The Undersong of the Drithle

The second delegation was smaller than the first — three of the Survey people she already knew, one engineer she did not, and the engineer was not human, which the advance message had said plainly and the valley had spent two weeks not quite believing.

Sorcha met the Chthonari at the shuttle apron and revised, in the first minute, most of what the message had let her imagine. Small — forearm-to-torso small, low and dense, six-limbed, moving over the frost-broken ground with the unhurried competence of something that had never once in its life worried about falling. The guests-under-roofs custom had kept her up two nights over this one; you cannot billet a burrow-dweller in a box bed and call it hospitality. She offered what the holding had: the old stone cold-cellar, cut into the hill behind the house, dry-walled by her great-grandmother's generation. The engineer went in, was quiet for a while, and came out and said — through the flat little voice of a translation pendant — that the cellar held a good note, and that her great-grandmother's people had known what they were doing with a load.

Sorcha had been complimented on the holding before. Never once from the inside of the wall. She found it landed deeper than it had any right to.

The engineer's cargo ran to instruments, as Survey cargo did — ground arrays, this trip, because somebody at the far end of the fold route had read the first visit's report and asked the question the valley had never thought to ask about its own sky: what does a crossing do to the world, while the world is busy watching it. And one item on the manifest was not an instrument, or was, depending on how you held the word. A carry-burrow, sealed for transit. The engineer opened it in the cellar doorway and something small and low and six-limbed came out — kin-shaped to the engineer, a quarter the size — pressed itself flat to her great-grandmother's stonework, and went utterly still.

"It is not equipment," the engineer said, in the tone of an old argument. "There is no form for what it is. There has never been a form. It listens better than my arrays do, and it was owed a rock."

Sorcha looked at the little thing lying against her cellar wall like a hand laid flat on a chest, and did not need the sentence explained. She had dogs that read hills. This read houses. "Then it's a guest," she said, and that was the whole of the paperwork Drithane required.

The new place was loud in the old way.

Not the metal way. Metal talks fast and thin — Eden's walls ring with pumps and doors and the far hum of the rail, everything arriving sharp, everything letting go quickly. Thrum had lived a long time in the fast thin talk and knew every voice in it. This was the other kind. This was rock.

Rock talks slow. The wall of the small den was stone on stone on stone, and under the stone was hill, and under the hill was warm water moving in the dark, a deep patient push that never started and never stopped. The whole world hummed one long low note under everything, the way the home-burrows hummed, the way the first walls hummed, before the metal. Thrum lay flat against the wall and let the note come up through every foot and the soft of the belly, and did not move for a long time, because there was no reason anywhere to move.

The big kin was in the den too, still in the same way. The wall said so. Two hearts on one stone say each other, faintly, through it — that was an old thing from the first walls, and it had not happened since the metal. The wall carried the big kin's weight and warmth and slow breathing, and carried Thrum's back, and the stone held both without effort, the way good stone does.

Above, through the hill, came small things: feet of the four-foot runners on the paths, the house door, water in a pipe, the deep even tread of the tall two-foot who kept this hill. Her steps came down through the ground the way trustworthy steps do, whole and unhurried, each one finishing what it started.

Good walls. Good hill. Good water under it.

Thrum settled into the long low note, and waited, without waiting for anything.

The world changed at dark.

Not the dark itself — dark is nothing, dark is only the eyes, and eyes were never the main thing. What changed came through the ground. The valley's small sounds laid themselves down one by one: the feet stopped, the doors stopped, the pipes stopped, the four-foot runners folded onto the hillside and went from walking-weight to lying-weight, the tall two-foot's tread went out along the lane and then stood still a long way off, planted, like a post. The whole valley put its sounds out the way the burrows bank their warmth. Underneath, the deep water note went on alone.

And then, on top of the silence, so lightly that at first it was only a change in the quality of the quiet: the sky leaned on the world.

It was not a striking. Nothing arrived. It was a pressing — the faintest, widest touch, everywhere at once, like the air itself putting a hand flat on the whole hill and letting the weight of something very high and very slow come down through it into the stone. It rose and thinned and rose, in long slow swells with no edges, a rhythm too big for a body but not too big for a hill, and the hill carried it, and the stone carried it, and Thrum lay against the wall and heard the sky for the first time in any life a vessik had ever had.

The four-foot runners on the hillside were lying in it too. Their weight said so — settled all the way down, the lying of animals inside a sound, not the lying of animals waiting for one.

The big kin's heart, through the stone, went quick and then very slow.

Thrum pressed flat, and listened, and the world was one wall, and the wall was good.

The engineer had asked permission for the ground arrays with the care of somebody who had read a file on the valley's customs, and had asked a second permission, separately, for the two of them — the engineer and the small one — to spend the crossing in the cellar rather than out under the sky with everyone else. Sorcha had said yes to both, and had wondered, walking her dark-down, what kind of guest crosses forty light-years to attend a sky and then asks to spend it indoors, underground, facing a wall.

She got her answer at the gate-turn, past midnight, when the crossing was at its full silent spend and she came back along the lane to check her own roof-line. The cellar door stood open on the dark. Inside, no lamp — a Chthonari needs none — just the engineer, flat to the floor with every limb spread, and the little vessik flat to the wall beside her, neither of them moving, both of them lying against her great-grandmother's stonework the way the herds were lying against the hill. Attending. Not to the sky.

To the ground under it.

The engineer told her, in the morning, what the arrays had caught and the vessik had confirmed — told her carefully, in the manner of a professional handing over something that belonged to the valley more than to the survey. The crossing was not only a sight. A whole hemisphere of slow burning, high up, pressed on the air, and the air pressed on the world, and the world carried it — a signal below any ear, wide as the sky that made it, riding under the valley for exactly as long as the sparks rode over it. Your sky writes on your ground, the flat pendant-voice said. Very lightly. Every crossing. It has been doing so since before your arks.

Sorcha thought about the herds, then. Every crossing of her life she had watched the animals lie down with the valley and stay down, and every generation had called it the custom keeping itself, the beasts quieting with the houses. Nobody had ever asked whether the beasts were listening to something the houses couldn't hear. She asked the engineer if that was the claim. The engineer said, with what the pendant rendered as care, that it was a question now, and had not been one yesterday, and that questions were the only cargo the Survey was licensed to take away.

The pair of them lifted two days later, the vessik sealed back in its carry-burrow — owed a rock, the engineer had said, and paid. Sorcha walked up to the cold-cellar that evening and stood a while with her hand flat on her great-grandmother's wall, feeling nothing, knowing better than she had ever known anything that nothing was not what was there.

The stone held a good note. She had that from the inside of the wall now, and she meant to keep it.
