Reborn with a Necromancer System-Chapter 231: The Fortress

The cliff face rose so high that even the clouds couldn't hide its peak. From where Kai stood, its sheer wall of jagged stone vanished into a white haze above, as if the world simply ended somewhere past the clouds. Wind hissed through cracks and ledges, carrying with it the scent of rain and cold rock.

Kai squinted upward, already feeling his shoulders ache at the thought of climbing it.

"You're telling me," he said to Seyren, "we really have to climb all of that?"

Seyren didn't even glance at him, checking the straps on his satchel instead. "Unless you've found a hidden staircase in the past ten minutes, yes."

KKai exhaled slowly and let every thread of magic drain from his body. The faint shimmer of shadow energy bled away, leaving him feeling almost naked without its constant hum. If they can't feel me, maybe they won't look for me.

"You should wait down here, Vep," he said without turning.

"You're not leaving me behind, you idiot," she shot back instantly, crossing her arms.

"But what if-"

"No."

Kai studied her for a moment, then sighed, a small smile ghosting his lips. "Okay, then. Just… be careful, please. I don't know what's waiting for us up there."

So they began.

The climb was slow, their gear dragging at their shoulders, the occasional loose stone forcing them to shift their footing. Mist clung to the rock like a living thing, seeping into gloves and boots until they were damp and chilled. Hours passed in careful silence, broken only by the scrape of boots on stone and the occasional grunt of effort.

About halfway up, Kai's left boot slid off the edge of a slick patch, his balance tipping backward. His stomach lurched. Seyren's tail whipped around his waist, the prehensile appendage locking tight before he could fall. The jolt nearly pulled Seyren from the cliff as well, claws scratching against stone until he managed to brace himself.

"Don't-" Seyren grunted, teeth clenched as they both wavered on the brink, "-do that again."

Kai chuckled faintly once they steadied, though his heart was still pounding. "Noted."

By the time the light began to fade, Kai's arms were sore and his hands raw. They reached an alcove, a shallow recess in the cliff face big enough to shelter them from the wind. Seyren called it for the night, and they set up their small camp, the walls of stone looming like a ceiling far too close. Kai sat there for a long time, staring upward at the faint smear of moonlight far above.

Their limbs trembled from the strain, all except Kai, who stepped onto the rock as though he'd been on a casual stroll. He wasn't sweating. He wasn't even breathing hard.

"Thanks for that back there," Kai said, his voice even.

Seyren turned toward him, brow furrowed in surprise. "Ah… you're… welcome?"

The odd, almost formal reply made Vepice snort. Then her snort turned into a giggle, and within seconds, the laughter spread to all three of them. It echoed faintly against the cliffside, a strange pocket of warmth in the cold shadow of the fortress above.

When the laughter faded, Seyren's expression softened. "My parents used to hide in places like this," he said quietly. "Away from humans. Away from demons. They… they loved each other enough to think they could build a life here. A safe one."

The story came out in pieces, how his mother had been a wanderer from a far-off place, how his father had defied both humans and demons to be with her. How they had been discovered, betrayed by a neighbor desperate to save his own skin.

Seyren had survived only because his mother had forced him into a narrow crevice moments before the attackers arrived. He'd listened to their screams until they stopped, then slipped away into the night.

Kai leaned back against the rock, arms crossed. A part of him suspected this was Seyren's way of binding them together, of making himself less expendable in the eyes of two people who lived in a world where attachments could be dangerous. But even with that suspicion in mind, Kai felt the pull of shared loss.

He knew what it was to grow up with nothing but the shadows for company.

The next morning brought no mercy. They'd barely been climbing for an hour when shadows passed over them, large shapes circling above. Kai looked up to see eagle-like creatures, their wings easily twice the span of a man's arms, talons gleaming like hooked blades. The first one dove without warning, its beak snapping shut with a sound like breaking bone.

They fought them off with their weapons, but the birds were relentless.

The creatures moved with terrifying speed, diving in to strike before retreating skyward again. Every blow was met with another screech, another rush of air as wings battered against their faces. By the time the last of the eagle-things pulled back with a frustrated shriek and wheeled away into the clouds, Kai was left with a shallow cut across his forearm and the pounding of adrenaline in his ears.

"That was breakfast for them," Seyren said grimly. "We're lucky they weren't hungrier."

"That seems to be part of our luck. First in the underdark, and now here."

Seyren nodded in confirmation.

On the third day, the climb grew harsher. The air thinned, the wind howled, and the rock became slick with frost. Kai's breath came in short, sharp bursts, each one a reminder of how high they'd gone. When they finally hauled themselves over the last jagged lip, he collapsed to his knees, pulling in lungfuls of thin, icy air.

Then he saw it.

The fortress stretched across the plateau ahead, its walls blackened with age, towering higher than any castle Kai had ever seen. Spires like jagged teeth rose against the sky, and gates of iron thicker than a man's arm were half-buried in snowdrifts. It wasn't just a fortress, it was a citadel built on the bones of something ancient, the kind of place that had seen centuries of storms and still refused to fall.

Seyren came to stand beside him, staring at the colossal stronghold.

"Welcome," he said quietly, "to the fortress of the demon king."
