Astronomer Royal Vesper of Avarath was, by the chronicle's beginning, a woman in her late fifties who had spent thirty-one of those years inside the cold tower at the edge of the Hold. She had been appointed Royal in her thirties, younger than was usual, by a queen who had, even then, decided that the Astronomer Royal would be an envoy as well as a measurer. Vesper had agreed to the appointment without ceremony. She had not left the tower more than the queen had required of her since.
She was small, grey-haired in the cropped style of working scholars, and dressed in the same weight of wool as the queen — not because the queen and the astronomer matched, but because the cold did not distinguish. Her hands, by the time of the chronicle, were so accustomed to the cold of the lens that they had grown quiet. She did not gesture much. She wrote.
The hesitations
What set her apart from her predecessors — and from every other astronomer on Celesterra — was not the precision of her measurement, which was no greater than her predecessors', but the discipline of her doubt. She had been taught, by the academy that taught Aelinna of Krypton in her later years, that a measurement that confirmed expectation was less interesting than a measurement that hesitated. A hesitating star — a star whose position had moved by a fraction of a degree against the calculated mean — was the kind of measurement that could not be dismissed without first being explained, and explanation, in Vesper's discipline, was where work began.
In the year before the chronicle, she had begun to record hesitations she could not explain. Three nights in a single month, then four, then six. The hesitations were small. They were, in any single instance, within the margin of any reasonable instrument's error. Aggregated across a season, against the catalogue she had been keeping for thirty years, they were not. The stars, she wrote in her own hand, had begun to register — and what they were registering she did not know, only that the direction of the register was eastward, toward the hot zone of Celesterra where the chronicle's anchor mortals were already deep into their first season of catastrophe.
The letters that were not answered
She wrote, accordingly, three letters to Krypton's chancellery in the eight months before the chronicle began. The first asked for a confirming measurement. The second offered to send her data south. The third, the longest, contained the full record of the hesitations and a careful, courteous request for the kingdom to look up. None of the three were answered. The third, she would later learn, was not even opened. She did not blame the chancellor. She had been writing letters into the silence of foreign courts for thirty years and had grown unsentimental about the silence.
She had not, however, expected the silence to be broken by a princess on a winter road.
Stance toward the chronicle
She met Aelinna in S7 at a small carriage stop on the northern pass, and she gave the princess, without ceremony, the master ledger of the hesitations. She did not ask the princess what Krypton would do with it. She did not need to. Vesper had spent her career writing alarms; she had not, until that day, met the person reading them. The ledger left the cold tower in a stranger's carriage, and Vesper, on the walk back to her glass, recorded only that the measurement had at last begun to be transmitted.
She is, in the chronicle's quiet reckoning, the first mortal outside Krypton to have seen. She had been seeing, by her own count, for fourteen months before any kingdom on Celesterra had begun to look.
