The day started out like any other for Natsu. Wake up and go hunt food for him and Igneel. After eating breakfast Igneel would have him do his warm up. Carrying a boulder up a down a mountain. But the mountain now was muddy and slippery from last nights storm. As Natsu was carrying the boulder up the mountain he slipped and lose his focus and grip on the boulder. Dropping the boulder and falling down with it down the mountain. As Natsu was falling down he hit his head a couple of times on rocks jutting out of the mountain. Then stopped at the bottom. Igneel came to Natsu after laughing his ass off and checked Natsu for any injuries. Not seeing any he took Natsu to there cave and put him down then laughed some more and fell asleep. When Natsu woke up his head felt clearer and his thoughts weren't just randomly coming to him anymore.

"I see you're awake how's your head Natsu," Igneel asked.

"It feels clearer and thoughts aren't just coming to me."

"Hmm... maybe you will actually get what I'm teaching you now. Anyway, I bet you're hungry let me go get your food. I don't want you walking around with that head injury yet." with that Igneel when and got them food.

While eating Natsu thought of something. "Hey Dad, since you're the fire dragon king, does that mean you could teach me other types of fire dragon slayer magic."

"No, I can't I only know fire dragon magic. A dragon can only learn one type of there variant unless they were born a hybrid but they can only usually use the mixed element. You won't have time to learn that any way you have to learn fire dragon slayer magic, dragon force, fire dragon king mode, and dragon culture before you could learn other magic."

"Dad, I have another question what if I ate another element?"

"Well, it depends if you were to eat another fire dragon's fire you could use their magic for a time. If you ate another element you would probably die but there have been cases where a slayer ate another element by accident and lived but that was few and far between. You could try but you will have the most excruciating death if you fail."

"Really what element could I do?"

"Well, lightning would probably be the best for you since you could handle the heat. Also, it is chaotic in nature that is similar to fire since both of them are hard to control. If you were to do an element with a different nature like the earth which is solid it would most likely kill you from the contrasting personalities but you would have to find potent enough earth first."

"So your saying I will never be able to use earth magic, and how will I find potent lightning if I have to find potent earth?"

"I never said that you couldn't use earth magic just that it would kill you if you ate the raw form and tried to use dragon slaying magic with it. Also, lightning is always potent if it comes from storms."

"So I can use other magic?"

"Yes but after all the fire dragon slaying magic."

"Dad is their other slaying magic."

"If a creature teaches a person to slay their own kind then yes there are others. If you run into another type of slayer be careful. The god and devil fire slayers fire could hurt you since they are the flames of purity and darkness. but if they were not taught by the actual kind then you could probably eat them."

"The final question I have is when where you going to tell me that I was END?"

"So you gained your memories of how you were created. Well, I was not going to tell you. You are Natsu Dragneel you chose who you are."

"Thanks, dad but do I have to kill my brother. Wouldn't that kill me?"

"No, it wouldn't kill you as long as the book isn't destroyed you will live as long as your natural life span permits after he dies. Zerf created it that way for only you and the demon Sayla.'

"Why that demon specifically."

"She is the keeper to your book and the one who would take care of you if Zerf accidentally kills you."

"So could I also train with my curse?"

"Actually what is your curse. I was never told by Zerf what exactly your curse was?"

"My Curse is the ability to use any fire slayer magic but I have to go open my book but I can only learn one type of slayer magic every three years."

"How are you going to open your book?"

"I can summon Sayla apparently."

"Okay then if you want to I won't stop you but you might overwork your self if you try learning two different types of slayer magic."

"Don't worry Igneel I will not slow me down. Okay, here we go." Natsu held his hand out and thought of summoning Sayla. A magic circle formed under Natsu then a bright light appeared. Once it dissipated a female appeared next to Natsu.

"Hello, master END how may I be of service?"

"I would like you to open my book so I can get a new slaying ability."

"Okay master but I have a worn you. The book takes three years to charge to get another slaying ability. Also, It won't let you take another slaying ability until you are proficient enough in the one you were given or slay a creature with that given magic. The book will glow when both of the criteria have been met."

"Okay then let's open the book."'

"Okay, Master the book will tell me what you got. Let's see you are now a Phoenix Slayer."
