Three days later, Aaron asked the question he'd been holding since Solen's office.
He was in the tower foundation chamber, working on the bridgehead — forty-eight percent now, and the work had taken on the particular quality of something approaching a threshold. Each addition felt more significant, each adjustment more weighted. He had Solen's access documentation. No more Sunday-morning timing. He could work in longer sessions, more regularly, without the maintenance staff schedule as a hard wall.
He had been thinking about what Sirath had said about the Shattering. The Source reorganising the world around the intrusion.
"Sirath," he said. He set the crystal down on the stone beside the node and did not pick it up again.
"Yes," Sirath said.
"You knew the risk before the Shattering," Aaron said. "Not the exact outcome — but you knew the attempt might go wrong."
"Yes," Sirath said.
"And you went anyway."
A pause.
"Yes," Sirath said.
"Why?" Aaron asked. Not an accusation. A genuine question — the kind that required the actual answer, not the comfortable adjacent version.
The silence that followed was the particular silence of someone deciding to be fully honest about something they have been partially honest about for a very long time.
"I told you before that the Source was aware," Sirath said. "Responsive. That it reacted to our intrusion." A pause. "What I didn't tell you is what we saw when we approached it for the first time, before the attempt that caused the Shattering. Before the final push." Another pause. "We reached rank ten and found the Source's edge and we looked at it. And what we saw was —"
He stopped.
"Sirath," Aaron said.
"The world was dying," Sirath said. "More precisely — the world was decaying. Not in any timescale a human lifespan could perceive, but in the structural level, in the formation layer that underlies everything, there was a process of degradation that had been ongoing since before any of us were born. The elements were weakening. Not rapidly — at a rate of perhaps half a percent per century. But the accumulation of that rate over millennia means —"
"The elements are less powerful now than they were before the Shattering," Aaron said slowly.
"Yes. And they will be less powerful in another millennium. And in ten millennia —" A pause. "The Source is the generative layer. The elements are its expressions. If the Source grows distant from the world — if the world structure changes such that the connection between the Source and the elements degrades — then eventually the elements cease to be cultivatable. Mages stop being able to gather mage force. Formations stop functioning. The world returns to ordinary physics."
Aaron was very still.
"The world was always going to end," he said. "Not catastrophically. Just — quietly. Losing its magic."
"Yes," Sirath said. "The ten of us saw this. We had different timescales for when the problem would become acute — I estimated forty thousand years, Areth was more pessimistic, Sarel thought we had longer. But we all agreed on the direction." He paused. "And we decided that the only structural-level solution was to touch the Source directly and reinforce the connection. Repair the degrading interface between the Source and the world structure." Another pause. "We were not wrong about the diagnosis. We were wrong about the approach."
"Because you reached for it instead of asking," Aaron said.
"We were also," Sirath said, carefully, "overconfident. Rank ten was the highest cultivation we knew to exist. We believed we were equal to the task." A very long pause. "We were not. The Source's awareness is not comparable to a rank-ten cultivator the way an ocean is not comparable to a cup of water. We touched it and it reacted and the world shattered and —" He stopped.
"And the degradation is still happening," Aaron said.
"Yes. More slowly now, because the formation network's coherence maintenance has a secondary function that I embedded in the design precisely because of this — it slows the interface degradation in the immediate vicinity of the network's nodes. But it cannot stop it. It is not strong enough." He paused. "The formation network buys time. The bridge buys more time. But the root problem —"
"Requires touching the Source again," Aaron said. "But correctly."
"Yes," Sirath said. "Which is why rank nine matters. Which is why the ten of us reached for rank ten. Which is why, despite the disaster of the Shattering, the direction was not wrong." A pause. "And why the organisation's suppression of spatial mage advancement is not merely a power monopoly. If they understand the degradation — and I believe they do — then suppressing advancement that might lead to a second approach is either a protection against repeating the Shattering's disaster, or it is a prevention of the only solution." He paused. "Which intention they have, I don't know. It's the most important question I have and I don't have the answer."
Aaron leaned his back against the chamber wall and looked at the formation in the floor. The three-thousand-year-old bridgehead, designed in the three months before a disaster, waiting at forty-eight percent.
"You built all of this," Aaron said. "The formation network. The bridgehead. The Void Catalog. The inheritance. All of it — knowing that the crossing and the Greensiders and everything after is not the final goal. It's the path to a position where the final goal becomes possible."
"Yes," Sirath said.
"And the final goal is touching the Source again. But gently. Through dialogue rather than force."
"Yes. And I'm not capable of doing it. I'm a voice in a book. The Void Catalog can teach, can design, can advise — but it cannot act. It cannot cultivate. It cannot stand at rank nine and do the structural-level work that addressing the interface degradation requires." He paused. "You can. Eventually. Not now — not for many years. But the trajectory is real."
Aaron looked at the formation for a long time.
"Why didn't you tell me this from the beginning?" he said.
"Because," Sirath said, and his voice was quiet with something that was not quite guilt — older than guilt, more settled, "you were five years old when I found you. And then you were eight. And I was —" He stopped. "I was afraid," he said. "That if you understood the full weight of what I was asking, before you had the strength to carry it — you would either refuse or break under it. And I could not afford to lose you."
"I was a child," Aaron said.
"Yes," Sirath said. "And I handled a child the way I would have handled a senior student approaching rank nine. The way I taught in the era when everyone I taught was already capable of lifting the weight before I showed it to them. I have —" A pause. "I have not been a teacher in three thousand years. And my last era of teaching was in a world with different terms." He paused. "I am sorry. Genuinely."
Aaron sat in the chamber for a while.
The formation pulsed at forty-eight percent.
"I'm not going to break," Aaron said finally.
"I know that now," Sirath said. "I understood it imprecisely at the beginning and more clearly as time passed and I kept adjusting my model of who you are." A very slight pause. "You are not who I expected, when I designed the inheritance. I expected someone older. Someone with an established identity and a clear drive that I could align to the task." He paused. "You are better than what I expected, but for different reasons. Your age means you've grown into this knowledge rather than receiving it complete. The understanding is yours in a way it would not be if you had arrived at thirty."
"That's a polite reframing of a significant mistake," Aaron said.
"It is," Sirath said. "Both things are true."
They were quiet for a while.
"Sirath," Aaron said. "Going forward — the full picture. Not managed timing. Not sequenced releases. I want to know what I'm building toward and what the risks are and what you believe is the correct approach, even when you're not certain."
"Yes," Sirath said.
"And when you don't know something, tell me that too."
"Yes," Sirath said again.
"Good." Aaron picked up the crystal. "Walk me through stage seven of the bridgehead preparation."
A brief pause — not the pause of resistance, but the pause of adjustment. Of a very old mind recalibrating its fundamental operating mode and choosing, consciously, a different way.
"Begin with the northeast node cluster," Sirath said. "There are three interconnected nodes that need to be prepared as a unit — they reinforce each other's function. Start with the outer two before touching the central one."
Aaron placed the crystal against the first node.
He was building a bridge.
He was building a path to a conversation with the thing that had broken the world.
He was ten years old and had eleven months of academy cultivation behind him.
He thought about both of those things and then put them both away, because the node in front of him needed his attention and his attention was what he had.
The work continued.
