Points of Interest

There are 15 Points of Interest in Duomension City:

Name Image Description
Icon Space Anchor Active Perdido Station Waiting Hall Space Anchor Perdido Station Waiting Hall Here, travelers can switch between various lines. Planarcadia's rail transit system is pretty well-developed, placing almost every corner of Ahatopia within your reach.
Icon Space Anchor Active Perdido Station Plaza Space Anchor Perdido Station Plaza Students and office workers rushing to and fro, street artists, talent scouts, part-timers handing out flyers, groups of friends heading their separate ways after dinner... This place is always witnessing small-scale hellos and goodbyes.
Icon Space Anchor Active Yum Yum Alley Space Anchor Yum Yum Alley It used to be called "Gluttony Street," but this place is obviously not a "street," and those who manage the arcadia didn't want to encourage "gluttony" among the masses, so it eventually became what it is now. No matter what they call it now, the food at restaurants in that alley is as good as ever.
Icon Space Anchor Active Nameless Bridge Space Anchor Nameless Bridge All the chaos started with a "Let's Name This Bridge!" voting campaign. Humans wanted to call it "Duomension Bridge," ghosts lobbied for "Afterlife Bridge," ploos pushed for "Ducky Bridge," and students advocated for "Pass-the-Test Bridge"... This unremarkable little bridge nearly sparked total mayhem. To keep things from escalating any further, it remains a nameless little bridge to this day.
Icon Space Anchor Active "@Gate" Space Anchor "@Gate" Ever since this landmark was built, the citizens have loved the name "@Gate." But local software developers hate it, because the "@" symbol constantly crashes their programs.
Icon Space Anchor Active @EntertainmentPlaza Space Anchor @EntertainmentPlaza Officially called the "Duomension City Civic Activity Center Plaza," but locals habitually refer to it as the "@Entertainment Plaza." There was once an operations manager from the "Cosmicon Collective" who tried to register their account name as "Entertainment Plaza" to fraudulently gain followers. They got banned for it later.
Icon Space Anchor Active Perdido Station Railway Platform Space Anchor Perdido Station Railway Platform Perdido Station is Duomension City's intercity transit hub, which naturally makes it the first stop for just about every visitor coming in from outside.
Icon Map Shop BOOK-ON! Shop BOOK-ON! The largest bookstore chain in Planarcadia. It founder once studied abroad on the Xianzhou, and the store's name was inspired by the Xianzhou saying, "Reading is nourishment for the soul."
Icon Map Shop Oiiaiooo Shop Oiiaiooo Pixcoins found in Planarcadia, can be exchanged for goodies with Oiiaiooo~
Icon Map Shop RECORDS Shop RECORDS In the cosmic age, Planarcadia's music fans are still crazy about the most primitive audio receptacle: vinyl records. "RECORDS" is probably the best vinyl record manufacturer in the entire cosmos, because no other civilization bothers with such caveman tech anymore.
Icon Map Shop ∞-Eleven File:Shop ∞-Eleven.png There are at least seventy different versions of the origin story behind "∞-Eleven." This is probably why everyone hates entrepreneurs who used to be History Fictionologists.
Icon Map "Floating Grease Chronicles" World "Floating Grease Chronicles" World Location Context Game System "Floating Grease Chronicles" World Search for imagenate fragments of "Floating Grease Chronicles" and rescue the colorless animals within.
