Langqiu is a city in the Antares region of the Lunae continent on Mars.[1][2] It is one of the main settings for the Tides of Time Gone By arc of the story.

Description

One of the four districts of ancient Antares city, and it preserves another history of Antares. The haze of "shadows" and the erosion of the "sea" once plunged this land into tumult. Today, under the influence of predecessors, Langqiu maintains a distinctive order.[3]

Langqiu is a Bubble Universe that resides within the Sea of Data—a quantum space[4] that surrounds the fourth planet from the sun of the Solar System, Mars.[5] It is one of the only cities in the Antares region to have survived the Great Eruption, excluding its neighbor, Oxia.[2] However, it was not the Great Eruption that split Langqiu and Oxia apart; rather, it was the Seven Shus who caused the division, placing the Curse of Shadows within the isolated Langqiu.[6]

Before the Great Eruption, Langqiu was one of the biggest cities on Mars,[7] and the people of Langqiu made a living through agriculture.[8] However, after the Great Eruption, only Amber Street was left standing.[7] Rather than through the destroyed agriculture, people came to survive off of an equivalent exchange known as 'Fear Gathering'[9][10]—an occurrence that includes doing business with the shadows,[11] where people can obtain supplies such as food.[12]

Amber Street Great Panic

The Amber Street Great Panic was a calamity that occurred a hundred years ago, before the Great Eruption. It was one of the manifestations of the Ten Faces of Misery, though it as only categorized as such after the disaster. The calamity was initially unprecedented and irresolvable,[13] making it impossible to eliminate until one of the Seven Shus, Litost, stepped in. Since the people's fear of Amber Street didn't have an actual source, the shadows only kept coming back. Litost resolved the near unstoppable calamity by slaughtering every citizen on Amber Street, ridding it of the shadows. Afterwards, Litost used himself to describe the source of the calamity and to withhold blame for it. By doing such, the remaining fear was directed towards Litost, thus preventing the Great Panic from recurring.[14]

Pool of Shadows

The Pool of Shadows is a phenomenon located in Langqiu that has replaced all the rivers and waterfalls in the area with shadows.[15]

History

Main article: Timeline

The history of Mars is documented using different calendars. The history that is recorded using the Earthian calendar uses the 365/366 days, 12 months in a year format, while history recorded using the Martian Old Calendar uses a strict 668 days, 18 months in a year format, and history recorded using Mars's current calendar (Era of Relocation) uses the 668/669 days, 18 months a year format.[35] Because of this, the calendar differences are specified for each entry via the Earthian years, Old Calendar, and Era of Relocation.

    We have no way of knowing the fate of other cities—at least, the Sea of Data that appeared before our ancestors is constantly eroding the land beneath our feet. In just a few months, Minghai and Baiyu had turned into ruins, and the surviving Langqiu and Oxia were also on the brink of destruction.

    Songque: Huh? Didn't I already cover that? The Great Eruption was going to destroy the entire world, but the Langqiu people refused to accept that, so we used the power of the shadows to defy fate!

    Coralie: The first is about the world itself. Langqiu and Oxia were originally in the same world, split into two by the Shus, a little over a hundred years ago...
    Coralie: Or, to be more precise, by the Shus with Songque as the lead, thereby isolating the Curse in the Shadows in Langqiu, while allowing Oxia to be rebuilt in a brand new bubble universe, unaffected by the Great Eruption.

    DreamseekerDreamseeker: So, city life here relies heavily on the material extracted from the Sea of Data... Source Matter. Oh, on that note, it's similar to what we saw in Langqiu, that Fear Gathering thing.

    Chenxue: Langqiu relies on shadows, while Oxia relies on Source Matter. When compared to either the past or future eras, it feels like we're two worlds evolving along different paths.

    Songque: It's Fear Gathering, although I can understand why you misheard it. As I mentioned earlier, in Langqiu, you can't beat an equivalent exchange, and the Fear Gathering is the way we do business with these shadows.

    Emily: Um... it's nothing. I... I just wanted to ask about the Fear Gathering.
    Emily: Supplies are running a bit low at home.

    Emily: Yes... if things continue like this, I'm afraid he might starve.

    Perception: Well, perhaps you've never heard of the Amber Street Great Panic, but for the man I'm thinking of, it was a great achievement no doubt.
    Perception: Don't worry; this is just a fleeting resurgence. Even if we sit here doing nothing, the memories will disperse on their own.
    Perception: But if you're interested, feel free to roam around and witness Litost's new approach to exorcism that'll happen at a certain point in time.
    [...]
    Perception: Remember the ten manifestations I mentioned—various calamities that come with shadows? The Amber Street Great Panic was one of them.
    Perception: Although later categorized as one of the Ten Faces of Misery, when it first appeared, it was unprecedented, and... there was no known way to resolve it.

    Coralie: Since people's fear of Amber Street doesn't have an actual source, making it impossible to eliminate...
    Coralie: Then, all you need to do is to provide a source.
    Coralie: He killed everyone in Amber Street and used it as evidence...
    Coralie: Claiming that everything was his doing. Right?
    [...]
    Perception: Litost just changed the predetermined ending into a different form and... shifted all the fear of Amber Street onto himself.
    Perception: Since then, he became the object of fear, and Amber Street gradually transformed into what you see today—isn't that a happy ending for everyone?

    Senadina: By the way, I've been meaning to ask you: Are the waterfalls and rivers over there also just shadows?

    The second owner of the pot was a somewhat famous fortune-teller from Langqiu (more skilled in deceit than divination, as is often the case in Amber Street). Sensing an opportunity, she quickly acquired the pot from Josh's household with a few favors.
