The candle was a stub. Beeswax, scavenged from the composting grounds' supply shelf. It threw a small circle of light across the work surface, leaving the rest of the storage room in shadow. The flame bent slightly in the draft from the door that wouldn't close properly.

Aldric had the arena diagram spread flat on the stone. It was larger than the scrap-paper sketches from the practice area. He'd spent the afternoon transferring the plan to a full sheet, redrawing the measurements, marking the substrate placement zones with different patterns. Charcoal lines, crosshatching, circles. The bounded stone courtyard, twelve meters by twelve meters, rendered in black and gray on white paper.

Mira sat across from him, her stool pulled close enough that their knees nearly touched under the work surface. She was reading the diagram, her eyes moving from the substrate zones to the approach vectors to the three-meter circle at the center. Her hands were still on the stone, the dirt under her fingernails dark in the candlelight.

"Three layers," Aldric said. He tapped the diagram with the charcoal stub. "Environmental control. Close-range fireball. Arena geometry."

He started with the first layer. Substrate patches, pre-placed during the pre-match preparation period. The rules allowed personal equipment, and substrate patches qualified. They were cultivated products, not pre-cast effects. He'd identified three types for deployment.

"Combustion substrate." He pointed to a zone near the arena's eastern edge. "Smoke on trigger. Thick, persistent. It'll hold for eight to ten seconds in open air, longer if there's no wind. The arena courtyard is walled on three sides, so wind is minimal." He drew a small X at the placement point. "This goes down first. When the match starts, I trigger it from the approach corridor. The smoke covers my movement to mid-range."

Mira nodded. She was following.

"Moisture-retaining moss." He pointed to a zone in the arena's center. "Activated by mana pulse. The stone surface goes slick. Not ice, but enough to disrupt footing. A combat-class student charging forward hits this and has to slow down or risk falling. It buys time."

"Flash-powder fungus." He pointed to two zones near the western wall. "Small charges. They detonate on impact. Light, sound, brief thermal burst. Not enough to cause real damage, but enough to startle. If an opponent's backing toward the wall, they hit one of these and their attention breaks for a second."

He looked at her. "Each layer compensates for Spore's limitations. Smoke covers the approach to three-meter range. The moss slows them down so they're in range longer. The flash-bursts create openings for a clean shot."

"And the arena geometry."

"The courtyard is twelve meters square. The walls are stone, waist-high at the spectator level. The corners create blind spots. If I can funnel an opponent toward a wall, their retreat options narrow. They're either coming forward into the substrate zones or sideways into a corner." He tapped the three-meter circle at the center. "Everything funnels to this. Spore's effective range. The entire plan is designed to get opponents into this circle."

Mira was quiet for a moment. Her eyes moved over the diagram again, slower this time, tracing the sequence. Smoke, moss, flash-burst, close-range fireball. The logic was sound. Each layer was independently viable and mutually reinforcing.

"It works on paper," she said.

"It works on paper."

"But it needs someone to manage the substrate supply during the match. You can't deploy patches and fight at the same time."

"No."

"So that's me."

He looked at her. The candle flame bent in the draft, shadow shifting across her face. She was stating a fact she'd already deduced.

"Yes."

He explained what the role required. Not just placing patches before the match. That was the simple part. During the match, between rounds, she would need to prepare replacement substrate patches. The smoke substrate degraded after use. The moisture moss needed reactivation. The flash-powder charges were single-use. If he won a round and advanced, there would be minutes, maybe five, maybe less, before the next match began. In that time, she would need to assess what had been expended, prepare replacements from the raw materials he'd stage at the sidelines, and have them ready for the next pre-match deployment window.

She would also need to monitor Spore's condition between rounds. The mushroom's fatigue threshold was five shots, but in combat the number would be lower. Two to three effective shots before cooldown and degradation became critical. Between rounds, she would need to apply fresh substrate, check the cap's color and firmness, assess whether the thermal matrix was recovering. If Spore was too depleted to fire, the entire plan collapsed.

"This requires full knowledge," Aldric said. He kept his voice level. "Not just the practical technique I've shared. The complete tactical picture. What each substrate does, why it's placed where it is, how Spore's condition affects the sequence. You need to be able to make decisions in real time about what to prioritize."

Mira was watching him. Her expression was still.

"You're telling me everything."

"I'm telling you what you need to operate."

"There's more you're not telling me."

The statement was flat. Factual. She had been working with him long enough to recognize the edges of his explanations. He shared the operational layer but never the theoretical foundation. The what and the how, never the why beneath the how.

"Yes," he said.

She nodded. She didn't push. Instead, she asked the question that mattered: "What happens if Spore can't fire?"

He answered. Contingency for Spore depletion: retreat to the arena's edge, use remaining substrate patches for defensive smoke and flash-burst, buy time for Spore to recover. If recovery was impossible within the match duration, yield. There was no alternative offensive capability. Mushroom Tamer had no other strain ready. No backup weapon. If Spore couldn't fire, the only option was to survive until it could, or accept the loss.

Mira listened without interrupting. When he finished, she nodded again.

"Alright."

---

The word hung in the candlelight. She accepted it.

Aldric sat back on the stool. His hands were flat on the stone surface. The arena diagram was between them, the substrate zones marked, the three-meter circle clear.

He had to trust her. The tactical plan required it. There was no way to execute the three-layer strategy without a second person managing the substrate supply during combat. He could not perform that role while also fighting. And Mira was the only viable candidate. She knew the workspace, had seen Spore, understood substrate science, and had demonstrated technical competence under the pressure of their joint experiments.

But trust meant sharing power. Full knowledge of his capabilities, even if the theoretical foundation remained hidden, was enough for her to use against him if she chose to. She knew where he worked. She knew what Spore could do. She knew the tactical plan. If she walked to Voss tomorrow and described everything, the institutional challenge would be immediate and devastating.

The memory surfaced unbidden. Veylan's hands. He had given his disciple full knowledge, full access, full authority over three centuries of arcane research. And the knife in his back. The systematic dismantling of everything he'd created, using the very knowledge he'd shared, by the person he'd trusted most.

His hands tightened on the stone surface.

Three centuries of that knowledge, and it had gotten him killed. The instinct was absolute: never again. Never share full capability with anyone. Never create the conditions for another betrayal.

But three centuries had also taught him something else. Attempting to control everything alone was a pattern that created single points of failure. He had been the single point of failure in his previous life. All knowledge concentrated in one person, all authority dependent on one will. And when that person was removed, everything collapsed.

The risk of trusting Mira was real. The risk of not trusting her was operational failure during combat. The plan collapsing because the person executing it tried to do everything alone.

Two kinds of risk. He chose the one he could manage.

"The plan is yours to execute during the match," he said. "Substrate deployment, Spore assessment, between-rounds preparation. You make the calls in real time. I'll focus on the fighting."

Mira's eyes met his. In the candlelight, her expression shifted. She had been handed responsibility, and she accepted its weight.

"I'll need the raw materials staged before each round," she said. "Combustion substrate base, moisture moss pre-activated, flash-powder charges pre-measured. If I'm mixing during the between-rounds window, I'll lose time."

"Done."

"And I need to see Spore fire before the first match. Not the bounded test. I need to see it under my own observation so I can judge the recovery rate in real time."

"Tomorrow morning. Before the assembly."

She nodded. Looked down at the diagram. Her finger traced the three-meter circle.

"This is going to be loud," she said.

"Yes."

"Everyone is going to see."

"Yes."

She pulled her hand back from the diagram. "Then we'd better not waste it."

Mira left. The door swung back on its warped hinges, settling into the frame without latching. It never latched.

The storage room was quiet.

Aldric sat alone with Spore and the candle and the arena diagram on the stone surface. The mushroom's cap turned toward him, the faint warmth visible as a slight heat-haze in the candlelight. The deep red was steady, rich, the binding agent substrate dark and cohesive around the stem.

His hands were still. For the first time all day, they were not working. Not channeling, not measuring, not drawing. They lay flat on the cold stone, empty.

The plan was complete. Three layers, fully specified. Mira's role defined, the trust given. The arena was known. Spore was ready, as ready as a living organism could be for what was being asked of it.

Tomorrow was the Trial. Everything built over seventeen days, the conversion chain, the bounded test, the binding agent, the collaboration, the tactical plan, would be tested in public, under the eyes of an academy that expected him to fail.

He had done everything within his power. His hands lay flat on the cold stone. The preparation was done. What came next was out of his hands.

The candle stub burned lower. The flame bent in the draft. Spore's cap tracked the movement, the warmth steady against the cold.

He let his hands rest. Tomorrow would demand everything they had.
