The corridor between Floor 5 and Floor 6 stretched longer than any they'd traveled. The walls pulsed with a deeper blue — almost purple — and the air hummed with something heavier than silence.

Kael sat against the wall, five Shards arranged on the ground before him. He needed to understand them. Really understand them. Because something was changing inside him, and he needed to know whether it was the Shards doing it, or him.

"What are you doing?" Sera asked. She was eating — dried fruit from Pike's last gift — and watching him with the careful attention she gave everything.

"Testing something." He picked up the first Shard — Maren's guilt. Held it in his palm. Felt the familiar weight, the slow throb of remorse. Then he did something he hadn't tried before: he *listened*.

Not to the Whispers. To the Shard itself.

---

It started as a sensation — like pressing his ear against a door and hearing conversation on the other side. Muffled, distant. Then the muffling cleared, and Kael heard—

*Voices.*

Not the Tower's Whispers. Not Ghost. *Memories* — fragments of Maren's life, compressed into crystal.

*"The boy shows promise."* Maren's voice, younger, speaking to someone Kael didn't know. *"He has the gift, but he doesn't know what it means. I'll teach him. When he's ready."*

*"And if he's never ready? If the Blight takes Thornfield before—"*

*"Then I'll do the ritual myself. As my master taught me. As her master taught her."*

The voices faded. Kael opened his eyes. His hands were shaking.

"That was Maren," he said. "From before. Before I met him. He was talking about me — about teaching me—"

"Wait." Sera set down her food. "The Shard *talked* to you?"

"Not talked. More like... a recording. A memory stored inside."

Sera's expression was unreadable. "I've been carrying Shards for three years. They've never done that for me."

"Maybe you need to listen differently."

"Or maybe it's a you thing." She stood, crossed her arms. "What else did it say?"

Kael picked up the second Shard — the Drowner's loneliness. Listened.

---

*Darkness. Water. Waiting.*

*She had been someone once. A teacher, maybe, or a healer — the memories were too fragmented to assemble. What remained was the emotion: the vast, crushing emptiness of being forgotten. Not abandoned — people couldn't abandon what they didn't remember existed. She'd simply... faded. The world moved on and she stayed, pinned to the Tower's walls like a butterfly in a collection, preserved and utterly alone.*

*"They don't hear me anymore." The voice was thin, distorted, like sound through water. "I speak, and the walls absorb the words. I scream, and the silence devours the scream. How long has it been? How long—"*

Kael pulled away. The Shard burned cold against his skin.

"The Drowner wasn't a monster," he said. "She was a person. Trapped in the Tower so long she forgot her own name."

Sera's face hardened. Not in anger — in recognition. "The Tower absorbs climbers who fail. Their bodies become part of the structure. Their minds become—"

"Whispers."

The word landed between them like a stone.

"The Whispers are trapped climbers," Kael said slowly. "They're not the Tower's voice. They're the voices of everyone who died here."

Sera sat down. Slowly. Like her legs had decided to stop working.

"If that's true—" She stopped. Started again. "If the Whispers are climbers — then Cade—"

"Might be one of them."

She pressed her hands flat against the stone floor, breathing carefully. Not panicking. Processing. Sera processed like she fought — methodically, one piece at a time.

"Ghost," she said. "The voice you hear. The one I can't."

Kael picked up the longing Shard — the third. Held it, listened.

Nothing. Just the ache of wanting something just out of reach. But between the wanting and the silence, a faint rhythm — *tap, tap, tap* — like fingernails on stone.

Like someone knocking from the other side of a wall.

"Ghost is different from the Whispers," Kael said. "The Whispers are a chorus — hundreds of voices merged together. Ghost is *one* voice. Separate. Clearer." He paused. "What if Ghost kept some of himself? Didn't fully merge with the Tower?"

Sera's eyes were bright. Painfully bright.

"Cade was strong-willed," she said. "Stubborn. If anyone could resist being absorbed—"

She didn't finish the sentence. Didn't need to.

---

They traveled in silence after that. Kael experimented with the Shards as they walked — holding each one, listening to the fragments within. The two new Shards from Floor 5 were richest: they contained not just emotion, but *knowledge*. Snippets of information about the Tower's construction, its purpose, its rules.

One fragment in particular stood out:

*"The Tower was not built. It grew. Like a vine, like a coral reef, like a tumor. It feeds on the Blight — or the Blight feeds on it. They are the same organism, mirror images, and the Tower is the seal between them. The summit is both lock and key."*

Kael repeated this to Sera.

"A seal," she said. "Between what and what?"

"Between the world and whatever the Blight comes from."

"And reaching the top—"

"Might break the seal. Or reinforce it. The Shard wasn't clear."

Sera walked faster. "Then we need to understand before we get there."

Ahead, the corridor widened. The blue light deepened to indigo. And from somewhere above — always above — Ghost spoke.

*"You're learning faster than she did."*

"My mother?" Kael asked aloud.

*"Your mother."* A pause. *"She took forty floors to understand what you grasped in five. But she had something you don't."*

"What?"

*"Time."*

The corridor opened into the entrance of Floor 6. The door was different — not iron-banded, not serpent-handled. This door was carved from a single piece of bone-white stone, and the symbols etched into its surface shifted when Kael looked at them, rearranging themselves into words he almost recognized.

"New floor, new rules." Sera drew her sword. "Ready?"

Kael gripped his own sword — lighter than it looked, balanced like an extension of his arm. Five Shards hummed in his pocket. Ghost whispered in the walls.

He pushed open the door.
