Amidst the vast, gloomy landscapes, the colossal mansion stood as an opulent architectural marvel, yet its former glory was now a haunting reminder of bygone times.

Once magnificent, the opulent edifice had fallen into a sinister ruin, ravaged by decades of neglect. Ivy snaked up the crumbling walls, obscuring the intricate carvings that once adorned the façade.

Windows, once welcoming sunlight, now stood shattered and hollow, their frames twisted and contorted.

The ornate roof, a crown of grandeur, sagged under the weight of time and decay.

As Northern stepped through the dilapidated entrance, an ominous darkness enveloped him, as if sentient shadows guarded the mansion, bidding him to retreat.

'Oh oh... quite strong,' he mused, unfazed by the foreboding atmosphere.

Dust and debris littered the once-pristine halls, the echoes of footsteps reverberating through the cavernous spaces.

Northern stared deep into the hall, his form almost blending with the darkness itself.

However, a sliver of light from the strange pair of moons managed to crawl in through the open entrance, barely illuminating the middle of the hall.

Northern paused, surveying his surroundings.

Everywhere, darkness and cobwebs reigned supreme.

The darkness itself felt extraordinary, a premonition tugging at his instincts.

'My gut is right... there is something here. But it's strange...'

Usually, he would have sensed it vividly, but this time, all he had was a vague inkling.

"Anyways... this could be a very good opportunity to put my abilities into practical use and see just how strong they are," Northern muttered beneath his breath.

Following his intuition, Northern trekked deeper into the mansion, bypassing the whirling stairs that led to the upper floors on both sides.

Towards the center, beneath the stairs, the hall delved into a deeper darkness...

...where a terrifying creature lurked.

Northern paused, frowning slightly.

'Oh crap... it's a hellion rank for sure.'

Having faced many such beings, he could discern their power immediately.

'And probably a disaster rank... max a calamity rank. As strong as Night Terror before he consumed the Vestige of the Chaos Prince, maybe.'

A smile curved his lips as he caressed his chin.

These were insights he could not have gleaned before.

'Maybe my sense of danger has been sharpened after facing a maelstrom rank.'

Indeed, he had battled a maelstrom rank monster and an evolving hellion rank immediately after.

It would be odd if he could not gauge their strength now.

"Alright, friend... let's have it," Northern grinned, extending his hand in challenge.

As if responding to his provocation, the terrific creature slowly crawled out of the darkness.

Its hulking form was covered in thick, armored scales of lustrous inky blackness.

A forced grin parted Northern's lips as he craned his neck to envisage the creature.

'Crap, I need to get taller.'

Its elongated body rose to an imposing height of around 6.75 feet (205 cm).

With its sheer size alone, it boasted immense strength, appearing capable of overpowering multiple trained soldiers in combat. Taut muscles rolled beneath its skin like rigid snakes.

Its most chilling aspect was the line of glowing red eyes that hid within its gaping maw – five baleful, unblinking orbs stared soullessly at Northern, hinting at an ineffable intelligence and malice dwelling within this abhorrent form.

The longer he examined those unnatural, burning eyes, the more a sense of primal dread settled in.

At the edge of its grotesque maw was a row of serrated teeth, clearly adapted for gripping, tearing, and dismembering unfortunate prey.

And a slightly long appendage snaked out.

Northern stared blankly for a couple of seconds.

'This is quite strange. I've never seen a monster have its eyes in its mouth.'

He wasn't even sure if those were eyes.

'Something about it looks familiar...'

Like he had fought a similar monster before, but he was certain he would have remembered.

The foreboding creature exuded a chilling air of primal savagery and the ruthlessness of a killer, making even Northern shudder for a second.

They stood apart for a few tense moments, sizing each other up.

Then, the monster moved.

Northern's eyes flung open, barely catching the monster's lightning-fast movement.

Perhaps he had underestimated it due to his newfound abilities.

Belatedly crossing his arms, he was rammed by the monster's head, the impact throwing him out of the deep hall to tumble like a log on the ground.

Coughing and vomiting crimson blood, he struggled to stand.

'Crap. That was one hell of a blow!'

A wide grin parted his lips.

"Looks like this is going to be an even grander battle than I thought."

He sprawled to his feet, malice glimmering in his eyes.

Clasping his hands into fists, he shot to the side as the monster reappeared.

Hauling a swift kick, he twirled through the air, his feet bolting against the monster's thick skin before slamming it onto the ground, causing it to rebound like an elastic ball.

Seizing the moment, Northern delved an elbow strike into the exposed flank of the monster, causing it to crash into the marble floor.

All this happened so swiftly, no mundane eyes could have followed the sequence.

Northern stood upright, stretching his body.

"Wow... it feels so good to be in perfect control of my body. And this armor is so great! I feel like my movements are even easier because of it."

He allowed a delighted smile as the abhorrent monster stood up.

Releasing a soft, eerie growl with smoke crawling out of its maw, the monster shot at him again.

However, Northern was ready this time.

He took the blow with one arm, the Night Terror armor absorbing the damage.

Then, hauling the other hand towards the monster, he opened his fist.

A black lance materialized into his hands, an hair's breadth away from the creature, and ferociously impaled its lustrous hull, rendering it in a spray of black gore.

The creature let out a deafening bestial cry and staggered back.

Northern looked at the sleek, black lance protruding out of the monster's shoulder, carved from what appeared to be dark wood itself.

He wore a distorted smile, his eyes gleaming with the pure menace of a demon.

"No... don't die on me yet"
