Classification

Region: The Sablemire Lowlands Designation: River delta and flooded forest Associated House: Sablemire Elevation: At and slightly below the level of the water Climate: Warm, wet, still. Mist through most of the year

Primary Phenomenon: The Mist Carries Sound

Everything about the Lowlands, the House included, comes back to this.

Sound crosses the delta the way it crosses water, and carries far past any distance that ought to be possible. A sentence spoken at conversational volume on one channel arrives whole and clear somewhere between four and eleven miles away.

It rarely arrives where it was aimed. The mist carries a voice along paths unrelated to the direction it was spoken in and delivers it from the wrong bearing, with the words intact. A remark made at a landing at dusk may be heard by a family eating supper two hours' poling away, coming out of the fog apparently from behind them.

Nobody can predict where a sentence will land. Four centuries of attempts have produced no rule that holds for a season.

What follows from it

Most of what outsiders notice about the Lowlands follows from it.

This survey has read the Sablemire doctrine on silence and discipline, as every scholar does, and has usually seen it presented as a philosophical position. It is what living here does to people.

In a country where anything said aloud may arrive intact somewhere out of sight, silence comes naturally to children raised there. The House's doctrine is the written-down version of a habit the delta taught generations before anybody thought to make a principle of it.

In the Lowlands, walk silent is local advice, of the same order as don't drink downstream of the tannery.

Sablemire children are deliberately taught to speak quietly before they are taught to swim. Outsiders can be picked out at half a mile by volume alone, instantly and by everyone, and without malice. They are simply loud, the way a visitor to a library is loud, and everybody local knows exactly where they are.

Terrain and Geography

The delta

Slow, wide and braided. Channels silt up and reopen over a few years, with standing water between them. Through the middle depth is flooded forest, where the trees stand knee-deep in water and the canopy closes overhead.

The Lowlands have no horizon anywhere, and no landmark lasts more than a decade. A grove of stumps is a landmark until it rots, and a bar is a landmark until the river moves it.

Every map of the Lowlands is out of date. Sablemire regard publishing maps as a mildly embarrassing habit of other people, much as a sailor regards a printed tide table for a harbour he has worked all his life.

Navigation is by memory, soundings and the channel registers, which record what was passable last season and are corrected constantly.

The mist

Present most mornings and evenings, and much of the winter. It is water and nothing else. Every attempt to show that the mist is metaphysically unusual has failed, which leaves the sound needing an explanation and this tradition without a candidate.

What grows

Reed in great quantity, flooded hardwood, rice in the managed shallows and fruit on the levees. The Lowlands feed themselves comfortably and export the surplus.

What hunts

The delta's predators hunt by patience and ambush, because in water this slow nothing needs speed.

Two are worth a traveller knowing. The lyre-heron is a wading bird of no danger to a person, and the reason half the ghost stories about the delta exist. It mimics accurately and at length, and what it mimics is whatever the mist has brought it. A heron on an empty channel repeating a conversation from six miles away, in two voices, is the most alarming thing in the region and completely harmless.

The silt-lurker is dangerous. It lies buried and patient and takes people at the water's edge. Sablemire lose people to it every year and have never made much noise about it, which this survey finds characteristic.

Population and Settlement

Stilted, single-storey and rebuilt often.

Nothing in the Lowlands is built to last a century, and Sablemire do not count this as a loss. A house is pitched on piles above the flood line, repaired continuously, and abandoned without ceremony when the channel it served closes. The family takes the materials with them.

The seat is a route rather than a place. Where Sablemire's authority sits this season depends on which channels are open, and it moves. Outsiders find this maddening and take it for evasion, when it is a matter of drainage.

All travel is by boat. There are no roads and nobody expects any.

Economic Value

Sablemire hold the river mouths, so they tax movement instead of goods.

Every barge coming down out of three regions to reach open water pays Sablemire something. The toll is modest and consistently applied, and it has made the poorest-looking region in the Heartlands quietly one of the better provisioned.

Beyond passage there are reed, rice, fish and salt, and the dye.

The dye deserves its own line. A deep black is fixed from delta silt by a process Sablemire have never published, and it holds colour better than anything else in the dominion. Much of the Heartlands' formal clothing is black because of a riverbed in the south, including plenty worn by people who would never think of themselves as connected to Sablemire.

Hazards

Drowning, first and by a distance.

Losing the channel. Rarely fatal, but a party without a local can spend three days finding a way out of somewhere they poled into in an hour.

The silt-lurker, at the water's edge, at dusk.

Fever, seasonally, in the deep flooded forest.

Being overheard, which threatens business more than life, and which every trader who works the delta learns about once.

Open Questions

Why does sound carry? The mist is ordinary water and the channels are ordinary channels. The effect is measurable, repeatable and unexplained, and this tradition has been unable to build even a poor theory.

Why is it undirected? A carried sound arriving further than it should is strange. One arriving from a bearing unrelated to its origin is stranger still, and no proposed mechanism has touched that part.

Does it work on anything but the human voice? Bells and thunder carry normally. This has been tested, and it is the most suggestive result in the file.

How much does Sablemire know about all this that they have not said? They are courteous and they answer questions, and this tradition has still never left the Lowlands feeling it was told everything. We record that as an impression, and mark it as one.
