The library of the Castle of Eternal Night was not what Marcus expected.
He had anticipated a dungeon of forbidden lore—walls lined with grimoires bound in human skin that whispered madness into the ears of the foolish, jars of pickled eyeballs staring from dusty shelves, and scrolls detailing the apocalypse written in fresh blood. He expected the air to smell of sulfur and ancient rot.
Instead, he found himself in a massive, vaulted sanctuary that smelled of vanilla, old parchment, and expensive lemon floor wax.
Sunlight—filtered through stained glass windows depicting distinctively unholy scenes of demons frolicking in pastoral meadows—warmed the mahogany shelves that stretched three stories high. Floating magical candles drifted lazily between the aisles like fireflies, providing soft reading light for the handful of monsters browsing the collection. A minotaur in reading glasses was carefully turning the page of a tiny book with his massive fingers.
"Plan B: Find a Weapon," Marcus muttered to himself, scanning the titles. He pulled a heavy, dust-covered tome from a shelf labeled Human Anatomy & Dissection.
He opened it, hoping for diagrams of demon weak points, nerve clusters, or recipes for lethal poisons.
Instead, he found colorful, pop-up illustrations of a goblin performing the Heimlich maneuver on a choking peasant, complete with helpful arrows.
[Item Identified: "First Aid for Dummies (Goblin Edition)"][Stats: Damage 1 (Papercut) | Utility +5 Medicine Knowledge]
Marcus shoved the book back onto the shelf with a groan of frustration.
"This place is a farce," he whispered, mostly to convince himself. "It's a trap. An elaborate, comfortable honey trap designed to lower my guard before they eat my liver with fava beans and a nice Chianti."
"Sssssilence, please."
A voice hissed from behind a stack of books on the next shelf. It sounded like dry leaves scraping over cold stone.
Marcus jumped, spinning around in his silk robe and dropping into a karate chop stance he hadn't used since he was five years old. "Who goes there? Show yourself, demon!"
A head peeked out from the aisle. It was a woman—or the upper half of one. She had pale, scholarly skin that looked like it hadn't seen the sun in decades, long green hair tied in a messy bun held together by quills, and thick, round spectacles perched on her nose. Below her waist, however, there were no legs. Instead, a twenty-foot-long emerald serpent tail coiled effortlessly around the bookshelves, supporting her weight as she loomed over him.
A Lamia. A high-ranking snake demon.

"This is a library, Mr. Hero," Scylla hissed softly, pushing her glasses up the bridge of her nose with a clawed finger. Her forked tongue flicked out quickly to taste the air, analyzing his scent. "Not a battleground. Please lower your voice, or I will have to revoke your library card. And I have very strict overdue policies."
"I... I don't have a library card," Marcus stammered, gripping his sheer robe tight to cover his chest as he realized how underdressed he was for a battle of wits.
"Then fill out form 3B at the front desk," she pointed lazily with the tip of her tail toward a mahogany counter. "And please, stop radiating so much anxiety. You are disturbing the dust motes. They are very sensitive."
She slithered away, the scales of her tail whispering against the floor, returning to shelving a stack of what looked suspiciously like bodice-ripper romance novels, muttering about "inaccurate hemipene descriptions in modern literature."
Marcus leaned against the bookshelf, sliding down until he hit the floor. He felt ridiculous. He was the Chosen One. The Wielder of Lightbringer. The Hammer of the Dawn. And he was being shushed by a snake-woman librarian for being too loud.
He looked at the digital clock floating in his vision.
[Time until Session Two: 04 Hours 15 Minutes]
The numbers were ticking down like the timer on a bomb.
"Four hours," Marcus breathed, his heart rate spiking. "Four hours until 'Oral Administration'."
He tried to imagine what that meant. His mind, corrupted by years of forced celibacy and the recent... events, conjured images that made his face burn hotter than a fireball spell. Was it literal medicine? Was it... that? Or was it some demonic torture where she would talk him to death about tax evasion and zoning laws?
"Think, Marcus. Focus," he slapped his cheeks, the sting grounding him. "Distract yourself. Knowledge is power. Know thy enemy."
He grabbed another book from a lower shelf, avoiding the spine that looked like it might bite. This one was titled: The History of the Light: An Unauthorized Biography.
Curiosity piqued, he opened it.
The first page didn't praise the Goddess. It didn't speak of her benevolence or her grace in creating the world. It showed a moving illustration of the Great Calamity—not caused by demons rising from the earth to destroy, but by a blinding beam of light descending from the heavens, vaporizing a human city in an instant.
Text:"The Church claims the demons rose from the earth to destroy. The geological records show we rose to a shield. The excess Yang energy of the Goddess scorched the land, creating the deserts. The demons, beings of Pure Yin, were the only natural counterbalance to the overheating of the world."
Marcus frowned. "Propaganda. Lies."
But as he turned the pages, he saw dates. Battles he had fought in. Massacres he had witnessed. The book claimed the 'Demon Raids' were actually rescue missions to save demi-humans from Church inquisitors.
He stopped at a page detailing the destruction of the Elf Village in the North. The Church said demons burned it to the ground. But Marcus remembered arriving there. He found no bodies. Just ash. And footprints. Footprints that led away from the fire, toward the mountains, not into it.
"Elena..." he whispered.
He remembered her face during that mission. She had been crying. He thought it was from the smoke. Now, he wondered if she was crying because she knew who really started the fire.
[Corruption Level: 1.5% (The Seed of Doubt)]
Marcus slammed the book shut. Dust flew into the air, dancing in the light.
"No. I won't listen to this."
He stood up, his heart pounding against his ribs, not from fear, but from confusion. He needed to leave. He needed to go back to his room before his mind betrayed him completely.
The VIP Ward - BedroomOne Hour Before Session Two.
The waiting was worse than the torture.
Marcus had paced the length of his room exactly four hundred times. He had counted the tiles on the ceiling (there were 256, and three were cracked). He had even tried to do push-ups to burn off the energy, but his arms gave out after five reps, prompting a snarky comment from the System about his "noodle arms" and lack of protein.
The sun had set outside the window. The magical torches in the hallway flickered to life, casting long, dancing shadows that looked like grasping claws reaching under his door.
Knock. Knock.
Marcus froze mid-pace.
"Enter," he squeaked. He cleared his throat desperately to sound more masculine. "I mean... Enter."
The heavy oak door creaked open.
General Grognak did not enter. Instead, he stood by the door like a bouncer at an exclusive club, bowing respectfully to let someone else pass.
Elena stepped into the room.
She wasn't wearing the nurse's outfit anymore. Nor was she wearing her royal gown.
She was wearing a pristine, white medical lab coat.
But unlike the doctors Marcus had seen in the capital, who wore sensible tunics underneath, Elena wore absolutely nothing beneath the coat except a black lace corset and a matching garter belt. The lab coat hung loosely off her shoulders, teasing glimpses of pale skin, dangerous curves, and sheer stockings with every step she took.
She held a clipboard in one hand and a small vial of glowing blue liquid in the other.
"Good evening, Patient Zero," Elena purred, her voice smooth as velvet and dark as midnight. She walked over to the desk and set down the vial with a soft clink. "I heard you visited the library. Did you find anything... stimulating?"
Marcus swallowed hard, his throat dry. "Just... lies. Demon propaganda."
"History is written by the victors, Marcus," Elena turned to face him, leaning her hip against the mahogany desk. The slit of the lab coat opened, revealing a long, stocking-clad leg that seemed to go on forever. "But the losers usually keep better diaries."
She tapped the clipboard with a pen.
"But we're not here to discuss history. We're here for Session Two."
She looked at him. Her crimson eyes weren't glowing with wild lust this time. They were glowing with clinical precision, mixed with a hint of sadistic amusement that terrified him more than any monster.
"How are your energy levels?" she asked.
"I... I feel fine," Marcus lied, backing away until the back of his knees hit the bedframe. "Really. The bacon helped. I don't think we need to do this. Maybe we can skip a week? Let my body recover naturally?"
"Wrong," Elena said, stepping closer. She invaded his personal space, the scent of lavender and ozone overwhelming his senses.
She reached out and placed a cool hand on his cheek. Her thumb traced his lower lip, pulling it down slightly to inspect his gums.
"Your Yin levels are dropping. The Parasite is waking up. Can't you feel the heat returning?"
Marcus focused inward. She was right. A faint, simmering warmth was building in his chest again. Not pain yet, but the promise of it. The fever was coming back, a sleeping dragon opening one eye.
"I..." Marcus trembled under her touch. "What is... Oral Administration?"
Elena smiled.
"Well," she whispered, leaning in until her lips brushed his ear, sending shivers down his spine that had nothing to do with magic. "The most direct path to the core of your Holy Energy is through the throat chakra. But since you humans are so... fragile..."
She pulled back and held up the blue vial.
"We need to lubricate the pathways first."
She handed him the vial.
"Drink this. It's a mana-conductive elixir. It tastes like blueberries and shame."
Marcus looked at the vial, watching the liquid swirl, then at Elena's expectant face.
"And after I drink it?"
Elena's smile widened, revealing her sharp, predatory canines. She gently pushed him backward until he fell onto the bed, the mattress catching him softly.
She didn't climb on top of him this time. Instead, she knelt on the floor between his legs.
Marcus's heart stopped.
"After you drink it," Elena looked up at him, her eyes locking onto his with an intensity that promised ruin. "I'm going to extract the poison using a technique I learned from a very talented Succubus Queen."
She patted his knee reassuringly.
"Don't worry, Hero. I promise not to bite... unless you ask me to."
[QUEST STARTED: SESSION TWO][Objective: Do not pass out][Difficulty: EXTREME]
Marcus uncorked the vial with shaking hands. He looked at the ceiling, praying to a Goddess he no longer trusted, before downing the blue liquid in one gulp.
It burned going down. It tasted sickeningly sweet.
And as Elena lowered her head, Marcus realized that saving the world had never been this hard.
