Prologue

Natsu Dragneel is a Dragonslayer raised by the fire dragon king, Igneel. A kindhearted and powerful mage, Natsu cares for his friends at Fairy Tail and sees them as his family. He's never questioned who his human parents are, simply telling anyone who asks him that he was raised by his dragon father Igneel. Little does he know, he is sibling to the most evil mage in the world, the Black Wizard Zeref. When Emperor Spriggan, an alias that Zeref uses to hide his true identity, threatens to invade Fiore and take by force the Fairy Heart, Fairy Tail is forced to defend its home and its property. Natsu bravely declares that he will be the one to take on Zeref and rid the world of his evil. Ironic, as this was exactly what Zeref was planning; to have Natsu fight him. Zeref will most surely reveal to Natsu that they are related, but how will Natsu be able to cope with the fact that his only real family in the world is the Black Wizard, Zeref? Or will he simply call Zeref a liar?

Chapter 1: The Secret and the King

The heroic wizards of Fairy Tail fought with all their might against the forces of Alvarez, defeating 3 waves of enemies including eleven of the Spriggan 12, leaving only Mage King August who hadn't shown up yet. Eventually, the royal army of Toma E. Fiore, King of Fiore, finally arrived, offering assistance to Fairy Tail against what seemed like the last wave of Alvarez troops. The battle was easily won by Fairy Tail and the royal army as there were only a couple hundred Alvarez troops left. After making sure that there were no enemies left, Toma himself came out to meet Fairy Tail in the inner circle of Magnolia city, the main battleground of the fight between Fairy Tail and Alvarez.

"And exactly why is an enemy army attacking one of my cities?!" Toma all but yelled with an irritated look on his face at Fairy Tail.

Makarov walked over to the King of Fiore and bowed, as is custom. "I'm sorry to have to drag you and the royal army into this mess of ours, your majesty, but Emperor Spriggan of the Alvarez Empire has launched a campaign to steal something very important of ours and we -"

Toma interrupted Makarov mid-sentence. "Unless this something is so very valuable to Spriggan that he'd send an entire army to retrieve it, then I don't understand. Care to explain?"

Not exactly sure what to say, as the secret of Fairy Heart was not something Makarov wanted to make public. "I can't say, your majesty..." he admitted.

"Makarov, you know I am a reasonable man, but I cannot be reasonable if you continue to withhold this information from me!" Toma told him, a look in his eyes that said I want to help you!

Makarov considered this for a second. "I'll ask you to please keep this information between us, to refrain from having the magic council informed of this, your majesty." he requested.

A look of uncertainty passed Toma's face as he wondered what it was that was causing so much conflict. "Alright, this will be kept confidential unless you request otherwise," he reluctantly agreed.

"Thank you," Makarov said as he exhaled a sigh and readied himself to reveal one of the guild's biggest secrets to the King of Fiore...
