The Mistwood ended like a held breath finally released.

  One moment the sapphire mist was everywhere, filtering the morning light into something dreamy and strange. The next, Akilliz stepped between two hulking silver trunks and the forest simply stopped. No gradual thinning. No transition zone. Just a hard line where ancient roots met volcanic rock and decided to go no further.

  The ground changed beneath his boots. Soft loam to sharp stone in a single step, the kind of dark glassy rock that formed when lava cooled too fast. It crunched underfoot like walking on broken pottery. The air changed too. The Mistwood's clean sweetness gave way to something acrid and mineral, the smell of hot stone and sulfur. The smell instantly reminded him of the forge back home when Pa pushed the bellows too hard and the coals went white.

  He pulled the black tome from his pack and opened it to the marked page. The map was hand drawn in faded ink, detailed enough to be useful, old enough to make him nervous. Landmarks were labeled in cramped script. The Sulfur Flats, marked with a skull and crossbones. The Steaming Traverse. The Vent Fields, where the text simply read "Here be Dragon's Breath. Harvest with extreme caution or do not harvest at all."

  The route climbed northeast from the Mistwood's edge, skirting the Sulfur Flats, ascending through a series of rocky switchbacks to the Vent Fields above. Nicodemo estimated four hours of climbing for an experienced mountaineer. Akilliz was not an experienced mountaineer. But he'd climbed Frosthelm at thirteen in a snowstorm to save his mother, and the potion was still singing in his blood making his legs feel like coiled springs.

  He started climbing.

  The slope was gentle at first. Loose scree over old lava flows, the ground dark and cracked in patterns that reminded him of dried mud in a riverbed. Heat rose through the soles of his boots in patches, warm here, cool there, no pattern he could discern. Steam leaked from fissures in thin white threads that caught the morning light and dissolved upward.

  Within an hour the gentle slope became a proper incline. The switchbacks appeared where the map said they would, carved into the rock by centuries of passage. Not a path exactly. More like a suggestion left behind by people who'd walked this way before and survived.

  The potion bubbling through his blood made the climb feel almost easy. His breathing stayed even. His legs didn't burn too bad. His mind catalogued the landscape with sharp, hungry attention, noting mineral deposits in the rock face, the specific shade of yellow where sulfur crystallized around vent openings, the way certain mosses clung to stone in places where steam kept the surface perpetually damp. Alchemy ingredients were everywhere, it was a brewer's paradise if you didn't mind the possibility of being boiled alive.

  Two hours of steady climbing passed without a hitch. The landscape shifted around him as he gained elevation, dark volcanic rock gave way to lighter stone streaked with orange and white minerals. The fissures grew wider and the steam grew thicker. Twice he had to detour around vents that belched water that seemed hot enough to raise blisters from ten feet away. He watched, wide eyed as the spray hissed on the stone and left wet stains that evaporated in seconds.

  The potion kept his heart steady through all of it. Kept his hands from shaking when a vent opened six feet to his left with a sound like a giant clearing its throat. His mind remained clinical and organized even when the ground trembled beneath him, even when a thin ribbon of orange light appeared in a crack twenty paces ahead, magma visible just below the surface. This was a place that could bite back.

  Worth noting in Nicodemo's margins. Magma flow, surface level, 200 paces above third switchback. The tome said nothing about surface magma here. Either the flows had shifted since his time or Nicodemo hadn't climbed this high.

  Neither option was comforting.

  The Sulfur Flats announced themselves before he reached them. The smell hit first, thick and sharp, the kind that burned the inside of your nose and left a metallic taste at the back of your throat. Then the color. The ground ahead turned yellow, bright sulfurous yellow, crusted and crystalline, stretching across a shallow depression maybe a hundred paces wide.

  The map said to skirt the eastern edge. Nicodemo had underlined the instruction twice and added "Do not cross. Unseen hazard." Akilliz angled east, picking his way along the depression's rim where dark rock met yellow crust.

  So far his journey had gone beautifully. Every sense remained heightened, every detail sharp. He could see the individual crystal structures in the sulfur deposits. Could hear the soft, continuous hiss of gas escaping through a thousand tiny fissures. He felt the heat radiating from the flats in waves that made the air shimmer.

  Halfway around the eastern edge, the lightheadedness started.

  Subtle at first. A faint softening at the edges of his vision, like looking through glass that hadn't been cleaned properly. He blinked it away. Kept walking. The softening came back, stronger. His thoughts, which had been running clean and fast, began to stutter. He lost the thread of what he'd been thinking about and couldn't remember what it was.

  Something was wrong.

  The potion was still active. He could feel it humming in his veins, keeping his heart rate steady, suppressing the fatigue signals his body wanted to send. But his head felt thick. Heavy. Like his skull was filling with warm water.

  Pa's old stories surfaced from somewhere deep. Tales about miners near Frosthelm's rare earth deposits. Invisible pockets of gas that pooled in low areas, heavier than air. Odorless sometimes, or masked by stronger smells. The miners called it dead air. You didn't know you were breathing it until your legs gave out and by then it was too late to climb.

  A depression. The Sulfur Flats were a bowl. Gas would pool here, invisible, settling into the lowest ground like water filling a basin.

  The potion had masked the early symptoms. No headache warning. No nausea warning. No racing pulse to tell him his blood was starving for oxygen. It had suppressed every signal his body tried to send.

  He turned uphill and climbed.

  His legs moved but the ground seemed to stretch ahead of him, the slope growing steeper with every step. His vision narrowed to a tunnel. The yellow crust blurred into the dark rock and both blurred into each other until the world was just shapes and the shapes were melting.

  He fell. Hands on stone. Hot stone. The heat jolted through his palms and into his brain like a slap and for one sharp moment everything was clear again. He pushed himself up and climbed. Hand over hand on the rock face, abandoning the path, just going up because up was away from the gas and away from the gas was alive.

  Ten feet. Twenty. Thirty.

  The air changed, he felt it in his lungs first. It came with sudden richness, like surfacing from deep water. Oxygen now flooding back in, his vision snapped wide. The tunnel collapsed outward and the world returned in a rush of color and sound. He was on his hands and knees on a rock ledge above the Sulfur Flats, gasping, his heart finally hammering the way it should have been for the last five minutes.

  The potion had nearly killed him. Not by failing. By succeeding, doing exactly what it was designed to do, which was suppress every distress signal his body produced. In a place where distress signals meant the difference between climbing to safety and lying down in poison air and never getting up.

  He sat on the ledge for a long time after his breathing steadied. Looking down at the yellow flats below, they looked peaceful from here. Warm and bright and completely lethal.

  The thing keeping me going is also the thing that's going to kill me.

  He wasn't sure if the thought was about the potion or about Taimon. Maybe there wasn't a difference anymore.

  The Vent Fields were beautiful in the way that dangerous things often are.

  The ground here was fractured into a maze of cracks and fissures, some narrow enough to step over, others wide enough to swallow a person whole. Steam rose from the deeper ones in thick columns that climbed thirty, forty, fifty feet before the wind sheared them apart. The rock between the fissures glowed from beneath, orange and red light bleeding up through the stone like veins of fire in the mountain's skin.

  And there, growing from the edges of the largest vents where superheated air met the cold mountain atmosphere, were the Dragon's Breath plants.

  Extraordinary.

  Deep red stems thick as his thumb, rising from cracks in the rock where no other living thing could survive. Their leaves were dark, almost black, edged with a fine shimmer of gold that caught the steam's diffused light. And the flowers, each plant bore a single flower at its apex, a tight complex bloom of overlapping petals that shimmered with visible heat. The air around them distorted and bent, the way air bent above a forge. Looking directly at the flowers was like looking at something through running water.

  Seven plants in the immediate area. Three were small, still growing, their stems barely a finger's width. Two were large but positioned over vents too active to approach, steam blasting upward in irregular bursts that would scald flesh to the bone. Two were accessible. Mature specimens growing from the lip of a wide, relatively stable fissure where the steam rose in a gentle, continuous curtain rather than violent eruptions.

  He chose the larger of the two accessible plants and set down his pack on stable ground.

  Time to work.

  The tome's harvesting instructions were specific. The plant must be cut at the base with a clean blade, the cut made in a single motion. Once severed, the volatile compounds in the stem would begin to react with open air. The alchemist had approximately three seconds to transfer the cut plant into a treated vessel. Vessels must be lined with fire ash and sealed promptly. Failure to seal within the reaction window would result in ignition. Nicodemo noted, almost casually, that three of his colleagues had died learning this.

  But first, Soul's Breath.

  This story has been taken without authorization. Report any sightings.

  A flat section of stone became his workstation. He laid out supplies with methodical care. Mortar. Pestle. The three vials of Mistwood dew, their sapphire light steady and clean against the volcanic rock's angry glow. Base tincture. Dried Vyr'elthar leaves, their silver veins still visible even crumbled. A pinch of chamomile and feverfew, and the last of his dried moonflower petals. His smallest copper pot balanced on a ring of stones over a natural heat vent that provided steady, controllable warmth.

  The recipe lived in his bones, the same one he refined in Eryndor's hut and perfected across several attempts. Soul's Breath wasn't just a potion. It was a prayer made liquid. Every step was an act of faith.

  Mistwood dew went in first, poured in slow deliberate spirals, the beads merging alive in the copper pot. The sapphire liquid caught the volcanic glow from below and threw pale blue light across his hands. One corrupted. One burned. Neither what they'd been a month ago.

  The Vyr'elthar came next, ground coarse. Two generous pinches for raw strength, the silver veins releasing their sharp, piney bite as the leaves broke apart under the pestle. Feverfew followed, to cut illness at its core, the way Eryndor had taught him. The powder went in direct, stirred slowly until it dissolved.

  Lower the pot closer to the vent's heat. Not touching the stone. Hovering. Counting breaths the way the old elf had shown him. Slow and even. A faint blue flickered at the edges of the liquid, tentative but alive.

  Raise it smoothly. Crumble the moonflower petals in carefully, their dust catching the light like golden snow. Then chamomile to soothe the bind, just a pinch, barely enough to taste. The mixture held. No curdling. No grey. The blue deepened, swirling richer, and the pot went down again for a final count of twenty breaths.

  Then he hummed.

  Ma's three note tune. The one that made plants grow and potions true. The notes rose from his chest and filled the Vent Fields like a forbidden tune. The steam seemed to lean toward him. The Dragon's Breath flowers pulsed in their heated shimmer, as if responding to a frequency they recognized.

  No demon guided his hands. No borrowed knowledge shaped the work. Just the simple art of watching, learning and failing only to try again. He read the liquid's surface tension, feeling the exact moment the mixture wanted to turn. Adjusting by pure instinct. Carefully, he began pouring a thread of base tincture in three measures, stirring counterclockwise with a glass rod. The liquid shifted and began its climb toward that sapphire star color.

  It came gradually, not the violent surge of a forced reaction but the slow, steady brightening of something finding its true form. Silver streaks warming to ocean blue. The whole pot glowed with a light that had nothing to do with the volcanic vent beneath it.

  Sapphire. True sapphire, luminous and alive. The potion still surprised him, humming in perfect rhythm with his breath. Stars flickered faint within the depths, the way they had in Eryndor's hut the first time he'd gotten it right. The deep blue had become something else entirely. Something that smelled like the air at the peak of Frosthelm before dawn, clean and pure and touched with something he had no word for.

  Into his cleanest vial it went. He held it up against the sky. The light inside was steady. Pure. No thinning. No fading. The essence held.

  A perfect brew.

  The first measure tasted the way it always did. Fresh mountain water, cool and perfect, with a faint sweetness like spring honey and morning dew. Warmth spread through him like an embrace, healing the small hurts he'd collected on the climb. The scrapes on his palms sealed shut. The ache in his lungs from the sulfur gas dissolved like mist. The deep, bone level exhaustion that the acceleration potion had been plastering over for hours eased back, just enough to remind him what it felt like to be whole.

  His left arm didn't change. The corruption sat unmoved beneath gray skin, black veins pulsing their own rhythm. The potion couldn't undo what was chosen. He'd learned that lesson already.

  He closed his eyes and for one moment he was in Ma's kitchen. Could smell the cinnamon and hear her humming, he swore he could feel the sunlight on his face.

  Then he opened his eyes and he was alone on a volcanic mountain with a demon in his chest and a harvest that could kill him.

  But the potion was perfect and he'd made it himself.

  The treated vial took careful preparation according to the tome's specifications. The interior needed a fire ash lining to prevent the volatile compounds from reacting with bare glass. Volcanic ash scraped from the fissure's edge, mixed with a measure of binding agent, worked into a thin paste with a few drops of base tincture. He poured the paste into the vial and rolled it slowly between his palms, tilting and rotating until the mixture coated the interior walls in an even layer. Over the heat vent to cure, turning steady, watching the paste harden from wet gray to dry black. When it was done the vial's interior was rough and dark, lined with a thin shell that would absorb the plant's initial heat burst instead of letting it reach the glass.

  Fragile. One hard knock would crack the lining and ruin the seal. But it would hold long enough if he was careful.

  The steam vent's cycles needed timing. Every four minutes, or about 75 counted breaths, the gentle curtain of steam intensified into a harder blast that lasted roughly thirty seconds before settling back. He'd need to approach during the calm phase and complete the harvest before the next blast.

  Four minutes. Cut, transfer, seal. Three seconds between cut and ignition.

  Two more cycles passed while he watched, confirming the pattern. Consistent. Four minutes of calm. Thirty seconds of blast. The heat during the calm phase was intense but bearable if he moved quickly.

  The blast phase ended. The steam settled to its gentle curtain.

  He moved.

  The heat hit him three feet from the plant. Dry and enormous, like stepping into the mouth of a furnace. He could feel his hair curling and his skin tightening. The moisture in his eyes was evaporating faster than his body could replace it. He squinted against it and reached for the plant.

  His left hand, the corrupted one, touched the stem first. Something registered through the pain and the urgency. The heat didn't bother the gray skin. His right hand, hovering near the flower, was screaming with heat. The left felt warm. Almost comfortable. The corruption was insulating him somehow.

  A grip on the stem with his left hand. The knife came up with his right. Clean cut. Single motion.

  The stem severed clean. The volatile reaction began immediately, a faint hiss as the cut surface met open air. Three seconds.

  He reached for the treated vial with his right hand.

  The ground shook.

  Not the gentle tremor he'd felt during the climb. A sudden, violent lurch that shifted the rock beneath his feet and sent loose stones clattering into the fissure. A geyser erupted forty feet to his south, a column of boiling water and steam that shot into the sky with a sound like a cannon. The shockwave hit him sideways.

  His hand slipped.

  The cut stem tilted in his grip. The volatile compounds caught air for too long, just a fraction of a second too long, and the reaction went critical. The flower ignited with a sharp pop and a burst of heat that seared his right hand from palm to fingertips.

  He dropped the burning stem and threw himself backward screaming. The plant hit the ground and flared, a brief, intense blaze of red and gold that consumed the specimen in seconds, leaving nothing but a black scorch mark and the smell of something chemical and acrid.

  His right hand.

  Cradled against his chest. The skin across his palm and fingers was bright red, already blistering. The pain arrived a moment later, a deep, throbbing burn that radiated up his wrist and made his vision pulse white at the edges. His good hand. His brewing hand.

  He sat down hard on the volcanic rock and quickly drank the Soul's Breath. The sapphire liquid did its work immediately. Pain eased. Blisters stopped spreading, then reversed. New skin formed, pink and whole, the burn retreating as if it had never been. Within a minute the hand looked normal again. Healed.

  The scorch mark where the Dragon's Breath specimen had been told the rest of the story. One attempt gone. One precious vial cracked from the concussive blast. Enough supplies for one more vial. One more try.

  The math was not comforting.

  One treated vial's worth of materials left. One accessible Dragon's Breath specimen. Worse, the sun was past its peak now, sliding toward the western ridgeline. At least six hours on the mountain already.

  He was supposed to be heading back by now, descending with his harvest, walking through Luminael's gate by tomorrow morning. Instead he was sitting on volcanic rock with one attempt left and the understanding settling into him like cold water, that this was not going to be the quick trip he'd promised Sylvara.

  The second treated vial needed making. The approach needed perfect timing. The harvest needed flawless execution, the specimen sealed before ignition.

  And he needed to sleep.

  His body was telling him in every way it knew how. The acceleration potion was suppressing the worst of it but underneath the chemical wall, exhaustion was building like water behind a dam. The human body wasn't built for this. The potion couldn't change that. It could only delay the reckoning.

  The spheres in his pack caught his eye. Each one contained a promise and a poison. If he took one now it would buy him the clarity to prepare the vial and attempt the harvest.

  But the sulfur gas had nearly killed him because the potion hid the warning signs. The hand burn had happened because the geyser caught him in a moment of chemical overconfidence.

  Pattern recognition. Ma's voice in his head. When the same mistake shows up twice, Aki, it's not bad luck. It's a lesson you haven't learned yet.

  The sphere went back in the pack.

  He would prepare the vial without acceleration. Slowly. Carefully. Feeling every ache and limitation so he knew exactly what he could and couldn't do. And then he would rest. Not sleep. He would not sleep on this mountain. But he would sit, and eat what remained of his rations, and let his body recover what it could before the attempt.

  Night was coming. The temperature was already dropping as the sun sank below the ridgeline. But the volcanic vents kept the immediate area warm, a strange pocket of heat in the freezing mountain air. Steam rose all around him in columns that caught the dying light and turned pink, then orange, then red as the sky darkened.

  The last of his dried rations went quickly. Water he drank sparingly, the supply lower than he'd like. The volcanic slopes had no clean water sources. Everything was mineral heavy, sulfur tainted, unsafe to drink without treatment he didn't have time to perform.

  The second treated vial took shape by the light of his bottled flame and the ambient glow of magma seeping through cracks in the rock beneath him. Slow work. Careful work. Testing his hand's grip on the mortar, on the glass rod, on the knife. Thumb pressed firm. Fingers held steady. The Soul's Breath had done its job.

  Night deepened around him. The Vent Fields transformed. Magma flows that had been invisible in daylight became bright rivers of orange light, threading through the cracks like the mountain's circulatory system laid bare. Geysers erupted at intervals, their steam columns catching the glow from below and turning into pillars of amber and gold. The Dragon's Breath flowers pulsed in their heated shimmer, their petals almost luminous against the dark.

  Hellishly beautiful.

  He sat alone in the middle of it, a workstation spread across volcanic rock, bottled flame for light, the mountain's breath for warmth, and thought about Nicodemo's passage on solo harvesting. The old alchemists had worked in pairs. One to cut, one to seal. The volatile window was too narrow for a single person to do both safely. Nicodemo's method for solo harvest involved a clamp mechanism that held the treated vial at the stem's base so the plant dropped directly into the vessel when cut.

  No clamp. Not the materials to build one properly.

  But he had climbing rope. He had the cracked vial's metal seal ring, which was the right diameter to grip a stem. He had cord and a steady left hand and a brain that had spent time learning to make something from nothing in Sylvara's workshop.

  He started building.

  The rig was crude. A loop of climbing cord around the treated vial, cinched tight. The metal ring attached to the cord's end, bent into an open clamp that could grip the stem just above the cut point. The whole assembly was designed to hang from the plant itself so that when the stem was severed, the weight of the cut section would pull it downward directly into the vial's mouth.

  Gravity as an assistant. Not elegant. But physics didn't care about elegance.

  The first test used a dead stem he'd found near the scorch mark. Hung it. Made the cut. The stem dropped into the vial's mouth with a satisfying clink. Not perfectly centered. But inside.

  Six more tests followed. Adjusted the cord length. Widened the clamp. By the seventh, the stem dropped true every time.

  He sat back. Looked at the rig in his hands. Ugly. Functional. Built from scraps and ingenuity and the kind of stubborn refusal to die that Ma had always said was his best and worst quality.

  No demon. No borrowed knowledge. Just a boy who'd learned to brew with nothing and make something from less.

  Dawn was coming. The eastern sky shifted from black to gray. The mountain's magma glow faded as ambient light crept back in. The Dragon's Breath flowers were still there, pulsing in their heat shimmer, waiting.

  One final check. Treated vial, prepared and lined. Harvesting rig, tested. Knife, sharpened on volcanic stone until it sang. Soul's Breath, and plenty of acceleration spheres.

  His right hand tingled faintly. His left arm pulsed with the mountain's heartbeat. His body ached with the accumulated weight of days without proper sleep.

  One attempt. One specimen. One chance.

  He stood. Picked up his rig. And walked toward the remaining Dragon's Breath.
