The bell above Jakob's door clanged as Caleb stepped inside. The festival's chaos had bled out of Deadfall overnight, and the steady buzz of morning commerce was slowly returning.
"Master Caldorn!" Jakob boomed across the shop before Caleb had taken three steps. The merchant set down his abacus and swept his arms wide.
"The prodigy returns! Tell me, my friend, how does it feel to have the entire town chattering about your glorious—" Caleb reached the counter and placed three E-tier spirit stones on the polished wood.
"Ahhhh, to business then!" Jakob scooped the stones into his palm. His examination lasted only a heartbeat.
"Three E-tier stones, eh? Part of the tournament purse?" Jakob dropped them into a reinforced box beneath the counter and then started pulling out payment.
"Market rate is twenty per stone." Caleb wasn't in the mood to haggle this morning.
"Works for me, Jakob. Thanks." He counted out sixty gold coins, forming three neat stacks. Jakob set down the last stack and kept the coins on his side of the counter, leaning forward.
"Now, before we settle the betting account, let me tell you about a once-in-a-lifetime investment opportunity I have in the back. Premium F-tier armor, Caldorn. Not the mass-produced rubbish from the Mirathra, but artisan work. Yorrin's Forge quality, practically—""Jakob."
"—stolen at the price I'm offering, truly—""The betting payout." Jakob stopped, straightened, and slid the sixty gold across the counter.
"Yes, yes. Very good!" Caleb swept the coins into his pouch and Jakob pulled a thick leather ledger from below the counter. He flipped through the pages quickly, his fingers tracking entries only he could understand.
"Now then." Jakob tapped the page.
"Let's discuss the main event." He ran his index finger down a column, eyes scanning the cramped handwriting.
"Your initial bet of three gold was against Finn Babin, with three-to-one odds." He moved to the next entry.
"After winning that your pot advanced to twelve gold." Caleb watched Jakob, ignoring the ledger.
"You let it ride against Morian Greenshade, but the odds dropped significantly after you revealed your strength." He turned a page.
"Then Narbok Blackbriar and the final day." Jakob hesitated.
"This is where I honestly thought you'd cash out. You had enough gold at that point to buy another essence stone when you visited me yesterday. It would have been a solid boost to a key attribute that could have helped you advance!" Caleb shrugged.
"One stone wasn't enough."
"Oh?"
"One of the nobles was after Narbok… there's no way one stone would have bridged the gap between us. If I was going to beat any of them through attributes alone I needed more than marginal gains."
"So you demonstrated fiscal discipline!" Jakob spread his hands wide, swelling with performative grandeur.
"A rare and beautiful trait in the modern adventurer! You resisted the siren song of immediate gratification in favor of—""Growing the pot, yes," Caleb interrupted.
"I needed the big payout from the noble upset more than I needed incremental power. It was about compounding my investment." Jakob stilled, and the frenetic energy vanished. He settled his hands on the counter as he studied Caleb, and when he spoke again, his voice was quiet.
"You… actually understand it. Most people, adventurers in particular, see gold as something to spend. Easy come, easy go. A means to an end. But you saw the tournament as a financial instrument. The fights were just... variables in an equation?"
"The fights were a bit more than that, Jakob. The bleeding wasn't exactly fake. But yeah, I made sure to gain as much from my troubles as I could." Jakob smiled slowly, a knowing look in his eyes.
"Greedy," Jakob nodded sagely." Calculated. I approve." The merchant skipped to the final page.
"And then we have the championship match against Astrin Kaelix. You had accumulated one hundred gold after the Narbok and Rielle wins… So what's he do? He leaves instructions to bet the entire stack on your opponent to win!" Jakob guffawed good-naturedly.
"You changed the bet that you'd win out in the end." Jakob peered at Caleb.
"Why? What happened to all of that confidence?" Caleb shrugged.
"It was really the only play that made sense." Jakob arched an eyebrow while Caleb organized his thoughts, pulling together the thoughts that had governed his decision yesterday morning.
"There were two possible outcomes, right?" He held up one finger.
"In the first scenario, I win out. If that happens I get the grand prize, which is essence stones worth hundreds of gold. The betting pot becomes less important in that scenario, relative to my pre-tournament position." He raised a second finger.
"The other option was that I lose somewhere along the way. Which was the more likely outcome, if we're being honest. And in that case, depending on when I lost I may not have collected any rewards from the podium, and I would have given up all the gold I'd won betting until that point. So I made the decision to change the bet, with you putting the money on me against Rielle, but putting it on Kasien or Astrin if and when I faced one of them. Lady Draha was the only one I realistically had any chance of beating.
For the others, the betting became compensation for the loss I was expecting. Not that I didn't try my hardest; a man has to have his pride, after all." Jakob could only stare at him, dumbstruck.
"It was insurance," Caleb continued.
"If I'd lost, I needed capital to recover. Betting against myself guaranteed I wouldn't walk away empty-handed either way."
"You hedged your own championship match." Jakob shook his head slowly.
"Most fighters would call that defeatist."
"Most fighters don't beat nobles in duels." Jakob barked an honest laugh.
"Businessman to businessman, Caldorn, I respect the strategy! Truly. But I'll have you know, watching you cost me sleep. I had twenty percent on the line, after all!" Jakob unlocked the strongbox again and counted out the winnings.
"In total, you managed to earn one hundred and twenty gold. Not a bad haul after four days work, eh?" He slid twenty-five gold apart and kept it on his side of the counter.
"My cut, plus a modest handling fee for the emotional distress you inflicted upon me. You understand." The remaining ninety-five gold coins formed a substantial pile. Jakob pushed them across the counter, clutching his chest as if the act physically pained him. Caleb could only laugh at the man's theatrics as he pulled the coins toward himself. Combined with the sixty from the stones, he now had one hundred fifty-five gold. By any reasonable measure, this pile represented a fortune.
Against The Sovereign Path's demands, however; it was little more than lunch money. Jakob watched him carefully.
"My friend! Why do you look so dejected after scooping up that pile of gold?"
"Just putting things in perspective, Jakob."
"Well." Jakob leaned forward, unable to help himself.
"A heavy purse needs a heavy investment. I have several premium opportunities that—" Caleb raised one palm.
"Not today, Jakob. I have a date with an alchemist."
"Aurelian Veil?"
"The same."
"My condolences, then." Jakob made a warding gesture with a hand.
"May your patience be infinite and your tolerance for condescension vast." Caleb laughed and turned toward the door. The walk to The Golden Mortar took little time. When Caleb opened the front door he found Selara standing behind the counter, arms crossed. She skipped the pleasantries. The story has been illicitly taken; should you find it on Amazon, report the infringement.
"You're late." Caleb glanced at the position of Aurum through the shop's small windows.
"I don't recall us setting a specific time."
"I told you to 'come tomorrow.' For someone who is supposed to be my apprentice you should have inferred 'first thing in the morning.'" She gestured toward the back.
"He is waiting in the archive." She came around the counter, leading him past the barren public shelves and into the laboratory. They passed through the reinforced door into the main storeroom and across to the archive. Selara shoved the door open, and the place was exactly as Caleb remembered it from before the tournament. A cramped, cluttered room that felt more like a hoarder's den than a professional's cache. Shelves climbed from floor to ceiling, overflowing with jars, vials, and boxes.
Aurelian was already there, leaning against a stack of crates with his arms folded. His silver-blond hair was tied back in a severe ponytail, and he tracked Caleb's entrance intently.
"Sit." Selara pointed to the chair. Caleb did, the rickety seat creaking beneath him. Selara pulled a thin volume from the piled books, Ecological Dynamics of Spirit Beast Territories, and opened it to a marked page.
"Chapter Seven: Symbiotic Relationships Between Spirit Beasts and Natural Treasures. Explain the three-tier classification system." [Savant of the Mind] supplied the information instantly. He explained the differences between parasitic, commensal, and mutualistic relationships. He provided examples from the text, cross-referenced concepts from the other volumes she'd assigned, and drew logical connections between ecosystem stability and harvesting ethics. Selara nodded, flipping to another section.
"Chapter Twelve: Identifying Contaminated Spirit Herbs. What are the four primary indicators?" Caleb answered. Discoloration patterns, abnormal resonance frequencies, structural degradation, and the presence of foreign spiritual signatures. He elaborated on each, describing the specific manifestations and their implications for alchemical purity. Question after question. Chapter after chapter. Caleb answered them all flawlessly. After what felt like hours, Selara finally closed the last book.
She rested her hand on the stack of leather-bound tomes, looking between them and Caleb while shaking her head in disbelief.
"I gave you these books less than a month ago…" She turned to her brother, smiling victoriously.
"He has not missed a single detail, Aurelian. Not one. It is—""Oh spare me, Selara." Aurelian pushed off the crates.
"Reciting facts is not alchemy. A parrot can recite a recipe; it cannot cook." Selara paused mid-sentence, turning to her brother.
"But he has answered every—""He has memorized text. That proves he can read, not that he can think." He shifted his full attention to Caleb.
"Time for a practical test, boy. Identify the most potent healing agent currently in this room." Caleb adjusted on the chair. He recognized this game: the sudden pivot designed to expose inexperience.
"Define 'potent,' Aurelian. Are we talking pure resonance? Speed of tissue regeneration? Market value? Shelf stability?" Aurelian's eye twitched.
"Do not mince words with me. Which concoction is the best? If you cannot feel it, then you are spiritually blind. An alchemist must have impeccable [Spiritual Perception] or we will just be wasting our time." Caleb stood, turning slowly to survey the room. He activated his perception and allowed the overlapping auras to filter through his awareness. The archive contained hundreds of items. Several sealed vials on the main shelf emitted the distinctive fresh green signatures of nature-based healing potions.
He focused on those vials. Three of them glowed with what his [Spiritual Analysis] identified as "vibrant" resonance. They were superior-grade healing potions, their energies beating with strong, clear frequencies, carrying the robust auras of true craftsmanship. Those are the obvious answers, Foster. Aurelian wouldn't ask an obvious question… where is it… Caleb recalled something from his first visit here and concentrated on a specific spot in the room.
Top shelf, back corner, partially obscured by a crate labeled "nightshade derivatives." In his memory, there had been a dusty vial there. Small and unremarkable, with a handwritten label: Tears of Renewal. The liquid inside had glowed with a faint white light, and its spiritual resonance had been extraordinary, only matched by Selara's Flamewright. He compared the memory to the present reality. The spot was empty. The crate remained, and the surrounding jars were unchanged.
But the space where the vial had rested was conspicuously vacant, a clean outline in the dust marking where it had been removed. Caleb turned to face Aurelian and raised one hand, pointing at the vacant spot on the top shelf.
"It's not here." Aurelian's haughty gaze froze on his face as his eyes started to widen.
"There are plenty of healing potions on these shelves that I would deem adequate, some are even exceptional," Caleb continued, lowering his hand.
"But they're trash compared to the Tears of Renewal that was hidden behind that crate two weeks ago." He smiled at Aurelian's stunned stare, enjoying every moment of the man's comeuppance.
"That was the best one." Selara couldn't contain herself any longer, and the laughter she'd been trying to suppress started to wheeze out of her as she watched her brother. Aurelian just stared at Caleb, then at the shelf, then back at Caleb. His mouth opened, closed, and opened again. So that's what it means when someone looks like 'a fish out of water.' Ha!
"Y-you saw that?" Aurelian finally asked.
"On your first day in this room? And you just… left such a masterpiece there?"
"It was hard to miss," Caleb shrugged.
"And while I won't say I didn't touch it, I made sure to put it back where I found it." Caleb narrowed his eyes at the man.
"However, I don't know that I like what you're insinuating…"
"Don't take any offense, Thalorin, he's just projecting," Selara giggled.
"Aurelian would have stolen such a treasure in a heartbeat, given half the chance." Her brother could only splutter in response.
"I-I… you, you, you… bah!" Caleb finally relented and extended the olive branch.
"Will you tell me about it, Aurelian? I've not felt anything like it since." The alchemist took several moments to collect himself before moving to the shelf in question and staring at the where the potion had been. As if it held secrets. When he finally spoke, he was quiet; his usual condescension had evaporated and was replaced by something else.
"Did you know that all healing potions on the market operate on a principle called accelerated regeneration? They force the body's natural healing processes into overdrive. What they do not do is create materia. They merely redistribute what the body has available. The materia to knit flesh and rebuild bone all must come from somewhere…" Caleb went still.
The realization triggered a cascade of connections: the ravenous hunger after healing from the goblin matriarch's wounds, the Vitality rations he was forced to consume after the tournament.
"A healthy patient can afford the expenditure, depending on the injury. But a critically injured person, someone whose Vitality is already depleted? Or who has lost too much body mass?" He turned toward Caleb.
"A healing potion could kill them. It might force their body to consume itself beyond viability." So potions don't heal me on their own? They force my body to eat itself to survive? A dark joke surfaced in his thoughts. Self-harm followed by healing potions: the world's worst diet plan. He caught himself. Okay, that's a little much, Foster. Aurelian pulled Caleb back to the present.
"The Tears of Renewal are different, boy, and that is why they are special. They violate the law of equivalent exchange."
"Should I… know what that means?"
"It means that the potion itself creates materia to sustain the healing." Aurelian's eyes burned with fanatical intensity.
"New flesh. New bone. New blood and viscera. The patient's Vitality remains untouched. The healing is additive, not redistributive - a true miracle of magic." He walked to the worktable. Picking up a blank piece of parchment, he began sketching a diagram: circles representing energy flows, arrows indicating transformations.
"Every alchemist dreams of circumventing equivalent exchange, of transmuting base substances into something greater with magic alone. To create gold from lead. To generate life from inert materia. It is the pinnacle of alchemy, and the proof of ultimate mastery." He tapped the drawing.
"The Tears are one such example that proves it is possible. Someone, somewhere, discovered how to break the fundamental law and create that potion. And they left no record of the process…"
"You're trying to reverse-engineer it, aren't you?"
"For over ten years. That vial is my obsession, my life's work. If I can replicate the formula, if I could just understand the mechanism… I will have accomplished something no independent alchemist has in centuries." The room fell quiet. Caleb studied the layout Aurelian's drawing, [Savant of the Mind] analyzing the structure. The arrows formed a closed loop, a self-sustaining reaction that generated more than it consumed. Thermodynamically impossible in his old world.
But here, in a universe governed by spiritual energy and magic? Who knew. Aurelian straightened. He crossed his arms, regarding Caleb with grudging respect.
"You have eyes and a brain, I will admit." The words felt like they cost the alchemist something.
"Acute spiritual perception combined with actual intelligence. That is… acceptable." He waved his hand over the table, and three books materialized in a stack out of thin air. Each one was thick, the spines reinforced with metal clasps. The titles read Basic Spells for the Aspiring Alchemist, books one through three. Aurelian patted the top volume.
"These grimoires will instruct you on how to cast the foundational Spells to conduct alchemy; Spells every true alchemist must master." He met Caleb's eyes.
"Once you can cast all of them sufficiently, then you will be my apprentice. Until that moment, you are merely a hopeful." Caleb reached for the top book. Finally! Real magic! Soon they'll be saying, 'you're a wizard, Caleb!' He opened the cover. The first page contained an index of Spells, organized by complexity. Each entry included diagrams of runic structures and instructions for how to apply your Intent. Caleb glanced up hesitantly, remembering something that made him hold back.
"Felicity told me grimoires like these cost a fortune. Are… are you sure I can just… use them?" Aurelian brushed the question aside with a wave of his hand.
"Do not stress over such trivialities. Use them at your leisure, but they do not leave the archive." He turned toward the door.
"You will practice here until I am satisfied you won't accidentally immolate yourself or damage my laboratory." He stopped in the doorway.
"And boy? Do not disappoint me. I have invested significant time in this evaluation. I expect returns." He left then, his footsteps quickly receding into the storage room beyond. Selara remained, propped against the shelves. She watched Caleb with quiet amusement dancing in her eyes.
"I think he likes you." Caleb blinked.
"That was approval?"
"For Aurelian? Yes," She smiled.
"He only threatens people he believes have potential. Everyone else… he just dismisses and does not waste the time." Caleb looked down at the grimoires. Three priceless volumes, each one packed with knowledge that couldn't even be purchased on the open market. Aurelian had handed them over as if they were loaners from a library. He thought about the Tears of Renewal, a masterwork creation hidden on a dusty shelf. Selara's legendary sword, Flamewright, casually stored in a void ring of all things.
Who are these people? Two exiled nobles, operating out of a frontier backwater and carrying around priceless resources like it was the most natural thing in the world. Their expertise was undeniable, and their wealth staggering. But their presence here made no sense to him. What are they doing in Deadfall? Selara eased away from the shelves, moving toward the door. At the threshold, she paused and glanced back with an amused, knowing look.
"The foraging can wait, Thalorin. Right now, you have Spells to learn." She left, closing the door behind her. Caleb sat alone in the archive, surrounded by the Veil's diverse assortment of books and reagents. He took up the first grimoire, flipping past the index to the initial Spell's chapter. [Thermal Manipulation] - A Primer on Heat Control. The text began with a diagram. A hand, palm up, with a three-rune construct floating in the air above it. Caleb leaned forward, devouring the instructions.
He forced the mystery of the Veils out of his mind. Right now, he was finally going to learn magic.
