The wind howled across the rooftop.
Ami stood at the center of the circular platform, her blade raised, her chest heaving. The clouds churned below her, a sea of gray and white that stretched to the horizon. The sky above was black, scattered with stars that seemed impossibly close.
Across from her, the ancient demon was changing.
It had been wounded. Ichor still dripped from a dozen gashes, its shadowy form flickering and unstable. But there was something different about it now. Something that made Ami's blood run cold.
It was smiling.
"You've impressed me," the ancient demon said. "More than anyone has in centuries."
Ami didn't lower her blade. "I don't care about impressing you."
"No. You care about killing me." The demon's smile widened. "But you can't. Not with that blade. Not with that power."
It raised its hand.
The shadows around it surged, twisting, writhing. A long black staff materialized from the darkness, its surface covered in ancient runes that pulsed with crimson light. Around its upper half, fragments of obsidian orbited in an endless, broken ring.
The Blackstone.
Ami didn't know what it was. She didn't need to. She could feel the power radiating from it—ancient, terrible, beyond anything she had ever faced.
"What is that?" she asked.
The ancient demon's smile widened.
"A forgotten law given form," it said. "A weapon that predates the first demons, the first human kingdoms. A piece of a civilization that was erased from existence."
It raised the staff. The fragments around it spun faster, their runes blazing.
"You've forced me to use this," the demon continued. "You should be proud. No one has done that in millennia."
Ami raised her blade. "I don't care about your weapon. I care about killing you."
The demon laughed—a cold, hollow sound.
"Then come."
Ami attacked.
She moved with everything she had, her blade aimed at the demon's throat. She was fast—faster than she had ever been. But she knew it wouldn't be enough.
She had to be faster.
The demon didn't move. It simply watched her approach, its smile widening.
Then it willed the Blackstone to change.
The fragments detached from the staff, flowing like liquid obsidian. They shot forward, meeting Ami's blade in mid-air. The impact sent a shockwave across the rooftop, shattering the stone beneath them.
Ami was driven back.
She recovered quickly, her blade still raised. The fragments had reformed into a greatsword in the demon's hand—massive, dark, its edge humming with contained power.
"Fast," the demon observed. "But not fast enough."
It attacked.
The greatsword came down in a devastating arc. Ami blocked—barely. The impact sent her skidding across the stone, her boots carving trenches in the surface. She hit the edge of the platform and stopped, her blade still raised.
She attacked again.
The demon met her head-on.
The battle was brutal.
The ancient demon moved with a speed that belied its age, its greatsword carving arcs of destruction through the air. Ami blocked, dodged, countered—but barely. She was losing ground, step by step.
"You can't keep this up," the demon observed. "You're tiring."
Ami didn't answer. She couldn't.
She attacked again.
Her blade found the demon's shoulder, drawing ichor. It grunted, stumbling back. She pressed her advantage, her blade a blur of motion.
But the demon was already adapting.
The greatsword dissolved into fragments, flowing back to the staff. The fragments reformed into a spear—long, deadly, its tip gleaming with dark light.
The demon thrust.
Ami barely dodged. The spear passed inches from her throat, carving a trench in the air behind her. She rolled, came up with her blade raised.
"Impressive," the demon admitted. "You're adapting. But it's not enough."
It attacked again.
The battle continued.
The ancient demon shifted its weapon constantly, adapting to Ami's movements. The greatsword became a spear, then a glaive, then a whip of linked obsidian fragments that lashed out with terrifying speed.
Ami fought with everything she had.
She dodged the whip, rolling under its arc. She came up with her blade raised, driving it toward the demon's chest. It formed a shield at the last moment, blocking her strike.
She was losing.
She knew she was losing. The demon was faster, stronger, more experienced. And its weapon—the Blackstone—was unlike anything she had ever faced.
But she didn't stop.
She couldn't stop.
Because stopping meant everyone died.
She attacked again.
The demon formed a scythe.
The blade curved around, its edge aimed at Ami's neck. She ducked, rolled, came up with her blade raised. The scythe carved a trench in the stone where she had been standing.
"Persistent," the demon observed. "I'll give you that."
Ami attacked.
Her blade found the demon's side, drawing ichor. It stumbled, its form flickering. She pressed her advantage, her blade finding gap after gap in its guard.
But the demon was adapting.
The scythe dissolved, reforming into dual daggers. The demon moved with a speed that caught her off guard, its blades finding her arms, her shoulders, her sides.
She stumbled back, bleeding.
"Not bad," the demon said. "But not good enough."
It attacked again.
The battle stretched on.
Minutes became hours. Hours became an eternity. Ami lost track of time, of everything. All that mattered was the next strike, the next dodge, the next breath.
The demon was relentless.
Its weapon shifted constantly—spear to glaive to whip to greatsword to scythe to daggers to lance. Each form was more deadly than the last. Each attack was faster, more precise.
Ami was covered in wounds.
Her armor was cracked. Her blade was chipped. Blood poured from a dozen gashes. But she was still standing.
"You should have fallen by now," the demon observed. "Why are you still fighting?"
Ami spat blood. "Because I don't know how to stop."
She attacked.
The demon met her head-on.
The clash sent shockwaves across the rooftop. The stone beneath them cracked, the edges crumbling. Ami was driven back, her boots scraping against the surface.
The demon raised its weapon—a massive greatsword, its edge gleaming with dark light.
"Enough," it said. "This ends now."
It swung.
Ami raised her blade to block—
The impact sent her flying across the rooftop. She hit the ground hard, rolled, came up with her blade still raised. Blood poured from a fresh gash on her forehead.
The demon was already moving toward her.
Ami rose to her feet.
She was broken. Exhausted. Covered in wounds. But she was still standing.
"You're not going to win," she said.
The demon laughed.
"Maybe not," it said. "But neither are you."
It raised its weapon.
Ami raised hers.
They clashed again.
The stalemate held.
Neither could gain the upper hand. Neither was willing to fall.
The demon's weapon shifted constantly, its forms blurring together in a whirlwind of death. Ami blocked, dodged, countered. She was slower now, weaker, but she refused to fall.
The demon laughed.
"You're remarkable," it admitted. "I haven't had a fight like this in centuries."
Ami spat blood. "I'm just getting started."
She attacked.
He met her head-on.
The battle continued.
But neither could gain the advantage.
The sun was rising over the horizon, its light filtering through the clouds. The fortress was still burning below them, the sounds of battle echoing from the streets.
Ami was still standing.
The demon was still standing.
They were evenly matched.
And neither was willing to fall.
