Chapter 3: What the Delta Keeps

The channel map had been drawn by someone who understood water the way cartographers do — as a surface, not a body. Calder had bought it from a dock-trader three kilometers south of Sluice Nine for six tokens and a half-brick of salt, and the trader had pressed it into his hands with the particular confidence of a man selling something he'd never personally tested. The paper was waxed against moisture and had been folded so many times the crease lines formed their own geography. Where the channel split at what the map labeled SPUR-7, someone had written in margin script so small Calder had to lean close to read it: ask locally.

He'd navigated forty kilometers of drowned delta on worse. He pushed off at first light anyway.

The Shallows took you gradually. That was the thing about them — they didn't announce a transition. The Spire's maintenance docks gave way to half-submerged industrial buildings, their upper floors still inhabited, laundry strung between window frames six stories up. Then the buildings grew shorter and more waterlogged, settling into the silt at angles that suggested permanent defeat. Then the buildings stopped entirely and the water spread out flat and brown and enormous under a sky the color of old tin, and there was no skyline anymore, only channels threading between masses of emergent vegetation — mangrove descendants that had grown forty feet tall on the collapsed roof of whatever had been there before — and the occasional geometric intrusion of a pre-Surge structure surfacing at low tide like something unwilling to fully submerge.
