They stayed three days.
Arthur had intended two. Lyra had not intended to leave at all, which was a position she did not state directly but made clear through behavior — the way she arrived at the archive each morning before anyone else was awake, the way she organized the books by subject rather than returning them to their original positions, the way she had begun writing her own index of the collection in the back pages of her journal because the existing one was, in her assessment, not organized correctly.
Aeryn watched this happen with the expression of someone who had waited a long time for a particular kind of problem and was finding it satisfying to finally have it.
Arthur read the archive's account of the thirty-year conflict from start to finish. It took most of the first day. The account was thorough in the way of someone who had survived something and understood that the details were what mattered — not the broad strokes, not the summary, but the specific sequence of decisions and their consequences. He read it the way he read everything that mattered: once fast to get the shape, once slow to get the content, and then sat with it until the implications settled.
The conflict had a name in the elven records. It translated, roughly, as the Deep Waking.

Aeryn received them each morning in the root-walled building near the central tree.
On the second morning Arthur came in with the list he had been building since the night before — the seven indicators from the archive, written out in his own notation, with the three confirmed ones marked and the remaining four described in his best translation of the original elven text.
He set it on the table between them.
She looked at it. She looked at him.
'You translated that yourself,' she said.
'Lyra helped with two of the terms,' he said.
She picked up the list. She read it in the way she read things — quickly, completely, with the specific attention of someone for whom reading was a tool rather than an activity.
'Your translations are accurate,' she said. 'With one exception.' She pointed to the fourth indicator. 'This does not mean creatures moving toward the surface. It means creatures moving away from the deep. The distinction is directional but the implication is different — away-from suggests they are fleeing something below rather than simply migrating upward.'
Arthur looked at the correction. He updated the notation.
'Walk me through the confirmed three,' he said.
She set the paper down. 'Tsuki's reappearance. You know this one.' She looked at the list. 'The canyon's acoustic changes — the records describe a specific deepening of the resonance that precedes the waking cycle, which has been present for approximately eight months according to our observers. And the ironwood growth rate in the northern quadrant of the forest, which has accelerated in a way that our oldest gardeners say matches the account from eight hundred years ago.'
'Three of seven,' Arthur said.
'Three of seven,' she confirmed. 'The last cycle moved from three indicators to seven over a period of approximately four years before the emergence.' She paused. 'Four years was also the warning time they had to prepare.'
Arthur did the arithmetic. He was seven now. Four years put him at eleven.
'What did preparation look like,' he said.
'Poorly, at first,' Aeryn said. 'The records are honest about this. There was disagreement about whether the indicators meant what the oldest texts said they meant. There was disagreement about the scale of the response required. They lost the first two years to that disagreement.' She looked at the central tree through the window. 'By the time the alliance was fully formed they had two years left. It was nearly not enough.'
'The alliance held,' Arthur said.
'The alliance held because someone made it hold,' she said. 'One person, specifically, who had the particular combination of capability and credibility to sit at a table with five different peoples who did not trust each other and make them act as one.' She looked at Arthur. 'The records are not subtle about who that person was analogous to in the cycle's structure.'
Arthur was quiet for a moment.
'No pressure,' Clara said from across the room, where she had been sitting in the window seat ostensibly looking at the city and actually listening to every word.
◆ ◆ ◆
Aeryn examined Clara's magic on the afternoon of the second day.
Arthur stayed for this, not because Clara needed supervision but because Aeryn had specifically asked him to be present. He sat against the wall and watched.
Clara sat across from Aeryn at the low table with the specific composure of someone who was interested and slightly nervous and was doing a reasonable job of only showing the first.
'Show me something small,' Aeryn said. 'Whatever feels natural.'
Clara held out her hand and produced a small flame in her palm. Aeryn looked at it — not at the flame, at the structure behind it.
'Higher output,' Aeryn said.
Clara increased it. Aeryn looked.
'Stop,' she said. She was quiet for a moment. 'Do you know what your affinity classification is?'
'Fire-adjacent,' Clara said.
'Fire-adjacent is not a classification. It is what you write when the actual classification is not in your reference materials.' She looked at Clara steadily. 'Your affinity is not fire. Fire is the closest common category. What you actually have is closer to what the oldest texts call pure force — the specific magical expression of kinetic energy, which manifests most visibly as heat and combustion because those are the most common outputs of force at the scale a person naturally generates, but which is not fire in the way that a wood-burning hearth is fire.'
Clara looked at her hand.
'What does that mean practically?' Arthur said from the wall.
'It means,' Aeryn said, 'that she is not limited to fire. She has been using the most obvious output of her affinity. The affinity itself is broader.' She looked at Clara. 'A force mage who develops properly can produce directional pressure, structural impact, accelerated movement — the fire is a byproduct, not the product.' She paused. 'You have been, functionally, using ten percent of what you have.'
Clara looked at Arthur.
Arthur looked at Clara and thought of all the spells he could craft using this concept.
Gravity magic! That's it, I am going to craft spells that use gravity to make someone lighter, heavier, to pull and push things.
Aeryn looked between them with the expression she had developed over the past two days for exchanges of this type, which was not quite amusement but occupied the same space.
'I can show you the foundational exercises,' she said to Clara. 'It will take more than an afternoon. But the framework will give you something to work with when you leave.' She looked at Arthur. 'She should work with someone who understands force affinity. The exercises I can give you are starting points.'
'I'll find someone,' Arthur said.
'Or develop the theory yourself,' Aeryn said. It was not quite a suggestion. It was the statement of someone who had spent two days reading his diagnostic capability and had arrived at a conclusion about what he was capable of.
'Probably that,' Arthur agreed.
