Aetherbridge is a city defined by water and the order imposed upon it. The Silver River — a wide, slow, patient body of water that arrives grey-green from the inland hills and carries the city's silt, its secrets, and its industry down to the sea — runs east to west through the whole of the city, splitting it cleanly in two. Where it meets the ocean, the river widens into a tidal basin edged with working docks, and the sea itself hovers at the city's western shoulder, salt in the air on certain nights.
Three bridges cross the Silver River, each with its own character and its own traffic, so that a citizen's place in Aetherbridge can often be guessed by which bridge they use and when they use it. The mild climate means the river is rarely wild — it floods only in memory and legend — and so the water has become less a barrier than a kind of social geography: north and south read as separate worlds with a shared address. To know the districts is to understand the city's true ranking system, written not in laws but in neighborhoods, in who rises above the river's banks and who works beside them.
