the suburbs of the town is Sunset Residential District. This place overlooks the ocean. Streetlamps line a small river that passes through the middle of the district, and not too many people are seen walking around. This area has Sunset Station, where the train from Central Station takes you, and Sunset Hill, where you can seen the most beautiful sunset in town. The monument on top of the hill is a tribute to the building of the clock tower.
Within the world of Twilight Town is also the Tower, the residence of Yen Sid and Flora, Fauna, and Merryweather. The Tower is located on something of an island in space, and is only reachable through a special train, colored blue with golden stars and adorned with a large wizard's hat. Yen Sid explains the Heartless, Nobodies and Organization XIII in detail to Sora, Donald and Goofy here. Flora, Fauna, and Merryweather, also create Sora's new outfit, granting him the power of Drive. Maleficent is revived here, and Pete is also met for the first time.
Roxas and Hayner later enter a late summer tournament at the Sandlot of Twilight Town called "the Struggle" in which he must face off against several others. The battles are one-on-one, and the basic premise is to pick up little orbs that the opponent drops. The popularity of the event is enormous. Other competitors taking part include Seifer Almasy, who is with Raijin and Fujin from Final Fantasy VIII, Setzer Gabbiani from Final Fantasy VI and Vivi Orunitia from Final Fantasy IX. Also lurking around at the time of the competition is Axel, who briefly fights with Roxas.
On the outskirts of the town is a mysterious large mansion. Going from the Tram Plaza, the player has to pass through a forest to get here. The gate is locked, and it seems impossible to enter or leave, but there are rumors of 2 shadows being seen in the second floor windows. DiZ transported Sora, Donald Duck and Goofy who were in the process of restoring the memories lost before the events of Castle Oblivion to the basement of the mansion to speed up the process for his revenge against Organization XIII. It is revealed later in the game that the portal to the final world of the game, the World That Never Was, was actually hidden under the basement of this mansion in the Twllight Town simulation. Twilight Town has plenty of jobs to offer Roxas and Sora, including mini-games that feature delivering letters on a skateboard, in addition to placing posters.
