Oxia 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

Nestled in the vast Sea of Data, Oxia stands as a lone island city, proudly upholding and recounting the Luoxing culture. As Luoxing crumbled, the people of Oxia rooted themselves in the Sea of Data to build a fresh civilization and order. Today, the scars left by the Great Eruption have faded with time. Thanks to the Sea of Data, Oxia has blossomed into a thriving, modern metropolis.[3]

Oxia 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, Langqiu.[2] However, it was not the Great Eruption that split Oxia and Langqiu apart; rather, it was the Seven Shus who caused the division, placing the Curse of Shadows within the isolated Langqiu.[6]

Oxia as a city relies on Source Matter for development.[7] It essentially runs the daily lives of those in Oxia, with even their natural gas and food[8] being refined from it.[9]

    Let's rewind time back to the 33rd day of the 14th month of the year 2185 of the old calendar—the scholars of the old world had predicted this day's arrival.

    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.

    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.
  7. Part 2 Chapter II, Starless Journey
    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.
