**Earth: Day 69, Hour 8**
Nassiri was on the seawall. My mother was beside him. She had her notebook.
"The lens fired," I said.
"We know," Nassiri said. "The Hounds went strange about twenty minutes ago. All of them, simultaneously. Three near the port apertures started moving in circles, then stopped, then went quiet." He looked at me steadily. "What happened."
"The redirect worked," I said. "The Vassal-Link is still at fifteen percent. The Tower didn't get what they were building toward."
"And."
I looked at the harbor. Through the composite perception, I could already feel the difference in the root system's behavior — the dispersal channels running at maintenance rate, quieter, the feeding draw reduced across a significant portion of the network.
"The contraction started," I said. "About six weeks early. The lens energy triggered it when it went through the root channels." I paused. "The apertures connected to those channels will begin closing over the next six to eight weeks. Creature populations near them will lose their substrate source."
My mother wrote something. "Which apertures first."
"The ones with the highest channel density. Based on the root system map — the urban zones. The city here, the major population centers globally." I looked at Nassiri. "The gates that have been the biggest tactical problems are going to start destabilizing within two to three weeks."
He absorbed this. "What does destabilizing look like from a military standpoint."
"The creatures near them will become more aggressive as the substrate drops. Then disorganized. Then — absent. The Hounds especially — they're almost entirely substrate-dependent at this saturation level. When the substrate drops below their minimum, they die or they follow the remaining root channels to the apertures that stay open."
"The remote geology apertures," he said.
"Yes."
He looked at my mother. She was already on the third page of notes.
"I'll start the briefing update for the global call," she said, without prompting.
"One more thing," I said. They both looked at me. "The Tower knows the redirect happened. They built the lens with precision — they'll detect the deflection signature in the substrate. They know the energy didn't reach the Vassal-Link." I looked at Nassiri. "What they do next is the variable."
"How long before they can build another lens," Nassiri said.
"Unknown. Weeks at minimum. Possibly months — substrate lens architecture is not standard Tower technique. This one took sixty-nine days. Whether they have the resources and the will to start again depends on how they assess the situation."
"Which is."
"Their Vassal-Link node is still degraded, the relay stations are gone, their colonial timeline is behind schedule, and the organism they've been calling a Demon King has just begun withdrawing from populated zones." I met his eyes. "From the Tower's perspective: the situation on Earth is getting less exploitable, not more. The window for a viable colonial operation was sixty to ninety days. It passed while I was building a sensitive network."
He was quiet for a moment. "That sounds optimistic."
"It is optimistic," I said. "But the optimism is based on accurate arithmetic. The Tower's colonial program runs on economic logic — the cost of the operation against the projected value of the colonial asset. Every day that passes makes Earth a more complicated asset: more sensitives, less substrate for colonization to leverage, a military network that understands what's actually happening." I paused. "And a sabotaged Vassal-Link that the planetary mana ecology will, within a year, overwrite entirely as it develops."
"The fifteen percent residual."
"It's running in a quarantine partition that the rising ambient mana is gradually filling with noise. In twelve to eighteen months, the residual won't be fifteen percent — it'll be one percent. Then zero." I looked at him. "The Tower has a closing window. They can come at Earth hard, now, before the window closes — or they can cut losses."
"Which do you think they'll do," my mother said, looking up from her notebook.
I thought about Theln. About the quality of attention she'd been giving me since the Manufactured Breakthrough session on Avulum. About the narrowing of her eyes during the Sanctification when she saw something she didn't have a category for yet.
"I think it depends on Theln," I said. "And I haven't heard from anyone on Avulum since Day 30."
The sentence landed in the specific way that things land when you've been not-saying them for a while and then say them.
My mother looked at me. "You haven't heard from Vasir."
"No."
She wrote something. I didn't ask what.
