They found a rest space between floors — a hollow in the Tower's wall, barely large enough for two people to sit with their knees pulled to their chests. The walls glowed a faint amber, warm like embers, and for once the Tower seemed content to leave them alone.

Sera leaned against the curved wall, peeling back her sleeve to examine the gash on her forearm. Three inches long, shallow at the edges but deeper in the center where the Warden's claw had caught muscle. It wasn't bleeding freely — the cold air had constricted the vessels — but it needed attention.

"Hold this," she said, handing Kael a strip of fabric torn from the hem of her undershirt. "Press it there. Hard."

He pressed. She winced but didn't make a sound.

"In my pack — the small glass vial. Brown liquid."

Kael found it one-handed, uncorked it with his teeth. It smelled like burned herbs and pine sap. She took it and poured three drops directly into the wound. Her jaw clenched so tight he could see the muscles jump beneath her skin.

"What is that?"

"Ashweed tincture. Kills infection in cuts from the Tower's creatures. Burns like someone pissed acid on an open nerve." She exhaled through her nose, forcing her breathing steady. "But if you skip it, the wound goes gray within a day, and within three days you lose the arm."

"That's comforting."

"I'm not here to comfort you." She pulled the makeshift bandage tight, tied it with her teeth, and flexed her fingers. They moved. She nodded, satisfied. "I'm here to keep you alive long enough to reach whatever the Tower wants you to reach."

---

They sat in silence for a while. The amber glow pulsed gently — slower now, almost like a resting heartbeat. Kael wondered if this space was intentional. If the Tower created pockets of safety the way a hunter leaves bait near a trap.

"You fought well down there," Kael said.

"I survived down there. Fighting well would mean not getting cut." Sera rotated her shoulder, testing the range. "You, on the other hand, fought like a sack of wet grain."

"I've never been in a fight."

"That's obvious." She looked at him — not unkindly, but with the clinical assessment of someone calculating odds. "You're useful. The Whispers, the Shards, the way the Tower reacts to you — that's valuable. But value means nothing if you die on Floor 8 because you don't know how to dodge a claw swipe."

"So teach me."

The words surprised them both. Kael hadn't planned to say it, and Sera hadn't expected to hear it. She studied his face in the amber light — thin, tired, still shaken from seeing his mother's face on the Warden — and something in her expression softened. Not much. But enough.

"Stand up."

---

The hollow was too small for proper training. So they stepped into the corridor between floors — a spiraling passage of ribbed stone, wide enough to stretch their arms without touching the walls. The Tower hummed around them, neither hostile nor welcoming. Observing.

"First rule," Sera said, facing him. She'd drawn her sword — a short, curved blade, well-used, the hilt wrapped in leather that had long since molded to her grip. "In the Tower, combat isn't about winning. It's about positioning. You don't need to kill anything — you need to not be where its attack lands."

"So — dodge?"

"Dodge is the wrong word. Dodging is reactive. I'm talking about reading." She stepped forward and swung — slow, deliberately, the blade cutting the air a foot from his chest. "Where did I aim?"

"My chest."

"Wrong. I aimed at where you were standing one second ago. By the time my blade reached that point, you should have already been somewhere else." She swung again. "Don't watch my sword. Watch my shoulder. The shoulder commits before the arm. When you see the shoulder roll forward —" she demonstrated, "— you step. Not back. Sideways. Always sideways."

She swung again. This time Kael watched her shoulder — saw the telltale roll of muscle — and stepped left. The blade missed by six inches.

"Better. Again."

They repeated it. Twenty times. Thirty. Sera varied the angle — high, low, sweeping, stabbing — and each time Kael learned to read the preparation before the execution. His body was slow — untrained, gangly, still carrying the softness of a village healer — but his mind was fast. He saw patterns. Catalogued them.

After fifty repetitions, Sera sheathed her sword.

"You learn quick," she said. "Most people need three days to read shoulder commits. You're doing it in an hour."

"I used to assist Elder Maren with surgery. Reading muscle movement was part of the job — anticipating where a patient would flinch before the needle hit."

Sera raised an eyebrow. "Healer training for combat. That's a first."

---

They sat again. Kael's legs ached, his shirt was damp with sweat despite the cold, and his Shards buzzed with residual energy from the exercise. The Shard-seed was particularly active — warm and trembling, like something trying to hatch.

"Sera."

"Hm."

"The Warden wore your brother's face. Underneath mine."

She didn't answer immediately. Her fingers found the cord around her neck — a length of braided leather that disappeared beneath her collar. She pulled it out. A small pendant: a smooth river stone, unremarkable, with a hole naturally worn through its center.

"Torren gave me this. The day I left home to climb. He said it was a charm — that the stone knew the way back." She turned it in her fingers. "He was twelve. He'd found it in the creek behind our house and drilled the hole with a nail for three days because the stone kept cracking." A pause. "He wasn't magic. He wasn't special. He was just a boy who wanted to believe he could protect his sister with a rock."

"When did the Tower take him?"

"Six months after I first climbed. I'd come back — successful, stronger. I showed him my Shards, told him about the floors, made it sound like an adventure." Her voice was steady, but her hand gripped the pendant hard enough to turn her knuckles white. "He went in alone. At night. I didn't know until morning."

"And Ghost—"

"I don't know if Ghost is Torren." She cut him off, sharp. "I've thought about it. The voice — sometimes it sounds like him. Sometimes it doesn't. Ghost knows things Torren couldn't have known. But it says things the way he would have said them." She tucked the pendant back under her collar. "The Tower twists everything. It could be him. It could be a copy. It could be the Tower using my hope as a leash."

They sat with that for a while. The amber glow dimmed, then brightened, as if the Tower itself was breathing.

"You know what's worse than losing someone in the Tower?" Sera said, eventually.

"What?"

"Not knowing if they're lost. Torren could be dead. He could be part of the walls. He could be Ghost, talking to you and unable to say his own name." She looked at Kael, and for the first time since they'd met, her eyes were naked. No sarcasm, no calculation, no pragmatism. Just grief, old and deep and impossible to resolve. "That's why I climb. Not for revenge. Not for answers. Just — to know."

*"She's close,"* Ghost murmured. Kael wasn't sure if the voice meant close to the truth, close to breaking, or close to him.

Maybe all three.

"One more thing," Sera said, standing, brushing stone dust from her trousers. The vulnerability was gone — locked away, door shut, key turned. "Second rule of Tower combat."

"I'm listening."

"If the Warden comes again — and it will — don't use the Shard-seed to scare it off. You heard what it said. Every time you use her Shard, you become more her. There's a cost, Kael. The Tower doesn't give power for free."

"So what do I use?"

"Your own body. Your own instincts. Read the shoulders, step sideways, survive." She almost smiled. "I didn't become a climber because I was strong. I became strong because I refused to be carried."

She started down the corridor, toward the entrance to Floor 8. Kael followed.

Behind them, in the amber hollow, Ghost's voice lingered — barely audible, more feeling than sound:

*"She's right, you know. About the cost."*

A pause.

*"Your mother learned that too late."*

Then silence. And the Tower — ever watchful, ever patient — shifted its walls, closed the hollow behind them, and opened the path ahead.

Downward. Always downward.
