6 years have past. 

Allen kept his true power a secret despite telling everyone what is his magic.

Allen learns that he can use his full power but can't control like it in the past so he trains in order to control it.

He doesn't needs a house because he have a palace in his own world that he can get to by dimensional gate.

Allen can have unlimited money pretty much because he can create gold and magical weapons.

Because of this he doesn't go on missions that much.

-Events

-Happy is born

-Meeting Gildarts

-Lisanna still went to Edolas

Allen tried to Lisanna to his personal world but instead got teleported to Edolas and couldn't get her back. Every time Allen tries he went to a different world. So Allen gave up on the idea. He told Elfman, Mira and the others that she is in another world but they thought they she went to the otherworld as in heaven.

Allen live his life peacefully except that he beings of other worlds on a regular basis. They are the demon gods of the fallen planets.

It's basically going to be episode 2 of Fairy Tail and Lucy enters the guild.

Natsu kicks the door open and decides to pointlessly fight. Allen stay away from these fights.

Allen [Same as usual. Ummm...I haven't recognize you are you new here.]

Lucy [Yes, I'm Lucy Heartfilia. I see that you are the only sane person here.]

Allen [Me sane? Ummm.. I guess so considering some of thse guys but you're get used to it. Pointless fights always tends to be the norm here.]

Lucy [I see. That's great.]

Mira [Hello, are you new here?]

Lucy [It's Mirajane! Shouldn't someone stop them.]

Allen [It will stop in a minute.]

Lucy [Ok.]

Mira gets hit.

Lucy [Mira, no.]

The chaos continues until the guild master comes. Lucy got her stamp from Mira and of course Macao was caught by a Vulcan. Allen volunteer to go get back Macao.

In the carriage.

Happy [Allen, you're never team up with anybody.]

Allen [I wanted to keep all the rewards for myself and I can get the job done quickly myself.]

Allen turn to Lucy.

Allen [You're a Celestial Wizard from those keys I see.]

Lucy [Ah, yes I am. And what kind of magic do you do.]

Allen [I use 5 unique types of magic. One of those types is able to summon just like your magic except I don't use keys or go the Celestial World.]

Lucy [Where are we going to.]

Allen [Mt. Haboke. Lucy you probably need a jacket. Mt. Haboke is blizzard mountain.]

Lucy [It is. Why you didn't tell me earlier?]

Allen [You never said it.]

Allen make a portal and gets a Jack for Lucy.

Allen [Take this.]

Lucy [Ah, thanks.]

Carriage guy [This is far as I can go.]

Natsu [We stop moving]

The team goes out into the mountain looking for Macao.

Lucy [It's still cold with this jacket on]

Allen [Well, it is a strong blizzard.]

Lucy [Oh, I know *summons her clock spirit*]

Lucy, Natsu and Allen chat for a bit before a vulcan jumps down onto them.

Allen [Natsu, that's a Vulcan. That might be Macao.]

However, the Vulcan already grabs Lucy. Natsu runs to get back Lucy while getting knock of the mountain. Allen arrives at the scene and does a charge weapon launch while Lucy turns her head away from the Vulcan.

Lucy [What you defeated him already?!]

Allen [I'm pretty strong.]

Natsu came back while Macao turn back to normal.

Natsu [Where is that monkey? Macao!]

Allen [That monkey was Macao. I should treat him. Regeneration]

Macao is heal back to normal.

Lucy [Wait what happen.]

Happy explains what Vulcan are and the team went back.
