We stay until dawn touches the edges of the light above us. Until the aurora fades to a thin line on the horizon and the first sounds of the Verdance waking filter down through the roots. Until the last possible moment before the world demands us back.
Then we stand. We dress. I help her back into the white dress. My hands are gentle, the opposite of how they were an hour ago, and the tenderness of it makes her throat work in a way that makes mine tighten in response.
We climb the spiral staircase back to the surface, and the Verdance greets us with brilliant light and warm air and the distant sound of a city preparing for war.
Tomorrow is here.
We walk into it together.
The sky starts to change at midday.
The pale, steady blue above the Verdance's canopy shifts, bleaching at the edges like fabric left in the sun. The blue drains slowly, replaced by a violet so faint it could be a trick of the light. Except it isn't. Within an hour, the entire sky has turned the color of a bruise, deep purple streaked with veins of darker indigo, and the sun hangs behind it like a lamp behind stained glass, its light filtered and strange.
Irielle confirms what we already know. The boundary is thinning. The Bloomfall Moon will rise tonight.
"Six hours. Maybe less. The boundary is degrading at twice the rate of last cycle." She lifts her hands from the bark and looks at Thalia. "The Cathedral will manifest before moonrise."
Thalia nods once. She turns to Rhyven, who is standing beside her in full armor, the living wood fitted to his body like a second skin. "Begin evacuation. Full protocol."
The city snaps into motion.
The evacuation drills that Rhyven has been running for weeks become real. Families pour through the corridors from the outer ring toward the inner districts, carrying children and supplies and the particular expression of people who have done this before and never get used to it. The root-paths pulse bright with urgency, guiding foot traffic inward, and at every junction, members of Rhyven's defensive force direct the flow with practiced calm.
I watch from the second-ring walkway as the last of the outer-ring residents pass through the reinforced archways. A woman with a baby on her hip stops at the threshold to look back at the tower she's leaving. Her home. The place she rebuilt after the last cycle, knowing she might have to leave it again. She looks at it for three seconds, shifts the baby higher on her hip, and walks through the gate.
The heavy root-gates swing shut behind her. The outer ring is empty now. Sacrificed. A buffer zone between the city and whatever comes through the thinning boundary.
Kaelren is at the eastern ward line with Rhyven, checking the shield channels for the third time today. Thalia is in the Heartwood chamber, coordinating the civilian shelter positions and running final checks on the tunnel network. We split up this morning after the council's last briefing, each of us assigned a sector of the defense plan, each of us doing the work that needs doing before the sky finishes turning.
The plan, such as it is, goes like this: when the Cathedral manifests, the Verdance's layered defenses buy time. The outer shields absorb the initial assault. The ward lines slow the advance. Rhyven's forces engage the Cathedral's root constructs and vine armor at the second-ring perimeter. While the defenses hold, Thalia, Kaelren, and I push toward the Cathedral through the root tunnel system, approaching from below. Thalia anchors the Cathedral. Kaelren and I reach the core.
What we do when we reach the core is the part of the plan that's still unfinished. Torvel's analysis confirmed what we already suspected: the core will resist anything that looks like a tactical approach. It will anticipate force, infiltration, and magical assault. It will counter strategy with strategy, because strategy is what it's built from.
We need something else. Something it can't predict.
We don't have it yet.
That fact sits in my stomach like a cold stone as I walk the second ring, checking shield generators and fallback positions. The generators are charged and humming, their living-wood frames warm to the touch. The fallback positions are stocked with medical supplies and weapons. Everything is ready. Everything except the three people who are supposed to end the siege, who have the anchor but not the strike.
The violet sky deepens through the afternoon. By late day, the indigo veins in the sky have thickened into broad, dark bands that pulse with their own slow rhythm. The temperature drops. The air takes on a metallic taste, like biting down on a copper coin, and the Verdance's bioluminescent moss brightens in response, as if the city is compensating for the dimming light above.
I find Kaelren at the eastern ward line. He's standing with Rhyven and two of the shield technicians, his arms folded, his corruption marks pulsing in time with the ward channels at his feet. The amber glow of the wards reflects off his face, sharpening the angles of his jaw, and his silver eyes are focused on a readout that one technician is showing him. He looks the way he always does before a fight. Still. Focused. Every nonessential function shut down so that the tactical mind can run at full capacity.
"The outer shield held for twenty-two minutes last cycle," Rhyven is saying. "If we get the same duration, that gives us a window to get the tunnel team underground before the second wave hits."
"Twenty-two minutes isn't enough," Kaelren says. "The tunnel approach takes thirty to reach the Cathedral's projected position. We need the outer shield to hold longer, or we need to move before the Cathedral fully manifests."
"Moving before it manifests means crossing open ground without shield cover."
"I'm aware of the trade-off."
"The alternative is overcharging the outer ward," one technician says. She's young, with marks that glow bright green against dark skin. "We could push an extra fifteen percent into the shield matrix. It would extend the hold time but burn out the generators afterward. No second charge."
"Meaning if the outer shield fails, there's no backup."
"Correct."
Kaelren looks at Rhyven. Rhyven looks at Kaelren. Two men weighing the same impossible math, each knowing the other has already reached the same answer.
