Nagini's Memories
Inside the iron house where Nagini resides in the Box World, a silvery-white mist permeates the air.
The humanoid Patronus crouched beside the giant green serpent, its ethereal hand gently stroking the serpent's forehead. Peaceful and serene, the entire iron house was devoid of any extraneous sounds, save for the serpent's slow breathing, which sounded exceptionally tranquil shrouded in mist.
Lucien stood aside, observing the Patronus's soothing of Nagini's soul. The Patronus's power was both stabilizing Nagini's soul and combating the curse within it, providing protection for Lucien's subsequent spellcasting.
This period of exploration allowed him to understand his Patronus better. He discovered that his diverse group of Patronus each possessed unique characteristics. For example, the giant serpent Patronus was already the largest, and its size continued to grow as Lucien infused it with magic. He had tried it himself, and even when it was on the verge of running out of magic, the giant serpent Patronus spirit continued to grow. It seemed that as long as the magic was sufficient, it could continue to expand indefinitely, perhaps eventually encircling the entire world—of course, that was still a long way off for him at the moment.
The humanoid Patronus is the most "worry-free," as summoning it hardly affects his use of other magic.
Lucien raised his wand and took a deep breath.
"Obliviate."
A pale blue light emanated from the tip of the staff and gently touched Nagini's forehead.
Originally intended to erase memories, Lucien, through repeated trials, discovered an advanced use for it: to awaken Nagini's strongest human memories to combat the beast's rage. The Obliviate can not only delete and modify, but also guide and recreate.
Lockhart, that fame-seeking fellow, does indeed have unique expertise in memory magic. Whether it's browsing and reviewing memories or modifying and adjusting them, his skills are unparalleled. A wizard's talent and dedication to a specific spell can indeed produce unique effects.
Lucien inherited and improved upon these techniques.
Countless images flashed by in the pale blue light, fragmented and chaotic, like old photographs scattered by the wind. These were Nagini's memories from her human days, shrouded in layers of curses and buried deep within the ruins of her soul.
He saw scenes: iron cages, tents, streets, forests... He also saw figures: brown curly hair, freckles, heterochromia, blue flames...
Lucien saw "familiar faces," but they all looked like they did when they were younger.
Newt Scamander, back then, didn't have gray hair; his curly hair was brown, and he had more freckles on his face than he does now. Beside him was Tina, wearing an American Auror uniform, with a serious expression. And there Dumbledore younger than he is now, with less weariness and world-weariness in his eyes.
Then came a blue flame. The flame almost filled half the frame, burning in the night sky, both beautiful and dangerous.
Lucien didn't examine them closely; the fragments were too chaotic, and delving too deeply might damage Nagini's already fragile soul. He withdrew his magic, and the pale blue light slowly dissipated.
The brief treatment has ended.
The humanoid Patronus released its grip, stood up, and the silvery-white light faded away, disappearing into the air. The large green snake quietly curled up in the corner, its breathing even and deep.
Lucien walked out of the iron house and closed the heavy iron door behind him.
He rubbed his throbbing temples, took out his Instant Whisper from his pocket, and checked unread messages. His fingers slid across the smooth page, his gaze landing on the last message.
The sender was Dumbledore. The message was very short, only three words:
