A New Mission, a New Name

(10 minutes later) (Also I will now refer the trio as C, S, T respectively cause I'm kind of lazy) Third Person POV:

They arrived at their destination. They walked inside of the building. After showing their IDs they were allowed to, meet the Principle. He was not happy. In fact, he looked quite disappointed. The room was the same as last time. Although, it was a bit messy.

"I'm quite disappointed in you two," He said. T and S were ashamed. Although you couldn't see their faces.

"... We're sorry," They both said at the same time.

"You know the quote. Don't say sorry. Do better." The Principle stated.

"What about me?" C asked.

"Good job." The Principle replied ,"Anyways, I prepared a mission for the both of you. Circle this will be optional"

"K," C said.

"What's the mission?" S asked.

"I will inform you 3 later." The Principle replied ,"Anyways, since you guys are taking the mission, you will have to go to the outside by tomorrow morning."

"Yes, sir," Everyone in the room expect the Principle said.

"Here are 3 cores. They will mask your abilities. So, put it on when you go out" The Principle said as he handed out 3 gem looking objects. The cores were in different colors. He handed the yellow one to C, the blue one to S, and the red one to T.

""Kay/ Okay/ Yes, sir,"" C, T, and S replied in unison.

"You may leave," he replied as they left the room one by one ,"How tried some." C was very ecstatic. Why? Because now he could go to the outside more quickly and the Principle was proud of him. S and T on the other hand... not so much. At least they won't have to deal with the Kids anymore.

(Some time later)

C, S, & T were packing their things up. They've never went to the outside expect for special missions. Even when they go outside they've never really explored it. Which means that they've no clue what the common sense was there... (Oh, I hope that no weird situations happens because of this.) Anyways, that means that they have to learn some stuff about the outside. There's only one person that comes into mind... The Teacher. (!Warning! Info dump)

"So, you guys want me to tell you about the outside world?" The Teacher asked

"Yeah." T, S, and C replied.

"... Fine, just this once. First of all, you guys are OP." The Teacher stated ,"Almost every living thing has these 'dreams'. These dreams grant you powers and stuff like that. If you have dreams then you have a core. The core allows you to use these powers.

There are 13 classes. 13 being the lowest and 1 being the highest. Being in class 11 means that you're an average human. 12 and 13 are usually normal animals and plants. Class 10 means that you are above average. Class 9 means that you can hunt nightmares. Class 8 means that you are stronger than the usual class 9. Class 7 means that you're stronger than class 8 and etc. until class 2. Class 2s are basically celebrities They are way stronger than class 3 or anything below. And then there's class 1. Their gods at that point. But, their are rumors that there's a class for people that are above class 1. They are nicknamed 'class EX'. Although, there is no proof that these beings even exist. I'm sure you guys know your place in the classes.

Nightmares are corrupted dreams. These nightmares make you turn into monsters. They are generally stronger than normal. They also lose their sense of self unless your a class 2 and up. They are the reason why we are in a post-apocalyptic world for about 70 years (The exacted number is 69... What a beautiful number).

Class 13 and 12 are stronger versions of an animal or plant. They attack anyone that's weaker than them and then consume them to grow stronger. They can be dealt with by a class 9. Class 11 to 3 are pretty strong and can only be dealt with by a class 9 and higher. Class 2 and up are monsters that have self awareness. There are no records of a class 1. But, if a class 1 appears and tries to kill everyone while all of the class 1s that are not corrupted don't help, well humanity is pretty much dead.

Then there's the Holy Council. The appeared around the same time nightmares appeared. At this point they've taken over the world expect for the places were nightmares live. It's kind of a cult were the try and cleanse the world from nightmares. The also have their own Kingdom. Fun fact: the classes were made by the HC. Because the HC has pretty much taken over the world, every Kingdom uses these ranks.

The areas that nightmare live in are divided in different ways but, we'll go with the Elysium's way. There are 5 areas. As you guys know we are in Tartarus. The place ruled by class 2s and filled to the brim with nightmares. Then there's the Field of Punishment second by Tartarus about how dangerous it is. The Mourning Fields have less nightmares than the Field of Punishment. The Asphodel Meadows only have nightmares that are classes 11 to 7 there. And the there's the Entrance, there's only 13 to 12 there. Perfect for newbie Hunters.

And on that note, Hunters are people that hunt nightmares for a living. The HC 'owns' most of them. It's the kind of job that can get you easily killed but, there's a lot of money that comes with it due to the fact that cores are sold for high prices. Even class 13 are sold for $100000 or something like that. The quote 'High risk and high reward' fits the job quite well.

Oh, and there's also only 7 Kingdoms if you count the HC and the Tribes. Any, question?" C, S, and T all raised their hands.

"... This is going to take all day. Isn't it?" The Teacher muttered. (I'm not going to write the rest of the conversation because, 1. it's already a big info dump, 2. I'm lazy, and 3. it's easier to explain why something has changed because I'm defiantly going to change my mind at some point.)

(2 hours later)

"Is that all?" The Teacher asked.

"Yes, sir," S, C, and T replied.

"Phew, good," The Teacher sighed ,"You guys should continue on preparing."

"K," C replied. The all went to their separate places. The Teacher was going to check on the Kids... Hopefully they won't be a pain in the ass for him.

(Le next day)

"Come on let's go!!!" C exclaimed with sparkles in his eyes.

"Coming, coming," T replied sleepily. It was 4 in the morning. The spent around 6 hours trying to pick clothes so that they didn't stand out too much, getting things that a "normal" person would have, getting history lessons, and etc. After they got breakfast and S got coffee, they got on a boat.

"You're mission is to steal 3 class 1 cores," The Teacher ordered ,"I will be guiding you on how to live in the outside. And make sure you wear those cores that mask your abilities."

"Okay!" C said excitedly

"The details about the mission will be given to you after the trip there." The Teacher said ,"You will now refer to me as William Smith"

"Ohhh, those that mean that we will be changing our names?" C asked.

"Yes," Will replied.

"Well, them I'm-
