Obscurus Core

"Gray look!" Gray with Perona walking in the street leisurely ready to find a place and rest...

Suddenly Perona found a picture on the wall she walked by and said to Gray with a weird smile on her face...

This was a picture, of a few wizards looking like detectives, standing in front of the bank while many angry goblins looked so ugly screaming... With a few words under the pictures... [The Ghost thief!]

Looking at this picture, Gray also smiled...

What made him smile more was the picture beside this one...

This time it was a picture of the ministry members with angry faces, threatening with big words about something...

So what was happening here?

As said, Gray wanted to collect things...

So naturally, his first thing was the big places that keep things...

Perona has such a smile because this time she was his crime partner and both of them sneaked to many places and left nothing, even if it was useless they stole it...

And this started from Hogwarts...

For example Snape's herbs and potions collection, or Dumbledore's weird collection in his office, They didn't let go!

For this, Gray felt more like revenge... He even wanted to steal Dumbledore's bird... But the phoenix, this creature, won't leave his master's side, till the master life came to end... So Gray gave up... And honestly, he doesn't want to take many creatures with him... After all, it will be a trouble to take care of them... And his ring even if it can give a perfect world like condition... He still felt weird about this...

So after some thought, Gray only looked at the ready to use things and took them...

And like this, Many magical things disappeared from Hogwarts, especially things related to alchemy and potion creating, like herbs, and materials...

As for the ministry, this place was simply a cave of weird collections... Many things can be found there, so Gray sneaked again and cleaned their bags...

And the banks, it wasn't Gray who stole it, but Perona by herself... Speaking of... Gray created a new mark inspired by Voldemort's death mark...

The death symbols, this magic was originally Voldemort's creation... This dark lord was really a genius...

No wonder he has [Creativity] Attribute...

This mark has a few uses like summoning the death eater forcefully, torturing them when he has nothing to do, and communicate with them...

It's more like Voldemort was marking his own slaves...

And Gray made a new mark taking an example on this mark idea...

But Gray's mark was many times simpler... It doesn't hurt anyone, nor forcing anything... it's more like a key... And unlike the original mark, his mark doesn't have a form and it can be removed as long as the marked one wanted to...

All this mark does, is to connect the marked one with the castle space...

So Perona can use this mark as a store ring, to send what she wants to the castle, and even if she wasn't beside Gray, as long as she wasn't very far, she can teleport directly to the castle...

So Perona turned this mark into a crime artifact... And sent her ghost to steal all underground holes under the bank directly filling their collection with many things...

Speaking about the bank, every time Gray sees the doubling charm on the treasure there he felt little bad...

In this magical world, there is a charm called doubling charm... And is it called, it can copy things...

But its failure was that what it copies were almost like conjured things... No real attribute in the copied object...

For example, the copied food won't give the body more nutrition. Nor the copied potion ingredients can be used to create a potion...

Seriously if such a thing can be done, what was the need for money?

So he couldn't use it as an unlimited material maker...

Even though there were many other uses, it's still somehow worthless if it can't copy a real thing...

Back to the point...

After seeing Perona using the mark like this, Gray completely left the thief job to her...

One power system might be balanced, but when two kinds of powers merge together, many things that shouldn't happen will happen... Perona was the best example... Her fruit ability with magic told broke the balance of many things...

So, that what happened since they left Hogwarts...

After thinking of all this, Gray smiled and didn't care about this anymore, anyway they are leaving soon... When the ministry finally realizes that it was them, it will be too late...

Now he was thinking about how to deal with what he got today...

While walking soon Gray and Perona went to where they will stop today...

After entering the room, Gray sit down while Perona directly entered the ring, and even Nagini did the same... For their reaction, Gray didn't feel weird and also entered his own castle...

...

...

Inside a dreamy tremendously big castle that was almost equal to a small city-size...

This castle can't be called a castle anymore...

The ceiling of the entire castle was a cosmos, filled with stars, while the floor was more like walking in a crystal void... If it wasn't for the light and some of the decorated walls that were made of crystals and dark gold and many other materials giving a very thick sense of mystery reaching all the way to the stars, one won't link it with *castle* word... But more like a palace in the center of the stars...

This castle was Gray's ring castle after countless transformations, space Extensions, modifications, and atmosphere changes...

Gray always liked the ceiling of the dining hall... so he simply modified his ring castle ceilings to it...

With many magic skills and knowledge Gray naturally can do this... And as his test subject, he chose his ring castle...

And the result was so satisfying! Even though he has somehow overdone it and made many awkward things in the castle...

But he can say, that his castle has everything at this moment! For example, some rooms he made were like small worlds, water world, jungle world, frost world, even a cloud-like world...

There is even a world filled with Gold!

A gold sea that he can't see its end... Not fake of double gold... But a real gold... Which also the reason why the goblins were mad...

Gray will visit many worlds after, so naturally, he won't steal every time... He doesn't want to be a poor traveler...

Even though there weren't many uses for gold, almost useless... But since he got the ring, Gray found that it's fun to collect things like this...

Now, this room only misses a dragon to claim to be the king of the room... And it will be perfect...

(Author: King of the room... What a cheap king...)

All in all, Gray didn't leave anything and tried many things inside the ring castle, and this was the result... He upgraded his ring castle to a dreamlike world...

To tell the truth, the castle limit somehow surprised him... It can be said, that there is no limit, and Gray felt some changes in the castle after upgrading it like this... Had to know that the castle was actually a source he used for the ring, So naturally, it should have a way to develop... It's just how and which way of development the castle will take, Gray doesn't know... And won't try to make it bigger to know... For now, it was already big enough...

In the main hall of the castle...

This hall, unlike the other rooms... there were many pillars everywhere and was so huge!!

In the center of the hall, Gray with Perona and Nagini stood in front of a magical bubble containing a very weird black cloud...

"%^@#%@$" Nagini had an odd look on her face while looking at the cloud in front of her and didn't want Gray to get closer to it...

She knew how dangerous this cloud was...

Obscurus... One of the darkest and most powerful magical creatures in this world...

How to say it... This thing can't be called a creature in a real sense... But a force... a parasitical magical force...

The Obscurus developing condition was somehow special... when a young wizard or witch awakens their magic at a young age and being forced to suppress their magic through psychological or physical abuse... This thing will appear...

It was such a dark condition...

Even though the Obscurus in front of them was extremely weak... But still, it wasn't safe in Nagini's mind...

Gray knew why Nagini was so worried, after all, she has a long history with this thing...

But Gray calmed her down and told her not to worry...

This Obscurus in front of him was just a force without a host... The Obscurus Newt collected and kept alive all these years...

A few hours before, Gray found the old Newt location... But didn't try to get closer to him... Anyway, Newt was just a stranger to him, So Gray simply took the information about the Obscurus with the Obscurus he hid and left silently...

Gray got the Obscurus only because he was interested in this thing... He wanted to see if he could use it...

So Gray with Perona and Nagini tried a few things and kept studying this weird thing...

Till finally, Gray found nothing can be done...

The original host already died...

And it was originally a parasite born of the original host magic power... so naturally, he can't simply put it inside someone else...

But as if thinking of something, Gray covered his hand with Haki and seized the Obscurus...

Looking at the dark smoke between his fingers struggling to reject the weird object that suddenly entered its domain...

Gray raised his eye with interest... So he extracted once to see what kind of attribute will this give him...

But after doing this he regrated... Because Obscurus actually became crazier and actually activating its power...

Seeing the reaction in front of him, Gray also saw what attribute he got...

[Obscurus Core]

Seeing this attribute, Gray understood that he extracted the most essential attribute of this Obscurus!

*BOG* With a bubble breaking sound, the Obscurus rushed Gray, which scared Nagini and wanted to use her fire to destroy the dark cloud...

But Gray didn't care about this... In his eyes, it was more like a dying struggle reaction... Because he found that, it wasn't activated, but actually losing its power...

Even before it could reach Gray's body, the black cloud dissolved by itself, and not even mist was left behind...

This was beyond what Gray expected...

"Gray!" "@$%@$#" Perona and Nagini looked at Gray and asked...

"Don't worry, as you have seen... It was destroyed... "Gray touched Nagini's head and said with a smile...

To be honest, Gray had some things he wanted to try... He didn't expect to extract the core of the Obscurus like this...

But that good either... Since the core was extracted, he can still do other things with it... In sense, this core is more valuable than a complete Obscurus to him...
