The forest swallowed sound.
The moment Eren stepped beneath the canopy, the world changed. The wind thinned, stripped of its edge, replaced by a damp stillness that pressed in from all sides. The trees stood close together, their trunks thick and dark, bark slick with moss and age. Branches intertwined overhead, blotting out the sky and reducing daylight to a dull, green-filtered haze.
The road vanished behind him within minutes.
That bothered him more than he liked.
Eren slowed his pace, letting his senses adjust. The forest smelled of rot and wet earth, of decaying leaves layered thick enough to hide pitfalls and bones alike. Every step sank slightly, boots pressing into soil that gave way just enough to be treacherous.
Hunger stirred.
Not sharply. Not yet.
It lingered beneath his ribs like a held breath, patient and watchful. He ignored it and focused on his footing instead, eyes scanning the ground, the undergrowth, the spaces between trees where something could be watching.
Because something always was.
He moved carefully, placing each step deliberately. Broken branches lay scattered across the forest floor—some old, some not. Animal trails cut through the undergrowth, narrow paths worn smooth by repeated passage. He avoided them instinctively. Paths meant traffic, and traffic meant attention.
A mistake here would not announce itself loudly.
It would simply end him.
The forest did not reward courage. It rewarded awareness.
Eren paused near the base of a massive oak, its roots coiled above ground like frozen serpents. He rested a hand against the rough bark, feeling the faint vibration of life beneath it. Somewhere deeper in the woods, something snapped—a branch, perhaps. Or bone.
His muscles tightened.
He waited.
Nothing followed.
Minutes passed before he moved again, angling away from the sound, choosing denser ground where visibility was limited but approach was harder. The forest pressed in tighter here, undergrowth clawing at his clothes, thorns scraping exposed skin. Blood welled in thin lines along his forearm.
The hunger noticed.
It reacted not with urgency, but with attention.
Eren clenched his jaw and kept moving.
He did not know how long he walked. Time behaved strangely beneath the canopy, stretching and folding in on itself. The light never changed, only dimmed gradually, as if the forest itself were deciding how much of the world he was allowed to see.
Eventually, he stopped near a shallow ravine.
Water trickled along the bottom, slow and murky, choked with leaves and debris. It wasn't clean—but it was water. Eren crouched, scanning the area before approaching. The ground near the ravine was soft, churned by tracks.
Not all of them animal.
That set his nerves on edge.
He knelt anyway, careful, and dipped a cloth into the water, wringing it out before bringing it to his lips. The taste was foul, metallic and stale, but it eased the dryness in his throat. He drank sparingly. Too much too fast could be worse than thirst.
As he stood, the forest shifted.
Not audibly. Not dramatically.
Just enough that his instincts screamed.
Eren spun—
Too late.
Something slammed into him from the side, knocking him off his feet. He hit the ground hard, breath driven from his lungs as roots and stones bit into his back. Claws raked across his shoulder, tearing fabric and skin.
Pain flared, sharp and immediate.
The creature didn't roar. It didn't announce itself.
It moved with the efficiency of something that had killed before.
Eren rolled, narrowly avoiding a snapping jaw lined with uneven teeth. The thing was low to the ground, elongated, its body wrong in subtle ways—too many joints, movements that bent where they shouldn't. Its hide was dark and slick, almost blending with the forest floor.
A forest crawler.
Not a beast. Not entirely.
Eren scrambled to his feet, ignoring the pain in his shoulder. Blood soaked into his sleeve, warm and steady. The hunger surged at the scent, not eagerly—recognizing.
The crawler lunged again.
Eren sidestepped, but his footing betrayed him. His boot slipped on wet leaves, throwing him off balance. Claws grazed his ribs, shallow but stinging. He hissed through clenched teeth and struck back blindly, steel scraping against hardened hide.
The blow glanced off.
The creature recoiled, not wounded enough—just surprised.
That was his mistake.
He had underestimated it.
The forest did not forgive that.
The crawler darted forward again, faster this time, jaws snapping inches from his throat. Eren dropped low, feeling air rush past his face, and drove his blade upward into the creature's underside.
It shrieked then—a thin, broken sound that echoed too loudly in the stillness.
They crashed together, rolling across the forest floor in a tangle of limbs and roots. Eren felt claws rake his back, felt teeth scrape bone. He shoved the blade deeper, twisting, using his weight, his leverage, everything he had learned about ending a fight quickly.
The crawler convulsed, then went still.
Eren did not move immediately.
He stayed there, chest heaving, blood dripping from his wounds onto the leaves beneath him. Pain pulsed through his shoulder and ribs in slow, deliberate waves.
Hunger surged.
Not as a whisper.
As a pull.
Eren pushed himself upright and staggered back a step, breathing hard. His vision swam briefly, darkening at the edges. He wiped blood from his mouth with the back of his hand and stared at the corpse at his feet.
The creature twitched once, reflexive.
Alive enough.
The hunger pressed harder.
Eren's thoughts raced—not with fear, but calculation. He was injured. Bleeding. Alone in hostile territory. The forest would not give him time to recover.
Efficiency demanded action.
He knelt.
The moment his hand touched the creature, the world narrowed.
Heat surged through his veins, stronger than before, coiling tight and heavy in his chest. The hunger bloomed, not ravenous, but pleased. A sensation brushed the edge of his awareness—something like approval, like a structure clicking into place.
For an instant, something almost surfaced.
Not words.
A shape. A pattern.
Then it vanished.
The crawler collapsed inward, its form folding unnaturally before disappearing entirely. No blood. No remains.
Eren recoiled, gasping.
The pain in his shoulder dulled.
Not gone—but manageable.
He flexed his arm slowly, testing it. Movement came easier than it should have. Strength answered him more readily. His breathing steadied faster than expected.
Certainty settled into him.
He was stronger.
Not invincible. Not safe.
But stronger.
Eren stood in silence, listening to the forest. No immediate threats followed. The trees remained indifferent, unmoved by what had transpired beneath them.
That unsettled him more than anything else.
He cleaned his blade with shaking hands and bound his wounds as best he could, using strips torn from his clothes. The hunger receded, satisfied enough to wait.
As he moved deeper into the forest, Eren understood something with unsettling clarity:
The world would not stop him from becoming this.
It would simply step aside and watch to see how far he went.
And the forest—ancient, patient, uncaring—had already accepted him.
