This is another plot bunny that just won't leave my head after reading u/6347541/digemsmack 's Master Dragneel story, so if you are interested in making it, pls send me a pm or review. :)
XoXoX Fairy Master
More or less it's a what if story, where Natsu gets flung away from the others during the fight with Acnologia and isn't fast enough to get back to the group and as such is not in the Fairy Sphere when Acnologia shoots his breath attack, he'll get knocked unconcious by the tidal wave engulfing the spot where Tenroujima was.
XoXoX
He'll be picked up by Ultear and Meredy who will have gotten to and taken over the Grimore Heart airship by then, having talked to Gray about her abandonment Ultear will feel indebted to Fairy Tail, hence her saving Natsu, the rune knights will not have seen him, which is why they don't pick him up, Zeref will have evacuated the ship by the time Ultear and Meredy gets onboard, they will feel strange about seeing the corpses of people that they worked together with, even if they never liked them.
XoXoX
Natsu will be angry and cry because of what happened, this is where the pairing comes in, after reading Master Dragneel i became kinda partial to the Natsu/Ultear pairing, so when he is crying she will feel a sense of deja vu and see an image of herself superimposed on him and want to comfort him in the way that she herself never got when she learned about Gray and Lyon, this will be the start of their friendship that will later become an actual romance, Meredy will give a sad smile at the scene and think that even if she don't like Natsu, even in her mind, no one deserved to see all their friends die like that, she will feel respect for Natsu for being able to cry where most men would just hold it in and never release their feeling properly, she will also think that Ultear's own wounds to the heart is finally healing, even if only by a little bit.
XoXoX
Natsu will defend both the girls when they get back to Fairy Tail, the ship will be hidden far away, they will later reclaim it under the guild name, both Ultear and Meredy will join Fairy Tail and get a pardon from the council after they reveal all that they know about the Balam Alliance, as well as presenting the corpses of both Hades/Purehito and the other people that was on the ship when Zeref used the spell to kill Hades/Purehito, the info they give will be backed by Cobra(Erik) and Richard, who will later get out and be integrated into Quatro Cerberos and Lamia Scale respectively under surveillance, Cobra(Erik) will later join Fairy Tail on Natsu's request, he will hint at Kinana being at the guild, though Cobra(Erik) will not know who she is until he joins, then he will understand what Natsu was talking about, Richard will get in contact with his little brother later on and Wally will join Lamia Scale after the X791 Grand Magic Games, he will talk to Erza about how she meet his brother and he will apologize for Richards action, they will also talk about Sho and Milianna, the later who will join them shortly afterwards, Sho will not join a guild at any point in the story, but he will appear at both Erza and Jellal's wedding(end of story or in after story chapter(s) and the Tartaros arc, all of the former residencents of the Tower of Heaven will visit Simon's Grave, where Jellal will apologize to all of them for his actions back then, to which Angel and Midnight will call him a pansy.
XoXoX
Natsu's and Ultear's relationship will badly hidden, but no one in Fairy Tail will comment on it, Meredy will at one point tell Natsu she approves when she finds them in a restaurant a few month later, to which they will blush and smile, Ultear will tease Meredy that she needs to find a man of her own, to which Meredy will jokingly reply that it might be a woman, Natsu will snort in response and Ultear will be surprised at the answer, but she will nod in acknowledgment, Meredy will leave them be after that.
XoXoX
Fairy Tail will not participate in the Grand Magic Games of X784 citing the reason of needing to rebuild their guild, which will lead to Natsu's quick but brutal exam and subsequent promotion to S-Class, something he will feel bitter about until after his first child is born on the same day two years later, Natsu and Ultear will get married as a result of them finding out she is pregnant in year X786, he will still feel remorse for none of his old close friends being able to be there and see it since he will believe they are really dead until a week before Tenrou will resurface, he will be at the coast and feel a hint of their magic but will not know that it's them, he will just feel nostalgic, but once he gets the message from Warren Rocko about two days before they return about them being alive he will connect the dots and smile at the news finally able to let go of his resentments, but he will keep the news to himself as when the Tenrou group returns the guild has already left for Crocus seeing as the magic games begins soon and the two groups will not meet up until the second day of the magic games where it will be a four guild free for all with each guild having three people each, Erza, Gajeel and Natsu will be Fairy Tail's members.
XoXoX
Natsu will pick up Sting Eucliff and Rogue Cheney sometime in X784-X785 you decide when exactly, he will defend them from an angry mob that Lector by mistake made angry, Frosch will not be with them until late X785, Natsu will be helping them with a quest after they become Fairy Tail mages and Sting being the young teen that he is and the admiration he has for Natsu will make him ask Natsu to train him, which Rogue will want in on, but the quest is to get back an egg for a museum that was stolen by thief's, at the end of the quest Frosch will be born from the egg, the intendant of the museum asks Rogue if he wants to keep the Exceed and he will by answer by giving the newly born Exceed the name Frosch, Natsu will reminisce with a smile how similar the situation was to Happy's own birth back in X778, the experience will feel bitter-sweet to Natsu, but he will not show it, for fear of ruining the occasion.
XoXoX
Natsu and Ultear will name their first born, a little girl who will be born a week before date, Risa, after Lizanna, at first they can't choose a name and then Ultear start suggesting different names based off of people that they know, Mara after Macarov, Rona after Cana's last name of Alberona, Mina after combining Mira's and Lizanna's names and then Connell after Alzack's and Bisca's family name, they were gonna name them the childs godparents anyway after all the help that the two had been, given their experience after having a child of their own, but Natsu will feel that they don't fit, Natsu then suggests Ulianna after her mother Ul, but Ultear will reject it stating that she would not feel happy with her child bearing a name based after a woman that she had hated for so long, Natsu will then try Luciel after Lucy, but Ultear then suggests Risa stating that she knew of his feelings for the deceased girl, telling Natsu that he sometimes says her name in his sleep, which he will apologize for, but Ultear will just tell him off for trying to apologize for still feeling love for a girl that can no longer reciprocate, Ultear is happy that he is hers and don't feel any jealousy, even joking that she would certainly not mind sharing should the girl still have been around, since she in her own words could use the help keeping her insatiable husband satisfied, to which Natsu will be a little embarrassed, but will accept the name.
XoXoX
Alzack and Bisca will name Natsu and Ultear Asuka's godparents, Natsu will throughout X784-X786 train heavily as he feels that what he has is not enough to classify him as S-Class, as such he will learn that he doesn't just have two elements to his Dragonslayer style, Fire(primary) and Lightning(secondary, gained from Laxus), but he also has Ether after the event at the Tower of Heaven, he has just not noticed it, he can use it either alone or to empower one or more of his Magics, but he will also find and learn Fire Make, he will feel that he it reminds him if his old friend and rival Grey and will therefore learn it, he will find that he can also change his Dragonslayer enchantment from Lightning to Black Fire or later on Holy(after he trained Sting), he also learns generally known Magics such as Though Projection, Telekinesis and Minor Telepathy, he also learns both Law and Abyss Break in X789, it's unknown when exactly he learns the Heavenly Body Magic spells that he knows such as Grand Chariot and Altairis, but it's know by some that he learned it from Jellal Fernandes whom he has a secret alliance with from part way through year X786, though it was rocky in the beginning, after he learns the reason for the man's creation of Crime Sorcière he will forgive him and even make use of the old trick of Mystogun's to have meetings with him, this had the added benefit of making the rest of the guild believe that Mystogun was back, when in truth it is Jellal, Natsu will apologize for this to the guild once Erza notices who he is during the Grand Magic Games of X791.
XoXoX
The then Master of Fairy Tail, Fourth Generation Leader, Macao Conbolt, will comment at one point or another in X785 that Natsu has a familiar necklace, Natsu will tell him that he didn't know how he got it, but that it was Gray's, he woke up with it in his hand on the now Fairy Tail owned airship named Celestial Wolf after the Island that was no longer in existence, Natsu will by this point have grown his hair out and combed back the middle part of it, letting the side bangs hang loose, his attire will consist of 3/4 shorts, that has been mended with metal strips and bolts more then once, dark grey combat leather boots in the common style of sailors, no shirt, that shows the new placement of his Guild Mark, on the middle of his chest, below the necklace, he will wear a thick and large black coat that has a large hood, this coat will get more and more ragged as time goes on, by the time that the guild reunites on the second day of Grand Magic Games in Crocus in X791 it will be nicknamed the "Reaper's Cloak" because of how it looks, it will have the addition of a thick black fur lining at the collar, Natsu will also find a pair of Loke's old blue tinted sun-glasses in the guild storage sometime in X787, he will also start to smoke cigarettes when he turns 18 in X784, he will have grown to adult heights by the time X786 rolls around, he will drink, but he can't get drunk because of his magic.
XoXoX
Romeo Conbolt who works with Alzack and Bisca on quests as Team Concert, named after the fact that all three members have last names that starts with Con, the cert part was originally a mispelled word meaning something else, but the name stuck and the three decided to keep it, the boy will fight with Sting Eucliff for the so called "right" to teach Natsu's first born, given that the both admirers their fellow guild member greatly, they both want to teach the little one, Ultear later has to step in and tell them that they both can teach little Risa, but only if they get along, but also that it will be a few year before they would be able to since Risa was only a year old at the time, they both sheepishly agrees.
XoXoX
Ultear will get pregnant three times, first with a girl in X786 again in X790 with a boy and one last time in X791, but that birth will have complications that stop Ultear from having anymore children, the last child will be a boy as well.
XoXoX
Natsu will be after recommendations given by both Macao as Fourth Gen Master and Wakaba as then Sub-Guild Master named the Fifth Generation Guild Master of Fairy Tail in the beginning of year X786, he will continue to stand as guild master until Macarov returns in X791, he will resume that post in X793 after the Tartaros attack where Macarov tries to disband Fairy Tail and Natsu lectures Macarov on responsibility, not to others, but to oneself, Macarov stays a Fairy Tail mage but becomes a council member on Natsu's recommendation following the lecture, the two year add-on from canon is to allow Natsu's children to grow a little, he needs a reason to be really angry at the attack, what better way then his children being in danger, that and Ultear should not be pregnant during such an important time that will most likely feature her alot.
XoXoX
Natsu will be named a Wizard Saint in X788, by the time X791 has come around he is already considered the strongest outside the four gods of ishgar, though if he is stronger then Macarov is still to be seen, though it's know that he is pushing double S-Class from X789 and onwards.
XoXoX
Natsu will get to know his origin as an Etherius Demon during the Tartaros Arc from a lengthy talk with his Brother Zeref, Natsu, who will remaining calm, is in fact rather angry that Elfman was made to destroy the guild house at the time, but he knew that it was not Zeref that gave that order, it didn't fit his character, though Natsu notes during the conversation in his mind that Zeref seems to be the kind of person that is desperately searching for a meaning to his continued existence, Natsu will get to know later together with Macarov that Mavis and Zeref was infact in love, he will wonder if part of the reason for his Brothers unstable mind is infact Mavis death and thus the reason he wants to destroy Fiore.
XoXoX
Natsu will fight Marde Geer on his own, having gained the knowledge of his own past he kills his old subordinate, telling him in his final moments that E.N.D. thanks him and tells him to rest well after so many commendable years of awaited service and that he is not needed anymore, Marde Geer will notice that Natsu is infact his old master, his last though will be that his master looks far more happy then he ever had, Natsu will gain back his old powers from the book by destroying it, thanks to Igneel reviving him and the time magic that brought his body to the future he no longer needed to fear the books destruction, as he no longer was a spiritual entity, he later amused noticed that the book he had found that taught him his Fire Make style, was infact his own tome, he had just not know it at the time he found it.
XoXoX
His conflicting Demon and Dragon natures will be the reason for why he can never go back to being full Demon or become a true Dragon, Acnologia will not appear at the end of Tartaros arc, as such Natsu can keep his surrogate father alive, allowing him to connect Igneel as a kind of Guardian Spirit for his entire bloodline, sans Zeref for obvious reasons, but including Ultear.
XoXoX
All of the Tenrou group will be surprised at Natsu's change over the years, but will not know he is a guild master until after Chapati Lola askes Yajima if it's ok for a guild master to participate, to which Yajima will say that it is ok as long as there is another person in the guild that can stand as guild master while the person participate, that and they have to never enter more the two out of the five games, unless it's a year where there is more games, such as that year where there is seven games, then he could participate in three games, but any more and it would be too unfair an advantage in comparison to the other guilds.
XoXoX
Macarov will ask Natsu if he has switched guild later at night during the second day of the Grand Magic Games when everyone was drinking and partying, this of course gained everyone's attention to which Natsu just shows his Guild Mark while smoking, drinking and enjoying the company of his pregnant wife and guildmate's, this action of course triggers a gigantic surprise reaction of awe, horror and fear, Natsu of course will be annoyed at their reaction but will know that they had only know the old him, though the old Fairy Tail members will try to somehow make sense of the revelation, all the while lining up the old Natsu that they know with the responsibilities of a Guild Master, which of course only produces shudders and complaints that is rebuffed by the remaining old and all of the new members Fairy Tail that had been there and seen it all as Natsu grew up, while this is going on the loudest complaining ones being his old rivals Grey and Erza gets kicked in the shin, not doing much damage to either Erza or Grey but nonetheless gaining their attention, only to see Risa, wondering who she is, they will be told off that her "Papa" was an amazing Mage and Guild Master, this of course triggering another reaction that made Ultear come to her husbands defence telling Grey off and subsequently silencing everyone there, which made him finally notice just Who had been seated beside Natsu the entire night, which revealed that not just was someone he had though an enemy really now an ally, but also the wife of his rival And the mother of the child by his feet, bringing a final third Shrill reaction from the formerly missing members of Fairy Tail, this ending up with Macao and Natsu as the Fourth and Fifth leaders of Fairy Tail to explain more in detail what had happened while the Tenrou group was sleeping on the submerged island, much to the horror of Macarov and several others finding that Natsu was actually above Macarov in every rank sans seniority.
XoXoX
Sting and Rogue will still be called Twin-Dragons, but now of Fairy Tail and they will be the ones to fight in the first day magic games labyrinth, they are also the dual father godparents for Natsu's second child, the boy named Nagi, Nagi's godmother is Wendy Marvell, while Grey and Juvia is named such for the third and final child, this child will be named by Juvia, she will name it Juniper after her father, Ultear jokes that it was a rather feminine name, but that it fit somehow, Grey agrees having by this point much like Lyon come to see Ultear like a real sister and fully supports the woman's relationship with his old rival, now Guild Master(sorta).
XoXoX
Natsu will have a slightly hard time reconnecting to Happy, Ultear will be the one to explain to Happy why Natsu is so distant, that is when it will become apparent to the Tenrou group just how hard a time their guildmate's are having while trying to hide that they too is having a hard time reconnecting to their friends, given how many years they though them dead, that was not so hard to understand, the Tenrou group grew great respect for their old comrades for the effort.
XoXoX
After Natsu has left the tavern and Ultear has explained to Happy why Natsu has such a hard time reconnecting to his old partner Exceed and then pointed out that the others old members is having the same problem and Macarov has lectured them on the admirable fact that they mourned them, got over it and got stronger from it, showing that they didn't really mourn their death, but rather celebrated their lives, it is at this point that Sting tells Lector and Frosch to introduce themself to their fellow Exceed, this being the point that the three other Exceeds, Happy, Charle and Pantherlily notices that, indeed there is two other Exceeds there which is the happy end of the night.
XoXoX
Fairy Tail will be allied to four other guild by the time year X791 rolls around, Quatro Cerberos, Lamia Scale, Blue Pegasus and later in X787 Mermaid Heel, the reason for the alliance with both Quatro Cerberos and Mermaid Heel is the reemergence of some rather dangerous magical beasts such as a new generation of Dragons(they are still Drakes all the way to the end of the story), Cerberus beasts, Hydras(three-headed only), Sea-Serpents(they will be called Leviathans), various elemental birds and Shadow Tails(large dark horses with a lightning bolt like horn that uses black lightning)
XoXoX
Meredy will have only so much screen time, but try to add her where ever it feels right, i'd recommend to pair her with Doranbolt/Mest.
XoXoX
Ultear and Meredy will have already been working on the ability to open peoples Second Origin, as such Natsu will serve as the first trial for the script spell, they will afterwards determine that only S-Class or borderline S-Class Mages should be given the chance as the pain could be too much someone that is weaker then that level.
XoXoX
Rogue and Gajeel will later become sparing partners, Gajeel will of course be paired with Levy romantically, Rogue will not yet have found someone by the stories end.
XoXoX
Charle will have learned how to become human-shaped by the time X792 rolls around, this occurring when Wendy visits Mermaid Heel, Yukino Agria will have joined Fairy Tail back in X788, as such the hotel incident on the first day will not occur, Yukino will have become a singer on top of being a mage of Fairy Tail, a popular one at that, together with Kinana, Enno, Chico. C. Hammitt as well as a few other girls that joined when they were still growing as a band, they were the ones who created Fairy Tail's "Battle Theme Song" Chasing Real Dreams(named and made after the 15th anime opening) that they sing in the opening of all Grand Magic Games that Fairy Tail participates in, aside from X787 and backwards, Wendy still becomes a singer together with Shelia Blendy, they will be know as the "Sky Sisters", they will have a bit of a rivalry with Yukino's Fairy Children group, though Fairy Children don't even know of it, so it's quite a one-sided rivalry.
XoXoX
The Eclipse Gate incident will still occur, it's too useful of an event to not use inorder to kill of a few unwanted characters, such as the mayority of Sabertooth, since Sting and Rogue is not in it, the catalyst for it's change can't occur, that and i always though that Jiemma was used far too much for such a lowbie character, plus his death was Not satisfying, just relieving that he was finally gone, a more annoying character you will have to search for, plus i, and probably you want Sting and Minerva to be paired, that would be a good way to redeem her, plus i always though that her personality changes and battlefield side alignments never made sense.
XoXoX
Raven Tail will not participate in the X791 tournament, they will be killed off during the 7 years before, how is up to you.
XoXoX
Twilight Ogre will get the shit beaten out of them by Natsu, Ultear, Meredy and the rest of Fairy Tail that is around in late X784, Fairy Tail will have had 112 members before the Tenroujima incident, that number will lower to 86, but will quickly rise back up to 91 before the Twilight Ogre incident, by the time that X791 rolls around they will be 560 members with 23 S-Class members and 2 SS-Class, this being Natsu and Ultear, Sting, Rogue and Cobra(Erik) are all among the S-Class members, there is several other, but most is not named, after the 21 people stuck asleep on Tenroujima returned they numbered at 581 with 4 additional S-Class members returning, this being Macarov, Erza, Mirajanne and Gildart, Loke was not stuck there as he was desummoned when Lucy was made to sleep by Fairy Sphere, therefore had no way back into the human world, as for Doranbolt/Mest, he teleported off the island by orders of the then Rune-Knight Commander Lahar Pars, though he will not be considered a member until Macarov returns his memories after the Tartaros arc.
XoXoX
Natsu will be one of the two Guild Sub-Guild Master after he became S-Class until he is promoted to Guild Master, he will be taunted by dark guild people that he is following a "weakling" for Guild Master, which will not end well for said dumb people.
XoXoX
Ultear will study the healing arts from Porlyusica, the pink-haired woman will also be the one to help deliver Ultear's and Natsu's children, all the while commenting over the reckless behavior of "Children" much to Natsu's frustration and Ultear's eternal amusement.
XoXoX
The war with Zeref and his kingdom will not occur as Natsu's acceptance of his Demon heritage and Mavis regaining her body will have satisfied him into not invading, he still highly dislike Fiore, but he stealthily names his "Older" Brother's children possible heirs to his throne, Zeref will also have found a way to touch Mavis, without killing her body, again, but they will find out fast enough that they cannot have children hence Natsu's children being heirs, only Natsu, Mavis and Zeref knows both of these facts, also, given what we have seen in the manga and the anime, there is also the so called "fact" that Natsu is the "Younger" Brother between him and Zeref, this only being that way because Zeref has Lived more years, but Natsu is still the one born first.
XoXoX
Zeref takes great enjoyment in calling Natsu "Etherius" rather then his more used name, much to Natsu's chagrin.
XoXoX
Jellal will be pardoned of his sins for his work in the Tartaros arc where he helps in the location of and subsequent guarding of several Magic Council members during the Face incident, Cobra(Erik) and the other Tower of Heaven members will also be pardoned at the same time to show the world that the council has changed it's ways.
XoXoX
Gajeel, Levy and Lily will still become Rune-Knights, but only on a per-call basis, Erza is also called upon to help train the Rune-Knights from time to time.
XoXoX
Risa will inherit her father's Fire Make, that she later developed into the Blaze Make magic-style, Nagi will go for his mothers Time-Arc style much to Sting and Romeo's dismay, given that this is the second time that they have not been able to influence one of Natsu's children, though he will still respect his teachers greatly, even if he doesn't use their styles, Juniper will not become a mage at all, much preferring to become a writer and note down his siblings and his extended family(Fairy Tail)'s adventures, he shares his godmothers Juvia Fullbuster and her closest friend Lucy Heartfilia's love of romance and everything that comes with it, though despite not being a mage by profession he still learned both the Ice-Demon Slayer magic style from his godfather Gray Fullbuster and the Great Sea magic style from his godmother Juvia Fullbuster.
XoXoX
Erza Scarlett later Fernandes was named Sixth Generation Guild Master of the Fairy Tail guild by the Fifth Generation Guild Master Natsu Dragneel in the year X805, she had two children by then, both of whom inherited their parents unique hair colors, though it can be noted that the older child, her Daughter has a rather apparent crush on the romance loving child of the previous Guild Master.
XoXoX

XoXoX
Fairy Tail was the first guild given the ability to freely hunt dark guild in the year X786, in commendment for their work again the Balam Alliance.
XoXoX
The Fairy Alliance, consisting of the guilds, Fairy Tail, Quatro Cerberos, Lamia Scale, Blue Pegasus and Mermaid Heel, held for over a hundred years, the longest registered alliance in Fiore's history, this was broken by the Mage War of year X897, as a result of enemy nations not wanting the allied guild be so much of a thorn in their side, despite the loose of this powerful alliance, Fiore still came out on top in the war and flourished for it.
XoXoX
The slaying of the final Dragon happened in the year X832 and was done by the combined effort of 8 different Dragonslayers, their names were never recorded, but many have spectulated.
