"Acnologia", said Natsu enraged. 

"Calm down Natsu", said Irene as Acnologia and Igneel used their breath attack.

The entire landscape was instantly destroyed as smoke filled the battlefield. 

Wendy coughed as she rises to her feet.

"All those layers of defense still didn't protect us from their breath attack huh?", said Wendy.

"If it weren't for those defenses, you and Natsu would be dead", said Irene.

"Where is Natsu?", asked Wendy as she looked around.

Acnologia and Igneel then took the skies as Aldoron and Viernes joined. 

"Their breath attack did no damage to them?", said Wendy in shock. 

"Of course it didn't, you have quite the defense dear dragonslayer", said an unknown voice.

"You!", said Wendy.

"Selene", said Irene.

"Had to be you who orchestrated this attack, how much do you know sister?", asked Selene.

"Everything, we've come to take back Ignia and defeat you", said Irene.

"The girl and the ghost are here to defeat me huh?", said Selene as her magic power caused the earth to shake. 

"She's strong", said Wendy.

"Get ready Wendy, the battle is about to begin", said Irene.

............

"Acnologia!", said Natsu enraged. 

Natsu then skyrocketed into the air as he heads straight for Acnologia.

~Fire Dragon King's - Demolition Fist - yelled Natsu as Igneel blocked his attack.

"Dad, what are you doing!", said Natsu as Igneel catches him.

"I asked him to come, the Dragon Gods aren't an enemy you can beat all by yourself you know", said Igneel.

"Even so, why do we need his help? We could have gotten Gajeel or Sting", said Natsu. 

"Don't focus on the Dragon Gods, we'll take care of them, we cannot defeat the dragon gods but we can slow them down, Selene is lending them her unlimited magic power and strength, help your friend take down the Moon Dragon God, once she is defeated, the Dragon Gods will fall", said Igneel. 

"What do you mean you can't defeat them? You're the Fire Dragon King and he's the King of the Dragons", said Natsu. 

"Acnologia and I aren't at full power, for every minute we're here in Elentir, we lose power, this is Selene's world, we're just guests, they have the hometown advantage, there's something strange about Selene's magic power, now stop distracting us and help Grandine's child take down Selene", Igneel commanded.

"Selene's magic power? Alright alright", said Natsu.

"Now, go, Natsu!", yelled Igneel as he threw Natsu and he soared through the sky like a meteor falling to the ground. 

....

"Wendy! Now", yelled Irene.

~Separation Enchantment~ yelled Wendy.

"I see, you're trying to separate my spirit and my body!", said Selene.

"Success", said Wendy as Selene's spirit and Irene disappeared.

"So while you fight my body, Irene will fight my spiritual form, not a bad plan", said Selene.

~Sky Dragons Roar~ yelled Wendy.

~Moon Dragons Gale~ yelled Selene as she blew away Wendy's wind.

"Your wind was stronger!", said Wendy in shock. 

"My magic power is way stronger than yours little girl", said Selene.

~Moon Dragons - Comet~ yelled Selene as a ray burnt Wendy.

"You surely didn't think this would be easy?", said Selene as she laughed. 

~Arms~ said Wendy as her magic power rose.

~Dragonslayer Secret ART- Shattering Light, Skill Drill~ yelled Wendy hitting Selene at point-blank range.

"Light", said Selene as Wendy's attack disappeared.

"No way, you ate my secret art!", said Wendy in shock.

"Anything that possesses light I can eat", said Selene. 

"That's impossible", said Wendy as Selene snapped her fingers.

Day suddenly became night as the moon shun brightly.

~Sky Dragon's Roar~ yelled Wendy.

~Moon Dragons Roar~ yelled Selene as a bright burning light hit Wendy.

Wendy fell to the ground in pain as she yelled.

"Her magic burns me", says Wendy as she struggled to get up.

"The light of the moon burns away magic power", said Selene as Igneel and Acnologia fell to the ground.

"My power is draining from my body", said Acnologia. 

"How are you doing this?", asked Wendy.

"The moon is the source of magic power, it was the first thing created in the universe, it was created by the Demon King, who was the first person to wield magic", said Selene.

"The primordial magic was darkness?", asked Wendy.

"Yes, the demon King used 10% of his magic power to create God Ankhseram, he bestowed her the magic of Light and creation, he then used 40% of his magic power to create the gods, his own children sealed him away to hell, once banished to hell he used 50% of his remaining magic power to create the sins, know this dragonslayer, the sins are way more powerful than the gods", said Selene as Wendy rose up. 

"You know the end-goal of the sins?", asked Wendy.

"Of course I do and I will help them achieve it, for when they achieve their goals, the demon king will rise again", said Selene.

"When he rises, he will destroy everything, Elentir will also be destroyed", said Wendy. 

"I signed a blood pact with Lucifer, Elentir will not be harmed for you see, once a blood pact is signed, it is impossible to break", says Selene.

"If you believe that then you're dumber than I thought", said Wendy as Selene raised her eyebrows. 

"You lost the minute you stepped into my world, your magic power is slowly sapping away", said Selene.

"We will defeat you", said Wendy.

~Arms, Vernier, Armor, Enchat~ yelled Wendy.

"Powering up yourself serves no purpose, you're already out of magic power", said Selene.

"I wasn't enchanting myself", said Wendy as the sky glowed.

~Fire Dragon's Kings-Demolition Fist~ yelled Natsu as a huge explosion as Selene yelled in pain.

"How did you manage to hit me, light is ineffective against me", said Selene burnt. 

"I heard everything, never underestimate a dragonslayers hearing, light is ineffective against you, the fire glows but the fire dragon kings flames are darkened", said Natsu and the earth rumbled. 

"How is your magic power is growing", said Selene in shock. 

The earth then split apart as lava seeped onto the ground. 

"The core of your planet is fire", said Natsu.

"That's hundred's upon hundred's of miles away, there's no possible way the core of Elentir would reach you", said Selene. 

"You've underestimated Wendy, the way she is now, I hate to admit it but she's stronger than me now.", said Natsu. 

"This little girl enchanted the entire planet and used Universe One to bring the core of the planet closer to the fire dragonslayer and he has the flames of the fire dragon king, who the hell are you two!", said Selene enraged.

"We are", said Natsu as he ate the fire at his feet.

"His fire is burning away Elentir's magic power!", said Selene in shock.

"We are Fairy Tail wizards", said Wendy as she ate the air.

"You've both entered dragon force!", said Selene.

Wendy then trapped Selene in a tornado as Natsu ignited it, becoming a fire tornado.

"You ready Wendy? Our magics are compatible", asked Natsu.

"Yes, let's do it", said Wendy. 

~Magic Power Fusion~ said Wendy and Natsu as he held hands.

"A unison raid huh?", said Selene as the winds blew violently. 

~INFERNO CYCLONE~ they said as the unison raid hit. 

 Selene then yelled Elentir caught fire.

"We did it Wendy", said Natsu. 

"Yeah", said Wendy as she smiled. 

....

"Wendy, can you hear me?", said Irene's voice.

"Irene-san", said Wendy.

"What did you do?", asked Irene.

"We defeated Selene", said Wendy as the flames that covered Elentir disappeared. 

"No you didn't whatever you just did, pissed her off, she's very angry", said Irene as a dragon roared loudly.

"No freaking way", said Wendy. 

"She turned into a dragon!", said Natsu.

"You gone and done it now", yelled Selene.

"She's preparing a roar attack", said Wendy. 

"Is she planning to wipe off the entire planet?!", yelled the Wood Dragon God Aldoron. 

"Selene, calm down", yelled Viernes as the sky glowed. 

"She's way beyond reason now", said Aldoron. 

"We are all out of magic power now", said Wendy as she fell to her knees as the light blinded her. 

Selene then roared.

"Wendy!", screamed Natsu.

"I'm sorry, Natsu-san", said Wendy in tears.

A bright glowing light then covered them as Selene roared.

"It's all up to you now, Irene-san", said Wendy.
