Casting all hesitation aside, I raised my arm and signaled the knights behind me to advance.

  Thirty royal guards answered in unison, their battle banners snapping in the wind.

  I spurred my horse forward, following the direction Lilia pointed, heading toward the sacred ground of the elven people — the Gaia Ridge.

  Lilia had not exaggerated.

  The road leading to the sacred ground was blanketed by layer upon layer of magical barriers, like an invisible web cast over the entire forest. The air was threaded with streams of mana that were nearly impossible to detect with the naked eye — each one like a strand of light drawn impossibly thin, flickering in and out of view between the leaves. When they brushed against metal armor, they produced the faintest hum, as if reminding every intruder: you have stepped inside something alive.

  Every footfall felt like pressing down on the nerves of the world itself.

  The vines running through the undergrowth were vivid to the point of unreality — deep violet flower clusters, flame-orange fruit, ivory-white moss. Had Lilia not caught my outstretched hand in time, I would have reached out and plucked one without a second thought. The toxins within, she told me, were enough to bring an entire human squad to a silent end within half a quarter-hour — no screams, no struggle, simply a quiet and absolute cessation of breath.

  This was not a "forest."

  This was a natural fortress, reshaped across a thousand years with painstaking precision — the first wall the elven people had built, using time itself as their mortar.

  It was only when we truly reached the base of the Gaia Ridge that I understood how shallow every image I had formed in my mind had been.

  That was not a tree.

  It was a nation.

  The root system of the Gaia World Tree announced itself first — vast roots surging up through the earth, each one as thick as a city wall, winding outward for hundreds of paces before finally disappearing beneath the soil. Between them, natural archways and ramparts had formed, and in every crevice, bioluminescent moss had taken hold, casting a cold light that wove together deep blue and forest green, until the entire root-scape glowed like a palace at the bottom of the sea.

  And the trunk itself —

  I tilted my head back, tracing the bark upward with my gaze, and could not find the top.

  It was a dizzying height unlike any I had encountered — not the sheer danger of a mountain cliff, but something more total, a boundless vertical pressure that simply swallowed you whole. The grain of the bark ran half an arm's length deep, and between every groove sat solidified amber-colored resin, each pocket sealing away centuries of accumulated mana. Where sunlight struck it, the entire trunk seemed to wear a shifting coat of antique gold — silent and sovereign, as though it had stood on this ground since before the concept of time was invented.

  By conservative estimate, the trunk was no less than three hundred paces in diameter.

  Enormous boughs extended from the trunk like rivers running out of a continent, the lowest of them still dozens of zhang above the ground. Upon them, platforms of ancient timber and braided vine-rope had been layered one atop another, reaching upward without apparent end, each level wide enough to house an entire village. Wooden lifts traveled steadily between the platforms, carrying supplies and people, the sound of their pulleys grinding against rope cables carrying through the canopy — the quiet heartbeat of this kingdom of wood.

  Occasionally an elven warrior would pass through the boughs overhead, moving with a lightness that made the forest birds look clumsy by comparison.

  Thousands of platforms stacked upon thousands of platforms, composing a three-dimensional city suspended in the sky.

  There was cooking smoke. There were lanterns. There was the laughter of children drifting down from some platform far above, mixing with the smell of burning pine and the perfume of flowers no human had ever named — an entire world, self-contained, existing above our heads.

  I said nothing for a long moment.

  My instincts as a commander took hold before I could stop them, and I began running simulations of how one might assault or defend this place.

  If open-field combat was ordinary difficulty, and jungle guerrilla warfare was hard — then fighting in a vertical forest like this could only be called hell.

  Heavy cavalry would find no ground to charge; the root terrain alone would break any formation before it even reached the tree. Siege engines would fall short of their targets, and any crew that dared to advance within range would be buried by elven ranged magic before they could fire a single shot. Fire sounded tempting until you considered that a tree soaked through with a thousand years of living mana would simply redirect the flames back at you. As for magical bombardment — I looked at the heavy amber resin packed into the bark and thought: that would absorb whatever you threw at it, scatter it, dissolve it, and leave no echo behind.

  This book was originally published on Royal Road. Check it out there for the real experience.

  To storm this place by force, one would need nothing short of divine-tier power. Anything less would dissolve into endless attrition until there was nothing left to spend.

  The elven people were not the romantic creatures of legend.

  They were artists of war, who had spent a thousand years converting the passage of time into the most impenetrable defense on the continent.

  While I was still running my assessments, an army had already formed its lines before us.

  Approximately five thousand strong.

  Their ranks were immaculate. Their footsteps had been perfectly synchronized. Not one of them made a sound that wasn't necessary.

  Standing at the very front was a golden-haired male elf wearing a pure black robe and carrying a violet staff. He stood beneath the shadow cast by the roots of the Gaia World Tree, and the air around him bent subtly — the way heat rises from asphalt in midsummer, except this carried no color and no warmth, only that relentless, wordless pressure that emanated from him in steady waves.

  Every instinct I had as a mage and alchemist snapped taut at once. That isn't simply power. That is a mana cycle of immeasurable depth — seamless, without flaw — as though the entire forest breathes for him, as though the World Tree itself is an extension of his will.

  "Uncle!"

  Lilia dropped from her saddle and ran toward him.

  Of course.

  I managed a bitter smile to myself. The first move in this game had already been played — and it wasn't mine.

  The man walked Lilia back toward me and offered me a half-bow — precise in its protocol, neither servile nor dismissive.

  Behind him, five thousand elven mages bowed in unison.

  The sight carried more weight than any ceremonial welcome I had ever witnessed. Because it reminded you that every single person in that formation had every right to offer nothing at all — and had chosen, for now, to offer this.

  I returned the salute with a composure I did not entirely feel, and a faint unease settled in my chest. The elven people rarely extended such courtesies to humans. This opening gesture was a crown placed on my head without my permission — and once it was on, it would not come off easily.

  "Most esteemed Baron Marvin, I am Selven, Supreme Commander of the Holy Elven Mage Corps. On behalf of our people, and in accordance with our highest diplomatic rites, I extend to you our welcome."

  I answered with the corresponding register of imperial protocol.

  "I am Marvin Radell, representing the Wuloste Empire and the House of Radell. I convey our respects to the Holy Elven People."

  The formal exchange was long and layered — every phrase a probe, every sentence carrying weight — but it was necessary.

  It was only as the words concluded that I truly took in what stood behind Selven.

  Five thousand figures, each one robed in a different color — deep blue, crimson, silver-white, forest green — as though they had dressed themselves in the colors of the forest they called home.

  In the Empire, mages were scarce and expensive. The standard unit was fifty to a corps; the entire nation fielded no more than eighteen corps, totaling fewer than a thousand.

  What stood before me was one hundred corps.

  Five times the Empire's entire magical strength, arrayed in silence beneath the canopy of the Gaia World Tree — vast and unhurried, like the forest itself.

  If they ever chose to move as one, they could decide the outcome of a continental war.

  Selven arranged for attendants to escort my soldiers to their quarters, then personally accompanied Lilia and me onto one of the lift platforms.

  The wooden platform rose smoothly, driven by magicite, the cables drawn taut, the surface steady underfoot.

  With each meter gained, the full scale of the Gaia World Tree became both clearer and more unsettling. The bark was covered in dense carvings — runes, ancient beyond easy reading, some already buried under layers of resin, others still faintly luminous at some frequency beyond sound, as though the tree were using them to record its entire history and will. The life of the platforms grew richer as we ascended — somewhere, metal rang against metal; somewhere else, the smell of cooking drifted past; somewhere above, children ran and called out to each other across the broad boughs, utterly unconcerned with the dozens of zhang of open air beneath their feet.

  They and this tree. Long since one and the same.

  "This lift operates using natural magicite that stores sunlight," Selven explained, his tone unhurried. "The construction has held without incident."

  Lilia stood beside me and added a quiet word or two — natural in manner, but careful to avoid certain forms of address.

  She's perceptive.

  Here, the nature of what existed between us was not something to announce.

  Selven appeared not to notice. His attention was on the allied forces. He was the first to raise the subject: "Lord Marvin, I will present you to our Elder shortly — but before that, allow me to ask one question. By our calculations, the joint forces of both our peoples should have arrived within range of the Gaia Ridge yesterday. Yet as of now, there is no sign of them. This has left us at a considerable loss. I wonder if you have any thoughts on the matter?"

  "Thoughts is too generous a word," I said, watching the ground recede below us. "Only a fairly simple one. If you were Tianshu — and ten thousand Black Dragon Cavalry stationed in the Empire suddenly vanished from beneath your watch without a sound — what would your first instinct be?"

  Lilia and Selven both went still.

  Selven understood first. He let out a laugh that rang with genuine satisfaction and turned to clap me firmly on the shoulder twice. In Lilia's eyes, something lit up — she had finally grasped why I had come here with thirty riders rather than the full strength of my own forces.

  The defensive capability of this sacred ground required no debate. If twenty thousand elven troops could not hold it, adding ten or twenty thousand of my own would only produce more casualties. But with the right placement, the forces I could move and influence extended far beyond what any head count could measure.

  War has never been the addition of numbers. It is the art of positioning.

  The lift finally stopped inside a hollow formed naturally within the trunk, its walls thick enough to muffle most of the wind from outside.

  This was clearly the military core. A hundred fully armed soldiers held the corridor. Inside, a small training ground had been carved out, weapon racks lining the walls — everything arranged with an economy of purpose that left no room for anything unnecessary.

  We stepped into the inner council chamber.

  Dozens of elves were already seated along either side of the long table — expressions varied, not one of them speaking. Only the occasional sound of breathing, and beneath it, the low resonance that the World Tree itself seemed to emit, moving through the walls of the chamber in slow, steady pulses.

  Elven features ran uniformly young to human eyes. I read rank from clothing and seating position instead.

  The silver-haired elf at the head of the table held a composure that felt ancient — a stillness behind the eyes that suggested it had been cultivated across centuries rather than years. The Grand Elder, in all likelihood.

  At the far end sat several young commanders in full armor, their plate still bearing scuffs that had not been cleaned away.

  As our group entered, roughly a dozen elves rose to offer a salute. The rest remained motionless, their expressions somewhere between scrutiny and studied indifference.

  The atmosphere was wrong in a specific way — not the warmth due to an arriving ally, but the taut, loaded quiet of a confrontation that had not yet declared itself.

  I let my gaze move across the room and caught two female elves.

  One had red hair, dressed in practical close-cut attire, a longsword across her back, and eyes sharp enough to cut — she met my look directly and made no effort to conceal the wariness in it. The other had blue hair, wore a military uniform, and carried herself with a quieter quality; she had been observing me since I entered, steadily, without the hostility that surrounded her on both sides.

  Interesting.

  At the very least, the elven people were not a single unified position.

  "Elder brother. Everyone." Selven spoke first. "This is Baron Marvin — the ally the Empire has sent to fight alongside our people."

  The Grand Elder's eyes flickered with something very small and very cold. He gave me a single nod. That was the entirety of the welcome.

  I returned it with an equally cool smile.

  The reaction was immediate. Several of the young commanders at the far end pushed back their chairs with audible force, rose to their feet, and reached for their sword hilts.

  The temperature in the room dropped.

  I laughed to myself.

  Given the political position of my house, and the question of which faction had backed which candidate for the imperial succession, I had known before I ever left that this mission would not be comfortable.

  Good.

  At least what they were feeling was genuine.

  Between a politician who smiles while planning your end and a soldier who reaches for a sword — the soldier, at least, is readable. Anger can be redirected. Calculation gives you nothing to hold.

  This war had not yet formally begun.

  But the battle of words had already started.

  The elves are not just a mystical race living in trees.They are a civilization built for survival — and war.

  This chapter marks the beginning of the real alliance…and the beginning of real tension.

  As always, thank you for reading.
