PART 1: THE SCRIPTORIUM LESSON (Part 1) : r/HPfanfiction
Professor Riddle turned and walked away. They followed. He led them farther beneath Hogwarts than they had ever ventured. The familiar dungeon corridors soon gave way to narrower passages where the stone grew darker, the air colder, and the torches fewer and farther in between. At last, he stopped before a blank stretch of wall. Harry glanced at Hermione. Hermione shrugged. Riddle placed his palm against the masonry and something began to shift beneath it. A serpent slid out of the brickwork - its carved head rising beneath his fingers as though waking from centuries of sleep. A second serpent emerged, then a third; their stone bodies winding around one another until an archway took shape where no doorway had existed moments prior. A low, grinding rumble echoed through the corridor as the wall withdrew and warm amber light spilled outward. No one spoke. The chamber beyond was much older than any classroom they had ever seen.
Great stone pillars climbed toward a vaulted ceiling half‑lost in shadow, serpent engravings coiling around their bases and disappearing among inscriptions too ancient to decipher at a glance. Bookshelves had been carved directly into the stone walls and filled so completely that parchment and leather seemed to have fused with the architecture itself. Ancient manuscripts rested inside crystal vitrines, and chained tomes occupied entire shelves. Instruments of brass, silver, bone, and lacquered wood gleamed from alcoves between the books, each one humming faintly with purpose.
Yet the room possessed none of the clammy severity associated with the lower dungeons. A broad fireplace burned along one of the lateral walls, filling the chamber with warmth and the comforting scent of crackling firewood. Deep, sumptuous chairs upholstered in black leather tapestry stood nearby. Silver enchanted lamps floated lazily above long worktables, casting soft pools of light onto them. At the room’s centre stood a monolithic circular table of grey stone; its surface marked by centuries of scratches and ink stains. On a smaller table beside the fire rested a silver tea service. Beside it lay a large crystal tray piled to the brim with delicate cakes, crunchy biscuits, fresh fruit, and crystallised pineapple.
Luna could barely contain her excitement. Draco and Pansy, remembering themselves, attempted expressions of cool indifference, as though secret thousand‑year‑old magical libraries were something they encountered every day. Harry and Neville were completely awestruck. Riddle waited until all six students had stepped inside. Then the wall sealed behind them with a soft, final whisper of stone.
“Welcome!” he said, “to my ancestor’s Scriptorium.”
The effect on Draco was almost comical. His spine straightened at once, as though someone had yanked an invisible cord. Riddle’s gaze travelled slowly around the group, resting for a fraction longer on each student than was comfortable. “I trust you appreciate the gravitas of being in this room. Very few students have entered it across these many years… Fewer still have been invited here for private instruction.” Harry looked at Hermione. She knew exactly what he was thinking: Three Gryffindors? In Salazar Slytherin’s secret Scriptorium?
Riddle continued.
“Your presence here indicates that I have observed in each of you an unusual degree of magical potential. Do not mistake that observation for praise, however. Potential is common enough. Fulfilled potential is considerably rarer.” His gaze settled briefly upon Draco. “It is the latter which interests me.” Then, as though he had not just made all six of them feel like they were sitting an examination before the lesson had even begun, Riddle gestured lightly toward the tea table.
“But first, tea. Please, make yourselves comfortable.”
No one dared to move first. Luna did. She picked a raspberry jam cupcake from the tea tray and drifted into one of the leather chairs near the fire with serene delight. The others followed suite, albeit more cautiously, helping themselves to refreshments along the way. Professor Riddle poured himself a generous helping of tea in a brilliant white ceramic cup and placed two pieces of crystallised pineapple neatly on his saucer. He then gathered his robe and sat opposite the students, gazing at them with a look of conniving expectancy. After a short while, it was Harry who finally voiced the question which had been festering in everyone’s heads:
“Professor… is this the Slug Club?”
Draco shot him a contemptuous look, as though the answer were obvious, though his expression suggested he had been wondering the same thing. Riddle lowered his teacup.
“It is.”
He took another sip; his gaze drifting toward the fire. Above it hung a large portrait of Horace Slughorn.
“Professor Horace Slughorn began the tradition long before I was a student at Hogwarts. He had an eye for talent…”
Riddle selected another piece of pineapple from his saucer.
“Although occasionally his vision was clouded by prominent surnames.”
Pansy smothered a laugh. Riddle’s expression did not flicker. He continued.
“I was one of his most favoured pupils, you see. Years later, after he retired, I succeeded him as Head of Slytherin House and elected to continue the tradition of his Club.”
He glanced around at them.
“My principles differ slightly from my former mentor’s, however.”
Riddle took another sip from his teacup before continuing.
“Exceptional students benefit from being exposed to exceptional peers, and magic beyond the ordinary curriculum.”
Hermione found herself leaning forward. Riddle continued.
“I have, however, revised Professor Slughorn’s admissions policy.”
There was something very dry in his tone now.
“Influential relatives are no longer sufficient for qualification.”
Harry looked immediately at Draco. Draco noticed. Hermione kicked Harry under the table before he could smirk. Riddle continued as though nothing at all had occurred.
“House loyalty is similarly insufficient. And pureblood status, although not entirely without merit, is often times a poor substitute for ability.”
His eyes firmly rested on Hermione, narrowing slightly with a mixture of expectation and curiosity. Then he continued.
“If extraordinary magic appears somewhere inconvenient, it is still extraordinary magic.”
Hermione understood perfectly. Coming from Professor Riddle, a Slytherin traditionalist who made no secret of his pride in old wizarding families, it was perhaps the closest thing to a declaration of principle she was ever likely to hear. As the tea break neared its end, Professor Riddle placed his empty cup on the table and tapped it twice in quick succession, producing a pleasant chiming sound.
“Now then,” he said, “allow me to give you a tour of the Scriptorium.”
He rose from his chair, arranging his black cloak and emerald‑green tie with habitual precision.
For the first time, Hermione saw Professor Riddle surrounded entirely by things he valued. And whilst his demeanour was not warmer, he was visibly more alive than before. His stride gained a subtle, eager gait as he moved toward a shelf to the right. His pale hand lingered over glass cases containing ancient manuscripts. When he explained an instrument capable of measuring fluctuations in magical intent before spellcasting, his voice quickened almost imperceptibly. He then showed them a collection of pre‑Ministry defensive devices, fragments of experimental counter‑curses, as well as several artefacts he had recovered and restored himself. Hermione was practically salivating over the artefacts, unsure which one to inspect first. She stopped abruptly before one of the glass cases. Inside lay an old book bound in faded brown leather.
“Professor?” said Hermione.
Riddle turned. Hermione stepped closer, scarcely believing her eyes.
“Is that an original De Structura Mutationis?”
“Yes.” said Riddle.
“But there are only three surviving copies.” said Hermione.
“Four.” said Riddle.
Hermione looked at him. Professor Riddle winked. Of course, he had the fourth!
“A rare find indeed, Miss Granger. Although do keep in mind, that academic knowledge cannot be improved by rehearsing obsolete books.”
“Yes, Professor.” Said Hermione.
Harry rolled his eyes, knowing that Hermione had just mentally added the title to her private catalogue of books she intended to read before she died.
They moved on.
Neville had fallen behind. He stood before a cabinet of preserved magical plants, frowning at a shrivelled specimen suspended beneath a glass bauble.
“P-Professor?” said Neville. The hesitation in his voice made Riddle turn.
“I think this label might be wrong.” Neville pointed.
Draco exhaled sharply through his nose with a quiet scoff of disapproval. Riddle ignored him.
“And why would it be wrong, Mr Longbottom?” he asked.
Neville swallowed, but once he started speaking, the nervousness began to slip away from his mind like water.
“Well, the specimen is labelled Mediterranean, but the wrinkled veining along the leaves, and the unusual thickening at the root suggests it’s a Carpathian variety.”
Professor Riddle hunched over to examine it more closely. The silence stretched long enough for Neville to begin looking nervous again. Then the professor lifted one finger and corrected the label with a small flick of magic. “Well spotted, Mr Longbottom. Ten points to Gryffindor.” Neville’s face lit up. Professor Riddle rarely gave house points, and rarer still to students from other houses. He felt as though he had accomplished an impossible task.
Luna, meanwhile, seemed far more interested in the room itself than its contents. She spent much of the tour trailing her fingertips close to the serpentine carvings without quite touching them. At last she stopped beside one pillar.
“Professor Riddle?” she asked.
“Yes, Miss Lovegood?”
“Does the Scriptorium remember the people who enter it?”
Riddle glanced at the pillar, then back at Luna.
“That it does, Miss Lovegood.”
Luna smiled. “I thought it did.”
Hermione had no idea whether Luna had just asked an extraordinarily perceptive magical question or an extraordinarily Luna‑ish one. She suspected the two were not mutually exclusive. At the far end of the chamber stood an old, ancient-looking desk. Unlike the crowded worktables surrounding it, this one had been left entirely bare. Riddle stopped beside it.
“This belonged to Salazar Slytherin.”
The atmosphere shifted. Even Harry felt it. There was a hint of pride in Riddle’s voice. The table was not merely an antique to him, it was his inheritance – his birthright. Yet when his fingers brushed the ancient, darkened wood, his expression remained sombre and thoughtful rather than reverent. “Some of the earliest works on magical concealment, defensive architecture, and enchantment were developed here. Much of it was brilliant.” He paused. “And much of it was not. Salazar was one of the greatest sorcerers of his age, but he was at times - for lack of a better word - misguided.” Hermione looked at him before she could stop herself. Riddle caught the glance; his bright green eyes rested on hers for the briefest of moments. Then, he said: “An idea does not automatically become correct simply because a great historical figure believed it.” Hermione had not dared to ask about Slytherin’s hostility toward Muggle‑borns. She understood from Riddle’s implication that although he held certain prejudices, he valued magical prowess above all else.
“Now then. Enough reminiscing. Shall we begin?”
Riddle slowly walked away from the ancient desk and approached the round stone table in the middle of the Scriptorium. With a single wave of his hand, the tea leftovers had vanished, though the dish of crystallised pineapple floated loyally towards his side, resting near his elbow at arms-length.
