The space between Floor 4 and Floor 5 was different.

Instead of a narrow corridor, they emerged into a cavern — wide, high-ceilinged, lit by clusters of bioluminescent crystals growing from the walls like frozen fireworks. Water dripped somewhere, the echo making the space feel vast and cathedral-like.

And they were not alone.

A campfire burned in the center of the cavern — real fire, warm and crackling, fed by something that looked like dried mushroom stalks. Around it sat three figures: a man, a woman, and something that might have been either.

"Well," the woman said, standing. She was short, broad-shouldered, with copper-red hair cropped close and a face full of scars. A war hammer hung at her belt — massive, disproportionate to her frame. "Fresh meat."

"Pike," Sera said. Not a greeting. An acknowledgment.

---

Pike's group had been climbing for two years. The man — a quiet, bearded giant named Torrin — nodded at Kael without speaking. The third figure — androgynous, wrapped in layers of dark cloth, with eyes that reflected the firelight like a cat's — was called Moth. They didn't speak at all.

"Sera Voss." Pike sat back down, gestured at the fire. "Thought you'd died on Floor 15."

"Not yet." Sera sat. Kael followed, cross-legged, the warmth of the fire soaking into his bones. He hadn't realized how cold he'd been.

"Who's the kid?" Pike jerked her chin at Kael.

"Kael. New climber. He can hear the Whispers."

Pike's eyebrows shot up. She looked at Kael — really looked — and her expression shifted from casual to alert.

"How new?"

"Woke up on Floor 1 a few days ago. We've been climbing together since Floor 2."

"Days." Pike let out a low whistle. "Floor 4 in days. That's... unusual."

"Everything about him is unusual," Sera said flatly.

Pike studied Kael. Then she reached behind her and pulled out a cloth bundle, unwrapping it to reveal a collection of items: a short sword, a leather wrist guard, and a pair of boots.

"You look like you need these more than I do."

Kael stared. "I can't—"

"Listen." Pike leaned forward, firelight dancing across her scarred face. "I've been climbing long enough to know: the Tower puts people together for a reason. You're climbing with Sera — which means you're either going to make her stronger or get her killed. I'd rather it be the first one." She pushed the bundle toward him. "Take them. And let me teach you how to hold a sword without slicing your own fingers off."

---

They stayed in the cavern for what felt like a full day — though time in the Tower was unreliable.

Pike was a brutal but effective teacher. She forced Kael through basic drills — stance, grip, the simple geometry of parry-strike-recover — until his arms screamed and his blistered hands wept.

"Again."

"I can barely hold the sword—"

"Good. Your arms are tired, so your body stops fighting your brain. This is when muscle memory starts." She tapped his knee with the flat of her hammer. "Wider stance. Lower center of gravity. You're a healer, not a warrior — so fight like one. Dodge first, cut second, never block if you can slip."

Kael adjusted. Struck again. Pike batted the blade aside like swatting a fly.

"Better. Again."

Sera watched from across the fire, sharpening her sword — the sound of the whetstone a familiar rhythm now. She didn't smile, but something in her eyes said: *good*.

Between drills, Pike talked.

"There's a man in the upper floors. Dren Blackthorn." She said the name like it tasted bad. "Veteran climber. Reached Floor 25 — the highest anyone living has been — and came back. But he came back... different."

"Different how?"

"He thinks the Tower is God." Pike's voice was flat, disgusted. "Started a cult — the Devout. Handful of climbers who worship the Tower, think climbing is blasphemy. They hunt other climbers in the deep floors. Try to 'save' them by sending them back to Floor 1." She spat into the fire. "Or killing them."

"Why would anyone worship this place?"

"Because the Tower gave Dren something nobody else could — purpose. He lost everything to the Blight. Wife, children, farm. The Tower took that pain and turned it into faith." She looked at her hammer. "He's not evil, kid. That's the worst part. He genuinely believes he's saving people."

Kael absorbed this. A villain who wasn't a villain. A monster made of conviction.

"Have you fought him?"

"Once." Pike touched a scar on her jaw — long, thin, precise. "Dren's the best swordsman in the Tower. I barely survived. Torrin lost two fingers." She nodded at the quiet giant, who raised his left hand — the ring and pinky fingers were gone. "We give his territory wide berth now."

Moth, wrapped in their cloth, made a sound — the first Kael had heard from them. A soft click, like a tongue against teeth. Pike glanced at them and nodded.

"Moth's saying it's time to move. They can sense the floor-cycles."

---

Before they parted ways — Pike's group heading toward a lateral passage, Kael and Sera continuing upward — Pike pulled Kael aside.

"Kid. A word."

She was shorter than him by half a head, but her presence made him feel small.

"The Whisper-hearing thing. I've met one other person who could do it. Decades ago, when I first entered the Tower." Her eyes were hard, serious. "She could hear the Tower like you can. Listen to its mood, predict its shifts, find paths nobody else could see."

"What happened to her?"

"She reached Floor 30." Pike's voice dropped. "And she didn't come back."

The same floor. The same number that kept appearing.

"Her name?"

Pike shook her head. "Never got it. But she had a pendant — a healer's symbol. A serpent coiled around a leaf."

Kael's blood went cold.

His mother had worn a pendant like that. He'd seen it in the portrait — the one his father kept on the mantle. A serpent coiled around a leaf.

"I see that look." Pike gripped his shoulder. "Whatever you're thinking — don't let it consume you. The Tower feeds on obsession. The ones who climb for answers usually don't like what they find."

She released him. Picked up her hammer. And walked away without looking back.

Kael stood in the dying firelight, the new sword heavy on his hip, the boots solid on his feet.

Floor 5 waited above.

And in the walls — barely there, almost imagined — Ghost whispered.

*"She was right, you know. Your mother was here."*

Kael looked at the stone. "Who are you?"

No answer. Just silence, and the slow pulse of the Tower's living heart.
