By the time Helios returned to the Slytherin Common Room, the atmosphere had already changed in a way that was impossible to miss.
The night before, the room had been quiet—low murmurs, private conversations, the kind of restrained calm that defined Slytherin at its best. Everything had felt measured, controlled, deliberate. Tonight, however, the air itself seemed to hold tension, like the moment before a blade was drawn. It was not loud, not chaotic, but it was no longer calm.
The stone wall slid open at his command, revealing the dim, green-lit chamber beyond. The familiar flicker of the underwater glow filtered through the windows, casting shifting patterns along the walls and floor. Helios stepped inside, his cloak brushing lightly against the stone as the entrance sealed itself shut behind him with a quiet, final thud.
The effect was immediate.
Conversation stopped.
Not gradually, not in scattered patches—but all at once, as though someone had silenced the room with a single command. Voices cut off mid-sentence. Movements stilled. Heads turned.
Eyes found him.
Dozens of them.
Students were gathered throughout the common room—some seated in the low armchairs, others standing in clusters—but every single one of them had turned toward him. There was no attempt to hide it, no pretense of disinterest. Slytherins did not bother with such things when something—or someone—was worth observing.
Helios did not pause. He closed the distance between himself and the center of the room with the same unhurried stride he always carried, his posture relaxed, his expression neutral, as though the weight of attention meant nothing to him. As though this had been expected.
Because it had.
At the heart of the room stood a group of seventh years.
They were easy to identify—not just by age, but by presence. They stood together, not in a tight cluster, but with the subtle spacing of those who understood their own importance. Older. Sharper. Their gazes were not merely curious—they were calculating.
As Helios approached, one of them stepped forward, separating himself from the group with quiet authority. He was tall, broad-shouldered, his posture straight and controlled, his movements economical.
Melvin Selwyn.
The name surfaced in Helios's mind without effort. Pure-blood. Influential family. The kind who had grown up believing that leadership was not earned, but inherited.
"Black."
It was not a greeting.
Helios stopped a few steps away, leaving just enough distance to remain polite—and just little enough to refuse submission. His gaze met Selwyn's without hesitation, steady and unflinching.
"Yes?"
Selwyn's lips curved faintly, though there was no warmth in the expression.
"You've made quite an impression already."
A ripple of quiet amusement moved through the surrounding students, a few soft chuckles slipping into the silence. Not loud. Not disrespectful.
Helios gave a small shrug, the motion casual, almost indifferent.
"I tend to."
Selwyn's eyes narrowed slightly, not at the words themselves, but at the ease with which they were spoken.
"You challenged a professor."
Helios tilted his head a fraction, as though considering the statement.
"Correction," he said calmly. "I asked questions."
The distinction hung in the air, subtle but deliberate.
"That's not how Slytherin operates."
There it was.
Expectation.
Another seventh-year stepped forward slightly, his voice colder, sharper.
"Slytherins don't pick fights with professors."
"Slytherins don't draw attention."
"We don't act like a Gryffindors."
Each sentence was measured, each word placed with care, as though reciting a set of rules that had been followed long before any of them had arrived.
Helios's expression did not change.
"Is that what you think I did?"
Selwyn moved closer, closing the gap by a single step. It was a small movement, but intentional. A test.
"You made noise," he said.
A brief pause followed, just long enough for the weight of the next words to settle.
"And noise attracts problems."
A subtle shift passed through the room. Some students straightened unconsciously. Others leaned forward, interest sharpening in their eyes. The tension tightened, not breaking, but coiling.
Selwyn's expression hardened, the faint amusement gone entirely.
"This house survives by control," he said, his voice quieter now, more deliberate.
"By precision."
"By knowing when to act—and when to stay silent."
Helios listened without interruption, his attention fixed, his posture unchanged. When Selwyn finished, he gave a slight nod, as though acknowledging a point well made.
"And you think I lack that?"
Selwyn did not answer.
He did not need to.
From the side, a girl's voice cut through the silence, smooth and composed.
"If you're going to stay here," she said, "you follow Slytherin principles."
Helios exhaled softly, the breath slow, controlled. For a moment, he said nothing, letting the silence stretch just enough to become noticeable.
Then—
"I have better things to do."
The words were not sharp. Not aggressive.
Just dismissive.
Selwyn's jaw tightened, the first real sign of irritation.
"That wasn't a suggestion."
Helios looked at him properly then—not just at his face, but at him. At his stance, his control, the way he held the room's attention without effort.
And when he spoke again, there was something different beneath his calm.
"You're trying to establish hierarchy," Helios said evenly.
"New student."
"Older house members."
"Put him in his place early."
A faint smile touched his lips.
"Efficient."
The room fell into complete silence.
Because he had spoken the truth aloud.
Selwyn's voice dropped, lower now, more controlled.
"Then you understand the situation."
Helios nodded once.
"I do."
A pause.
Then—
"I just don't care."
The words settled like a weight over the room.
Selwyn stepped forward again, his presence pressing, the space between them narrowing further.
"And why is that?"
Helios did not move.
"Because if you have a problem with me…"
He let the sentence linger, just long enough to draw every eye in the room tighter around him.
Then he finished it quietly.
"…you can challenge me."
Because every Slytherin present understood exactly what he had just said.
A duel.
An unspoken law of the house.
Strength determined position.
Not age.
Not blood.
Not words.
Helios's voice remained calm, steady.
"I'll duel any one of you."
A breath.
"Or all of you."
The air grew heavier, charged with something sharp and dangerous. Students exchanged glances, not mocking, not dismissive—but careful.
Because arrogance was common.
But this—
This was certainty.
Helios closed the door to his room with a quiet, deliberate click, the sound soft yet final as the latch settled into place. For a brief moment, he did not move. His hand remained resting against the wood, fingers splayed lightly as if feeling the barrier he had just created between himself and the rest of the world.
Beyond the door, the Slytherin Common Room continued to breathe.
Low voices rose and fell in a steady murmur, fragments of conversation blending into one another—alliances forming, opinions shifting, quiet judgments being made and remade in real time. It was the natural rhythm of the house, the constant undercurrent of calculation and ambition that never truly ceased.
Helios listened for a few seconds longer, his expression unreadable, before finally withdrawing his hand and stepping further into the room.
He had expected it.
The testing.
The unspoken challenges wrapped in polite words
And then, with quiet precision, decided whether they were worth acknowledging… or worth breaking.
Helios exhaled slowly, the breath controlled, steady.
"Predictable," he murmured under his breath.
But that did not make it unimportant.
If anything, it made it necessary.
He knew this was only the beginning.
Tonight had not been a resolution.
It had been an introduction.
A declaration—unspoken, but understood.
More would come.
More challenges.
Stronger ones.
Smarter ones.
Subtler ones.
And he would deal with them.
Eventually.
But not tonight.
Tonight—
He had other priorities.
Turning away from the door, Helios approached the desk near the far wall. The surface was already neat, untouched by the usual clutter of student life, and he paused only briefly before opening his trunk.
Helios knelt briefly, retrieving what he needed—parchment, a bottle of ink, a fresh quill—before closing the trunk again with a light touch.
He straightened.
Moved back to the desk.
Set the items down in careful order.
Then—
Paused.
His fingers brushed against something else within his pocket.
He stilled for a fraction of a second before drawing it out.
The blood quill.
It rested in his hand, deceptively elegant, its surface smooth, its design almost refined. There was no outward sign of its cruelty—no jagged edges, no twisted form. It was clean.
Helios turned it slowly between his fingers, studying it in silence.
A faint, almost imperceptible smile touched his lips.
"You really shouldn't have done that," he said softly, his voice barely louder than a whisper.
Carefully, deliberately, he placed the quill on the desk.
Set aside.
For later.
Because first—
There was work to be done.
Helios reached for the normal quill, dipping it lightly into the ink before setting its tip against the parchment. The moment it touched the surface, his hand began to move, the words forming with quiet certainty.
The structure of the letter had already been decided long before the ink ever met the page.
Mr. Hemlock,
I hope this letter finds you in good health. I require your assistance in a matter of urgency. There are two individuals in need of intervention—afflicted by a bloodline curse of advanced progression.
The quill moved steadily, each line clean, deliberate.
I would not ask this if it were within the capabilities of conventional healers. It is not.
Your expertise is required.
Inform me of your willingness, and I will arrange the necessary conditions.
—Helios Black
He paused then, the tip of the quill hovering just above the parchment.
Then, with a small, precise motion, he added one final line.
I trust your judgment in this matter.
Helios leaned back slightly, studying the finished letter for a second before setting the quill aside. The ink settled into the parchment, the words firm, unyielding.
He folded the letter with practiced ease and sealed it.
There was no need to consider the response.
Albert Hemlock was not a man who turned away from complexity.
Not when it challenged the very limits of magic.
"He'll agree," Helios said quietly.
It was not hope.
The letter was placed carefully to one side.
Then, without hesitation, Helios reached for his books.
Homework.
He opened them methodically, arranging parchment before him once more. The quill returned to his hand, and soon the steady rhythm of writing filled the room—notes forming in clean, precise lines, each word placed exactly where it needed to be.
To any observer, it would have seemed effortless.
But his mind was not entirely present.
Part of it remained in Dumbledore's office, replaying words, expressions, intentions.
Part of it lingered on Astoria—on her condition, on the urgency that had driven him to write the letter in the first place.
And part of it—
Turned, slowly and deliberately, toward something darker.
Time passed without notice.
When he finally set the quill down, the last of his assignments complete, the room had fallen into a deeper stillness. The distant murmur beyond the door had quieted, reduced to little more than occasional movement.
Helios's gaze shifted.
To the blood quill.
For a moment, he simply looked at it.
Then he reached for it.
As his fingers closed around it, something in the room seemed to change.
Helios rose from his chair and lifted his wand slightly, his movements slow, deliberate, precise.
Magic flowed.
Wards settled into place one after another, each overlapping the last—barriers woven with care, silencing charms anchoring the space, anti-detection fields spreading outward like an invisible shell.
The very air seemed to tighten as the magic took hold, sealing the room completely.
No one would interrupt.
Only when he was satisfied did Helios lower his wand.
He returned to the desk.
Placed a blank sheet of parchment before him.
And picked up the blood quill.
For a moment, he did nothing.
He simply held it.
Feeling it.
The magic within it.
The altered enchantment that now tied it to something beyond its original purpose.
Then—
He pressed the tip of the quill to the parchment.
And began to write.
"I will respect authority."
The words formed slowly.
Far beyond the walls of this room—
That same sensation would be felt.
Helios watched the letters appear, his expression calm, composed.
Then he wrote again.
"I will respect authority."
Again.
And again.
Each stroke deliberate.
There was no rush.
No flicker of emotion.
But beneath that stillness—
There was intent.
"Let's see how long you last," he murmured softly.
Because this was not revenge.
Not yet.
This was a lesson.
And Helios Black had every intention of ensuring that Dolores Umbridge would never forget it.
