HARRY'S POV
The now extinct eastern sects had different, sometimes opposed opinions over almost every subject.
Each had its own philosophy, its own spells, its own artifacts, even their own locations for the meridians.
The only thing they seem to have little to none disagreeing upon is the spiritual realm, which is why while he had, with GAI's help, to collect parts from each text for each subject to piece together his own complete understanding of each subject, while discarding the rest, he had as full understanding as possible.
The spiritual realm is the acc.u.mulation of spirits of every single living being in the world.
It is the hopes, fears and beliefs of everyone that ever lived.
It is, as Harry calls it, the world's belief.
Having said that, every living being also has a small spiritual realm of his own, one that has many names- soul, mind, heart....
The process of doing magic is half of your energy to to push your belief from your own spiritual realm to the world's spiritual realm, and half to manifest it in the physical world.
Saying that, the process to become animagus is different.
The animagus ritual is about changing your own spiritual realm to become a combination of animal and human and then convince your body it's real with your knowledge of the animal before using magic to change.
No matter if it's the original ritual or the potion, the process is about changing you to the animal you are the most similar to automatically, thus doing it with the least resistance and pain.
Of course, the difference between the two is that the ritual creates a less balanced result then the potion, thus making you become more animalistic and your descendants to suffer from the 'Blood Malediction'.
The new ritual works differently.
Instead of working automatically, the person who helps in the ritual is able to direct the spiritual realm toward the wanted animal by being inside their spiritual realm and talk to the person that undergoes the process.
And this was exactly where Harry is right now, inside Nagini's spiritual realm.
He didn't have a body in here, nor did he needed one, what he did need is to convince Nagini's spiritual realm to change into more human-like.
He could see that Nagini had never trained in Occlumency, as her spiritual realm wasn't organized at all.
It was like being inside a little child's finger painting, different colors everywhere, each seem to convey its own emotions and sensations, yet the colors that were seem the most were green and red.
If Harry wanted to convince Nagini's spiritual realm that it is also a human, he would have to create order in the chaos.
He started small, making the everything be organized by colors.
Green and red were in the middle, turning into a big long rope with stripes that Harry quickly understood is her snake part of herself.
The other colors quickly turned into different animals.
Blue turned into a wolf, yellow into a horse, brown into a bunny...
Every parts of what makes Nagini herself turned into an animal, yet non of them were human, and Harry's could see that her spiritual realm is deciding on one when the Black crow was being drown into the snake.
Unwilling to let it be like that, Harry started adding the colors that became animals into the black crow.
Adding the wolf turned the crow into a sparrow, adding the bunny turned the sparrow into a vulture, adding the horse turned the vulture into a hawk.
Each and every color turned the animal into a different one, yet non turned into a human, and the more colors were added, the faster and stronger the pule of the snake was to the animal.
Seeing that there isn't any other option, Harry, unwilling to admit defeat, did the last thing he could, he used his magic to transfigure the swan, the animal that when adding all the colors appeared, into a human form before pushing it into the snake.
The reason that Harry didn't w want to use this method was that there was no say what would happen when his magic is mixed with a person's spiritual realm permanently like it does now that the human form is part of Nagini's spiritual realm.
'Yet, at least the experiment succeeded.' Harry thoughts as he stopped feeding the rune scheme magic and came out of Nagini's spiritual realm.
Nagini was still knocked out, and with Harry's own tiredness because of his magic almost running out, they both just laid on the floor, waiting for energy to return to their bodies.
LUNA'S POV
Waiting for the ritual to finish was unbearable, after working together for a year with Harry toward the goal of curing the disease, Luna felt the wait for results is torture, not like how it is probably for Daphne and her family, but still.
A little bit after the three hours mark has reached when the door from the room opened up and Harry came out with a Indonesian woman in toe.
The squeal of joy that was about to burst out of her died in her throat when she saw Nagini's aura.
At the beginning it seemed she had the same greenish red aura as before only with a small colorful change that could have happened as a result of the ritual, but as she saw the both of them together she saw that the changes in color in Nagini's aura were identical to Harry's changes.
It was like Harry's aura and Nagini's were connected inexplicably.
"Merlin." She whispered as she took a step back. "Harry, what did you do?"
