McGonagall becoming Headmaster might have been a coincidence, but the power of Transfiguration was anything but.
To Roger, Transfiguration was the magic closest to divinity itself.
It could turn metal into cotton, toxins into nourishment, water and fire into a gentle breeze. Even the summoning and vanishing spells within Transfiguration could fundamentally alter the existence of matter. With a single spell, it could render non-magical methods of manipulation utterly obsolete.
Calling it the ultimate control over matter was no exaggeration.
Even the well-known limitations of Gamp's Law—such as the rule that Transfigured food provides no sustenance—weren't flaws of the magic itself. Rather, they stemmed from the way Transfiguration altered material structures, preventing them from breaking down naturally until the spell was undone. If a wizard could transfigure matter at a fundamental level, restructuring it particle by particle into genuine food, it would be nourishing.
The weakness lay not in the magic, but in the wizard.
If someone possessed a mind approaching godhood—an intellect vast enough to comprehend all magical principles—they could theoretically simulate nearly every magical effect through Transfiguration alone. It had the potential to be the ultimate fulcrum, a lever capable of moving everything.
Roger, having received a systematic scientific education in his previous life, was naturally drawn to this rational, structured form of magic. Unlike disciplines that required extreme emotions or spiritual resonance, Transfiguration aligned with logic and deliberate conception rather than instinct and feeling. It was, by its very nature, the most suitable path for him.
Among the many books Professor McGonagall had lent him, one stood out besides Ritual Magic is Far More Than Blood Sacrifice.
It was this book that first made Roger wary of Dark Magic. And it was this book that convinced him that Transfiguration was his best path to immortality.
The book's title?
Is Extreme Emotional Spellcasting a Wrong Path?
It had been written centuries ago, in an era when gruesome, ancient magic was still prevalent. The author, an elderly wizard nearing the end of his life, reflected on the fundamental schools of magic before they evolved into the structured disciplines known today—Transfiguration, Alchemy, Ritual Magic, and more.
In his time, another school of thought had captivated wizards seeking power:
The Emotion School.
Everyone knew that emotions held tremendous influence over the mind. Extreme love, hatred, sorrow, and joy—the desperate will to protect—could unleash unimaginable magic.
Lily Potter's sacrificial spell was the ultimate proof. Even Voldemort's Avada Kedavra had shattered against its power, leaving him defenseless in its wake.
And then there were the Dementors of Azkaban, born from overwhelming despair. The Obscurials, forged by self-loathing and repression.
Emotion, when wielded correctly, could transcend the limits of ordinary wizards.
Ancient sorcerers believed that harnessing emotions was the key to breaking the mind's natural constraints, the path to godhood. But the fate of that philosophy was evident in modern times—wizardkind had moved on, and emotional magic had faded into history.
The book, in essence, was the memoir of an old wizard questioning whether his life's pursuit had been a mistake.
Yet within its pages, Roger found something far more intriguing than personal reflections:
Two radical magical theories.
The Magic Thought Echo Theory and the Magic Choice Theory.
The old wizard introduced these ideas through an analogy that every wizard understood—the wand.
"When I bought my first wand, Mr. Ollivander told me that a wizard chooses the wand, and the wand chooses the wizard."
"Do not covet legendary wands beyond your reach. They will reject you. They will not make you great. In your hands, they will be nothing more than dead wood, unwilling to channel magic."
"This wand—your wand—may seem unremarkable now, but it will grow with you. Every choice you make will shape it, just as it shapes you."
"The greatness of a wizard stems from the choices they make."
Magic and spellcasting, the wizard theorized, operated on the same principle. A wizard did not simply cast spells—the spells chose the wizard in return.
And with that, Roger found himself on the precipice of a realization that could change everything.
"Wizards choose magic, and magic also chooses wizards."
Just as a person without joyful memories cannot cast the Patronus Charm, and one without true murderous intent cannot wield Avada Kedavra, a wizard's nature determines the magic they can harness.
"Wizards influence magic."
A wizard who feels deeply disconnected from the world will naturally excel at Banishing Charms, while someone who craves boundless freedom will have an innate talent for Levitation Charms.
"Magic also influences wizards."
Those who immerse themselves in Dark Magic—spells fueled by hatred, rage, and despair—will inevitably be shaped by it. Over time, they become more brooding, more malevolent, more easily provoked… as if their very essence is being rewritten by the magic they wield.
But it's not just Dark Magic. All spells leave an imprint on their caster.
A wizard who frequently relies on Shield Charms may develop a more defensive, cautious mindset. Someone who masters the Patronus Charm might find themselves leaning toward optimism.
Does that mean magic is dangerous? Not necessarily. The effect follows a simple rule:
The more will and emotion you pour into a spell, the greater the spell's influence on you in return.
If a wizard casts with only mild intent, the effect is negligible. But if they push themselves to their limits every time—pouring their very soul into their magic, veins bulging, heart pounding—then the consequences will be profound.
For most wizards, this isn't an issue. How often does an ordinary wizard cast a spell with life-or-death intensity? Any small influences will naturally fade over time.
But for those who delve into magic that requires extreme emotions—like Dark Magic—there's no escaping its grip.
This understanding made Roger even more wary of magic that demanded absolute emotional investment. More importantly, it solidified a crucial realization:
Choosing the right spell is just as important as casting it.
Take Harry Potter, for example—he used Expelliarmus from start to finish. Was it because he didn't know more aggressive spells? Of course not. But Expelliarmus aligned with his nature, allowing him to wield it with unparalleled efficiency.
Wizards choose spells, and spells choose wizards.
A well-matched spell isn't just effective—it can amplify a wizard's strength tenfold.
Roger's ultimate goal was immortality, and the path he had chosen was the Transformation School, an ancient magical philosophy rooted in Transfiguration.
Most wizards never pursued this path because it required extensive experimentation—something neither ethical nor feasible.
But Roger had an advantage.
His Experimental Holy Body could sense danger, allowing him to push boundaries others wouldn't dare approach. He intended to use it to unlock the mysteries of life itself.
Would it take years? Decades? Or perhaps, like Kuafu chasing the sun or Don Quixote charging at windmills, would his pursuit end in nothing but a wistful legend?
Roger didn't know.
But he did know one thing: since he had chosen the path of immortality, he wouldn't overlook a single opportunity to increase his chances of success.
After rigorous self-testing, he had confirmed two things ,Transfiguration possessed immense, untapped potential and his compatibility with it was extraordinary.
Still, he wasn't so arrogant as to assume he had all the answers. When it came to something as critical as his own future, he would seek wisdom wherever he could find it.
And so, after the final bell rang and the other Gryffindor students filed out of the classroom, Roger remained behind.
He approached the stern yet knowledgeable professor who had guided him so many times before.
"Professor McGonagall, what do you think of my idea?"
