The black smog, thick and suffocating, writhed from the mouths of the three collapsed patrons. It wasn't just *around* them anymore; it was *from* them, a sickening exhaust. Hester’s stomach clenched. The air grew colder, far colder than the usual Cobble-End damp, and the faint, coppery tang of burnt iron intensified. The other diners, mid-chew or mid-shove, froze, their faces a tableau of grotesque alarm. The fighting stopped. A low, guttural moan rumbled from the chest of the woman who had first convulsed, a sound more animal than human. Her silk gown, now smeared with chili oil and grime, stretched taut as her body began to distend. Her bones groaned, a sickening crunch audible even over the panicked murmurs of the crowd. [WARNING: STARVATION PLAGUE MUTATION SEVERE. IMMEDIATE THREAT: HOSTILE TRANSFORMATION.] Smoky crimson script curled above Hester’s head, urgent and sharp. It confirmed her horrifying, dawning suspicion. It wasn’t just a plague; it was a *transformation*. The flavourless, alchemical slop that the upper echelons consumed—the sterile concoctions from places like The Gilded Heron—was curdling their bodies into the very beasts that stalked the alleys. And her food… her divine, flavourful food… it wasn’t just a cure. It was a violent, agonizing withdrawal. A purge. The woman’s skin stretched thin, tearing at the elbows and knees. Her features blurred, reforming into something elongated, bestial. Her eyes, once a haughty blue, became twin pools of inky black, reflecting the flickering lantern light like obsidian shards. Her elegant coiffure dissolved into tendrils of oily black vapor that streamed from her skull. Her body swelled, then twisted, a symphony of snapping cartilage and ripping sinew, until she was no longer a woman, but a hunched, towering silhouette, a smaller, yet no less terrifying version of the Smog-Ghoul Hester had fed days prior. It still wore remnants of the silk, tattered and grotesque, clinging to its shifting, tenebrous form. A collective gasp ripped through the stunned throng. Then, a shriek. The creature, all grasping claws and hungry vapor, let out a piercing, unearthly wail that vibrated in Hester’s very bones. It lashed out, a soot-black arm sweeping aside a rickety crate of fermented bean curd with a splintering crash. Panic erupted. People screamed, shoving each other backwards, tripping over discarded bowls and fallen stools. The alley, moments ago a brawl, now became a stampede of terror. “Get back, you fools!” Bramwell Finch roared, his stained apron flapping as he tried to herd a scattering of ash-eaters away from the brute. He snatched a discarded ladle, brandishing it uselessly at the encroaching gloom. But Hester didn’t move. Her heart throbbed, not with fear, but with a fierce, protective resolve. She had seen this beast before, or a larger kin. She had cured it. And her ledger demanded satisfied patrons. This… thing… was still a patron. A *sick* patron. Her eyes fell on the steaming bamboo steamer beside her. Inside, nestled amongst fragrant pandan leaves, were the plump, perfectly formed lotus root buns she’d prepared earlier, infused with the System’s latest divine ingredient: ‘Nectar of the Verdant Bloom’. They steamed with a faint, inviting warmth. The smog-beast let out another piercing cry, its form rippling, its head cocked as if scenting fear and hunger on the breeze. Its inky gaze fixed on Hester, on the bubbling hotpot, on the very heat pouring from her stall. “No, you don’t,” Hester whispered, her voice barely audible above the din, but firm. She snatched up a bun, its soft skin warm against her palm, and despite the trembling in her hands, she moved. Not backwards, but forwards. Into the path of the lurching beast. The crowd gasped again, a horrified, unified sound. Bramwell Finch stared, mouth agape. “Hester, no! It’ll rend you limb from limb!” The creature paused, a ripple passing through its smoky mass as Hester, bracing her boots against the wet cobbles, reached up. It was taller than her, by far, its head lost in the gloom, but she aimed for where its mouth would have been, a gaping maw of shifting vapor and jagged teeth. She shoved the soft, fragrant bun right into its essence. The fiend recoiled with a violent shudder, a sound like tearing sailcloth tearing through the air. Its vaporous form convulsed, not in attack, but in raw agony. The tendrils of black smog that formed its limbs thrashed wildly, striking the air with phantom force. A pained whimper, shockingly human, escaped its form. The glowing bun, still clutched in its shadowy maw, began to radiate with an intense, calming light, pushing back against the darkness. The beast’s form began to *melt*. It wasn't disintegrating into soot; it was shrinking, reforming. The inky blackness seeped away, replaced by the faint, healthy blush of human skin. The terrifying claws receded, becoming delicate, manicured fingers. The elongated limbs shortened, the grotesque features softened. Puffs of shimmering, opaque mist rolled off its body, evaporating into the cold night air. When the mist cleared, there stood a woman. The same woman, in her tattered silk gown, but no longer a monster. She was weeping, silent, gut-wrenching sobs shaking her entire body. Her face, tear-streaked and pale, was contorted not in terror, but in a profound, devastating grief. She stumbled, clutching at her chest, her eyes wide with a dawning horror at her surroundings, at the broken crates and scattered food, at the terrified faces staring back at her. A hush fell over Cobble-End Alley, profound and absolute. The street thugs, the ash-eaters, the disguised nobles – all stood transfixed. A creature of nightmare had been turned back into a human by a single bun. [CUSTOMER SATISFACTION: 100%. STARVATION PLAGUE CURE INITIATED. NEW GOAL: EXPAND CURE TO ALL AFFECTED. REMAINING CUSTOMERS: 9,996.] The cursive script flared, burning a new directive into the air. Hester looked at the weeping woman, then at the two other unmoving figures still seeping black smog. Her goal had not been merely to survive, but to *save*. To hunt. To feed. The corrupt aristocracy, wallowing in their sterile alchemy, were not just her tormentors, but her next, most vital, patrons. Her resolve hardened, a fiery core in her timid chest. She would find them, these afflicted lords and ladies, wherever they hid. She would force-feed them her divine food, even if they clawed and bit. She would cure Tarnoch, one weeping nobleman at a time. Just as she reached for another bun, a deep, resonant rumble echoed down the alley. A sleek, black carriage, polished brass gleaming in the lamplight, drew to a halt at the mouth of Cobble-End Alley. Its doors swung open with a soft click, and from within stepped Baron Osgood Fenwick, his face a mask of frigid disdain. Behind him, a phalanx of uniformed alchemists, their brass vials glinting menacingly, fanned out, their hands already reaching for their arcane instruments. The Baron’s gaze, cold as winter ice, swept over the chaos, landing finally on Hester, standing defiant before her glowing hotpot. “Burn the witch,” Baron Fenwick ordered, his voice cutting through the silence like a shard of ice, “and her cauldron to ash.”
