Medivh arrived without announcement, which was apparently the only way the Prophet knew how to navigate the world.
One moment, the makeshift hall of the Kalimdor settlement was occupied by its usual weary architects—Jaina, Alleria, Vereesa, Aminel, Tyr'ganal, and a handful of logistics officers.
The air was thick with the smell of damp parchment and the low hum of candles burning toward their wicks.
The next moment, a figure stood at the room's edge who had not entered through any door. He carried a quality of presence that certain individuals possess when they have finally stopped pretending that the ordinary rules of space and approach apply to them. He simply was.
He looked exactly as the legends and the terrified reports described him: a man who contained more than a man's share of knowledge and had found a way to carry it that did not require looking burdened.
Like an ancient library that feels comfortable rather than heavy because its archives are perfectly ordered, Medivh stood with a relaxed, terrifying poise.
His eyes were the most striking feature—Aminel had once tried to describe them to Tyr'ganal as being "present in multiple registers." He saw the room, yes, but he also saw the metaphysical architecture the room was embedded in, the way a master cartographer looks at a village and simultaneously sees the tectonic plates beneath it.
Jaina didn't flinch. She looked at him with the expression she now reserved for the Prophet—not startled, not particularly deferential, but with the careful, evaluating attention of someone who had decided to take the message seriously without necessarily surrendering her judgment to the messenger.
"Prophet," she said, her voice steady in the quiet room.
Medivh inclined his head, the beak-like hood of his cloak casting a sharp shadow. "Lady Proudmoore."
His gaze moved across the others, lingering on Alleria with the look of someone confirming a calculation, before settling back on Jaina.
"There is not a great deal of time for the kind of conversation you would prefer to have. I will tell you what is needed. You will have questions. I will answer as many as I am able, which will be far fewer than you desire."
"That seems to be the consistent rhythm of our interactions," Jaina said, her tone carrying the precise dryness of a scholar who has made peace with a difficult textbook.
"Indeed," Medivh agreed, unruffled. "The Horde needs your help. More specifically, Thrall needs your help. What has begun with the demons is far from finished, and the remaining movements will determine whether the forces assembled against Archimonde are a shield or merely a shroud."
For once, he spoke with a jarring directness. Alleria, watching from the shadows of the room's perimeter, noted the shift in her mental ledger.
Either the situation had become urgent enough to override his love for the cryptic, or he had assessed this specific audience and concluded that riddles would be a tactical waste of time. The name he brought was Grom Hellscream.
To Jaina, the name was a data point from military reports—a figure of significant violence and charismatic, unstable leadership. To Alleria, it was a ghost from the Second War, carrying the specific, metallic weight of a name attached to a genuine threat she had once faced through the sights of her bow.
But Medivh was not describing the Grom of the past. He described a man transformed, a creature who had reached into the abyss and allowed the abyss to fill his veins. The corruption of Mannoroth's blood had been taken into him again, not as a desperate draught, but as a total immersion. He was now a weapon—his own and the Legion's simultaneously.
The Prophet explained that Thrall understood the nature of the rot but lacked the surgical tools to remove it. Force would only kill the host; it would not address the passenger. They needed a vessel capable of acting as a metaphysical lightning rod—something that could pull the demonic taint from the marrow and hold it without shattering.
"A Soul Gem," Jaina said, her mind already three steps ahead. "The containment principle is ancient Kirin Tor orthodoxy. The challenge isn't the theory; it's the calibration. Demonic blood of that concentration acts as a solvent to most arcane matrices. It would eat a standard gem from the inside out in seconds."
"Can it be done?" Alleria asked, her voice low.
Jaina looked at her, her eyes bright with the sudden, sharp focus of a mage who has been presented with an impossible equation. "Yes. It can be done. But the resonance tuning alone—"
"You have two days," Medivh interrupted.
Jaina didn't even blink. "Of course. Two days."
She began immediately. Jaina Proudmoore did not know how to do anything at half-speed. She pulled three of her most capable sorcerers from their work on the settlement's wards and redirected them with the crisp efficiency of a commander.
Aminel was incorporated into the working group without a second thought; her technical grasp of containment theory, honed under Leylin's demanding tutelage, was exactly the stabilizer Jaina needed.
Tyr'ganal became the unit's logistical ghost. He managed the material components—the unglamorous, essential work of gathering, purifying, and arranging the physical reagents.
He moved through the camp with focused economy, ensuring that the mages never had to look up from their calculations to wonder where the next vial of moonstone dust was coming from.
The two days were a blur of intensive labor that didn't feel difficult at the time because the focus required simply absorbed the awareness of exhaustion. Jaina worked at the absolute edge of her capability, her brow permanently furrowed, her hands steady as she wove the containment architecture.
Aminel didn't take shifts; she simply stayed at the table until her eyes bled red, a choice Jaina acknowledged with a silent nod of respect.
By the end of the forty-eighth hour, the Soul Gem existed. It was not a grand, sprawling artifact. It was roughly the size of a closed fist, a deep, pulsating violet that seemed to swallow the light around it.
It felt heavy—not with mass, but with intent. Jaina held it, ran the final verification sequence, and felt the matrix hold. It was a masterpiece of desperate engineering.
"Tell Thrall we are ready," Jaina said.
What followed was a descent into a nightmare. The approach to Grom Hellscream's position required the combined forces of Jaina's expedition and Thrall's loyalists to cut through the Warsong clan.
But these were not the orcs Thrall remembered. They were soldiers operating under a compulsion that had surgically removed their sense of self-preservation.
They fought with a suicidal, mechanical resistance, defending a landscape that the Legion had already begun to warp. And then there were the demons.
Reinforcements from the sky and the shadows converted a difficult battle into a slaughter. Ambushes were laid with a cold, demonic intelligence that understood exactly where the advancing line would be most vulnerable.
Thrall moved through the carnage like a man walking through a fire he had started. Every Warsong orc that fell was a weight added to his soul. He had known their names; he had shared meat and stories with them.
To see them reduced to mindless thralls of the very blood he had fought to escape was a specialized kind of agony. Yet, he did not stop. He couldn't. Stopping was the only option worse than the slaughter.
"Infernals!" Vereesa shouted, pointing her bow toward the sky.
They came as they always did—with the terrible, spectacular momentum of mountains falling from the stars. They hit the ground with enough force to liquefy stone, rising from the craters as hulking, green-flamed monstrosities.
Jaina's sorcerers met them. It was a clash of raw elemental power and refined arcane shielding. They were not equal to every infernal—the sheer mass of the Legion's assault was overwhelming—but they were sufficient.
They held the sky long enough for the ground forces to push through.
When Thrall finally reached Grom, the air was thick with the scent of ozone and burnt blood. The figure in the center of the clearing was Grom, but the person had been subsumed. He was a vessel of pure, screaming malice.
The capture was not the heroic scene the songs would later claim. It was a messy, desperate struggle. Thrall used every ounce of his shamanic power to pin the creature down, while Jaina triggered the Soul Gem.
The artifact flared with a violent, hungry light, dragging the demonic essence screaming from the air and locking it into the violet depths of the stone. Grom went limp, the unnatural red fire in his eyes flickering out into a terrifying emptiness.
The ritual circle was prepared in a secluded glade, chosen for its arcane neutrality. Jaina had her priests positioned at the cardinal points, their voices rising in a low, rhythmic chant.
Thrall's shamans took their places within the inner ring, their drums a steady heartbeat against the silence of the woods.
The two traditions—the structured, cerebral magic of the humans and the raw, spiritual communion of the orcs—found a strange, functional harmony. They shared a purpose, and that was enough to bridge the cultural chasm.
The working that followed was not elegant. It was grinding, resistant labor. The demonic taint had been allowed to settle into Grom's marrow for too long, and pulling it out was less like an extraction and more like trying to separate two metals that had been melted together.
Jaina poured everything she had into the circle. Her mages held their positions even as the feedback from the gem threatened to shatter their concentration.
The shamans called upon the earth and sky to steady the host, providing a spiritual anchor for a soul that was being torn apart and sewn back together. It took hours. It took exactly as long as a miracle requires.
The moment the taint finally broke free wasn't marked by a thunderclap. Instead, the pressure in the glade simply... thinned.
A suffocating weight lifted from the air. The black, oily essence finally surrendered its hold on Grom's heart and vanished into the Soul Gem with a final, defeated hiss.
Grom Hellscream lay in the center of the dirt circle, breathing.
It was just breathing, but it was the most beautiful thing Thrall had ever seen. The unnatural tension was gone. The soul was back in the house, however battered it might be.
The silence that followed was heavy with the realization of what had been achieved. Thrall knelt in the dust beside his friend.
Jaina stood at the circle's edge, her face pale, her hands trembling slightly from the sheer drain of the magic. She felt the hollow, ringing tiredness of someone who has operated at one hundred percent capacity for three days straight.
Alleria appeared at her elbow. She didn't offer a platitude. She simply stood there, a solid presence in the aftermath.
"It held," Alleria said softly.
"It held," Jaina confirmed. Her voice was flat with exhaustion, but beneath it was a flicker of something warmer—the quiet, functional satisfaction of a craftsman who knows the work was good.
Outside the glade, the night had fully claimed Kalimdor. The stars here were alien, their patterns unfamiliar to the elves and humans alike.
The world was still a dangerous, darkening place, and Archimonde was still coming. But as Grom Hellscream took a shaky, human breath, the board had shifted.
One of the Legion's greatest weapons had been reclaimed. Somewhere in the vast, indifferent darkness, the Burning Legion continued its march, unaware that the mortals had just pulled a vital tooth from its mouth.
The weight of a soul had been measured, and for one night, it had been found heavy enough to stay.
