Avernus, First Layer of the Nine Hells
Zariel sat on her throne of obsidian and blackened steel, wings folded, their once-pristine feathers now red, charred, and corrupted beyond recognition. The throne room of her fortress overlooked the greater Styx, the poisonous waters flowing endlessly below.
She was reading reports when the first messenger arrived.
The imp materialised in a puff of sulfur-scented smoke, bowing so low its forehead almost touched the scorched floor. "My lady, urgent news from Mount Celestia."
"Speak."
"The infiltrator has been compromised, my Lady. Yolinia, the false Kelithar, the brass dragon placed in Lord Urgala's command, was discovered and captured. She attempted to complete her mission despite exposure, but failed. She is currently imprisoned in the fifth heaven, undergoing interrogation. They haven't found the other infiltrator yet, but it's only a matter of time."
Zariel's grip tightened on the armrest of her throne. The metal groaned, beginning to deform under her fingers. "Did you say she was captured, and not killed?"
"The reports indicate she cannot escape or dissolve, my lady. Some form of binding has been placed on her essence. She cannot reform in the Hells. She is trapped there until they choose to release her."
"Unbelievable even Bahamut, that worm could not." Zariel's voice dropped to a dangerous whisper. "How?"
"The method is unknown, my lady. The interrogators are extracting what information they can, but we have no agents left in position to observe the process."
Zariel stood up, moving to the gold polished giant windows overlooking the Styx. Months of careful planning. Months of maintaining Yolinia's cover, feeding carefully curated intelligence to Mount Celestia's forces, waiting for the perfect opportunity to strike at their supply lines.
Ruined.
"Send for me Duke Thalvius. Immediately!."
The imp vanished with obvious relief.
Months of work, compromised. The infiltration network she'd spent years establishing is now vulnerable to counter-intelligence operations. And Yolinia, was trapped and being interrogated, likely revealing every contact, every safe house, every sympathiser Zariel had cultivated in the upper heavens.
The door to her throne room opened. Duke Thalvius entered, a pit fiend whose form radiated barely controlled aggression. He bowed with minimal respect, the gesture perfunctory at best.
"You summoned for me, Archduchess?"
"Your niece," Zariel said, not turning from the window. "The brass dragon you personally vouched for. The one you assured me was prepared for deep infiltration. She failed."
Thalvius's expression flickered. "My lady, I-"
"She was compromised within Months. She lost her composure and attacked someone under the worm Bahamut's protection, revealing herself prematurely. And when she attempted to escape, she was captured." Zariel finally turned, her eyes blazing with hatred and infernal fire. "Your assurances were worthless, and your niece was unprepared. And her failure has cost me months of intelligence gathering, and had she been an ordinary infiltrator, she would not have known so much."
"My lady, if you would allow me to explain-"
"Explain what? How you placed your family loyalty above competence? How you convinced me to trust your blood relative despite my reservations?" Zariel moved toward him with predatory grace. "I gave you the responsibility of selecting our infiltrator. You selected poorly. That failure is yours, and yours alone, to bear."
A second messenger materialised before Thalvius could respond. Another imp, this one practically vibrating with terror.
"My lady," it squeaked, terrified. "Reports from the Styx front. The celestial forces have broken through our defensive positions. They've reclaimed the eastern shore and are pressing toward the secondary fortifications."
Zariel went very still. "What are our casualties?"
"Extensive, my lady. Three cohorts of legion devils were destroyed or scattered. Two pit fiend commanders have fallen. And…an..d..." the imp's voice dropped to barely a whisper, "Duke Ravanos and Duke Belthar are confirmed dead."
"Dead, or reforming?"
"Permanently dead, my lady. A weapon, of some kind of enchanted blade, disintegrated their essences completely. The survivors report that both dukes were reduced to dust within minutes of each other. They cannot reform. They are... gone." The imp trembled.
The throne room temperature dropped twenty degrees in an instant. Frost formed on the obsidian walls despite the hellish heat beyond them. Zariel's wings spread to their full span, each feather edged with cold fire.
"Explain now!" she said, each word glacial. "Everything. Do not leave anything out."
The imp consulted notes scrawled on singed parchment, its hands shaking. "The battle was proceeding as expected, my lady. Our forces held superior positions; the celestials were committing to a frontal assault, and casualties were acceptable on both sides. Then Lord Urgala of Bahamut's court entered the engagement personally."
"Urgala enters the battles regularly. That's not unusual."
"This time, she was wielding a new weapon, my lady. A sword that survivors described as radiating power unlike anything they'd encountered. When it struck Duke Ravanos, his entire form disintegrated. His entire form was unmade completely. His essence didn't return to the Hells. It simply ceased to exist."
Zariel's claws extended, scraping against her throne's armrest. "And Belthar?"
"The same fate, my lady. Lord Urgala pursued him immediately after killing Ravanos. One strike through his skull, and he dissolved into dust. Nothing remains of either duke. Just dust scattered by the winds of Avernus."
"This weapon," Zariel said. "Where did it come from?"
"Unknown, my lady. It appeared in Lord Urgala's possession within the last week. Intelligence suggests it may have been a gift, though we have no information about the source."
Zariel turned to Thalvius, her expression terrible in its cold fury. "Your family's failure has cost me two dukes, strategic territory we've held for a decade, and centuries of careful positioning. The eastern shore was the key to our next major offensive. Without it, we're set back decades at minimum."
"My lady please, I can-"
"You can reform in a year and contemplate your failures." Zariel's hand shot out, wreathed in hellfire, and closed around Thalvius's throat. She lifted him off the ground with casual strength, his massive pit fiend form suddenly looking small and helpless. "Assuming I allow you to return to service at all."
"Please," Thalvius gasped. "Give me another chance. I can fix this. I can find this weapon's source, I can-"
"You had your chance. You wasted it." Zariel's other hand came up, fingers extending into claws that glowed white-hot. "Your kingdom, your forces, your accumulated resources, all of it will be redistributed among the remaining three dukes. Consider it the price of incompetence."
She drove her claws through his chest, piercing the heart that powered his infernal form. Thalvius's scream echoed through the fortress, a sound of agony and betrayal and absolute despair.
Zariel held him there for a long moment, letting him feel the pain, letting him understand the price of failure. Then she ripped her hand free, taking his heart with it.
Thalvius's form collapsed, dissolving into essence that would return to the Hells for reformation. A year, perhaps longer, before he regained physical form. And even then, he'd return diminished, weakened, stripped of everything he'd built.
Zariel crushed the heart in her fist, letting the ichor drip between her fingers. "Let that be a lesson. I reward competence and punish failure. There are no exceptions."
The imps had vanished, wisely choosing to be anywhere else. The throne room was empty except for Zariel and the rapidly dissipating remains of Duke Thalvius.
She stood among the carnage, mind working, two dukes were dead permanently. A decade of progress now undone. She had territory lost that she'd fought for centuries to claim and the eastern shore was the gateway to deeper incursions into celestial-held territory, and now it was back in enemy hands.
All because someone had forged a weapon capable of true-killing her commanders and handed it to her enemies.
She needed to know who. She needed to know how and she needed to ensure it never happened again.
But first, she needed to consolidate. Redistribute Thalvius's resources, and shore up the defensive lines, prevent the celestials from exploiting their sudden advantage. The remaining three dukes would need to work harder, cover more territory, take on additional responsibilities.
They wouldn't be happy about it. She didn't care.
A crystal on her armrest began to glow, pulsing with sickly green light. Zariel stared at it for a long moment, her expression unreadable. Then, with obvious reluctance, she activated it.
A figure materialized in the air above the crystal, translucent and distorted. The features were obscured, hidden, but the voice was clear. Cold. Carrying undertones that made even Zariel's corrupted form feel something close to fear.
"Zariel," the voice said. "I've been reviewing the reports from Avernus. You have lost two dukes lost permanently and positions were abandoned and decades of progress undone in a single afternoon. Would you care to explain how this happened?"
"There was an unexpected complication," Zariel said carefully, keeping her voice neutral. "Mount Celestia deployed a weapon I didn't anticipate. Something capable of permanently destroying infernal essences of even dukes."
The voice carried disappointment. "You're telling me that a single weapon has derailed months of careful planning? This is beneath you."
"The weapon's origin is unknown. My intelligence network was compromised before I could identify the source. I'm already taking corrective measures and additional resources are now being allocated to the investigation and counter-tactics. This setback will be temporary."
"You've lost two of your six dukes. A third has been executed for incompetence. That leaves you with half your command structure and territory you can no longer adequately defend. How, exactly, is this temporary?"
"I will recover," Zariel said, her voice hardening. "I've weathered worse setbacks. The Blood War is eternal. One defeat doesn't determine the outcome."
"One defeat, no. A pattern of failures, however, does." The figure leaned forward, and though Zariel couldn't see the face clearly, she felt the weight of scrutiny and the figures malice. "You've been useful to our larger goals and in combating the forces of the abyss, Zariel. Your position in Avernus provides advantages we value. But usefulness can be replaced. There are other archdevils who would gladly take your position if you prove... inadequate to the task. Do not overreach."
The threat was unsubtle and absolute.
"I understand," Zariel forced out.
The figure dissolved, the crystal's light fading. Zariel sat alone in her throne room, wings folded tight against her back and fists clenched.
