Chapter 360

The leader of the Moon Watchers, Isna Mielephon.

She pressed her temples hard with one hand, feeling a sharp headache bloom.

‘I’m exhausted….’

Had she ever felt this tired recently?

Thinking back, everything had gone wrong.

Completely tangled.

She held memories of the Closed World, and unlike others she retained her power as well—yet even so, she saw no way to control the current flow of events.

At her side, the man who pledged the deepest loyalty to her approached.

Felibank.

“Commander.”

“Speak.”

“The internal mood isn’t good. Before things get any more tangled, they are asking what we plan to do about him.”

“Garlan?”

“Yes.”

Garlan.

An elder member who led a significant faction within the Watchers.

Outwardly, he looked to act for the salvation of the world—but in truth, his hatred toward Leon was far greater than his fear of the Outer Ones.

In fact, he was quietly gathering those who agreed with his belief that Leon Cascadia should be executed at all costs.

Fighting the Outer Gods, saving the people who needed saving… and now dealing with internal division on top of it—this burden was not something she could easily bear.

“Felibank. Do you think it's possible?”

“What do you mean specifically?”

“Garlan’s fantasy: to kill Leon, and then fight that thing with just us—and win.”

Felibank quietly closed his eyes.

“I am merely your sword. I know how much you shoulder, so I only follow. I will not question you and confuse my master. However… I believe Garlan’s movements risk sparking a civil conflict.”

If he could not help her, then at least he would refrain from hindering her.

But this much, he had to convey.

Such was his answer.

“We’ll need to keep Garlan in check. As for Leon… he was never something we could control. From the very beginning.”

She assessed coldly.

“Do you mean… he’s that strong?”

“He’s nothing like the Leon I know. Far stronger. And he’s wielding powers he didn’t have before.”

Isna possessed immense strength.

But contrary to what the Watchers believed, her power was simply not enough to deal with him.

She spoke calmly.

“Maybe something was different from the beginning. This isn’t a regression we’re dealing with.”

Had it been simple regression, it would’ve been easier.

They could just avert major incidents before they happened.

Indeed, the world followed the previous timeline in many ways—but there were also countless deviations.

Some listed by the Watchers as ‘must-kill’ individuals had apparently experienced some butterfly effect and, contrary to before, had become people who would not betray humanity.

So she chose to save rather than kill.

Garlan and his faction, however, were different.

They detested any situation that escaped their control.

“To be frank… a significant number of the members agree with him. Many have died at Leon Cascadia’s hands after all.”

Rebecca’s recent trip to Baltosma was actually orchestrated by Garlan.

Even so, she couldn’t stop it.

She understood their anger.

Outwardly she appeared unforgiving toward traitors or dissenters, but in truth she was simply sick of this entire situation.

But she could not show weakness, nor could she afford to appear weak.

This was that kind of position.

An unbearably heavy burden pressed on her shoulders.

Had Leon not been the one who killed those members, she might have confessed everything to him and asked for his help.

But Leon had killed most members of the Watchers.

That fact made this two-way hell intolerably suffocating.

Using brute strength to suppress everything was the worst option.

Saving the world was not something she could do alone.

Even so, if Garlan crossed the line…

She would have to draw her sword.

“For now, keep a close eye on Garlan. Focus solely on holding back Dagon’s forces.”

“Yes.”

“In the Closed World, Dagon caused unimaginable casualties.”

If Nyarlathotep was insidious, if Cthugha was destructive, then Dagon was the calamity that—by merely manifesting—had killed one-third of the continent’s population.

Moreover, Isna had no way to kill Dagon.

Pure physical force could not kill one protected by R’lyeh.

Leon was the same—yet this world’s Leon was strangely different.

Perhaps that was why she had forced herself to back him in this meaningless plan.

‘If things are changing so far beyond control… then at least something good has to happen on our side. Right, Lord?’

She closed her eyes.

“They’re coming!! Deep Ones!!”

From the sea, fish-like monsters began to move.

“Felibank.”

“Don’t worry. I won’t let a single one reach the people.”

“No. I’ll handle this alone. Take all remaining members and watch Garlan. I don’t like this feeling.”

“…Yes.”

Felibank bowed and disappeared with a small unit.

The Watchers had many members, but far too many sympathized with Garlan.

And…

A recent incident had killed or incapacitated many of the members who used to keep Garlan in check.

This gave her a very unpleasant feeling.

-Kiiirrk.

As hundreds of monsters crawled out of the water, reeking of blood, Isna slowly drew her sword.

The orichalcum blade Leon had given her ignited with fire.

‘This authority… is something he gave me too.’

The man she trusted most—whose betrayal she still could not understand.

The man who was once her closest friend, making the sorrow twice as painful.

They said his siblings’ deaths and Cascadia’s downfall caused his corruption, but lately Isna wondered if there was another reason.

No matter how the Outer Ones tempted him, she doubted he would succumb so easily.

That doubt had grown stronger recently.

She inhaled sharply and stepped toward the monsters.

Then she manifested her aura in her unique way.

[Nameless Sword]

The sword technique that no one but Leon had ever used unfolded in her hands.

Sword energy rained like a storm upon Dagon’s Deep Ones.

* * *

Riding down the massive underwater passage Nessie created, I descended to the deepest edge of the abyss and placed my hand on a strange structure.

R’lyeh was not just a location.

Anyone could instinctively tell.

“But… how do you open the door?”

If only there were a keyhole.

But the structure before me looked more like an ancient ruin.

“Nessie. Hold on a little. Once the door opens, I’ll send the princess up immediately.”

Nessie wriggled as if displeased, then abruptly closed the massive water tunnel.

An enormous torrent of water crashed down, making the princess scream.

But the water could not pass within 20 meters of us.

Nessie, who had seemed strained earlier, now looked completely fine.

“Oh come on. If you could do that, you could’ve just blocked it around us from the start.”

He turned his head.

Ah.

Got it.

He wanted to look cool.

I see.

When I smirked wickedly, Nessie snapped its fingers and hurled a jet of water at me, which I easily dodged.

Then I pushed the key into the structure.

A repelling energy resisted.

A ward preventing unauthorized entry.

But the key nullified it, and the door opened.

Beyond it was a disorienting, irregular labyrinth.

“If we don’t find the exact path, we’re in for a world of trouble…”

This was supposedly the second key.

What role did the princess even play?

My question lasted only a moment.

She took a step forward.

“I… I think I know the way.”

“Have you been here before?”

“No… but… can you see this thread attached to my chest?”

She pointed at her heart.

I focused my vision.

A faint tether connected her to something deep within the maze.

“So that’s it… you were already consumed… but the creature let you go. If the bait story is true…”

Now I understood why she was called the second key.

R’lyeh expelled intruders but could not sever a line connected to an exit.

She was essentially the only navigation system for this maze.

“This makes it hard to send you back.”

“It’s fine. Either way, if something goes wrong, I die. I’ll lead the way.”

She inhaled deeply and walked with surprising courage.

I warped space and summoned my spirits.

“Sur. Serqet. Grivy.”

All three spirits appeared—a brave chick, a lazy otter, and a tiny girl.

“Protect her. You can do that, right?”

Piiik!

Sur saluted with its wings.

Then I added a few phantoms for coverage, and finally felt reassured.

“How about you?”

I asked Nessie, but it didn’t even hesitate—its body melted into the cracks of space.

R’lyeh seemed shaped by the will of its master.

Following the princess, I entered a massive underwater city.

Though it felt like being submerged, breathing was effortless.

And despite being deep in the lightless sea, the city glowed brightly.

Nessie drifted around, checking its own condition.

“A remarkable space.”

Still, I sensed no survivors.

But one thing stood out.

A pulse of holy power—on par with Luna’s—flaring repeatedly somewhere deep inside.

The Archangel Uriel.

It had to be him.

Then suddenly—

‘Wh-what… how did you enter this place!!’

A terrified voice.

I turned and saw a massive creature, riddled with fatal wounds, barely clinging to life.

Huge by normal standards—but nothing like the titanic eye from my dreams. Shrunken. Withered.

More shocking was its condition.

Its power had become pitifully weak—nothing like what I’d seen before.

Why?

But I understood quickly.

Ah.

It must’ve been damaged when it entered my inner world.

And this was the aftermath?

I scowled, and the creature resisted desperately.

‘Fool!! In this place, things will not go your way! This is R’lyeh! I am its master and ruler!!’

I ordered the spirits to evacuate the princess.

“There are survivors trapped somewhere. Not all, but some are definitely alive. Find them.”

“Y-your lordship… what about you…?”

“I have to hunt that thing.”

One thing was certain.

This was the best—and last—chance to kill Dagon.

“Nessie. Can you help?”

Nessie bowed slowly, gathering a tiny particle of light on its forehead.

Then, before I could say anything, it unleashed a beam of pure energy.

BWOOOON!!! KWA-AAAAAAM!!!

The battle began instantly, the creature howling in agony.

‘How dare you!! Lower being!! You think you can challenge the King of the Abyss!?’

Even if Nessie was strong, Dagon was a monster.

For such a creature to be wounded by Nessie—it meant its guard was wide open.

While its focus was on Nessie, I drew my sword, loading every buff onto my body.

Then, wrapping the Death Authority of Elekstra around my blade, I stepped toward it.

It noticed too late.

But Nessie rammed into it, forcing its attention away from me.

‘Futile! In this place, your sword cannot destroy my core—my origi—’

[Overdrive (Transcendent State)]

[Nameless Sword]

[Swordbreaker Technique]

[Vertical Slash]

A conceptual blade, forged with intent, evolved mid-strike.

The immense load was offset by my buffed physique.

My aura drained visibly—but it didn’t matter.

My regeneration kept up pace with the consumption.

Increasing maximum aura didn’t automatically make one overwhelmingly strong.

Maintaining power was what mattered.

The abnormality in my sword aura made Dagon’s eye widen.

It swatted Nessie aside and thrust a massive arm to block my blade.

But even a single clash made its huge body shudder violently.

‘Damn… damn you!! You monster!! What abomination are you!? I am the lord of R’lyeh! The King of the Abyss and the Dead! Dagon!! I will not die to a worthless—’

I snorted.

“When a buff works, do you know what’s the first thing you can do?”

Before it could answer, I forced my blade’s aura to evolve.

Librarian’s messages flickered in the air.

[Excessive realm elevation detected. Immediate cessation recommended…]

Silence.

Stop?

Why stop?

In a moment like this?

Overwhelming force.

Buff-enhanced physique.

Explosive aura supply.

And finally—

The special nature of R’lyeh that ignored conventional laws.

This was the perfect moment to shatter the wall of Grandmaster.

[Extreme Sword]

[Completed World]

With a single strike, I reached the principle of the world itself.

A realm beyond intent—touching the very foundation of existence.

The first Grandmaster realm opened before me, and the blade pierced through Dagon’s defense, carving a massive wound through its body.

‘KRRRRAAAAAAAGH!!!!’

With a hideous scream, the beast collapsed.

Nessie pounced immediately, smashing its body in fury.

‘No… no… this can’t be… I cannot die… This power… I worked so hard… If only I had not gazed into the Core…’

Its massive eye quivered with terror.

‘Spare… spare me… I’ll…’

I held a finger to my lips.

“Shh.”

Puk!!!

The sword aura from the Ghostblade pierced straight through its brow.

Once, Dagon might’ve been incredibly powerful.

But after sustaining fatal damage to its core in my mind, all that remained was a wounded, dying beast.

Yet a question lingered.

Even if not an Outer God itself, a servant of the Red Moon should still be a world-ending existence.

So how did such a creature collapse so easily?

And what was that “Hall of the Nameless God”—the thing in my inner world that crippled him so completely?

Those unanswered questions churned in my mind.
