I strolled through the dimly lit corridors of Hogwarts, the stones under my feet whispering history while the walls, if listened to correctly, whispered secrets. Thanatos, draped lazily around my shoulders, flicked his tongue, his voice slithering into my mind with the sharp edge of a teenage cynic.
"Humans. Truly the most baffling creatures. They build castles full of hidden chambers, and yet when a snake uses one for a nap, suddenly it's 'dark magic.' Hypocrites."
I hummed in agreement, running my hand along the cold wall, searching for inconsistencies. The castle had too many layers to be fully mapped out, but I had time. More than they thought. Because while they saw an eleven-year-old, my mind still carried the weight of battles fought and lessons learned far outside the walls of any school.
"And then," Thanatos continued, tail twitching, "you let one of them put you in a uniform. A uniform. You, of all people. It's like dressing a basilisk in house-elf robes."
"Yeah, well, if I start wearing my actual style, Dumbledore might start taking me seriously instead of assuming I'm just a precocious kid."
Thanatos made a sound that could only be interpreted as a scoff. "Doubtful. These people wouldn't recognize competence if it performed a dramatic duel in the Great Hall. Which, by the way, would be a fantastic way to make a first impression."
I smirked, filing that away for later. First, though, the castle. It had secrets, and I was in the perfect position to dig them up. Most people explored Hogwarts with the mind of a child, wide-eyed and enchanted. I explored it like a strategist, looking for leverage. The Marauder's Map? Cute. The Room of Requirement? Predictable. What I wanted were the things hidden before Dumbledore started his chess game with the Dark Lord.
My fingers pressed against a loose stone, and Thanatos lifted his head, interest sharpening his tone. "Oh? Did we just find something fun?"
The stone shifted, revealing a dark passageway descending into unknown depths. I grinned. "We did."
"Finally. Something in this school worth my time."
I stepped inside, the shadows swallowing us whole.
The passage smelled of damp stone and forgotten time. My boots—because yes, I had swapped out the ridiculous school shoes for something practical—scuffed against the uneven steps as I descended. Thanatos coiled tighter around my shoulders, his head resting just near my ear.
"If this leads to another storage room filled with broken cauldrons and sad old textbooks, I'm shedding in your bed out of spite," he announced.
"Noted," I muttered, fingers trailing along the walls. The passage was narrow, old, and untouched by students who relied on the Marauder's Map for mischief. This was different. This was pre-Marauder territory.
The deeper we went, the colder it became. Magic hummed in the air, old and unfamiliar, like something Hogwarts itself had forgotten. I could taste it—something ancient, something hidden not by careless neglect, but by intention.
"Tell me you feel that," Thanatos hissed.
"Oh, I feel it."
A door loomed ahead, wrought iron and heavy, no visible handle. My instincts prickled. This wasn't some prankster's hideaway or a forgotten classroom. This was something someone had locked away.
I placed my hand against the door. The metal burned cold, but more than that—it pulsed. Like a heartbeat. Thanatos flicked his tongue, uneasy now.
"There are many, many things I mock humans for," he said slowly, "but their tendency to seal away horrifying things rather than properly dealing with them is particularly irksome. Do you really want to open this?"
I smirked. "Of course."
The castle wanted to keep this secret. That only made me more curious.
I exhaled, let my magic push against the door, and whispered something I probably shouldn't have. The air around us shivered.
And then, with a sound like a thousand whispers exhaling at once, the door opened.
The door groaned open, dust swirling in the disturbed air, and I braced myself for something horrifying—dark artifacts, cursed skeletons, maybe even a demon bound in ancient chains. Something that would make me pause, something that screamed forbidden.
Instead…
I stepped into what could only be described as a forgotten sanctuary. The walls were carved with symbols I didn't immediately recognize, glowing faintly with a soft, ethereal light. The air was thick with old magic, but not the kind that threatened—it welcomed. At the center of the room, floating just above a pedestal of stone, was a book. Its cover was deep obsidian, shifting like liquid shadow, but when I stepped closer, I saw—no, felt—something else. The book wasn't dark. It was powerful.
And for once, I was speechless.
Thanatos, of course, was not.
"Oh yes, brilliant. You've found the Ancient Mysterious Book Room. How utterly unpredictable. What a shocking revelation. I'm on the edge of my scales with excitement."
I ignored him, stepping closer. The symbols on the walls weren't warning signs—they were wards. Protective, ancient, and written in a language that even Hogwarts itself had forgotten.
"Do you even know what you're looking at?" Thanatos continued, flicking his tail against my ear in irritation. "Or are we just touching ominous floating books now? Because if that's the case, I'll start coiling around cursed objects too, just for fun."
"I don't need to know," I murmured, eyes fixed on the book. "I feel it."
The air practically hummed with magic, and I reached out. Not recklessly—never recklessly—but deliberately, fingers brushing the cover. The moment I made contact, the symbols on the walls flared brighter, and Thanatos let out an exaggerated sigh.
"Oh fantastic, now it's reacting. Yes, let's wake up the ancient magic. That always ends well."
But I wasn't listening anymore. Because the book had responded to me.
And it had opened.
I've always loved Ancient Runes. There's something about them—something more real than wands waving about like conductor batons, more precise than the mutterings of Latin spells people barely understand. Wands are crude tools. Symbols, carved into the very fabric of existence, now that is magic. That's the kind of power that doesn't just react—it remembers.
Which is why, as the book opened, revealing pages filled with shifting runes—old, older than anything even Hogwarts dared to teach—I felt something close to reverence.
Thanatos, however, had absolutely no sense of the moment.
"Ah yes, of course. Why wouldn't it open for you? You, an eleven-year-old child, except, oh wait, you're not actually eleven, so now it makes even less sense. Because obviously, ancient forgotten magic rooms just love handing out their secrets to random intruders with a snake fixation."
I ignored him, eyes scanning the runes as they flickered between languages. Some, I recognized—Norse, Sumerian, something close to Egyptian but twisted in ways that defied proper translation. Others, though… others had no right existing in any human lexicon.
And yet, I understood them. Not perfectly, but enough to know one thing:
This wasn't just a book.
It was a key.
"Oh no. I know that look." Thanatos tightened around my shoulders, his scales cool against my skin. "That's your 'I'm going to do something ridiculous' look. That's the look people have right before they become historical cautionary tales."
"Thanatos."
"No."
"Thanatos, shut up."
"I refuse. I'm the only voice of reason here, and I will not be silenced just because you want to flirt with eldritch magic."
I pressed my hand flat against the open page, and the room breathed. Light pulsed through the walls, and a low, resonant hum filled the space, vibrating through my bones.
And then, the book spoke.
Not in words, not exactly. But in meaning, in understanding. It didn't tell me what it was. It showed me.
Visions flooded my mind—Hogwarts, but before Hogwarts. Before the castle, before the Founders, before wands were ever a thought. A time when magic was written into stone, sung into existence with symbols that shaped reality itself.
I gasped, snapping back into the present, heart pounding. The book was still open, still waiting.
Thanatos, utterly unimpressed, let out a long, suffering sigh.
"Congratulations. You've officially angered something cosmic. Can we leave now, or would you like to start glowing ominously first?"
I knew better. I knew better. Navy SEAL instincts screamed caution, patience, stealth. But those instincts belonged to a man, and right now, I was trapped in the body of a child with raw, unrestrained magic that wanted this. The runes didn't just call to me—they sang. Every part of me flared in response, magic pulsing like a second heartbeat.
I reached out again, unable to stop myself.
"Oh, this is just painful to watch," Thanatos groaned, his tail flicking against my cheek in exasperation. "So much experience, so much training, and yet here you are, touching the ancient glowing book like a toddler with a live grenade. And I'm just supposed to sit here, helpless, while you doom us both."
I ignored him. The runes shifted beneath my fingers, rearranging themselves, testing me, accepting me. A warmth spread through my limbs, not the overwhelming surge of forced power, but a quiet, steady pull—like something waking up with me.
Thanatos let out a long, suffering hiss.
"Fine. Yes. Give in to the magic. Bond with the spooky book. When you start floating and speaking in long-forgotten tongues, don't say I didn't warn you."
I exhaled, my breath coming out sharp. The symbols settled into something readable, something I knew without ever having learned. I ran my fingers over them, tracing their shape, feeling the way they pulsed with recognition.
"Oh fantastic," Thanatos continued. "He's not just touching it. He's caressing it. This is worse than I thought."
I smirked. "You're just mad because you don't have thumbs."
"No, I'm mad because I have sense. A rare trait in this particular room, apparently."
But I wasn't listening. The book wasn't just words. It was a map. A guide to something deeper. Something Hogwarts itself had buried beneath layers of history and misdirection.
And I was going to find it.
Just as I started deciphering the next sequence of runes, the book pulsed—once, twice—then slammed shut with enough force to send dust flying. The glow in the room dimmed instantly, the magic in the air cooling like a parent flipping off the lights and declaring, "That's enough excitement for one night."
I stared at it. Blinked. Then reached for it again.
Nothing. The book was locked tighter than a classified Navy file, its once-responsive runes now nothing more than silent, unreadable symbols.
Thanatos, ever the opportunist, seized his moment.
"Oh ho ho," he drawled, his voice oozing smug satisfaction. "Looks like Daddy Book decided you've had enough fun. 'Go to bed, young man,' it says. 'You're getting cranky.'"
I scowled, drumming my fingers against the closed cover. "It was just getting interesting."
"Yes, and that's exactly why it stopped you. Even the ancient magical artifact has more self-preservation than you do."
I pushed against it, trying to will it back open, but the magic refused to budge. The room, which had moments ago been alive with pulsing energy, now felt... still. Not hostile, not rejecting me—just done with me.
Like an exhausted parent shooing their kid off to bed after too much sugar.
"Unbelievable." I exhaled sharply, rubbing my temples. "You know what? Fine. I'll play your game. But I'm coming back."
"Oh yes, because threatening the sentient book always ends well," Thanatos muttered. "Shall we stomp our little feet on the way out too? Maybe throw a tantrum?"
I shot him a look, but he was utterly pleased with himself, curling smugly around my shoulders.
The book remained silent. The room's magic settled into a neutral hum, like it had already turned its attention elsewhere.
Fine. I'd let it have its moment. But this wasn't over. Not by a long shot.
I had barely flirted with the book—just a little magic-charged curiosity, a casual brush of power, nothing serious—yet in that short interaction, it had managed to tell me one very important thing: magic was dying.
And it was pissed.
Not in the way of raging tempests or fiery destruction. No, this was a colder, sharper kind of anger. The kind that simmered beneath the surface, patient and unrelenting.
The runes had whispered it, over and over, like a bitter truth forced into repetition. The old ways were fading. Magic was thinning. And it wasn't natural. It wasn't some inevitable decline of power across the ages.
It was deliberate.
Thanatos, of course, was less interested in the grand revelations of a sentient book and more interested in making sure I never enjoyed anything ever.
"Oh, fantastic. Magic is dying. What a fun bedtime story. Does this mean you'll finally stop poking at eldritch texts like a lovesick academic, or are we going to double down on the bad decisions?"
I ignored him, my mind racing.
The book wasn't subtle about the cause either. Every time the runes shifted, every time the magic pulsed in warning, it hammered the same phrase into my skull:
"Blood magic is suffocating magic."
The pureblood nonsense.
It wasn't just about bigotry or power-hoarding. Their obsession with "purity" wasn't just political—it was poison. By isolating magic to select bloodlines, forcing it through the same stagnant channels, they weren't protecting it. They were killing it.
And Hogwarts—this ancient, powerful, alive castle—was watching it happen. Trapped in its own layers of tradition and politics, unable to fight back.
No wonder the book shut itself on me. It was done talking.
But I wasn't.
"I know that look," Thanatos muttered, his tail flicking irritably. "That's the 'I'm about to make this my problem' look. Please reconsider."
"Oh, I absolutely won't," I murmured, already thinking of my next move.
Because if magic itself was being strangled, if the very lifeblood of this world was fading—
Then I was going to do something about it.
As much as I hated to admit it, Daddy Book was right. I was tired. The kind of tired that settled into my bones, not just from lack of sleep, but from too much magic, too much discovery, too much thinking all at once.
The book had slammed shut like an exasperated parent saying, "Enough. Go to bed, you little menace." And, begrudgingly, I had to agree.
Thanatos, naturally, wasted no time rubbing it in.
"Ah, so you do possess the ability to recognize exhaustion. Fascinating. I was beginning to think you ran on pure spite."
"I do run on spite," I muttered, making my way back toward the passage. "It's just… currently low on fuel."
"Tragic. Perhaps a nap, or, dare I suggest, an actual full night of sleep? You know, instead of your usual method of 'crash when the body gives out'?"
I rolled my eyes but didn't argue. The door out of the chamber remained open, as if Hogwarts itself was giving me an unimpressed look and holding it open like an annoyed host saying, "Leave."
Fine.
As I stepped through, the door slid shut behind me with a finality that sent a shiver down my spine. The book wasn't done with me. Not really.
But for now, it had spoken.
And I was going to bed.
