In a different realm
Serena (POV)
Mandalay and Igneel are in my domain conversing.
Mandalay- It's been seven years to the day since our children have been asleep.
Igneel- Not only our children but the entirety of the Fairy Tail guild on that island. The island itself has gone completely under the surface of the water ever since Acnologia attacked. That was quite some spell by Seth eh Serena?
Serena- It wasn't just his spell that made this happen. I sense this is part Mavis's doing due to the fact that the guild hasn't aged in the slightest and yet their injuries have slowly been healing with magic.
Mandalay- Well at least they're safe but, the world has moved on without them and the rest of the Fairy Tail guild has fallen into despair. I say it's time that we reintroduce the world to the rest of the Fairy Tail guild. Are we all in agreement on this?
The other dragons nod their heads in agreement.
Serena- Then it shall be done.
Serena *mind*- Seth, my sweet baby boy. It's time to wake up now. The world needs you. Wake up my dear precious son.

Back in Fiore, Tenrou Island rises from the depths of the sea by Master Mavis as a Fairy Tail ship approaches.

Dreamscape
Seth (POV)
Seth *mind*- It's been so long since I've been trapped in this darkness. Is this what death feels like? I haven't felt anything in so long. All I feel is cold. So so cold...................I want to live again.
Suddenly the void gives way to a bright golden light and Master Mavis stands before me.
Seth- Master Mavis, I'm so so sorry I failed you. Acnologia was too strong. He treated me like a rag doll. (Tears up) Everyone died because I wasn't strong enough to protect them.
Tears roll down my cheeks as Mavis approaches me. Much to my surprise, she hugs me. Well, as best as she could since she is short.
Mavis- You couldn't be more wrong even if you tried.
Seth- What do you mean?
Mavis- You saved everyone and this sacred land. You fought bravely against Grimoire Heart and deterred Acnologia. However, I did help out a bit. You see, I added my own barrier on top of your barrier at the last second and I sunk the island underwater. I put everyone into a deep sleep as soon as Acnologia's attack connected with the barriers.
Seth-..........Damn.
Mavis- Now I come before today to tell you that it's time to wake up. The world as you knew it before is gone. Everyone on this island has been asleep for seven years so that the ether nano could dissipate.
Seth- Seven years?!!!!!!!!!! What the fuck!!!!!!!!
Mavis- Yes I know. It was the only thing I could think of. Please don't be mad.
Seth- Im not mad. Just really surprised.
Mavis- That makes since and I'm glad you're not upset with me. Now dear Seth, it's time to wake up. The world needs Fairy Tail once more. The world needs..........you. I command thee to awaken!!
Real World
Seth (POV)
I open my eyes and shoot straight up in a sitting position.
???- Easy easy my boy.
Seth- M-Master?
My eyes adjust and when they come into focus, I see the everyone surrounding me with smiles on their faces.
Seth- ..........Hey guys. I'm back.
I eye Erza who's giving off the most gentle of smiles

She steps forward and crouches to my level. She then pulls me into an embrace filled with emotion.
Seth-.........I missed you too.
Erza-...........Come on, let's go home.

At the Fairy Tail guild hall

Romeo (POV)
Twilight Ogre, a guild basically full of bullies is about to trash the place because we didn't have money to pay them this month. I've had just about enough of their bullying and stand up to them.
Twilight Ogre Cronies

Romeo- Screw your master.
Macao- Watch it Romeo.
Romeo- You're not getting any money from us today.
Red shirt- I suggest you drop the attitude brat.
Romeo- You may be able to boss dad and the others around because they're scared of standing up to you but, (activated magic) If the won't, I will!! I'm not gonna let you Gus disgrace Fairy Tail's good name!!

Red shirt blows out my fire.
Red shirt- Hate to tell you kid but Fairy Tail's name has been disgraced. You can train all your life and there's still no way you could ever beat me!
He takes off his club and swings it at me. Suddenly, he gets hit from behind and goes through the wall behind me. A flash of ice, a swing of s sword, the burning of fire, and impact of a iron club and they all get taken out.
As the smoke clear I see them. The ones who vanished along with Tenrou Island seven years ago.

However, one of them is radiating that familiar magic that was held by a namesake of Fairy Tail.

It's none other than Seth Alighieri.
Seth- So you want to diss Fairy Tail Huh? Big mistake bitch.
Indigo: That's The end of this one. They didn't die after all. I'm so happy. However, everyone is older now except for them. Seth is literally supposed to be twenty seven at this point. Man this is strange. I guess they'll just have to figure things out. Well, hopefully you guys enjoyed it. Later indigo fam. Peace.
