Floor 6 was a library.

Infinite — or so it seemed. Shelves stretched in every direction, floor to ceiling, extending beyond sight into a haze of amber light. The books were real — leather-bound, paper-paged, smelling of dust and age. Kael touched one. Its spine read: *The Testimony of Sera Voss, Climber, Year Three*.

"Don't read those." Sera's voice was tight. She'd already seen the titles.

Kael looked at the next shelf. *The Testimony of Kael Ashvane, Climber, Day Seven. The Testimony of Pike Renner, Climber, Year Two. The Testimony of Dren Blackthorn, Climber, Year Eleven.*

"The Tower records everything," he said.

"I told you — it collects." Sera moved through the aisles, sword drawn, scanning for threats. "But look for the door, not the books."

The books whispered. Not the Tower's Whispers — a softer sound, like pages turning themselves. Each spine glowed faintly when Kael walked past, as if reaching for his attention. *Read me. Read me. Know what I know.*

He resisted. Mostly.

---

They walked for what felt like hours. The library shifted around them — aisles rearranging, shelves sliding, creating new paths and closing old ones. The Tower was playing. Testing their orientation, their patience.

"This floor is a maze," Sera said. "Last time I was here, it took me three days to find the exit."

"Three *days*?"

"There's food in the shelves. Between the books. Look — water bottles, dried rations. The Tower provides for the floors it wants you to spend time on."

She was right. Between volumes of *The Testimony of Someone Kael Had Never Heard Of*, small packages of food and water sat like bookmarks. He grabbed a water bottle and drank.

Ghost had been quiet since entering Floor 6. But now, faintly:

*"Look for the book without a name."*

Kael stopped walking. "Ghost says to find a book without a name."

Sera turned. "Unnamed? Every book here has a title."

"Maybe that's the point. The one that doesn't — that's the key."

---

They searched. Methodically, aisle by aisle, shelf by shelf. Sera took the left side, Kael the right. The books resisted their touch — some burned hot, some froze cold, some sent jolts of emotion through his fingers. He learned to read the Shards' reactions: they pulsed differently near certain books, as if recognizing something within.

Near what must have been the hundredth shelf, Kael's fingers touched a spine with no writing. No title. No author. Just smooth, dark leather, warm to the touch.

He pulled it out.

The book was thin — maybe fifty pages. The cover was blank. But when he opened it, the pages weren't empty. They were filled with symbols he couldn't read, shifting and rearranging like the door markings. And at the center of the book, pressed between pages like a dried flower, was a single Shard.

Different from any he'd seen. Not crystalline — organic. It looked like a seed, dark red, veined with gold, pulsing with a heartbeat that matched his own.

*"Take it,"* Ghost said. *"It belonged to her."*

His mother.

Kael lifted the Shard-seed from the book. The moment his skin touched it, the library *reacted*. The shelves groaned. The amber light flickered. And from every book on every shelf, a single whisper emerged — hundreds of voices, thousands, all speaking the same word:

*"Ashborn."*

---

Sera was at his side in seconds. "What did you do?"

"Found what Ghost told me to find." He held up the Shard-seed. It glowed in his palm, warm and alive. "It was my mother's."

The library began to change. Shelves collapsed — not violently, but gracefully, folding in on themselves like origami. The floor tilted, and ahead, rising from the wreckage of a thousand books, a door materialized.

Not iron. Not stone. *Bone.*

White, polished, carved from a single piece of something that had once been alive and impossibly large. The handle was a vertebra, smooth and cold. And etched into the surface — not symbols, not words — but a picture. A serpent coiled around a leaf.

His mother's pendant. His mother's door.

"That's the exit," Sera said. "But it's different. Last time, it was a normal door."

"Nothing about me is normal. You keep saying that."

She almost smiled. "Fair point."

---

Kael pushed the bone door open.

On the other side — not a corridor. An open sky.

They stood on a ledge — narrow, wind-swept, overlooking a void that stretched below them into absolute darkness. Above, the Tower continued upward, spiraling into clouds that didn't exist. The wind was warm, humid, alive. It smelled like rain.

"We're between arcs," Sera said, reading the space. "The Tower does this sometimes — gives you a breath before the deeper floors. Enjoy it. They get harder from here."

Kael sat on the ledge, legs dangling over nothing. Six Shards now — five crystals and one seed. He held his mother's Shard-seed and felt the warmth, the faint heartbeat.

*"She climbed for fifteen years,"* Ghost said. *"Floor by floor. Alone, for most of it. She reached Floor 30 and found the Heart — the core of the Tower. And she made a choice."*

"What choice?"

*"The choice every Ashborn faces eventually. To open the door — or to become it."*

"And she chose—"

*"She chose you."*

Silence. The wind blew. Somewhere in the void below, something vast and ancient shifted, and the Tower trembled — barely perceptible, like a heartbeat stuttering.

Sera looked at Kael. "What did it say?"

"That my mother chose me." He turned the Shard-seed in his fingers. "Over the Tower. Over everything. She left so she could have me."

"And then?"

"And then the Tower called her back. Or followed her. Or never let go." He closed his fist around the Shard-seed. "The ritual in Thornfield — the one Maren performed — it wasn't random. The corruption in the chant was the Tower reaching through the seal. Finding her. Finding me."

Sera sat beside him on the ledge. Close enough that their shoulders touched. They looked out at the void below and the impossible structure above.

"So the Tower has been hunting you since before you were born."

"Yes."

"And you're going to keep climbing anyway."

"Yes."

She nodded. Once. And said nothing more.

They sat on the ledge between worlds, two climbers at the edge of the deep floors, and watched the darkness breathe below them. Somewhere in the walls — closer now, always closer — Ghost hummed a melody Kael almost recognized.

The melody his mother used to sing.
