Harry Potter : Eldritch Horrors Chapter 6

Chapter 6: Alchemy

The winter morning air bit through Adam's worn jacket as he made his way through the narrow streets of Camden Market. Several months had passed since leaving the orphanage, and London's December chill reminded him constantly of that first night in the storage room—the cold that had killed his predecessor and nearly claimed him as well.

His fingers, stiff with cold, clutched a small canvas bag containing four carefully selected coins from the 13th century. The market's early hours provided the perfect cover for his transactions; vendors were too busy setting up their stalls to pay close attention to a small boy conducting business with the area's antique dealers.

"Interesting pieces," murmured Mrs. Hartwell, the elderly woman who ran Camden's most discreet antiquities stall. She examined the coins through her jeweler's loupe. "Medieval English silver... the craftsmanship is remarkable. Where did you say you found these?"

"My late grandfather's collection," Adam replied smoothly. The lie had evolved over months of practice, becoming more detailed and believable. "Mum's finally decided to sell some pieces to help with the rent."

Mrs. Hartwell nodded sympathetically. She'd heard similar stories countless times—families forced to part with heirlooms to make ends meet. "I can offer you thirteen pounds for the lot. They're in exceptional condition, but the market for medieval currency isn't what it once was."

Adam accepted the payment without haggling. Mrs. Hartwell was honest by the standards of her profession, and building a relationship with a reliable buyer was worth more than squeezing out a few extra pounds. He tucked the money into his jacket's inner pocket and made his way back toward the Thames.

The past months had established a sustainable routine. Three days a week, he performed street magic in various London locations, carefully rotating his venues to avoid drawing too much attention from any single area. Two days were reserved for coin sales, visiting different dealers and pawnshops across the city. The remaining two days were dedicated entirely to his magical education in Merlin's library.

This systematic approach had yielded steady progress. His street performances had grown more sophisticated as his mastery of the levitation charm improved.

He could now make multiple objects dance through complex patterns while maintaining conversations with his audience, creating an impression of effortless control that drew larger crowds and better donations.

More importantly, his theoretical understanding of magic had deepened significantly. Merlin's research notes were vast and varied, covering everything from basic spell theory to advanced applications of cosmic forces. Adam had developed a personal curriculum, focusing first on protective magic and basic alchemy before gradually venturing into more complex subjects.

Today marked a significant milestone in that education. After three months of careful preparation and study, he was finally ready to attempt brewing his first Horrus Potion.

The extraterrestrial library's herb gardens had proven invaluable for this endeavor. Merlin's agricultural efforts, sustained by the planet's favorable climate and magical properties, had created a thriving ecosystem of rare and powerful plants.

Adam had spent weeks identifying and harvesting the required ingredients: silver moonbell flowers that only bloomed during the new moon, crystallized dewdrops from dream-vine leaves, and powdered bones from creatures that had never existed on Earth.

The few components he couldn't find in the gardens—specifically, processed mercury and distilled alcohol—had been acquired through careful purchases at London's chemical suppliers and apothecaries.

A seven-year-old requesting such materials might have raised eyebrows, but Adam had learned to present himself as running errands for a fictional uncle who worked as a pharmacist.

Back in his current shelter—a disused railway tunnel beneath London Bridge—Adam activated Merlin's ring and transported himself to the library. The familiar sensation of reality dissolving and reforming had become routine, though he still felt a moment of relief each time he arrived safely in the inverted pyramid.

He'd established a dedicated workspace on the library's second level, far from the most dangerous texts but close enough to Merlin's personal laboratory notes for easy reference.

A sturdy wooden table held his collection of brewing equipment: glass vessels, measuring equipments, and a heating apparatus that drew its energy from the same cosmic forces that powered the library's protective enchantments.

The Horrus Potion recipe was deceptively simple in its written form—only seven ingredients combined in specific proportions under carefully controlled conditions.

Adam began by preparing his workspace according to Merlin's safety protocols. He inscribed protective circles around his brewing area using chalk mixed with ground bone from his skeletal finger—a gruesome but effective method for creating magical barriers.

The symbols were complex geometric patterns that hurt to look at directly, designed to contain any dangerous energies that might be released during the brewing process.

The first ingredient, silver moonbell petals, had to be added to precisely heated distilled water at the moment when the liquid reached its boiling point. Adam monitored the temperature using a thermometer that measured not just heat, but the underlying magical resonance of the brewing mixture.

As the water began to bubble, he carefully dropped in the shimmering petals, watching as they dissolved into threads of silver light that swirled through the liquid.

The next three ingredients—crystallized dewdrops, powdered mercury, and essence of nightshade—were added at ten-minute intervals, each addition triggering subtle changes in the potion's color and consistency.

The fifth ingredient proved most challenging: three drops of the brewer's own blood, freely given and mixed with genuine intent to accept the potion's effects.

The Horrus Potion was designed to strengthen mental defenses against cosmic influences, but its method was brutal. Upon consumption, it would force the drinker to relive their most traumatic experience over and over, until their mind either broke entirely or developed immunity to such psychological assault.

For Adam, this meant confronting his death in the laboratory explosion—the full experience his subconscious had recorded: every moment of terror as the ceiling collapsed, every sensation as the massive freezer unit crushed his body, every second of agony as his life ended in darkness and pain.

But the alternative was worse. Without the mental protection the potion provided, continued exposure to cosmic forces would gradually erode his sanity.

Adam steadied his hand and used the bone awl to open a small cut on his palm. Three drops of blood fell into the brewing mixture, which immediately began to glow with a sickly blue-green light.

The final two ingredients—powdered dragon scale and distilled essence of time—completed the process, transforming the potion into a swirling, luminescent liquid.

According to Merlin's notes, the potion had to be consumed within ten minutes of completion, or its potency would begin to degrade rapidly.

Adam sealed the flask and carefully transported it back to his shelter, where he could experience the potion's effects without risking damage to the library or any unwanted magical resonance that might attract cosmic attention.

In the dim light of the railway tunnel, surrounded by the sounds of London's evening traffic, Adam raised the flask to his lips. The liquid tasted like copper and acid, burning his throat as he forced himself to swallow every drop.

For several minutes, nothing happened. Adam began to wonder if the brewing process had failed. Then reality shattered around him like glass.

He was back in the laboratory, hunched over his research station as he carefully measured and added chemicals.

The explosion began slowly—a containment breach in the experimental chamber above, followed by the groaning of metal and concrete as the supports failed.

But this time, Adam felt everything. The moment of realization as the ceiling began to collapse. The desperate attempt to reach safety as tons of debris rained down.

The impact of the freezer unit as it struck his body, crushing bones and organs. The darkness closing in as his nervous system shut down, neuron by neuron, leaving him conscious but helpless as death claimed him slowly.

The experience repeated immediately upon ending, then again, each iteration as vivid and terrible as the first. Time became meaningless as Adam lived through his death dozens of times, hundreds of times.

But gradually, something changed. The terror began to fade.

He found himself observing the process of dying rather than simply experiencing it, noting the sequence of death. The pain remained, but its power to overwhelm him diminished with each turn.

After what felt like hours—or perhaps days—the visions finally ended. Adam found himself lying on the tunnel floor, his body drenched in cold sweat but his mind clearer than it had been since his arrival in this world.

The Horrus Potion had worked. He now had some real protection against the psychological assault of cosmic forces.

This defense wasn't absolute—nothing could completely shield a human mind from the ultimate truths of existence—but it was substantial enough to allow him to study more advanced magical principles without risking madness.

Adam struggled to his feet, his legs shaky from the experience. Outside the tunnel, London continued its nightly routine, millions of people going about their lives in blissful ignorance. He envied them their ignorance even as he acknowledged that his path lay in a different direction.

Tomorrow, he would return to the library and begin studying more advanced Merlin texts—materials that had been too dangerous to approach before gaining the Horrus Potion's protection.
