Around us, burning structures began to groan and collapse. And then, the shadows began to behave unnaturally.
The dark magic seeping from the corpses we felled did not dissipate. It was actively being dragged away, slithering over the cobblestones toward the northern plaza as if pulled by a massive, unseen roots. But not all of it escaped.
Directly in our path, the ambient shadows suddenly violently coalesced.
The darkness swelled and melded into a singular, towering nightmare. It stood nearly eight feet tall, completely composed of pitch-black, writhing abyss. Its head was the elongated, grotesque skull of a horned goat.
It moved with deep disturbing steps. From its shadowy hand, a massive, jagged greatsword made entirely of solidified darkness manifested. It locked its void-like gaze onto Ana and swung.
Ana brought her claymore up in a flawless, two-handed parry. But the sheer force of the towering demon was incomprehensible. The impact rang out like a thunderclap. Ana's boots left the ground entirely, the blow sending her flying backward through the air to crash violently into a pile of shattered masonry.
"Ana!" I roared.
Alarmed and running on pure adrenaline, I threw myself between the rubble and the demon.
The goat-headed monstrosity did not even pause to gloat. It stepped forward and brought the shadow-blade crashing down toward my skull. I raised Dark Sister, bracing my legs against the mud.
The blades met. The impact rattled the very marrow of my bones. A sickening pop echoed in my side as my wounds fully tore open, warm blood instantly soaking my tunic. My vision blurred violently, my arms trembling under the impossible, crushing weight of the demon's blade.
I was going to die here, pinned in the mud. The demon raised its blade to deliver the killing stroke.
"Protego Maxima!"
A blinding, shimmering blue dome flared into existence mere inches from my face. The demon's heavy strike slammed into the magical wall, the force rippling across the barrier but failing to break through.
I rolled backward as Ana staggered out from the rubble, her face bruised and her redwood wand raised.
"Confringo!" she screamed.
A volatile streak of explosive orange light slammed squarely into the demon's chest. The concussive blast blew the eight-foot monstrosity backward off its feet. But as it hit the ground, the shadows surrounding it violently swirled, instantly stitching the blasted hole in its chest back together.
"Use the spell from the temple!" I yelled over the roaring fires, adjusting my grip on my sword. "The white light!"
"I can't!" Ana shouted back, her chest heaving in ragged gasps. "I do not have the magical strength left for it to manifest!"
I grunted, spitting a mouthful of blood into the mud. If magic could not kill it, I would have to dismantle it piece by piece.
I went on the offensive. The demon was massive and terrifyingly strong, but its size made it slow. I used every ounce of speed I possessed, ducking under a horizontal sweeping strike and slicing my Valyrian blade across its thick thigh.
As I danced around the beast's lethal arcs, Ana provided a relentless barrage of magical artillery.
"Impedimenta!" she cast. The demon's movements suddenly slowed, as if fighting through deep water, allowing me to score a deep gash across its ribs.
"Bombarda!" An explosion shattered the cobblestones at its feet, throwing it off balance.
"Incarcerous!" Thick, glowing ropes manifested from thin air, violently wrapping around the demon's torso and arms.
The spells were highly effective, but only temporarily. The demon's raw strength allowed it to snap the magical ropes within seconds, and the explosive damage was quickly mitigated by the dark magic. But as I ducked another lethal swing, I noticed a vital shift.
The demon was no longer healing instantly.
The ambient shadows in the alleyway had been entirely siphoned away toward Caraxes' position. Deprived of extra corpses to feed on, the goat-demon was forced to rely on its own dwindling reserves.
"Its healing is failing!" I shouted, parrying a glancing blow that sent a jarring shock up my forearm.
We pressed the advantage. It was a brutal, bloodied dance. The demon managed to clip my shoulder with a shadowy fist, sending me stumbling, and a backhand from its sword hilt grazed Ana's ribs, drawing a sharp hiss of pain from her lips. But we held our own.
Seeing the beast raise its sword for a heavy, two-handed overhead strike aimed at me, I feinted, diving into a roll directly between its massive legs.
The demon tracked my movement, leaving its flank entirely exposed. Ana surged forward. With a fierce cry, she swung her Valyrian claymore in a brutal, sideway arc.
The rippled steel sheared cleanly through the demon's right shoulder. The massive shadow-arm, still gripping its dark sword, severed completely and dissolved into ash before it even hit the ground.
The beast staggered, standing still for countless moments as it stared at its missing arm.
Before Ana or I could deliver the final blow, the air in the alleyway warped. From the direction of the northern plaza, a massive, whip-like tendril of pure shadow slithered through the streets with terrifying speed.
It struck the goat-demon squarely in the back. The tendril did not attack us; it violently siphoned the remaining dark magic from the crippled beast. In the blink of an eye, the eight-foot demon was drained into a withered, empty husk of mortal flesh, which collapsed lifelessly into the mud as the tendril rapidly slithered back toward the plaza.
Ana and I stood frozen, battered and bleeding, trying to process the sheer, impossible scale of the magic that could casually devour a demon of that size.
But we had no time to think.
From the plaza, Caraxes let out a final, deafening roar. Instantly, the sky above the northern district was eradicated by a blinding, piercing emerald light.
The very atmosphere around us shifted. The air grew impossibly thick, heavy with a strong pressure that made the hairs on my arms stand on end. It was the same terrifying, suffocating gravity I had felt in the catacombs when the golden portal had opened.
Ana's emerald eyes widened in sheer panic. She grabbed my arm, her grip bruising.
"My brother," she breathed. "We must hurry!"
I didn't argue. Driven by adrenaline and the terrifying fear of losing my mount, we broke into a desperate, limping sprint toward the blinding green light of the plaza.
As we entered its outskirts I saw a sight that would haunt me to the end of my days as Caraxes lay on the shattered cobblestones his form exhausted and defeated wrapped in chains of emerald light. A man with auburn hair and the very same glowing emerald eyes as Ana carrying a sword walked towards my mount. I was unable to voice words as I gawked upon this ghastly setting. Thankfully my shock did not seem to register to Ana as she flicked her magic stick.
"BROTHER! STOP!"
