Raven was at Vextar, on the small business of the spring, when the rider came in from the eastern downs.
The rider was a young corporal of the irregulars — one of the men Raven had, in the past three years, begun to use for the work no banner-officer would consent to. He had ridden, by his own report at the gate, three nights without sleeping; he had eaten, on the saddle, what a horse would tolerate carrying; and he had, by the evidence of his coat, smelled smoke for the better part of two of those nights without, on his own count, ever being within a league of the source. The duty officer at the gate had taken one look at him, sent for a senior runner, and put a flask of weak ale in his hand. The runner had taken him to Raven within the quarter-hour.
Raven was at the small folding desk he had, since his return from Darklume, kept in his Vextar office. He looked up. He took the rider in by the small steady method he had used for every rider for thirty years — the dust on the boots, the sweat at the temples, the hand on the cup, the eye that did not, on first registering the major, fully fix.
He did not, before the rider had spoken, allow himself any conclusion.
"Report."
"Sir. The downs are burning."
"Where."
"Begun east of the third milestone on the old shepherd road. By morning of the first day, a circle perhaps a hundred paces across. By evening of the first day, two hundred. By morning of the third, no man would tell you, sir, who had measured the edge."
"The cause."
The rider hesitated. Raven did not press him. He had spent his career taking the hesitations of men who had ridden through nights, and he knew, by the hesitation's small particular shape, that the corporal was not concealing the cause; the corporal had not, on any of his reading, been able to find it.
"Sir. There was no cause."
"There was a cause."
"I do not, sir, dispute that there was a cause. I dispute that any man on the downs has been able, in three days of looking, to find it. There was no lightning. There was no party. There was no camp. There were no tracks, sir, within an hour's ride of the burned edge that I would, on my own honor, swear had been laid by any animal larger than a sheep. The grass burned, sir. It burned in a circle. The circle did not, by my reading, lay in any direction the wind was blowing on any of the three days. The circle, sir, on the morning of the third day, was still."
"Still."
"Yes, sir. Not spreading. Not retreating. Burning at its edge in the same arc it had burned the previous evening. As if, sir, someone had set a line, and the burning was respecting it."
"What is your name, Corporal."
"Esren, sir."
"Esren. Have you slept this week."
"Not since the second day, sir."
"What did you eat in the saddle."
"Hard cheese. A piece of bread. Two apples that were not, sir, very good apples."
"Get him fed. Get him a bed. He rides back at dawn. I ride with him."
"Sir."
"Esren."
"Sir."
"When you have slept, when you have eaten, when you are on the road with me at first light — tell me again, in your own words, the colour of the line at the edge of the burning."
"Sir, I will."
"Don't tell me now."
"No, sir."
He stood from the desk. He went, in the small quiet way of a man who did not announce his rides, to the stable.
By dawn the next day he was on the road.
By dusk on the second day he had reached the third milestone on the old shepherd road. The corporal, who had ridden with him in silence, drew rein at the milestone and pointed, without speaking, at the long pale arc of the eastern horizon.
The arc was burning.
It was not, on first reading, a fire in the ordinary sense. There was no plume. There was no roar. There was no orange. The grass, in the arc, was gone — not blackened, not charred, but taken — and at the edge of the taken grass a thin pale line, perhaps a finger's width, was at the slow steady consumption of the next blade. The wind, by Raven's careful reading, was at three-quarters from the west; the line of consumption was moving, by his careful reading, to the east-by-southeast at a perfectly regular pace, against the wind.
He sat his horse for a long count.
"Esren."
"Sir."
"The colour."
"Sir, the colour of the line is — it is not the orange a fire is. It is paler than that. It is closer, sir, to the colour of an iron rod that has, for a long time, been left in a forge that is otherwise cold."
"Pale."
"Pale, sir. And steady."
"And the line does not flicker."
"It does not, sir."
"Stay with the horses. I am going to walk."
"Sir, I would like to walk with you."
"I have not asked you to."
"Sir."
"Stay with the horses, Esren."
"Yes, sir."
He dismounted.
He walked.
He walked the burned circle for the better part of two days. He walked it from the inside. He walked it from the outside. He measured the radius at four points; the radius was constant to within a hand's breadth. He measured the depth of the take; the take was perfect — there was no root, no stem, no scorched seed, no dead worm. The earth where the grass had been was clean.
He walked, in the second hour after dawn on the second day, to the centre of the burned circle.
At the centre was a stone.
The stone had not been there the previous spring. He had ridden the third milestone in the previous spring on a different errand, and he had, by the small habitual ledger of an officer who had read this country for thirty years, known the stone fields of the downs at the level of each visible stone within sight of the road. The stone at the centre was new. It had not, by any small accumulation of weathering, weathered. It had no moss. It had no crack. It had been laid, by a hand he could not name, at the centre of the circle, on the night the circle had begun.
He approached it slowly.
He did not touch it with his hand.
He set the back of his glove against it, in the small careful way an officer tested a horse's brand for the heat of a recent iron.
The glove smoked.
He withdrew the glove. The leather, where it had touched the stone, was the colour of old parchment. He turned the glove in the morning light. The smell of the leather was a smell he had not, in thirty years, smelled outside a forge.
He stood by the stone for a long count.
He did not, in the count, name the cause. He had, by the careful private ledger of a man who had been keeping it for three years, at last allowed himself certain categories of cause that he would not, before the chronicle had begun, have considered. He had allowed himself the category celestial. He had allowed himself the category infernal. He had allowed himself, with great reluctance, the category neither.
He stood by the stone in the third hour after dawn and did not, in the careful private ledger, write either category against it. He wrote, in the ledger, only the small line he had developed for the measurements he had not yet been told the answer to.
Stone. Centre. Hot to glove. No cause visible. Date, third spring of the chronicle.
He covered the stone with his cloak, weighted it at the corners, and walked back to the corporal at the milestone. The cloak smoked, faintly, at the edge of the stone, and the corporal, who had been at his horse the whole time, did not comment.
"Sir."
"Esren."
"Sir."
"Get me a courier. Two couriers. One to Aelinna. One to Caedrin. Word for word: the east burns without a cause. Sign my name. Send them tonight."
"Sir."
"Esren."
"Sir."
"Do not ride back through the village we passed yesterday. Take the longer road."
"The longer road, sir."
"Yes."
"Why, sir."
"Because the village we passed yesterday did not, on either of our two passings, look at us. I did not, at the time, mention it. I am mentioning it now."
"Yes, sir."
A fire, the chronicler will record, that has no cause has a cause that is choosing to be unprovable; and the warlock, in the careful instrument of his ledger that night, did not, on his own register, find the burning. He knew, by the small steady reading of the chip of black stone, that something had begun to burn his country. He could not, in his ledger, find what had lit it. He sat at the table for the rest of the night and did not, in the small private way of a warlock whose instruments had begun to leave him, allow himself the conclusion either.
There were, this season, two careful men in two cities, each refusing himself a conclusion he had been given the evidence for. Between them, on the eastern downs, a fire that did not name itself was moving; and the moving, on every reading the chronicle would later make of it, had a cause.
The cause had a name.
The name was Phaeren.
The chronicle, that month, did not yet write it.
