In the last chapter, Lucifer appeared and cast the ~Amaterasu: Formula 1000~ spell, the guildhall explodes, what happened to our heroes? 

~Third Person POV~

"Bye Bye, Earthland wizards", said Lucifer as he disappeared.

The dust settled as the battered and torn Fairy Tail flag falls to the ground, a single scream could be heard in the outskirts of Magnolia as Lucy rises.

"What just happened?", she said confused.

"Lucy!", said Erza and Juvia as she joined them. 

"What are we doing all the way out here? Weren't we just at the Fairy Tail guildhall?", asked Lucy.

"There was a bright red light, right before the guildhall exploded", said Laxus as he joined them.

"This familiar light", said Erza.

"Universe ONE", said Zeref as he joined them.

"Black Wizard!", said Gray as he appeared.

"I am not your enemy anymore Gray Fullbuster", said Zeref.

"Universe ONE huh? Wendy cast such a high-level spell!", said Lucy in shock. 

"What exactly is Universe ONE?", asked Juvia.

"It's a spell that Irene created, to move people from one place to another, that spell saved us but it felt different this time", said Zeref.

"What do you mean?", asked Erza.

"This is Universe ONE on a greater scale", said Zeref in shock. 

"Hello, can everyone hear me?", said Mavis.

"Warren's telepathy", said Juvia.

"First Master, what just happened?", asked Lucy.

"I have no idea", she says.

"I can tell you", said Laxus' voice.

"Laxus!", said Erza.

"Wendy was secretly working on a new spell, she upgraded Universe ONE", explained Laxus.

"She upgraded such an arcane spell!", said Zeref in shock. 

"She called this spell, Galaxy ONE", said Laxus as everyone's faces dropped.

"What exactly does this spell do?", asked Makarov.

"It moves people through space itself, the spell was imperfect but I'm guessing in the heat of the moment she got it right", said Laxus.

"No way, I can't believe this little girl could do something like that, Irene was right to put all he faith in Wendy", said Zeref.

"Does that mean Wendy moved herself to Elentir!", said Lucy in shock.

"It seems she took some people with her", said Sting's voice.

"Sting you're okay!", said Yukino's voice.

"It would seem everyone is fine but who did Wendy take with her?", asked Makarov. 

"Our enemy is the dragon gods, something tells me they won't be defeated so easily", said Jellal's voice.

"Her mission, defeat Selene, Aldoron, and Viernes and rescue Ignia", said Makarov.

"If Selene is defeated, Irene will take over her body", said Zeref.

"This fight is the beginning of our counterattack against the demons, she must win, if she fails then the destruction of the 7 realms is guaranteed", said Mavis.

"Let's put all our faith in Wendy then", said Levi's voice.

.........

Location: Elentir. 

"Seems our guests have arrived", said Selene as she rises from her throne.

"It would seem so", said Viernes. 

"Viernes and Aldoron, deal with them", said Selene.

"I don't like that you're commanding me around", said Viernes.

"I brought you to a safe place, didn't I? This is the least you can do", said Selene.

"Fine but just this once", said Viernes.

"What are you going to do?", asked Aldoron.

"I'm going to hunt down my sister, I have to kill her as soon as possible for if we fight, Elentir itself will be destroyed", said Selene.

"Your sister? You mean, there's someone whose power equals to yours?", asked Aldoron.

"No, don't be silly. No one equals to my power but this one's going to put up quite a fight for you see, we mustn't be too loud for we'd wake the sixth of the Five Dragon Gods", said Selene with her evil smirk.

"You're right, we must never allow him to wake, for if he does, it will be the end of us all", said Viernes. 

"Go both of you, entertain our guests", said Selene. 

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

"We're here", said Wendy out of breath.

"What did you do to my Universe ONE spell little dragonslayer?", asked Irene in her spirit form.

"I dabbled with it a bit, I was planning on using it to go to Edolas, to surprise my guildmates but now that I've learned that Elentir exists, I brought us here instead, I call this spell Galaxy ONE", said Wendy as Irene's eyes widen in shock.

"You really have surpassed me", said Irene as she smiled. 

"Wendy", said Natsu as he joined her.

"Natsu-san", said Wendy.

"What happened? The guild just exploded", said Natsu.

"I'll explain later, our enemy is on their way", said Wendy.

"Defeat the Dragon Gods right?", asked Natsu.

"You really do listen", said Irene. 

"I'm all fired up", said Natsu as fire radiated from his body. 

A strong gale blew as the sky suddenly blackened. 

"They're already here?", said Wendy in shock.

Two dragons flew ahead as they roar loudly as they prepare a breath attack. 

The entire sky then glowed with a blue and red light as they merged together and turned the sky magenta, the attack came from opposite sides of the sky as the dragons were covered in an explosion.

"Someone here! Who saved us", said Natsu as a chill went down his spine.

"Natsu-san", said Wendy as she looked at him as the two dragons fall to the ground. 

"Wendy! Who did you bring with us!", said Natsu as his eyes widened as the words came out of Wendy's mouth. 

His wings fluttered ahead as he came into view.

"Wendy, arm yourself and Natsu, he's going for a breath attack!", said Irene.

"Dragonslayer Defense UP, ARMOR", said Wendy as Natsu's gritted his teeth.

"Our trump cards have arrived, you were smart to have brought them", said Irene as Wendy covered herself and Natsu with 20 layers of defense. 

"No way", said Natsu enraged as his veins pop out.
