Experimentations an dragon eggs.

Time passed quickly and another two months passed. Luna finally found the right combination that solved every problem with magical interference! Her rune cluster worked as a magical stabilization, causing the magic in the surrounding area to become less chaotic in nature. Her research led her to believe that the interference is being caused by the magic affecting the laws of physics around it due to it roaming free without anything guiding it. This actually came to her mind when the trio accidentally found out that Konrad's magic actually doesn't affect electronic devices. She came to a conclusion that thanks to Konrad's superior ability in magical control the magic he wields does only what he wishes it to do without loosing power to affect anything else. Just like a starship can go infinitely faster without the air resistance, the magic of Konrad is getting infinitely closer to perfection the more he controls it, causing the spell to not leave any wastage. Luna's rune cluster causes the magic around it, in a specific range to become stable, causing no interference with the surroundings. If a spell is shot through the affected area, it would stop leaving any magical leftover whatsoever, becoming a perfectly stable spell which would only perform the intended function and dissipate into the atmosphere as a stable energy, as long as it stays in the area affected by the rune cluster.

Konrad also found out that performing spells in the affected area sufficiently helped in the personal training, helping a person to naturally cast stable magic. It greatly increased the speed of training the magical control in a similar way a child learns to ride a bicycle while being hold straight thanks to the stick in the back hold by the child's parent. The trio wondered if they should install the runes in the entire castle but decided to postpone it and for now put it only in ROR, the Lab and their dorm to secretly help their roommates.

Hermione also cracked the ritual magic. She finally translated the language of magical formations and managed to substitute a rain summoning formation using only rune clusters of Luna. She could now find better ways to improve the efficiency of the old magical formations and it allowed her to create and modify her own formations! She could now for example improve a formation that couldn't fit any more symbols by swapping them with the corresponding rune clusters etc.

Hermione's research helped Konrad as well. Konrad's work on alchemy and the Philosophers Stone, was mostly based on old magical formations. He knew how to change lead into gold but it was really inefficient. He needed to supply a lot of magic power to the formation with the stone as the focus and a conductor only to change a kilogram of lead into a hundred grams of gold. It was a loss of so much material! 'Well at least it looks kinda cool..' Konrad thought.

The process of transmutation started with Konrad supplying mana into a big formation with the Stone lying in the center while two pentagrams were engraved on the floor on the left and right of it. On the left one the lead was placed. When the magic was supplied the formation glowed white light focusing in the center, where the stone lied generating crimson energy. The lead would then star to disintegrate into sparkling silver particles that would fly in a wisp straight through the stone and exit on the other side with their color changed into golden only to land on the other pentagram forming into a shapeless lump of gold.

Thanks to hermione the formation became improved causing the the output of gold to increase by two times while the cost of magic energy was eased slightly. But there was still something missing! Konrad soon found the likely reason. The stone itself!

Konrad spend another few days pondering about the problem when a new distraction came to be. Hagrid had a dragon egg!

There were many rituals involving dragons, but most of them balanced on the line or were completely dark. But there was a ritual that the trio found in the Room of Hidden Things that was actually too perfect to be true. It was found in a book written entirely in the parseltongue and it depicted a way to obtain the ability of said language! The ritual formation was huge and it needed a hatching dragon as the core of it and a snake willingly wrapped around it while being performed in a highly magical place by at least one virgin.

Soon enough there was a dragon egg in the ROR, that needed Konrad to simply cast a portable fidelus on the egg when hagrid didn't look and then Konrad could even carry it over his head and people wouldn't see it. The formation had to be improved a little to accommodate all three of them but hermione and Luna were up to the task.

Thanks to a few spells they read about they could tell precisely when the dragon would hatch so they heat the egg in the Lab and only a few days later the time came for them to proceed with the ritual. Because of how ridiculous the rituals requirements were, it only required enough magic to work, mixed with the unique magic aura of a hatching dragon ,a virgin and a snake wrapped around a dragon egg. 'Really...how someone came upon this idea, I have no clue. But if it works I won't complain.' Konrad thought.

The egg was about to hatch, so the trio touched the egg while Cristal wrapped around it and everyone started chanting in an old language. The formation gloved purple around them and then the egg cracked! The color of the formation changed into deep green and the girls started hearing hisses around them that came from Cristal whose eyes also gloved green. Konrad on the other hand heard what the snake said and it was the same chant the trio did just a moment ago. Then the dragon opened more of its egg and Cristal turned to it, when it peeked out. A zap between the eyes of the two reptiles caused the dragon's eyes to glow green as well and then the snake simply looked at both Luna and hermione and each time their eyes met a string of information came into their followed by short pain in the head. The dragon didn't even spare Konrad a second glance probably because he already knew parseltongue. Soon the light from the formation and the dragon faded and everyone other than Konrad lost consciousness.

When they woke up they found out that each of them could now understand Cristal and they were really happy with the new ability. The dragon was send to the lab because... why not? It can become useful in the future. Of course they had to make the place suitable for it but somehow Luna had a hand with the Dragon that she called Ruby not caring for its green coloration. Ruby always become calmer around Luna and to everyones surprise, a familiar bond appeared between the two around three weeks later! Cristal and Ruby quickly hit it of but Athena wasn't entirely pleased of the new addition, while Crookshanks didn't particularly care. They kept Ruby at the Lab and always Brought here to ROR whenever they were there.

It was a really big surprise for everyone when some time later Cristal walked over to Luna with Ruby and everyone heard a single world in parseltongue from the not so snake. "Mommy!" Said the little dragon.
