Harry Potter : Cael Vale’s journey to Hogwarts

After playing around under the rain in his cat form, Cael decided to head back to the castle. He wanted to test the new spell he had discovered—an ancient spell he hadn't seen in any book before. His tiny paws pressed into the muddy ground as he padded toward the towering castle walls.

"Wow… so this is what Professor McGonagall feels like when she's in her cat form," Cael thought, amused by the strange sensation of having a completely different body. "It's odd… walking on all fours, having paws instead of hands and feet… and this extra limb—the tail—it's weird to control."

As he wandered along the path, the System's voice suddenly spoke in his mind.

"Host, you should be proud. You're talented in Transfiguration. Most Animagi are, because becoming one is deeply connected to Transfiguration. It's not something just anyone can do."

Cael grinned, though as a cat, it looked more like a mischievous baring of teeth than a human smile.

But then a thought struck him. "Wait… If I'm a cat now… would I have the urge to chase mice? Or pounce on things that look like toys? And don't Animagus forms affect your personality over time? I remember reading that the animal traits can influence the wizard's behavior after too many transformations… I really hope I don't end up craving mice or becoming lazy and arrogant…"

The thought made him shudder slightly, his little black tail flicking behind him as he reached the castle. Everything looked massive from this new perspective—the high walls, the grand doors, the towering ceilings.

As he trotted down the corridors, the portraits lining the stone walls stirred to life, their painted faces peering down at him with curiosity and suspicion.

A woman dressed in stiff Tudor-era robes wrinkled her nose.

"Ugh, a black cat wandering the halls? That's never a good sign," she muttered.

Further along, a knight in rusted armor chuckled, tapping the hilt of his sword.

"Careful, little beast—some say black cats bring curses. And Hogwarts has plenty of those already."

Cael's tail twitched with irritation, but he ignored them, his small paws padding silently across the floor as he made his way toward the seventh floor.

An elderly wizard in a faded portrait leaned forward, squinting at him.

"That cat… pure black… Haven't seen one like that roaming these halls in years," he mumbled. His eyes narrowed. "Bad omen, that is."

Nearby, a young witch with wild auburn hair grinned brightly.

"Nonsense, he's adorable!" she exclaimed, winking at Cael as he passed. "Trouble, maybe—but adorable."

Cael slipped by, silent and graceful, his bright blue eyes shining in the torchlight. Still, the murmurs of the portraits followed him like whispers in the wind.

"Bad luck…"

"A sign of mischief…"

"Hogwarts doesn't need more dark omens…"

The words prickled at the edges of his mind, but he pushed them aside. Superstitions. Old fears. That's all they were.

Even though the Black Cats are really not bad 

Even in the Muggle world, black cats have always been seen as a bad omen—symbols of evil, or even creatures connected to the Devil himself. Some believed black cats were the Devil's minions, or that they were his transformed form, roaming the world in disguise. Since ancient times, people hunted them down. There were even jobs created just for that—every black cat killed earned a reward from the Church. Sometimes it was coins, other times, promises of salvation—people were told that killing a black cat would guarantee their place in Heaven after death. The fear ran deep. In old stories and books, black cats were always linked to wicked witches who lived hidden in dark forests, snatching children from villages and casting dark spells under the cover of night.

Finally, Cael reached the stretch of blank wall on the seventh floor. He paced back and forth three times, focusing on what he needed: a hidden room, a safe space where he could shift back into his human form.

The stone wall shimmered, and a door appeared as if it had always been there.

The Room of Requirement had answered.

Tail held high, paws steady, Cael padded inside. The door vanished behind him.

Once safely inside, he shifted back into his human form. The transformation drained him—his knees buckled, and he fell to the floor, exhausted from the magic it demanded.

The room, reacting to his state, conjured a comfortable sofa beside him. Cael sank into it with a sigh, letting his body rest. For nearly an hour, he sat in silence, breathing deeply, the warmth of the room settling around him.

When he finally felt ready, he stood up and stretched. "Alright… let's practice this spell," he said to himself, raising his wand.

With a steady hand, he cast the spell.

"Aegis Vitae."

A soft mist emerged from his wand, swirling gently before wrapping around his body. From the outside, it looked like he stood inside a shimmering bubble of silver mist.

Cael's eyes widened. "Wow… so this is what it feels like to cast an ancient spell…" He tilted his head. "System… will this protect me from the Killing Curse?"

The System replied instantly.

"No. The shield can protect you from almost anything, but not the Unforgivable Curses. They are tied to the God of Death himself—and death cannot be defeated."

Cael frowned, but nodded. "Still… better than nothing. But why does the shield only cover my body? Why doesn't it expand around me… like a barrier to protect the space I'm in too?"

The System answered calmly.

"You can expand it. Just pour more magic into it. The stronger your magic, the larger the shield will grow."

Determined, Cael closed his eyes and focused, channeling more of his magic into the shield. The bubble around him stretched outward, expanding until it formed a protective sphere roughly two meters wide, with him standing at the center.

"Looks like two meters is my limit for now…" he muttered, testing the edge of the barrier with his hand.

After a while of practicing the spell, pushing himself to control its size and strength, Cael finally allowed the magic to fade. The bubble vanished.

Tired but satisfied, he made his way back to his dorm. It had been a long, exhausting day—and now, all he wanted was a good night's sleep.
