The stairwell between Floor 6 and Floor 7 was narrow. Too narrow.

Kael had to turn sideways to pass, his shoulder scraping against walls that felt less like stone and more like cartilage — warm, slightly yielding, breathing. The Shard-seed in his pocket pulsed with each step, as if responding to something deeper in the Tower's structure.

Sera descended ahead of him, her sword drawn, her breathing controlled. She hadn't spoken since they'd left the ledge. The revelation about his mother — about the Tower's true interest in him — had shifted something between them. Not distance. More like... gravity. She stayed closer now. Watched more carefully.

"How many floors before the Warden appears?" Kael asked.

"No pattern." Sera's voice echoed in the tight space. "Sometimes it shows up every two or three floors. Sometimes it waits ten. It depends on how threatened the Tower feels."

"And right now?"

She stopped. Turned her head, just enough to catch him with one dark eye. "You found your mother's Shard. You can hear Whispers that would shatter anyone else. The Tower has been hunting you since before you were born." A pause. "Yeah. I'd say it feels threatened."

---

Floor 7 opened into darkness.

Not gradual — absolute. One step past the threshold and the stairwell's dim bioluminescence vanished, replaced by nothing. Kael couldn't see his own hand. Couldn't see Sera, though he heard her breathing three feet to his left.

"Hold," she whispered. "Let your eyes adjust."

They waited. One minute. Two. The darkness didn't brighten. It didn't soften at the edges or reveal shapes. It was solid — a wall of black pressing against his eyeballs like velvet.

"This isn't adjustable," Kael said. "This is designed."

"Floor of the Blind," Sera muttered. "I've heard about it. Never been here. The Tower creates a lightless space and fills it with things that hunt by sound."

Kael felt his Shards react — the five crystals vibrated faintly against his ribs where he'd tied them inside his shirt, and the Shard-seed warmed against his thigh. Then came the Whispers:

*"Walk softly. It is already listening."*

"Ghost," Kael breathed, barely a sound. "What's in here?"

*"The thing that wears the faces of the dead."*

---

The Warden.

They'd been warned. Pike had mentioned it — the creature that patrolled between floors, the Tower's immune system in humanoid form. Sera had faced it twice and survived, though she'd lost a climbing partner to it the second time. She'd described it as fast, adaptive, wearing the appearance of people the climber had lost.

But description wasn't preparation.

The first sign was a smell — sweet, floral, utterly wrong in this lightless space. Kael recognized it before his brain processed why: lavender and woodsmoke. His mother's kitchen. The scent that clung to her apron when she baked honey cakes on winter mornings.

"Don't breathe it in," Sera hissed, her hand finding his forearm in the dark, gripping hard. "The Warden uses scent-lures. It pulls sensory memories from your Shards and weaponizes them."

Too late. The smell was already inside him, flooding his sinuses, dragging with it a cascade of images — his mother's hands dusted with flour, the kitchen window fogged with steam, her voice humming a song he couldn't name but felt in his bones.

And then, a sound in the dark. Soft. Rhythmic.

Footsteps. Not Sera's — too light, too familiar. Bare feet on wooden floorboards, the way his mother walked in the morning before anyone else was awake.

"Kael." A voice. Warm. Living. Close.

His mother's voice.

"Don't listen," Sera said, but her own voice was strained — something was hunting her too, in the dark, using a different memory.

"Kael, sweetheart. Come here."

The voice came from his right. Eight feet away. Maybe ten. Moving slowly, circling. He could hear the wooden-floor footsteps even though they stood on stone.

*"It is not her,"* Ghost said. *"But it knows everything she knew. Every word she ever spoke to you. Every touch. Every lullaby."*

"How do I fight something I can't see?"

*"Listen deeper. Past the voice. Past the footsteps. The Warden has a heartbeat — but it's wrong. Two beats where there should be one. Find that rhythm. That's where it actually is."*

---

Kael closed his eyes — meaningless in the dark, but it helped him focus. He shut out the lavender, the honey-cake warmth, his mother's voice calling his name with an affection that made his chest ache. He listened.

Sera's breathing. His own pulse. The Tower's background hum, ever-present, like blood in veins.

And there — beneath everything — a heartbeat.

*Tha-thump. Tha-thump.*

Two beats compressed into one. A cardiac stutter that no living thing should have. Coming from — above. Not beside him. Above.

"It's on the ceiling," Kael breathed.

Sera reacted before the words fully left his mouth. She lunged upward, sword thrusting vertically, and connected with something that screamed — not with his mother's voice, but with a sound like tearing metal, high and jagged and wrong.

The darkness shattered.

Not light — the absence of total dark. The floor became visible in shades of deep cobalt, the walls emitting a faint luminescence that had been suppressed. And on the ceiling, twenty feet above them, the Warden clung like a spider.

Kael saw it.

He wished he hadn't.

It was his mother. Or something wearing his mother's body — her face, her hair, her dress — but stretched across a frame that wasn't human. Too many joints. Elbows bending backward. Fingers elongated into claws that gripped the stone ceiling. And the eyes — his mother's gentle brown eyes — but fixed, unblinking, filmed with something silver and reflective.

"That's not her," Sera said. Not for his sake — for hers. Because the face was already shifting, rippling, and for a fraction of a second, Kael saw another face beneath his mother's: a young man, dark-haired, with a scar running from eyebrow to chin.

Sera's brother.

The Warden dropped.

---

What followed was not a fight. It was survival.

The Warden was fast — faster than anything they'd encountered. It moved in bursts, covering ten feet in the space between heartbeats, changing direction mid-air. Its claws left grooves in the stone floor deep enough to lose a finger in.

Sera fought with precision born from years of climbing. She knew where to cut — the joints, the tendons, the places where the face-mask connected to the body beneath. Her blade bit into the Warden's shoulder, and instead of blood, something like static poured out — visual noise, crackling black-and-white distortion that hurt to look at.

Kael didn't fight. He couldn't. His skills were minimal, his body untrained for this kind of combat. Instead, he listened.

The Whispers came faster now, overlapping, urgent:

*"Left — dodge LEFT —"*

He threw himself sideways as a claw tore through the space where his head had been. Rolled on the stone floor, skin scraping, ribs screaming from the impact.

*"The Shard-seed — it fears the Shard-seed —"*

He pulled his mother's Shard from his pocket. It blazed in his palm — not with light, but with heat, a warmth so intense the air around it shimmered. The Warden — mid-lunge toward Sera — stopped. Turned its head, his mother's stolen face contorted in something like recognition.

And fear.

"Kael, whatever you're doing — keep doing it!" Sera shouted, blood running from a gash on her forearm.

He held the Shard-seed forward and walked toward the Warden. Each step felt like wading through water — the Tower's resistance was physical, pushing back, trying to stop him. His heartbeat matched the Shard-seed's pulse — one rhythm, one beat, human and whole.

The Warden backed away. For the first time in its ancient existence, the Tower's guardian retreated. His mother's face melted away, then Sera's brother's, then a dozen others — faces of the dead, flickering past like shuffled cards — until all that remained was a shape. A silhouette. Something that had been human, once, a very long time ago.

*"Go,"* it said. Its real voice — not stolen, not mimicked. A whisper like wind through hollow bones. *"Go, Ashborn. But know this — the deeper you climb, the more of her you'll lose. Every Shard she left in this Tower is a piece of her. And when you've collected them all..."*

It paused.

*"There won't be anything left of you that isn't her."*

Then it scaled the wall and was gone, disappearing into the stone like water into sand.

---

Sera sat on the floor, pressing her sleeve against the wound on her arm. Her hands were shaking — not from pain, but from the face she'd seen. Her brother's face, worn by a monster, looking at her with his eyes.

"You heard its real voice," she said. Not a question.

"Yes."

"What did it say?"

Kael hesitated. Then: "It said the more Shards I collect, the more I become my mother. And the less I stay me."

Sera was quiet for a long time. Then she stood, sheathed her sword, and looked at him with eyes that were tired and fierce and alive.

"Then we'd better make sure you stay you. Now help me find the next stairwell. I'm bleeding and this floor smells like your mother's kitchen and I can't take another minute of it."

Despite everything, Kael almost laughed.

They found the exit — a door carved with the same bone-white symbols — and descended. Behind them, the darkness on Floor 7 exhaled, and the scent of lavender slowly faded, like a memory choosing to let go.

But the Warden's words didn't fade.

*The less I stay me.*

Kael touched the Shard-seed in his pocket. It was still warm. Still pulsing.

And for the first time, that warmth felt less like comfort — and more like consumption.
