The correction worker's name was Renn.
They were sixty-four years old, had begun the work at seventeen, and lived in a house built directly over one of the river delta's primary channels — not by accident, Renn explained, but because forty-seven years of between-space work in a water delta had produced the specific understanding that proximity to the channel infrastructure made the work more accessible.
The water moved through the between-space wound the same way it moved through the physical channel.
Finding the path of least resistance.
Following the gradient.
Going where the wound was deepest because the deepest places were where the pressure differential was greatest.
