They emerged from the flooded cathedral wet, exhausted, and alive.

The exit had come after a harrowing crossing — the walkway had narrowed to inches near the end, and one of the Drowners had surged upward, a pale arm breaking the surface with terrible grace. Kael had slashed at it with Sera's knife — more reflex than skill — and the thing had recoiled, sinking back into the black water with a sound like a sigh.

The Shard from Floor 2 was different from Maren's. Where the first had pulsed with guilt, this one radiated *loneliness*. The aching, hollow loneliness of something that had been waiting in dark water for a very, very long time. Kael held it briefly, then pocketed it. Two Shards now. Two fragments of grief that weren't his own.

Sera sat against the wall of the rest chamber, cradling her bandaged arm. The bleeding had started again during the crossing, but she'd ignored it — pushed through with a focused intensity that Kael found both impressive and alarming.

"Let me re-wrap that," he said.

"It's fine."

"It's not fine. You're pale and your hands are shaking."

She shot him a glare. He held her gaze, steady, until she looked away and extended her arm with a grunt that might have been agreement.

He unwound the soaked bandage. The gash had opened wider — the exertion of the crossing had pulled at the edges. He cleaned it as best he could with water from his shirt — wrung out from the cathedral sludge, but better than nothing.

"You're gentle," Sera said. It wasn't a compliment, exactly. More an observation, spoken with faint surprise.

"I treated patients for three years. Gentleness keeps them from flinching. Flinching makes everything harder."

"Practical gentleness." The ghost-smile returned. "I can respect that."

He tied the fresh bandage — another strip of his shirt, which was rapidly becoming a vest. She flexed her fingers, winced, nodded.

"Half a day's rest," she said. "Then Floor 3."

They rested in silence for a while. Kael leaned against the opposite wall, knees drawn up, eyes half-closed. He wasn't sleeping — couldn't sleep, not here — but the exhaustion had settled into his bones like lead.

"So," Sera said, breaking the quiet. "Thornfield. I've never heard of it."

"Small village. Edge of the Ashlands, near the Greatwood. About two hundred people." He paused. "Had. Had about two hundred people."

"What happened?"

He told her. Not everything — not the details, not the screams — but the shape of it. The Hearthstone. The ritual. The failure. Waking up inside the Tower with nothing.

Sera listened without interrupting. When he finished, she was quiet for a long moment.

"The Hearthstones were connected to the Tower," she said. "That's what the old climbers say. When the Collapse happened — when the mages tried to seal the breach — the Hearthstones were the anchors. Each one held a piece of the seal."

"Maren was trying to repair ours. It had been weakening for years."

"If it shattered, the Tower might have pulled everyone nearby inside. Like a wound closing — it grabs whatever's near and incorporates it." She looked at him with something softer than pity. "You weren't taken because you were special. You were taken because you were close."

He should have found that comforting. He didn't.

"Why do you climb?" he asked.

The softness vanished. Her jaw tightened, and she looked away, toward the corridor that led to Floor 3.

"My brother," she said, flat and final. "He came in three years ago. I followed. He's somewhere in the upper floors." A pause. "Or what's left of him."

Kael waited, but she didn't elaborate. He recognized the silence — the same silence he used when someone asked about his mother. The silence that said: *I've told you all I can stand to tell.*

"We should move," she said, standing. Subject closed.

Floor 3 was a forest.

Not a real forest — or maybe it was, and the word "real" had stopped meaning anything. The corridor opened into a vast space filled with trees — white-barked, leafless, their branches interlocking overhead like the ribs of a cathedral. The ground was mirror-smooth — not ice, not glass, but something that reflected everything above with crystalline precision.

Every tree had a twin beneath it. Every branch, every knot, every shadow existed in duplicate — one reaching up, one reaching down. Walking on the surface felt like walking on nothing, suspended between two identical worlds.

But the reflections were wrong.

Kael saw it immediately. His reflection — the figure that walked beneath him in the mirror-ground — moved a half-second behind. And when he stopped, it didn't stop with him. It kept walking, two more steps, before slowly turning to face upward.

It had his face. His eyes. But the expression was different — older, harder, with a thin scar running from temple to jaw that he didn't have.

"Don't look down," Sera said. She walked with her eyes fixed firmly ahead, boots clicking on the mirror surface. "The reflections show you things. Versions of yourself. Or what you could have been. It's the Tower's way of getting inside your head."

"What does yours show?"

"I told you not to look." Her voice had an edge.

But Kael had already glanced sideways — catching her reflection in his peripheral vision. Sera's mirror-self was walking beside a younger figure. A boy, maybe fifteen, with the same dark hair and gray eyes. He was smiling, looking up at mirror-Sera with obvious adoration.

Her brother.

Kael looked away quickly, but the image stayed.

"The trees are the real danger," Sera continued, as if nothing had happened. "Some of them are doors. You walk between the wrong two trunks, and you end up somewhere else — another part of the floor, or worse, back at the beginning."

"How do you tell which ones are safe?"

"Listen. The safe paths are silent. The doors hum."

Kael strained his ears. She was right — beneath the absolute stillness of the forest, some of the trees emitted a low, barely perceptible vibration. Like a note held too long, just at the edge of hearing.

And then — another sound. Not humming. Not the Tower's breath.

A voice.

*"Kael."*

He stopped walking. Sera turned.

"I hear it," he said. "The Tower. It's—"

*"Kael. Look down."*

Against every instinct, he looked.

His reflection had changed. It wasn't him anymore — not any version of him. A woman looked up from the mirror-ground. Middle-aged, with kind eyes and worn hands. She wore a healer's apron stained with herbs, and her expression was—

He knew that expression. He'd seen it in the single portrait his father kept on the mantle, the one he'd memorized before he could read.

His mother.

"Mom?" The word came out before he could stop it — small, childish, fracturing his carefully maintained composure.

The reflection smiled. She reached upward — her hand pressed against the underside of the mirror-surface, directly beneath his feet. And where her palm touched, the surface rippled.

*"You have your father's stubbornness."* The voice was warm, impossibly real. *"But your gift... that's mine."*

"What do you mean? What gift?"

*"You hear the Tower because I climbed it. Floor after floor. My essence is in you — has been since before you were born. I couldn't protect you from out there."* The reflection's smile faltered. *"So I left something inside."*

"Kael." Sera's hand closed on his shoulder. "Step back. Now."

"She's my *mother*—"

"She's *not*. She's the Tower wearing your mother's face." Sera's voice was low and fierce. "I've seen this before. It gives you what you want to hear, and while you're listening, the forest closes in."

Kael looked around. The trees had moved. Not obviously, not dramatically — but the gaps between the trunks were smaller. The exit, which he could have sworn was fifty yards ahead, was gone. Replaced by more white-barked trees, more mirrors, more reflections.

The forest was contracting around them.

"We need to move. *Now*."

Sera pulled him forward. He stumbled, tearing his gaze from the reflection. In his peripheral vision, he saw his mother's face shift — the warmth draining out, replaced by something cold and hungry. The hand beneath the surface sank back into the depths.

They ran.

Through the trees, weaving between trunks, the humming growing louder as doors opened around them — passages to nowhere, traps disguised as exits. Sera moved on instinct, her three years of climbing condensed into split-second decisions: left, right, straight, *duck*.

Kael followed, trusting her completely because there was no alternative.

The forest fought them. Branches reached down — or up, from the reflections — grasping at hair and clothes. The mirror-ground tilted, warped, tried to swallow their feet. And through it all, the Whispers screamed.

*"Stay. Stay. We have so much to show you. Don't you want to see what you could have been?"*

Kael gritted his teeth and ran harder.

The exit appeared without warning — a door frame standing between two massive trunks, iron-banded, serpent handle. Sera hit it at a dead sprint, yanking the handle down. The door swung open into merciful darkness.

They fell through together.

---

On the other side, silence. Real silence.

They lay on the stone floor, gasping. Kael's lungs ached. His feet — newly cut from the mirror-surface — throbbed. Beside him, Sera had curled onto her side, one hand pressed over her wounded arm, breathing through clenched teeth.

Two Shards materialized between them on the ground, glowing faintly. One for each of them. Kael's pulsed with a new emotion — not guilt, not loneliness, but *longing*. The longing of something that almost had what it wanted.

He picked it up. Three Shards now.

"Your mother," Sera said eventually. "Was she a climber?"

"I don't know." He turned the Shard in his fingers. "She died when I was seven. My father never talked about her past."

"The Tower doesn't lie about everything. It mixes truth with traps — makes the lies harder to spot." Sera sat up slowly, wincing. "If it said she climbed... there might be something to it."

"The Whispers said she reached Floor 30."

Sera's expression was carefully blank. "Floor 30. I've met climbers who've reached Floor 20. Exactly two of them. Floor 30 is..." She trailed off.

"Impossible?"

"Legendary." She met his eyes. "If your mother reached Floor 30, and if whatever she left in you is why you can hear the Whispers — then you're not just a new climber, Kael."

"Then what am I?"

She stood, offering him her hand. He took it. Her grip was strong despite the wound, callused, certain.

"Something the Tower hasn't seen before," she said. "And that scares me more than anything on any floor."

Above them — always above — the Tower breathed. And from somewhere deep within its walls, a voice that was not the Tower's, not his mother's, not anyone he recognized, spoke a single word.

*"Hello."*

Kael's blood went cold.

Sera didn't hear it. She was already walking toward the next corridor, adjusting her sword.

But Kael heard it. Clear as a bell. A third voice — neither warm nor cold, neither threatening nor comforting. Simply *there*.

He followed Sera, but couldn't shake the feeling that something in the walls was watching them.

Something that had been waiting.
