The ruins were quiet in a way that felt deliberate.
Not empty—quiet.
The kind of quiet that came from something having happened here already and not needing to happen again for a while.
Kai stepped fully inside, the pressure from the open plain easing immediately. The walls—broken, uneven stone—cut the wind that didn't exist and the air settled into something more contained. The difference wasn't dramatic, but it mattered. Enough to register. Enough to be useful.
HP: 41 / 580
He didn't sit immediately.
Didn't relax.
He moved along the interior edge first, checking angles without making it obvious he was checking anything at all. The ruins weren't large. A collapsed structure, maybe two rooms once, now reduced to partial walls and an open center. Enough cover to reduce exposure. Not enough to guarantee safety.
Three people were already inside.
They were watching him.
Not aggressively.
Not passively either.
Assessing.
The woman in the middle held his attention first. Not because she was the strongest—he couldn't tell that yet—but because the other two were orienting around her without thinking about it. That kind of positioning didn't come from rank. It came from habit.
Leadership.
Her armor was practical. Not polished. Not decorative. Scratched along the edges in a way that suggested repeated use rather than neglect. The scar through her left eyebrow cut across her expression without softening it. She looked like someone who had made decisions before and would make them again without hesitation.
To her right stood a younger man—Rem, though Kai didn't know that yet—shifting his weight slightly from foot to foot, energy contained but not settled. Not inexperienced. Just not comfortable standing still.
To her left—
Kai's attention paused there for half a second longer than the others.
Grey-blue skin.
Four fingers on each hand.
Eyes completely black.
No visible whites.
Sael.
The kind of presence that didn't need movement to be noticeable.
Kai stopped near the opposite wall.
Not close enough to share space.
Not far enough to signal avoidance.
Neutral.
He lowered himself to sit, the motion controlled, careful not to show how much the fight had taken out of him. The Deepvein rested across his knees. Not raised. Not lowered. Just there.
The silence stretched.
Then the woman spoke.
"You're from 6249?"
Kai's eyes shifted to her.
"How do you know that."
She nodded slightly to his right.
His tag.
Floating beside him.
WORLD: 6249
He hadn't paid attention to it.
Now he did.
"Registration tag," she said. "World number's on it."
A pause.
"Mara."
She tilted her head toward the younger one.
"Rem."
Then slightly toward the grey-blue one.
"Sael."
The younger one gave a small, quick wave.
"Hey."
Sael didn't move.
Kai didn't return the wave.
"Kai."
That was enough.
Rem leaned forward slightly.
"6249 hasn't sent anyone up in years," he said. "We track boards—information from other climbers, floor mechanics, all that—and your world just… stopped showing up."
Kai looked at him.
"What boards."
The question landed.
Not wrong.
Not aggressive.
Just—
off.
Mara and Rem exchanged a look.
Sael's head tilted slightly.
Recalibration.
Mara answered.
"The Tower connects to multiple worlds. Thousands, probably. Each one gets… touched differently. Dungeons start appearing. Instability. Monsters. Most worlds figure it out eventually."
Kai listened.
No reaction.
"Sometimes," she continued, "a dungeon drops something rare. A ticket. Entry into the Tower."
Rem picked up from there.
"You can sell it," he said quickly. "Most people do. It's worth enough to change everything back home. Or you use it. Come here."
Kai leaned back slightly against the wall.
"And people choose this."
Rem hesitated.
"…some do."
Mara didn't hesitate.
"Some have reasons."
That was a better answer.
Kai let that sit.
"Floor 1 isolates," Mara continued. "Same-world only. No crossover. Floor 2 starts bleeding instances. Rare, but it happens. Floor 3—"
"—everything combines," Rem finished. "All climbers. All worlds. Same space."
Kai's gaze shifted slightly.
Not outward.
Inward.
Processing.
World 6249.
No boards.
No information.
No coordination.
One climber.
Him.
He didn't say it.
Didn't need to.
Mara was watching him.
Not with sympathy.
Not with judgment.
Just—
understanding.
"Boss room," Kai said.
"Three-person limit?"
Mara nodded.
"Seals at three."
Kai looked at the passage.
Then back at them.
"Go."
Rem blinked.
"You're not—?"
"No."
Mara studied him for a second longer.
Then stood.
Checked her weapon.
Rem followed immediately.
Sael rose last.
Before stepping into the passage, Mara glanced back once.
"Boss telegraphs left before it goes right," she said.
No explanation.
No elaboration.
Then she was gone.
Rem followed.
Sael paused.
Looked at Kai.
Those completely black eyes didn't reflect anything.
"It went right first," Sael said.
Then he turned and disappeared into the passage.
Kai sat there alone again.
The silence returned.
Different this time.
Not empty.
Full.
He looked at his hands.
Clean.
Steady.
Echo Devour pulsed.
Slow.
Deliberate.
Waiting.
He could feel it now.
More clearly than before.
Not just a tool.
Not just a skill.
Something—
else.
The way it had pulled from the Alpha.
The way his body had moved without him deciding.
The hunger.
The control slipping.
He flexed his fingers.
They responded normally.
That didn't mean anything.
He looked at his HP.
He pulled out a ration.
Ate.
Didn't rush.
Let the numbers climb.
HP: 41 → 191
Better.
Not good.
Better.
Time passed.
He didn't track it precisely.
Didn't need to.
When Mara came back through the passage, she moved the same way she had left.
Controlled.
Efficient.
A small cut along her forearm.
Nothing else.
Rem followed.
A little pale.
Still moving fine.
Sael last.
He stopped again.
Looked at Kai.
"It went right first," he repeated.
Then left.
Kai waited a few seconds.
Not out of caution.
Out of habit.
Then he stood.
Picked up the Deepvein.
And walked toward the passage.
