The air at the base of the Obsidian Ridge tasted of ozone, dry iron, and the cold, static prickle of unraveling reality.
Eren Vale stood at the edge of the lower basin, his heavy leather coat buttoned tightly against the strange, multidirectional winds that blew through the Fracture. Above him, suspended against a sky of violet and shimmering amber, the jagged cliffside rose like the shattered wall of a forgotten fortress. Up there, half-buried in creeping silver lichen and gnarled alpine roots, rested the ancient ruins that his father had marked on his survey log five years ago.
According to Samuel Vale’s map, the only viable ascent to the upper plateau was a ancient paved trade route known simply as the Forgotten Road.
Eren adjusted the brass calipers on his belt, unclasped his sketchbook, and took a step forward.
[LOCATION ENTERED: Sector F-09 — The Obsidian Ridge Ascent] [Local Reality Density: 61.8%] [Warning: Unstable Spatial Anchor ahead. Terrain cohesion fluctuating.]
Eren narrowed his eyes. His passive skill, [True Direction], hummed in the back of his skull like a clear, resonant bell. Even though the horizon vibrated with optical distortion—making the cliff face appear to bend and stretch like reflection in disturbed water—his internal compass remained unyielding. He knew precisely where true north lay, down to the arc-second.
Ten yards ahead, the wild, mossy dirt of the basin gave way to structured stonework. Massive slabs of dark basalt, four feet wide and deeply carved with interlocking border runes, emerged from the gravel. This was the start of the Forgotten Road. For the first twenty paces, the road climbed smoothly along the cliff's spine, wide enough for two wagons to pass side by side.
Then, without warning, the world gave a sickening shudder.
A sharp, tearing sound—like heavy canvas being ripped in two—echoed through the canyon. Before Eren’s eyes, a fifty-foot stretch of the basalt road simply vanished.
It did not collapse into rubble. It did not slide down the mountain. It ceased to exist.
Where solid stone and ancient wagon ruts had been a fraction of a second earlier, there was now only a yawning, bottomless abyss. Through the gap, Eren could see straight down into the swirling, violet mist of the lower void—a realm of absolute nothingness where gravity had no meaning.
Eren froze, his front boot hovering two inches above the sudden void. Cold sweat broke out along his spine.
"Three paces more, and I would have stepped off the edge of the world," he whispered under his breath.
He pulled his foot back, planting his weight firmly on the stable ground. He did not retreat. Instead, he dropped to one knee, pulled his brass pocket watch from his vest, and watched the empty space.
One second. Two seconds. Three seconds.
POP.
With a sudden, concussive displacement of air that knocked the dust from Eren's lapels, the fifty-foot section of road snapped back into existence. The basalt slabs appeared instantly, solid, moss-covered, and motionless. The ancient runes carved into the stones flickered with a faint, dying blue light before going dim once more.
Four seconds later, the road vanished again.
Void. Stone. Void. Stone.
It was a spatial phase-shift—a localized tear where the physical world oscillated in and out of reality like a flickering candle flame.
"It isn't destroyed," Eren murmured, his dark gray eyes tracking the precise cadence of the flicker. "The land hasn't been erased yet. It's trapped in a phase loop. The spatial anchor holding this section of the ridge to the continent has lost its resonance."
He opened his sketchbook, dipping his horsehair brush into the iron-gall ink.
Most travelers or mercenaries facing a flickering void road would turn back immediately, declaring the pass impassable. Without a high-tier Spatial Mage to bridge the gap or a Guild Anchor Key to force the land into stability, crossing was suicide. Misjudge the timing by half a heartbeat, and you would be standing on solid granite one moment, and falling through endless void the next.
But Eren possessed the vision of a [WORLD CARTOGRAPHER].
When he closed his eyes, his mind did not just see the presence or absence of stone. His spatial awareness mapped the underlying geometry of the phase loop. He could feel the spatial threads stretching thin during the void phase, snapping back together during the material phase, and vibrating at a distinct, measurable frequency.
Manifest phase: 4.2 seconds. Phase gap: 2.8 seconds. Cycle variance: 0.15 seconds per iteration.
"The gap is widening," Eren observed, watching the blue runes on the stone fade further with each cycle. "In a few hours, the material phase will collapse entirely, and this road will be permanently erased from Sector F-09."
He looked up the mountain pass. The flickering section was only the first of three phase tears along the ascent. If he wanted to reach the ancient watchtower and unlock the next tier of his father’s sealed cylinder, he had to map this road—and to map it, he had to cross it while it was still oscillating.
Eren adjusted the straps of his pack, checked the ink well at his waist, and took a deep, steadying breath.
He waited at the edge of the stable stone.
Void... Three... two... one...
SNAP.
The basalt slabs materialized with a thunderous rush of air.
Eren bolted forward.
His boots slammed against the cold, mossy stone. One step, two steps, three steps. His [True Direction] mapped every inch of the basalt under his feet, registering the microscopic cracks in the stonework and calculating the exact center of gravity for the structure.
The story has been illicitly taken; should you find it on Amazon, report the infringement.
Four paces. Five paces. Six paces.
He reached the midpoint of the flickering section just as a high-pitched, metallic whine vibrated through the air—the warning signal of an impending phase collapse.
Under normal circumstances, he would have had to leap across the remaining twenty feet to reach the far cliffside. But Eren had already identified something the scouts had missed.
In the middle of the vanishing section, jutting out from the vertical rock face like a stubborn tooth, was a square stone pedestal—an ancient Spatial Anchor pillar, five feet tall and carved with complex geometric patterns. Unlike the road, which swung into the void, the base of this pillar was anchored directly into the deep mountain bedrock. It did not vanish; it merely became shrouded in spatial distortion mist.
Eren leapt sideways, planting his boots firmly onto the top of the anchor pillar just as the road beneath him vanished into thin air.
WHOOSH.
The world around him dissolved into a swirling vortex of purple light and roaring spatial wind. Void mists whipped around his coat, biting cold and smelling of ancient static. For two agonizing seconds, Eren stood isolated on a tiny three-foot island of granite, surrounded on all sides by absolute nothingness. Below his boots, the endless void yawned like the throat of a colossal beast.
A lesser man would have succumbed to vertigo and fallen into the abyss. But Eren kept his eyes fixed upward, his mind anchored by the absolute certainty of his internal map.
Hold steady. Don't look at the void. Look at the geometry.
He reached into his satchel, pulled out a silver chalk stylus, and bent down over the anchor pillar.
The top of the pillar was covered in intricate, concentric geometric grooves, but the central core was choked with black void-grit and cracked by centuries of decay. The rune network was broken.
SNAP.
The basalt road materialized around the pillar once more, solid and real.
Eren didn't waste a millisecond. He dropped to his knees, pressing his left palm against the cracked center of the anchor pillar while holding his sketchbook open with his right.
"System," Eren thought, channeling his mana. "[WORLD CARTOGRAPHER] — Map Integration!"
A bright, amber light erupted from Eren’s palm, flowing like liquid gold into the concentric grooves of the stone pillar. At the same time, golden lines began to draw themselves across the blank parchment of his sketchbook, perfectly replicating the spatial coordinates of the Forgotten Road, the mountain ridge, and the anchor node.
[SKILL ACTIVATED: Territory Mapping] [Analyzing Local Geometry...] [Spatial Anchor Node Identified: Sector F-09 / Ridge Anchor #1] [Anchor Condition: Severely Damaged (12% Functionality)] [Initiating Mana Alignment...]
As Eren’s spatial mana poured into the pillar, a low, resonant hum reverberated through the stone—not the harsh, tearing sound of spatial decay, but a deep, harmonious tone like a church bell ringing across a quiet valley.
The faint blue runes carved into the basalt road suddenly flared with brilliant, golden light.
The air around Eren stabilized instantly. The fierce, multidirectional winds died down, replaced by a calm, mountain breeze.
Eren looked down at his watch.
Four seconds passed. Five seconds. Six seconds. Ten seconds.
The road did not vanish.
The dark abyss beneath the stones receded, replaced by the solid, granite slope of the mountain bedrock. The fifty-foot section of the Forgotten Road, which had been flickering between existence and oblivion for decades, stood firmly grounded in physical reality once more.
[SPATIAL ANCHOR REPAIRED (PARTIAL)] [Local Reality Density Increased: 61.8% → 74.5%] [Territory Mapped: The Forgotten Road — Lower Ascent] [Map Completion: 4.8% → 8.2%] [Cartography Points Earned: +25 CP] [Total Cartography Points: 90 / 100 CP]
Eren let out a long, ragged breath, wiping a bead of sweat from his forehead. His heart was pounding against his ribs like a war drum, but a fierce, triumphant smile touched his lips.
"It worked," he whispered, looking down at his sketchbook.
On the parchment, the formerly blank, gray section of Sector F-09 had transformed. A crisp, golden line representing the lower trade road now burned steadily on the map, glowing with a warm, permanent aura. Above it, the System interface flickered with updated text:
[NEW ROUTE STABILIZED: The Forgotten Road (Lower Sector)] [Status: Traversable] [Note: Spatial anchor requires full regional map completion for permanent world integration.]
Eren stood up, brushing the dirt and silver lichen from his trousers. He looked back down the trail toward Greyhaven. From this height, the distant obsidian Border Stones looked like tiny black needles sticking out of the earth. The path behind him was clear, solid, and safe.
He turned his eyes back toward the summit.
Further up the ridge, winding through a narrow pass flanked by jagged basalt spires, the Forgotten Road continued its upward climb. He could see two more flickering distortions in the distance, where the path cut through the mountain clouds toward the ancient watchtower.
Ten more Cartography Points. He was only ten points away from reaching the 100 CP threshold needed to decrypt the first layer of his father’s sealed brass cylinder.
Eren closed his sketchbook, tightened the brass clasp, and slipped it safely into his coat pocket.
"Hold on, Father," Eren said quietly to the mountain wind. "I'm finding the way."
He set his boots onto the newly stabilized road and marched upward into the mist.
