Igneel had no clue what to do. Should he tell him, or should he try and avoid the question. He knew that on a topic such as this he couldn't just brush it off. He had to tell him, but what would Zeref do. Would he be angry? Igneel knew Zeref didn't want Natsu to know that Zeref was his brother. Igneel thought about it for a second before he caved and said, "Zeref is your brother. The two adults are your mother and father, and they are dead. Your brother resurrected you as a demon, that is why you were floating in the egg thing. Your full name is Etherious Natsu Dragneel or E.N.D, but you cannot tell anyone this. Your parents were killed in a dragon attack, along with you. Once you return to society, you must never tell anyone about you being a demon or you being the brother of Zeref. You are never allowed to see Zeref as he is seen as evil. If anyone finds out you are related to him, you most likely will be targeted, and people will want to kill you."

Natsu yelled, "But I can't be a demon! I'm human!" Igneel sighed, "You are a demon, and you have to accept that. Zeref never wanted me to tell you, but he said that if you found out yourself I was allowed to tell you. Just know that if people know you are related to him, you will be in grave danger, and although you can go up against most dragons without much effort, there are some dragon slayers who even could go up against me, and they will try and kill you." Natsu frowned, "Okay, I just wanted to know who they were."

He then got excited, "If I'm a demon, does that mean I have special power?!" Igneel looked at him with a smile. He knew how quickly Natsu could lighten a sad mood. He said, "You do have special demon powers, but I don't know how you can access them as I am a dragon and don't know anything about demons." Igneel then lost his somewhat happy mood as he said, "I may as well also tell you about the eclipse project-" Natsu interrupted, "What is the eclipse project?!" Igneel roared, "Shut up and listen brat and you will find out!" Igneel said in a calmer voice, which was not that much calmer given who he is, "The eclipse project is something that me, Anna, Zeref, and 4 other dragons created. Zeref created something called the Eclipse Gate, which is used for time travel. Acnologia is a very powerful dragon. Me and him are about equal in strength. In the future there is a much higher concentration of ethernano, which would mean that you would be much stronger in the future than you are now. The 4 other dragons are also training dragon slayers. They will send them into the future to where they will be stronger, and will then kill Acnologia."

Igneel switched to a much more serious tone, "You however are much more important, as Zeref created you for one purpose, to kill him." Natsu's world almost fell apart. He was created by his brother to kill him. He didn't know how to react. He didn't want to kill his brother! Natsu protested, "But I don't want to kill my brother!" Igneel said, "That is why I didn't want you to know. One day you will need to kill him, I'm sorry. I know that you will say that you don't want to kill him, but that is also for the good of the rest of the world. Everything dies around him, completely unintentional, that is why you must kill him. Your brother wants to unleash your demon power which would force a killer instinct into you if not controlled, in which case you would kill him. I just hope you fulfil his wish, one day."

He said that last part rather quietly, but Natsu said, "Dad, I don't want to kill him! I have never killed a person before. Sure I have killed dragons, but never a person!" Igneel said, "One day you will discover that not all humans are good, and in fact that majority are bad. You will then understand why you must kill, sometimes. I also want you to know that killing a dragon is no different. That was a perfectly intelligent creature just like a human, but because I told you to do it, you killed it. I want you just to understand this, one day." Natsu said, "I will understand one day, but I can't bring myself to do it now. I couldn't kill another human!" Igneel said, "But you are a demon, and not a human. Just remember that."

Natsu asked one last question, "You said something about sending me into the future. What year is it?" Igneel paused. This is what would seal the deal of Natsu knowing everything. He then conceded and told him, "It is the year x350." He then said, "Now get to bed brat!" Natsu was surprised in his change in mood, but it wasn't all that surprising. Igneel lied down, and Natsu curled up under his wing, not knowing that this would be the last night that he slept like this with Igneel.

The next morning…

Natsu awoke in his cave. He looked around and found that Igneel was nowhere to be found. He saw w white scarf with a scale like pattern on it, to which he picked it up and wrapped it around his neck. He sniffed the air and could smell Igneel had left the cave he assumed that he had gone early to get breakfast for Natsu, so he plopped himself down on a stump, just outside of the cave as he waited for Igneel to get back. Natsu then noticed his scent starting to fade, and he knew this was strange because it should remain there as he was living there. Natsu then heard roaring in the distance. He heard 2 different ones. One much more sinister, where as the other one was from Igneel.

He ran as fast as he could in that directing, destroying everything in his path to get there as fast as possible. He came to a large scorched clearing without a sign of life in sight for at least 5 miles. He saw in the centre of a large creature to large dragons battling. There was a crimson red one laying on the ground with a black and blue one standing on top of him. The black and blue one had a rounded head with 4 elongated plates coming out of it. He had a plate covered body, rather than igneel which was covered in smaller scales. He had a white underside, with large black claws on his feet, and a stinger like tail. He had cold silver lifeless eyes that added to his evil appearance, as well as the blue tribal marking on his back.

The dragon charged up a breath attack as it prepared to kill Igneel. Natsu sprinted forward, using his magic to propel him at it as he activated dragon force and his normal orange flames changed to a golden colour. The black dragon stopped his attack. He said as Natsu approached him the dragon roared, "I thought you would be stronger E.N.D!" Natsu got closer but Igneel yelled, "Natsu! You can't defeat him!" Natsu hesitated, but this gave the black dragon a chance as it delivered a swipe to Natsu with its large claws.

Natsu did his best to dodge the attack, but the bottom of his claw grazed him. Well grazed isn't the right word as it ripped up his torso and across his left eye, making him blind in his left eye. He then saw the dragon charge a breath attack again and release it at Igneel. Natsu's world slowly shattered at the breath attack approached Igneel, and Natsu couldn't do anything. He was in too much pain to move. He tried to raise his body to his feet, which eh managed to do, but he was too late. The breath attack approached Igneel and Natsu yelled, "Igneel!" The attack hit straight on, as the black dragon rose into the sky and flew away, leaving Igneel in the crater.

Natsu ran over to him as he looked at Igneel scorched body. It had changed from a shade of read to a dark shade of maroon. He walked over to his scorched body and saw his almost lifeless eyes. Igneel said, "I'm… sorry… Natsu…" The life then left his eyes as he died. Tears streamed down Natsu's face as he yelled, "Igneeeeel! Why did you have to go!?" Natsu fell to his knees as the ground became soaked with his tears. Igneel then began to start disappearing, but instead of evaporating, he transformed into crimson flames as they rushed at Natsu, encircling him. They started merging with his body, as a large glowing dragon tattoo formed on his body. It looked like it wrapped around him as it's head came up to his eye, and where the eye of the dragon would be, is where his right eye was, which started to change its colour from white to a glowing orange colour with a black slitted pupil.

Natsu looking towards the sky with his one good eye, as the tattoo continued to glow as it looked like it rad red fire itself flowing through it said as he put a fist over his chest, "I swear, on my title of the fire dragon king that I will hunt every dragon in the world until none remain and this will never happen again!" His tears stopped streaming as he remembered what Igneel said about it He stood up and walked away, leaving a trail of scorched earth behind him.
