Imagine Morrow, a city built where a river delta meets a rising sea. It doesn’t try to hold the water back. Instead, it rises, floats, and occasionally moves out of the way.

Architecture. The oldest districts are half-submerged: ornate stone façades visible beneath clear water, their upper floors connected by bridges. Newer neighborhoods sit on buoyant platforms anchored to the riverbed. They rise and fall with the tide, so the view from your apartment changes by several meters each day. Slender towers grow from the few patches of solid ground, with open, wind-cooled lower floors and shaded gardens wrapped around their exteriors.

Nothing in Morrow has a permanent ground level. Shop signs display their current entrance height; deliveries arrive at different doors depending on the tide. Buildings collect rainwater, cultivate algae on their sunward walls, and trade surplus power with their neighbors. The wealthy live in stable towers. Everyone else takes pride in floating homes they can repair, rearrange, or tow to a different district—though the city has begun restricting where they may anchor.

Transportation. At street level, there are no streets. Electric ferries run frequent routes through broad canals, while small autonomous boats serve the narrower ones. Above them, covered pedestrian bridges link markets, schools, and transit hubs. Their joints flex as the floating districts shift. Cargo travels at night on slow barges; during the day, the canals belong mostly to commuters and vendors.

A cable railway crosses the city overhead, providing a reliable route when storms close the water. Its stations are prized real estate. Private aircraft exist, but strict noise rules and violent coastal winds make them impractical for everyday travel. Locals give directions by current and tide as often as by distance: “Take the eastbound water after the turn.”

Culture. Morrow’s calendar follows the moon. High-tide festivals fill the bridges with food stalls and lanterns; low tides expose old plazas for concerts and salvage markets. Children learn to swim before they learn to ride a bicycle. Boat mechanics and structural divers have the status that architects once did. Hospitality matters, because anyone might someday need shelter when a storm comes in early.

The city’s central argument is about permanence. Tower residents want fixed borders, predictable taxes, and a grand seawall. Floating-district residents see those plans as an attempt to pin them down—or push them out. Meanwhile, the submerged old city is becoming accessible again during unusually low tides, revealing sealed archives, abandoned infrastructure, and uncomfortable evidence about who was saved when the water first rose.
