The immediate aftermath of a battle is not glory. It is paperwork. It is reports filed in triplicate, inventories of recovered materials, and long, tedious debriefings. The stark, terrifying truth of the Abyss Lector and the corrupted ley line was now a classified secret, locked away in the minds of four individuals and the most secure vaults of the Knights of Favonius. Our victory at Warehouse No. 7 had not won us a war; it had simply revealed the true, horrifying scale of the battlefield.
For me, the weeks that followed settled into a demanding and strangely bifurcated existence. By day, I was Knight Arthur, the promising agent of the 8th Company. I sat with Captain Kaeya, poring over the fragmented data we had. We analyzed the alchemical reports on the scraps of the destabilizer, which spoke of impossible alloys and traces of abyssal energy that defied all known principles of elemental science. We built profiles on the captured Fatui, tracing their histories back to Snezhnaya, trying to find a link to the enigmatic Harbinger, Il Dottore. It was a slow, frustrating grind, a search for a single needle in a nation-sized haystack.
But by night, I was someone else entirely. When the moon was high and the city was wrapped in a blanket of silence, I would slip away to a place I had found, a place that became my secret forge. It was a forgotten storage cellar deep beneath the training grounds, thick with the smell of dust and damp earth, its existence seemingly wiped from all official records. Here, there were no prying eyes, no allies to worry, no captains to deceive. Here, I could confront the other half of my soul.
My new training regimen was an exercise in pure agony.
I would sit on the cold stone floor, close my eyes, and turn my focus inward, past the gentle whispers of Anemo, to the roaring, golden sun of my core template. My goal was simple: control. I started by trying to manifest the smallest possible flicker of Mana Burst in my palm, just as I had in the garden.
The first time I tried it in earnest, the result was a sharp, searing pain that felt like plunging my hand into a blacksmith's forge. My entire arm seized up, and the golden light sputtered and died in an instant. The System's warnings flashed in my vision, cold and clinical.
[WARNING: Unstable channeling of internal energy detected.]
[Vessel's magical pathways are not conditioned for this output. Minor tearing sustained.]
[Pain feedback at 87%. Recommend cessation of activity.]
But I remembered the cold, absolute power of the Abyss Lector. I remembered the weight of my friends' and my city's safety resting on my shoulders. Pain was a variable I could account for. I gritted my teeth and tried again. And again. And again.
Night after night, I endured this self-inflicted torture. It was a brutal, painstaking process. I learned to brace for the pain, to accept it as a part of the process. My Eternal Arms Mastery, I realized, wasn't just for external weapons. The control of one's own energy was also a skill, a martial art of the soul. I began to approach it as such. I didn't just force the power out; I tried to guide it, to feel its 'stance', its 'flow'.
Slowly, agonizingly, I made progress. A flicker that lasted one second became three. A point of light no bigger than a pinhead grew to the size of a marble. The pain lessened from a searing agony to a deep, throbbing ache. The System's reports changed.
[Pain tolerance has increased by 1.14%.]
[Internal energy channels are developing hardened resilience through repeated stress and recovery.]
[Control over low-level Mana Burst has increased to 3.45%.]
My greatest breakthrough came after a solid week of this grueling work. I picked up a splintered piece of a broken training dummy, a simple shaft of wood. Focusing my entire will, I tried to channel the golden energy not just into my hand, but through it, into the wood itself. The pain was immense, different, a deep strain that resonated through my entire body. For a single, glorious moment, the piece of wood glowed with a faint but undeniable golden light, humming with a power it was never meant to hold. Then, with a sharp crack, it disintegrated into dust, the power too much for it to contain.
I collapsed back against the wall, panting and drenched in sweat, my arm screaming in protest. But a triumphant grin spread across my face. It was a tiny, fleeting success. But it was the first step on the path to mastering Knight of Owner. It was proof that this power could be controlled, could be shaped. It was hope.
While I forged myself in secret fire, Jean fought her own battles in the hallowed halls of the library. Her mission was to enlist the aid of Lisa Minci. This was a challenge not of swords, but of wits and patience.
Jean, ever the dutiful knight, arrived at the library with a sealed, high-priority missive from the Grand Master. She found Lisa, as usual, looking less like a powerful mage and more like a pampered cat. She was lounging on a chaise lounge she'd had installed near the restricted section, a half-empty cup of tea on a table beside her, fanning herself with a copy of "The Teyvat Travel Guide."
"Why, Jean-dear," Lisa purred, her eyes still closed. "To what do I owe the pleasure? Don't tell me the Grand Master has you running his errands now. Such a waste of your talents. You look so tense, sweetie. You should really take a nap."
Jean, immune to Lisa's usual provocations when on official business, simply held out the sealed document. "Master Lisa. I have a formal request for consultation from the Grand Master. It is a matter of the highest possible security."
Lisa's hand stopped fanning. She opened one eye, a flash of violet lightning, and her gaze sharpened, the lazy facade melting away to reveal the keen intellect of the Sumeru Akademiya's most distinguished graduate in two centuries. She took the document, broke the seal with a perfectly manicured nail, and read.
Jean watched as Lisa's expression shifted from mild curiosity to focused intensity, and then to a cold, chilling gravity she had never seen on the librarian's face before. The playful flirt was gone, replaced entirely by the formidable scholar.
"An Abyss Lector," Lisa said, her voice a low, serious hum. She placed the document down. "Corrupting a primary ley line nexus within the borders of Mondstadt." She looked at Jean, her violet eyes seeming to pierce right through her. "The Grand Master was wise to bring this to me. And wise to send you. Anyone else would have treated it as a simple monster problem."
She stood up, her movements now filled with a sudden, purposeful energy. "Come with me, Jean."
She led Jean into the restricted section, a part of the library few were ever allowed to enter. The air here was thick and heavy, charged with the latent power of the ancient and forbidden books that lined the shelves.
"A ley line isn't just a river of magical energy," Lisa explained, pulling a heavy, rune-covered tome from a high shelf. It landed on the table with a heavy thud that sent dust motes dancing in the air. "Think of it as the world's circulatory system, its nervous system, and its memory, all rolled into one. They carry life force, elemental power, and the very history of Teyvat. To corrupt one… it's not like poisoning a river. It's like injecting a magical, soul-eating cancer directly into the planet's veins."
She opened the book to a page depicting a spiraling, serpentine symbol, intertwined with a weeping eye. It was an older, more complex version of the one I had seen. "This symbol," she said, her voice grim, "is not of the Abyss Order we know. It is not of Khaenri'ah. This is older. It belongs to a heretical sect that believed the Abyss was not just a force of destruction, but the true, primordial state of the world, and that all of creation was a 'scab' that needed to be peeled away."
The revelation was horrifying. We weren't just fighting monsters; we were fighting a destructive cult with a fanatical, world-ending ideology.
"Can it be stopped?" Jean asked, her voice tight.
"Perhaps," Lisa said, her gaze distant. "Abyssal corruption is like a magical disease. To create an antidote, a 'purification ritual', I need to understand the precise nature of this specific strain of the infection. I need data. A direct reading of the corrupted ley line's elemental frequency and abyssal resonance. A simple alchemical sensor would be detected and destroyed instantly. It would need to be… a living conduit. Someone with a high degree of elemental sensitivity, who could get close enough to essentially 'listen' to the corruption and remember its song."
The implication was terrifyingly clear.
The next day, Jean reported her findings to Kaeya and me in the strategy room. The atmosphere grew heavier with every word she spoke. The ancient cult, the need for a 'direct reading'—it all pointed to one, unavoidable conclusion.
Kaeya paced in front of the wall map, his expression grim. "She's asking us to send a lamb into a wolf's den to ask the wolf what it plans to have for dinner. Sending someone that close to the Lector's ritual… it's a suicide mission."
"Lisa believes it's the only way," Jean said, her gaze fixed on me. She didn't want to say it, but we all knew who Lisa's 'living conduit' had to be. My unique senses, my proven ability to get close to the enemy—I was the only candidate.
The weight of their unspoken expectation settled on me. But it wasn't a burden. It was a clarification. My secret, painful training in the cellar suddenly had a clear and immediate purpose. It wasn't just about my own survival or growth anymore.
"I can do it," I said, my voice cutting through the heavy silence. "I'm the only one who can get close enough. I can get Lisa the reading she needs."
Kaeya and Jean both started to protest, but I held up a hand. "We don't have another choice. We can't fight a war if we don't understand the enemy's weapon."
That evening, I did not meet my friends. I did not walk the city streets. I went directly to my forge, the cold, dark cellar beneath the headquarters. I stood in the center of the room, the knowledge of the coming mission a cold, hard stone in my gut. I thought of Lisa's words, of a magical cancer spreading beneath the homes of people I had sworn to protect. I thought of the pain that awaited me, the searing fire of my own power.
Before, the pain was a deterrent. Now, it was a tool. It was the price of the power I needed.
I held out my palm and summoned the golden light. The pain came, sharp and familiar. But this time, my resolve was absolute. I fed my determination into the flame, pushing past the ache, embracing the burn as a necessary sacrifice. The light in my hand grew, larger and more stable than ever before, the size of a small apple, its warmth pushing back the cellar's chill.
Pain is a price. And for them, for this city, for the chance to fight back, it was a price I was more than willing to pay.
