Chapter 1

It was a normal day of September in Amity Park. With the summer heath drawing back and it being somewhat cloudy, every thing was as like it usual in this little town.

Danny was on his way home, alone. His friend Sam was busy by forcing his other friend Tucker to the library, where she planned to force him to read all books they had on poesy. Really, Tucker should have known better then to first criticize Allan Poe just to be caught that he haven't read any of his poems, or any other authors poesy either. So his friends where not with him as Sam was torturing Tucker with litterateur.

Laughing a little at the memory of when Sam started to interrogate him with questions about well known litterateur and their authors. She even shot some of them on Danny, but luckily he only ended up getting them he know a good enough answer to satisfy her. Tucker did not. He also had the bad timing of it being in the beginning of their longest break, lunch break. Effectively laying way for his own doom. It probably wouldn't have gotten so badly on Sam's temper if he hadn't tried joking about some of those famous works.

Danny, who was safe from Sam's wrath, didn't really have anything to do on his own, so he had decided to head for home. A thought about try to do work on some of his school assignments came to mind but got put down as he didn't feel like it. But it may end that he will have to anyway if Jazz sees him. Danny loved his big sister but wished that she wouldn't be so strict on her idea of studying.

Knowing that his grades is dropping she have become more and more adamant in that what was needed was more studying. Nothing against studying but he was just so tired most of the time, that it just ended on second hand simply. Honestly, most things have ended on second hand as of late.

He didn't get more time to think about it as someone yelled down on him. "Ghost-child. Today I will have your hide."

And as any normal day of Amity Park, there was ghosts that demanded fighting. Hurried in to an empty alley, Danny shifted over to his ghost form and flew up to the imposing ghost known as Skulker.

"Really Skulker. Do you have nothing better to do, nothing at all?"

"Quiet child. I am the greatest hunter there is and no prey can get away from me." He pulls one of his guns at Danny, charing up. "Any last words?"

As he shot off Danny tests something that he been working on for some time, a shield. A green semitransparent round wall come in to existent in front of the boy seconds before the energy charge could hit him. And aside from some small cracks, his shield hold, leaving his opponent staring angrily at it and him.

"What is this cheating? Since when did you make energy hardening?"

"I have been training on it."

Skulker hissed. "I had believed that your core wouldn't accept that energy form, I had hoped it wouldn't with how it is a pure defense tactic. But apparently, I was being optimistic the chance of your core being a fight core and not a protection one." He shock his head. "No matter, I will still have your hide." And he resumed to fire off shots at Danny.

Naturally, Danny dodged them. But he didn't attack at his opponent as he normally would. What Skulker had confused him. It took for Skulker to manage a shot at him that pushed him down on to the ground before he pulled himself together again.

"Are you mocking me ghost-child?"

"No, was just thinking on something else."

With that Danny started to fight and soon Skulker was down in an dark alley with his armor failing on him. And with the ghost boy standing over him but not doing anything other then looking at him. Waiting a moment for his usual taunting before pulling him in to his thermos, but none of it came and Skulker was fast losing his temper.

"What are you waiting for brat?"

"What did you mean?"

"What do you mean 'what did you mean'? Brat, I am wondering why the hell you are standing there doing nothing."

"No, not that. I'm asking about earlier, what you said about my core. What did you mean?"

Skulker stared at him for a minute. "You are what, a year old now? And you still don't know what a core is."

"I know what a core is, it's our 'heart'. But what was you meaning with 'hopping my core was an fight core'? I know that my core is an ice core and I have used it often enough for others to see that."

"That is what type group it is. I was talking about its class category."

"Type group… class category?"

"Have no one bothered with telling you about this, none at all?"

"N-no, usually it is all about who can hurt who most and after the whole heart and ice part I thought that was all to it."

"Still, there should have been someone in your beginning of death to tell you about this."

"But I never died, not fully at least. And I didn't even go in to the ghostzone until a month or so after the accident."

Skulker gave a face that told he was pondering it. "Hm, that most likely why. Okay, I will give you the presentation then but listen closely because I won't tell it twice."

Danny, for once obediently, sat down in front of Skulker who pulled himself up to sit more comfortably against the alley wall. Skulker started the explanation that all ghosts gets on their death day, or a day close after it, about being a ghost. It was like a school lecture, going through all basics. What a ghost is, what a death-day is, how a core is a ghost's heart, why you shouldn't use your core for either cooking or storing food because it is not a kitchen utensil, neither is it a music-box or instrument. There was also more advance information that was harder to understand and Danny did interrupt Skulker a few times to ask questions. Skulker didn't get annoyed by it at all as he simply answered any question, told him it was okay if he didn't understand it all at once, that he should give it some time to sink in.

Lastly, Skulker went through about types and classes. "The type group is basically what your core is using as it component. To these components there is also different forms. My own core is of a passive form of 'electricity', it allows me to charge and control my suit but because it's passive I can neither shot of electricity or directly take control of mechanical objects and build them to something else."

"Like Technus."

"Right, because he is a more active form of the electricity type but not as active as, for example, Plasmius. The number of forms is basically passive and active. Those that are between those two are usually seen as neutral forms. Your own would be an active ice type core."

"Now to class categories. While the component is what makes the core it is the class that gives the core its focus and makes the core function. Like how humans need that their brains send out the signal to have their hearths going. An explanation on what a class is more exactly would be to say it is our obsession, or rather, where a ghosts obsession come from. The core need a 'will' to work and that is its class, while it may seem like there is an endless variation of obsession, in truth there is not."

"In all class categories there is a number of variation that fits in. For example, Ember have an attention class on her core but is in the variation of admiration, where she needs someone to respect or simply admire her. An other in the same class but different variation is Ghostwriter who have variation acknowledge, where he need to make something that can be shown and give him creed. Different variation and different obsession but still the same class category."

"Okay, so type is what energy the core is made of and class what keeps it going. But what was you talking about earlier about my shield? How does my class have to do with that, isn't it something that have to do with type?"

"What class your core is have more importance then just keeping your core function. It determines what abilities you can use. Think on it a little, Ghostwriter and Ember that have different types but same class, both uses their instruments to their obsession to fight. Writer with his books and story telling and Ember with her guitar and music. While Technus and Plasmius that are of the same types but with different cores can not use the same kind of attacks or defense. So while our type gives the form of energy to our cores, it is its class that determine how we can use it."

He looks to Danny who is sitting quietly with a thoughtful look. "So you think you got it?"

"Yes, I think."

"It's fine if you need time to sort it out. Everyone needs that after they are given this lecture, it's normal and natural."

"Okay. Thanks for telling me this."

Skulker huffed. "You should have been given this to start with. It is important to inform new ghosts these facts as it for some isn't fully clear what type, or worse, class they belong to. If you want more information you can find it in either the library or at the jail in the ghostzone but you should now already have what is essential." The adult ghost gave a sidelong glance at the child. "It wouldn't be to much to ask for you to not use the thermos in exchange for the lecture, right?" He tried a hesitant smile.

"Sorry Skulker but I still have to take you back to the ghostzone." And with that Danny trapped him in his thermos, all while Skulker was cursing.

After that Danny shifted back and went on home. Feeling mildly surprised when he noticed that Skulkers lecture had taken a little more then two hours, making it near 8 P.M. Jazz was siting in the living room area and saw him almost instantly when he came in.

"Hey Danny, dinner will be in an hour. Good of time for us to work on your school assignments." Meaning that he would be forced to sit still at his table while she hung over his shoulder, directing and righting.

He gave an involuntary shudder while walking upstairs after his sister, who was already verbally lining up her newly out planned study schedule for him. Feeling helpless while walking in to his room and setting up for an hour of fruitless study.
