The city of Aurealis was unraveling. From the highest ivory spires of the magistrates' quarter to the narrow alleys of the merchant district, the smothering pall of the Fog had become inescapable. Every breath was suspect. Every shadow carried threat. Children no longer played in the courtyards; the laughter of the city was replaced by coughing fits and wailing cries.
Lysander stood at the edge of the eastern ward, coat torn, mask tight against his face. His hands were raw from endless sutures and herbal concoctions. Behind him, dozens of patients lined the hastily built triage tents. Their eyes, fever-bright, followed him like the gaze of a congregation before an unwilling prophet.
"Doctor," said Elira, her voice sharp with fatigue. "The infection isn't spreading randomly anymore. It's coordinated. Look." She unfurled a bloodstained parchment. On it, crude charcoal lines mapped the city. Red marks showed outbreaks: the infirmaries, the food warehouses, the mage guild's archive. The pattern was unmistakable.
"They're hitting supply chains," Lysander whispered, pulse quickening. "It's deliberate."
The Fog had adapted.
The morning had begun with a tremor of false hope. For three days, the curve of infections had seemed to flatten. Lysander almost dared to think their countermeasures—distillations of silverwort, binding runes to filter lungs, strict quarantine—had turned the tide. But then came the first wave.
At dawn, a surge of patients flooded the tents, coughing black mist. They were not the frail and elderly this time, but city guards, strong men and women who had been stationed at choke points. Their armor was cracked, their veins blackened as though ink itself had invaded them.
"They're taking down the watchmen," muttered Captain Roran, sweat running down his temples as he tried to hold the line outside. "They knew where to strike."
Lysander bent over one guard whose pulse was flickering like a candle. The man's breath rattled, and with each exhale, a thread of Fog seeped from his mouth. Lysander pressed a ward-stone against his chest. The glow resisted, then shattered.
"Elira!" Lysander barked. "Stabilize him with a silverwort infusion. Use the concentrated tincture, not the diluted one."
"That will damage his liver!"
"He won't live long enough for that to matter."
The tent filled with the smell of herbs and blood. All around, the healers scrambled like ants, but for every one they stabilized, two more collapsed.
By nightfall, the second wave struck. This time it was not guards, but the apprentices of the guild. Mages who had spent weeks weaving protective barriers were carried in, eyes clouded, their tongues whispering words not their own.
"They've breached the guild wards," Elira said, fury sparking in her tone. "Do you see? The Fog doesn't just infect flesh—it's learning spells."
Lysander's blood chilled. He watched as a young mage convulsed, arcane symbols flashing across her skin. The infection had memorized fragments of incantations and was replaying them like a mockery. The Fog was not only a sickness. It was a strategist.
"How do you fight something that studies you?" whispered one healer.
"With deception," Lysander replied, though the words tasted like ash.
Three days later, Aurealis was on the brink. Food stores were quarantined, the guild wards flickering like candlelight, and the Council of Nobles had begun to whisper of abandoning the city altogether.
In the triage tents, Lysander caught his own reflection in a basin of water. His eyes were sunken, his once-steady surgeon's hands trembling. He remembered operating theaters in his old world, the soft hum of machines, the sterile smell of antiseptic. Now there was only chaos, herbs, and runes scratched in desperation.
Elira entered, dragging a wounded courier. The boy clutched a scroll sealed with crimson wax. "From the northern outpost," Elira explained.
Lysander broke the seal. The message was short and damning: The Fog is moving in coordinated waves. It is no longer following weather or terrain. It is choosing targets. A second note, scrawled in haste, chilled him further: It knows about you.
That night, Lysander gathered his small circle of allies: Elira, Captain Roran, two surviving guild scholars, and a handful of exhausted healers.
"The Fog is adapting to every cure we develop," he began, voice low but steady. "We can't keep patching wounds while it outthinks us. We must turn its own intelligence against it."
The room buzzed with disbelief.
"You want to trick the Fog?" one scholar scoffed. "It's not a child chasing after sweets."
"No," Lysander said. "It's a predator. And predators follow bait." He unrolled a fresh map of Aurealis, drawing marks in black ink. "We'll set up decoy signals—both magical and medical. False quarantine sites, false energy signatures. We'll lure it away from the true supply chains."
Roran frowned. "And when it attacks the decoys?"
"Then we strike back, hard and coordinated. We give it nothing real to learn from."
Elira leaned forward, her eyes gleaming with dangerous resolve. "A war of misdirection."
Two nights later, the trap was sprung. At the abandoned western ward, Lysander's team lit false ward-stones and scattered herbs designed to mimic the smell of infected tissue. From the rooftops, guild mages projected faint illusions of healers at work.
The Fog came.
A wall of grey rolled through the streets like a sentient tide. It hissed against the cobblestones, drawn by the false signals. Within minutes, tendrils lashed at the phantom healers, tearing through empty air.
"Now!" Lysander cried.
Archers released bolts tipped with silverwort resin. Mages unleashed bursts of cleansing fire. Healers flung runes etched on parchment. For the first time in weeks, the Fog recoiled.
But victory was not without cost. The Fog, realizing the deception, turned violent. Tendrils struck buildings, collapsing rooftops. One healer screamed as black mist seared his lungs. Lysander rushed to his side, knife in hand. He cut open the man's chest just enough to insert a silverwort compress directly into his lung cavity. The healer gasped, barely alive.
"Stay with me," Lysander muttered, his hands shaking but precise.
By dawn, the Fog had retreated—wounded, but not destroyed. The city whispered of triumph, but in the triage tents, the truth was harsher. Dozens had fallen in the decoy ward. The healers were stretched thinner than ever.
Elira approached Lysander, her expression unreadable. "The plan worked. But how long until it learns again?"
Lysander rubbed his temples. "Days. A week at most."
"And then?"
He hesitated. "Then we improvise again. Until something breaks—us or it."
Elira studied him. "You're becoming a symbol, Lysander. People are saying you fight the Fog itself, not just the sickness. They'll expect more of you."
Lysander looked out at the ruins of the ward. "A symbol doesn't bleed. I do."
That evening, as the city tried to celebrate survival with meager rations of bread and broth, a messenger in imperial colors arrived at the tents. His voice carried the weight of command.
"Doctor Lysander," he said, bowing stiffly. "Her Radiance, the Empress, has heard of your deeds. She summons you to the capital."
The room fell silent. The Fog had struck back—and survived. But now, another storm was gathering. And Lysander was standing at its eye.
