I returned to the Ravenclaw common room that evening and went about my routine as usual. No announcements. No subtle hints. I didn't flaunt the fact that I had been invited to the Charms Club—there was no need. If anything, it was better this way. Let results speak when the time came.
The next couple of days passed quietly.
Too quietly.
The comments didn't stop, but they dulled, turning into sidelong looks and conversations that paused the moment I entered a room. Badeea and Tulip remained constant, as did a few first-years who didn't care enough about house politics to play along. That was enough.
Thursday evening arrived sooner than I expected.
I left the common room alone, making my way through the familiar corridors toward the Charms classroom reserved for club meetings. Halfway there, I spotted Alastair leaning against a pillar, arms crossed, expression relaxed in that infuriatingly composed way of his.
"So," he said, falling into step beside me, "ready to scandalize Ravenclaw?"
"I'm just attending a club I was invited to," I replied lightly. "What they do with that information isn't my problem."
He smiled, clearly amused. "That's usually how trouble starts with you."
As we entered the classroom, the chatter inside dipped—not stopped, just… recalibrated. Several upper-year Ravenclaws were already present, seated in small clusters, wands and parchments laid out neatly. A few faces I recognized stiffened the moment they saw me.
Good.
Professor Flitwick stood at the front, animated as ever, perched atop a stack of cushions. His eyes brightened the moment he noticed us.
"Ah! Miss Black, Mister Salvius–P," he said cheerfully. "Right on time."
That was when the whispers truly began.
Flitwick raised a hand, and the room quieted almost instantly.
"Before we begin," he said, beaming, "I'd like to introduce two new members joining us this term."
A few surprised looks were exchanged. One or two skeptical ones.
"Miss Blake Black and Mister Alastair Salvius–P have been invited," he continued, "for their collaborative work on an advanced variation of the Lumos charm—one that demonstrates not only illumination control, but complex light manipulation inspired by non-magical optical theory."
That got their attention.
I felt it—the shift in the room. Curiosity edging out disdain. Interest overriding prejudice, if only slightly.
"This club," Flitwick went on, voice firm now, "exists to explore magic beyond year boundaries and beyond assumptions. Skill, creativity, and discipline are the only qualifications here."
His gaze lingered just long enough on the back rows to make his meaning clear.
I took my seat beside Alastair without a word, meeting a few lingering stares calmly.
Professor Flitwick clapped his hands together lightly, clearly pleased by the anticipation in the room.
"Excellent," he said. "Today's discussion will center on the spell you two presented in class—Lumos Proiectura."
A ripple of interest moved through the room.
"To begin," he added, turning toward me, "Miss Black, would you care to demonstrate?"
I stood, raised my wand, and cast the spell with a smooth, deliberate motion.
"Lumos Proiectura."
Light unfurled from the wand tip—not as a glare, but as a controlled plane. It resolved into an image suspended in the air: first Professor Flitwick himself, rendered in soft silver-blue light, then an owl that beat its wings silently, followed by a dragon coiling in place before exhaling a plume of flickering fire. The spell ended cleanly, dispersing without residue.
Flitwick's eyes shone.
"Now then," he said, turning to the group, "how do you believe the image is generated? And how are different colors incorporated without destabilizing the charm?"
Before anyone else could respond, one of the older Ravenclaw students—one who had never bothered hiding her disdain for me—spoke up.
"It's rather rudimentary," she said briskly. "We already have Lumos variants with different colors. The red flare, for instance. This spell is clearly just switching between those variants while shaping the light. Any competent wizard can alter the shape of a Lumos construct."
She looked faintly smug, as though she'd already won the argument.
Professor Flitwick didn't respond.
Instead, he looked at us.
Before I could open my mouth, Alastair spoke, his tone polite to the point of irritation.
"As expected of our seniors," he said mildly. "A very textbook answer. If that is the case, perhaps you could demonstrate it for us. You already know the incantation."
What he said was courteous.
What he meant was unmistakable.
The senior seemed to take it as praise.
She stepped forward confidently and raised her wand.
"Lumos Proiectura."
A ball of light appeared—bright, well-formed—but flat. It shifted colors smoothly, cycling through reds, blues, and greens. Gradually, with visible effort, the light stretched and folded, forming the vague outline of a bird.
The room murmured in approval.
I tilted my head slightly. "Senior," I asked evenly, "could you make it a green bird, with a red underbelly and a yellow beak?"
Her confidence faltered.
Still, she tried.
The bird's body shifted to green. After a moment of strain, the underside flushed red. Sweat beaded at her temple as she attempted the beak.
The light flickered.
The structure wavered.
And then the spell fizzled out entirely, dispersing in a shower of harmless sparks.
Silence fell over the room.
Professor Flitwick adjusted his glasses slowly.
"An admirable attempt," he said kindly, "and a useful demonstration."
He turned back to us.
"Miss Black," he prompted gently.
I nodded.
"The issue," I said calmly, "is that Lumos Proiectura doesn't rely on switching Lumos variants at all—and it doesn't use every color you think you're seeing. The only thing you got half right was intent shaping the construct."
She bristled immediately.
"That's not possible," she snapped. "We all saw the colors change. And what do you mean half right?"
Her voice was rising now—emotion bleeding into what should have been analysis.
Before she could continue, Professor Flitwick raised a hand.
"Miss Black, please go on," he said, eyes bright with genuine curiosity. "I find myself very interested in where this explanation is heading."
I inclined my head slightly and glanced at Alastair.
"Al—if you would demonstrate."
He nodded once and raised his wand.
"Lumos Proiectura."
Above his wand, the Ravenclaw coat of arms formed—clean lines, precise proportions, unmistakable. Blue and bronze shimmered exactly as tradition dictated.
"As you can see," I said, "Ravenclaw's colors are blue and bronze. But note this—bronze is not actually being produced."
The image shifted smoothly.
Slytherin's serpent replaced the eagle, silver scales gleaming against green.
"Here," I continued, "no silver."
The lion of Gryffindor followed.
"No gold."
Then Hufflepuff's badger.
"Neither yellow nor black."
A murmur spread through the room.
"In all cases," I said evenly, "we are using only three colors."
I raised three fingers.
"Red. Green. Blue."
I paused deliberately before continuing.
"We'll return to color in a moment. First—shape."
I turned slightly toward the earlier speaker.
"I am not reshaping the spell," I said. "I am not sculpting light the way you attempted to sculpt your bird. That approach treats Lumos as a single, continuous construct."
Alastair's wrist moved—just a fraction.
The image breathed.
Fine gaps appeared across the projection, subtle at first, then unmistakable. The symbol didn't break—but it resolved.
Thousands of pinprick lights became visible.
Miniature Lumos spheres.
Perfectly aligned.
Perfectly stable.
"This," I said quietly, "is not one Lumos."
I looked around the room.
"It is thousands."
Silence followed—thick, thoughtful silence, the kind Ravenclaws respected.
"Each sphere emits only one of the three base colors," I continued. "Their brightness, proximity, and overlap create the illusion of secondary colors—bronze, silver, gold, even black—without ever producing them directly."
Professor Flitwick leaned forward so far on his stack of books that one nearly slipped.
"Additive light theory," he murmured. "Brilliant."
"Exactly," I said. "We're not changing shape. We're revealing and concealing clusters. Intent doesn't force the spell—it selects which spheres are active."
I glanced back at the senior who had spoken earlier.
"When you tried to recolor the beak," I added gently, "you were fighting the spell. You attempted to force a continuous construct to obey multiple contradictory intents at once. Instability was inevitable."
Her face had gone pale—not from humiliation, but from realization.
Alastair dispelled the projection with a flick of his wand, the light dissolving cleanly, without residue.
"That," I finished, "is why Lumos Proiectura is stable. And why it can display motion, depth, and detail without collapsing."
Professor Flitwick straightened, clapping once—sharp and decisive.
"Extraordinary," he said, eyes shining. "Absolutely extraordinary. This isn't just a clever charm—it's a framework. A new way of thinking about light-based magic."
From that day forward, the seniors stopped bothering me.
Whether it was respect for my work, discomfort at being proven wrong, or simple fear of Professor Flitwick's sharp memory, I neither knew nor cared. What mattered was the result. The whispers quieted. The looks changed. Doors that had once been subtly closed were now left ajar.
Life at Hogwarts became smoother—almost deceptively so.
And with that weight lifted, my focus shifted.
The spell.
Lumos Proiectura was no longer just a clever classroom demonstration or a means of survival among judgmental seniors. It was something more—structured, repeatable, scalable. A concept that could be formalized.
I began outlining the paper that same week.
I cross-referenced existing Lumos variants, carefully noting where they failed to address image persistence or spell strain. I cited historical charms texts, Arithmantic light theory, and a handful of obscure spell-crafting essays most students never bothered to read.
Professor Flitwick reviewed my drafts with the enthusiasm of someone watching a field evolve in real time. His suggestions were precise, his corrections gentle, his excitement impossible to miss.
For the first time since arriving at Hogwarts, I wasn't reacting to the world around me.
I was shaping something that would last beyond it.
