A/N: Hello Everyone! Looks like I'm trying my hand with my first ever crossover, mainly because I'm interested in opening up the possibilities of such ones between these two franchises and wish for everyone else to enjoy what I see going for it. Along with that, I've actually had some of this written down a few years ago on an old flash drive I found and after reviewing what I wrote, I knew it needed a major revision which made me decide to split the chapters into parts. This is my first attempt at a crossover and if you would like to inform me about some things I may not know about the Gate universe, please don't hesitate to tell me (I'd really appreciate it). As a final note, spoiler warning for those who only watch the anime for Fairy Tail; I'm using a number of points of its ending although I'm going to take the liberty of changing a few things where I see fit. Kind of obvious since the main cast are doing this rather than what they had planned to do. A bit of a disclaimer I assume, but with that out of the way please enjoy the story!

Battle of Crocus Pt. I

A tale as extravagant as Fairy Tail's adventures through the years has become near common knowledge for the millions living in Fiore, which was much more apparent in the it's capital of Crocus. The young queen, Hisui, herself could still see the guild's banner being flown within the city even after two weeks since their victory at the x795 Grand Magic Games as she looked out from one of the windows of the castle's grand dining hall. Turning on her heal, she began overlooking the large dining hall table that seated her advisors, confidants and a few political guests she was entertaining. Queen Hisui had a fond smile on her face as her father ate away happily at his meal from his own personal seat next to her own at the head of the table, an act that used to be a rarity when he was still the crowned king of Fiore not two years ago. If she had to be honest, Hisui had her fears about inheriting the throne after her father had abdicated his position, but she did her best in the first few months she went into power although there were some problems.

As much as she wished not to notice it, the then newly appointed queen of Fiore was fully aware of a few political enemies that tried to undermine her power with a simplistic cover up argument of her being too young and unprepared to truly rule. Personal informants loyal to the crown kept tabs on these upstarts and their actual intentions, but her moment to truly shine came when she helped establish a peace treaty between her country and the Alvarez Empire. The treaty itself gave Fiore a powerful ally due in part to the queen's expert diplomatic skills, which had also allowed the country to obtain some of the technological advancements the Alvarez Empire had been privy to. Fiore benefitted through the treaty and began to prosper soon after, gaining praise from both the people and influential individuals; however, it was a useful thing to also be friends with Fairy Tail with mutual support and understanding between each other.

Such were her thoughts in those few occasions she allowed herself to think back into the early stages of her rule, but they were soon moved aside as her appointed second-in-command of the Fiorean army, Arcadios, stood puzzled looking out a window near the main entrance of the hall. The head knight had been invited to join the get together by his queen, but decided to keep guard and minded his own business as these other important figures enjoyed their lunch, but his attention was later entrapped by plumes of smoke on the horizon from within the city and wondered if a fire had started in a building. His thoughts and the guests' conversation were interrupted when a breathless royal knight barged into the dining hall with a sense of urgency written across his face.

"Your highness the Capital's under attack!" The nameless knight exclaimed as Arcadios immediately made his way over towards his majesty, low murmurs beginning to flare up from those at the table to the severity of the attack and worry for personal safety. Even if they were seated inside one of the most secured buildings within Crocus.

"Who would dare attack the capital?" The former king, Toma Fiore, questioned as the knight tried to catch his breath, steadying himself with his spear as there was no doubt he came from one of the greater entrances of the castle nearer to ground level.

"We are unsure who it is, reports from engaging knights indicates that it is a battalion of monster-like creatures with an unidentified army following behind them!" A cold sweat dropped down Toma's brow as the sounds of screams began to resonate inside the room and he balled his fists in anger. Aside from Irene's unbelievable power when she attacked, not once has he ever faced an attack on this scale in his time as king. "Some of our men have mention seeing an unknown structure near the south that could be where the enemy is coming from."

"Send all available knights to defend and evacuate the citizens immediately, whoever this enemy is can destroy the city but I will not allow them to attack my people!" Hisui commanded as Arcadios nodded his head in understanding, full knowing that it was time to take charge of the counter attack.

"You heard her highness; send the knights out and activate the rune barrier to protect the palace. We'll use this as an evacuation point with the Garou Knights safeguarding the area and send my Cherry Blossom Knight captains to act as the main vanguard for the counter attack!" Arcadios ordered as the royal knight saluted before running off to communicate the orders.

"As for myself, I will stay at your sides until this attack has been resolved." The armored man said as he bowed towards the royal family.

"Your loyalty is very much appreciated Arcadios, but until we fully know who are enemy is, we must still garner more reinforcements against the enemy. Our own knights are capable, but I still worry for those who will be overrun when evacuating the citizens." Queen Hisui replied as her father nodded in agreement, her minor combat knowledge pointing out the necessity of having a supporting force that can help the army from being stretched too thin.

"My daughter is correct Arcadios, we need to contact all the guilds and have them send any capable mage available for Crocus' defense." Toma suggested as mages will be needed to repel the enemy's magical capabilities, whatever they may be. "Contact Fairy Tail first, they are the country's strongest guild after all and with them at our side we won't be facing defeat anytime soon." The short man said as grin spread across his face as everyone in the room knew that with Fairy Tail, surrender isn't in their vocabulary.

"Please hurry, the lives of our people depend on it" Queen Hisui added as her sentiment for her people was contagious and all those in the room could almost feel her worry for the citizens in the midst of all the chaos below.

"Right away your highness." The armored man replied to his queen as he marched off to find a nearby communications lacrima.

In Magnolia, the sun shone brightly over the city with its iconic guild of Fairy Tail as rowdy as ever on this fine day, though they had to be reined it just a little for the sake of a few young ones among them. The guild went about their victory at the Games with a celebration that lasted throughout the day of their return well into the night, but of course that was two weeks ago and now it was back to business as usual. The eighth guild master Makarov sat in his wheelchair on the main floor, his children surrounding him; however, he had a sense of worry wash over him as he solemnly took a sip from his mug. The feeling was almost tangible to Makarov and he could tell Fairy Tail's involvement would be ever so apparent in it, but what that was remained to be seen.

"Master, there's an urgent call from the palace." Mirajane informed as he quickly asked the elder Strauss to wheel him into the back rooms with an available communications lacrima to receive the call.

Luckily enough, a meeting room that had been kept clean and upkept without much use was free and housed a lacrima on top of the main table in the center of the room, even though Mira slide it closer to the side so Makarov could see. The aging master allowed his magic to flow into the lacrima and was met with the serious expression of the royal family's holy head knight; Arcadios. His feeling was right on the Jewel if the royal family was calling upon him and his guild, but the old man was very aware there was no way he'd turn away from helping those in need.

"I apologize for the sudden call Master Makarov, but we need your guild's support immediately, it's an emergency." The old master knew it to be a serious problem by the tone of the armored man's voice, though he sighed to himself as he thought about who he would send first.

"What's the problem Arcadios?" Makarov asked as he needed some more information before sending away his children into danger, not that his brats wouldn't be able to handle themselves but it was natural parental worry the aging master had for all of them that made him cautious.

"The capital's under attack by an unknown enemy, we are trying to evacuate the civilians towards the palace and the arena, but request further support for our counter attack. Do not worry, we'll be contacting all the available guilds to lend us their support as well." The dark skinned man replied as Makarov nodded his head in understanding.

"I'll see what I can do, but for the meantime, could you quite possibly put her Majesty on? I have a request to ask of her." The old master wondered if this would be useful and as the holy knight went off to get the Queen, Makarov had asked Mira if she wouldn't mind fetching Erza, her team, Wendy, Gajeel and Laxus. The white haired woman nodded her head, seeing where the old master was suggesting and immediately went off to get the called upon mages.

It wasn't long before the seven mages, including Levy and her daughter Gale, had walked into the the Master's office with the exceeds not far behind, unaware of what exactly he needed them for. As a given, an argument worthy suggestion began to spring up between the ice mage and dragon slayers to what the reason may be before Erza had silenced them all. What they hadn't expected was for the Queen of Fiore to be on the other end of the lacrima sitting atop of the desk the Master was nearby of and made themselves presentable in front of her. Makarov face palmed as Gray had walked in shirtless and remained that way in front of her highness until Wendy handed him his shirt and coat. As the ice mage began to redress himself, Makarov cleared his voice to regain everyone's attention on him so that he could send in the support team towards the capital.

"Listen to me you brats, I know this may be very short notice but Crocus is under attack at this very moment and I'm sending you lot in to help protect the innocent and assist the counter attack." Makarov claimed as a grin spread across Natsu's face as he was prepared for action, a similar reaction that was shared amongst most of them.

"Here we go again." Lucy muttered to herself as Wendy chuckled a little towards her claim, but they couldn't deny that there was a form of excitement building within them.

"All of you need to be there immediately and conventional travel would take too long, not to mention that Mest can only transport a certain number of you at a time before becoming exhausted. That is why I'm asking the Queen if she could help open a Celestial Spirit gate to get you there in one go." Makarov said as he hypothesized that if Lucy opened one of her gates on this side, the Queen could open another on her side.

"Although it has not been done before, I could have one of my contracted spirits guide them from the spirit realm here." Hisui replied as Makarov took it as a go ahead, hopefully it would work given the circumstance.

"That'll have to do. Erza, Natsu, Gajeel and Laxus will support the vanguard, Gray and Lucy will assist the secondary force at the center and Wendy will provide support and help heal the wounded, understood?" The old master said as he tried forming a quick battle plan before they departed, and he was answered with an agreeing cheer that put a smile on his face.

"They could go through the Spirit World, as for me I'm going there in my own way." Laxus said before stepping out onto the adjacent double doors leading outside and disappearing in a strike of lighting, which wasn't very surprising to everyone since they knew that it was his own personal way of traveling when he went solo.

With that distraction, a very worried Levy had decided to get some words in with Gajeel as she had no idea that this was what was happening and on a day that they were supposed to spend as a family. The bluenette never liked it when the guild was placed into such predicaments with lives on the line and now that she shares one with the man she loves, it only seemed logical that it bothered her that he was being sent out to some war zone. The solid script mage knew what she was getting into when she married him, since he was a dragon slayer and as mages of Fairy Tail, but her worries stemmed mainly around the impact it would have on Gale.

"Are you really going to go, just like that?" Levy asked as she pulled Gajeel off to the side while she held Gale tightly in arms, worried that they wouldn't see him again if he's going into something far more dangerous than what they've been told.

"Gihi, it takes a lot more than some nobodies to take me down. Don't worry so much, I'll come back home for dinner." Gajeel whispered to his fretting wife as he picked up his daughter into his arms. "Wish daddy luck out there and remember to be a brave girl while I'm gone, okay?" The iron dragon slayer was met with giggles from his two year old in response before Makarov began talking once again.

"Now remember brats; protect the civilians, push back the enemy and make sure to come back here in one piece, understand!?" Makarov exclaimed as he was met with even more cheers of the small attack force that would be sent in first.

"Your Highness if you will, please have a spirit at the ready." The aging master asked as he noticed Lucy summoning Virgo to assist them on their travel.

"No problem, she will be waiting for them in the Spirit World as we speak." Queen Hisui replied as the mages behind them disappeared in a shimmer of golden light, already on their way towards the battlefront.

"Thank you your Highness, we'll keep in contact and have a new group of well prepared mages to assist you shortly." Makarov spoke up as the Queen bowed her head in thanks before Arcadios did as well and turned off the lacrima.

"I have a strange feeling, like the sense of a dark time fast approaching and this unknown enemy is pushing my worries forwards even more." Mira said as she was positive that an army would've been easily spotted thanks to the use of the more advanced detection systems in the capital.

"I must agree with you there Mira, these old bones get the feeling too and they haven't lied to me yet." Makarov replied as he went off to prepare the rest of his brats for another battle to come, he just hoped it didn't escalate into another full blown war that would endanger their lives.

In the Celestial Plane, the Fairy Tail's first responding group and the Exceeds were rushing through the realm with a maid spirit leading them towards her gate where her master was waiting for them. Due to the urgency of the situation there wasn't enough time for a dress change so Wendy had created makeshift air bubbles for everyone to breath with. Although this type of spell was one of her latest ones she has become proficient in, it was working perfectly well though the other spirits remained on standby in case they were to fail and provide the necessary assistance needed.

Amongst them all, Natsu was the most excited for a chance to fight and Gajeel was no different, however the same could not be said for Erza as she still questioned how an enemy of such great number was able to infiltrate the capital. She had gotten word that Alvarez had help implement a new detection system as with the pass war being a prime example of Fiore's inadequacy of detecting enemy forces through their original means. The redhead's personal informant hadn't gotten any word on his end of enemy movements on the capital and Erza could only assume that these people were trying their hardest to remain undetected until the very day of their attack. The requip mage's thoughts were left to linger until Natsu cheered from the sheer excitement of combat, even if he had no idea what kind of enemy was waiting for them once they arrived.

"I'm getting fired up now! I can't wait to show these guys what happens when you mess with us!" Natsu exclaimed as the opened gate was getting closer, although Gray didn't share the same sentiment.

"So long as you remember what we're supposed to do hot head. Protecting the people and pushing back the enemy are our main objectives." The ice mage couldn't agree with the dragon slayer's attitude as they were lucky in the past with their major battles, but he wouldn't start to test how far their luck would stretch. Not to mention the fact that Fairy Tail's involvement in serious engagements was becoming much more apparent to him, even if they had a relatively peaceful period.

"I know that ice bastard! I'm just saying, it's been too long since my last fight!" Natsu replied although the others knew very well that the dragon slayer was receiving a few complaints from the destruction he had done to a forest from his last battle not five days ago.

"Alright you two stay focused, this is our stop." Erza spoke up this time as the celestial gate lay open before them and the maid spirit ushered them through with a bow.

The first thing they were met with was the relieved faces from Queen Hisui and Arcadios as the Fairy Tailers began to pour out of the Queen's celestial gate and into the the throne room. One thing they all did was take in a new breath of fresh air, they knew Wendy out did herself with the usage of the air bubbles although the negative to it was that they were only breathing in stale air for quite a while. Though the air wasn't as fresh as they would've thought as the next thing they were hit with was the smell of smoke. They all turned to look out a window and noticed the numerous plumes of smoke coming from the southern part of the city.

"Thank goodness you all made it safely." Queen Hisui said as she rushed towards them while Arcadios awaited the return of his Holy Knight captains after summoning them sometime before Fairy Tail's arrival.

"Travelling through the Celestial World may be convenient with two Celestial mages in different areas, but I doubt I want to do that again without the proper clothes." Lucy replied tiredly as the danger itself wasn't very well recognized while they ran through their spirits' world, but she trusted the spirits to make sure their lives wouldn't be in any mortal danger.

"No kidding, but how long has it been since you called for us?" Gray asked as he remembered that time works differently in both their worlds.

"It's been about two hours since Fairy Tail's been called and your friend, Laxus, has already been dispatched to the southern part of the city. Since the time displacement of the Celestial Spirit world was factored in with your arrival, we've done what we've can on our end and moved to the throne room to continue any further courses of action." Arcadios said as the footsteps of armored boots could be heard approaching the throne room. "In any case, Laxus has already managed to hold ground at his current location all on his own, but it seems that the enemy has spread out to the eastern and western areas of Crocus. Our knights are staving them off as best they can, but it won't be long until they're overrun, especially near the arena."

"That is troublesome indeed, but what about the other guilds? Have any of them arrived yet?" Erza questioned as she looked out onto the city, watching as the plumes of smoke seemed to be growing in number in a few areas and listening to the sounds of explosions and screams resonate from within the city that only served to churn her stomach.

"Most of them are already on their way as we speak, but on short notice some of the trains had delays and Blue Pegasus' Christina required to be re-armed for combat." The holy knight replied as he was saluted by the captains who had finally arrived.

"Looks like we don't have support for a while, but Fairy Tail's more than enough to get the job done." Natsu said as he cracked his fist with a challenging grin on his face.

"There's no doubt about that, so I pray that our victory comes swiftly and the tides of this battle drastically change." Arcadios then pointed towards the four men who stood waiting at the doorway of the throne room. "These men will help lead you towards designated battlefronts that require immediate assistance."

The men varied in appearance, two of them looked to be seasoned veterans if the scars on their faces were of any indication and the sharp stare they were giving towards the mages made them gather an understanding that they've fought against their kind and obviously came out victorious. One had graying hair along with his beard, but he didn't give off a harsh vibe as one would expect but his armor did show markings of his battles over the years and he held himself like a man who had walked through the expanses of hell itself.

The other was a taller man with not as much gray although it was still visible amongst his auburn tresses, his lower left cheek marred by old burns and a scar going down his right eye that was covered by an eyepatch. He held himself similar like the previous man, however he seemed much more calculative and bits of his armor were missing from sight. Although it was very obvious that the dragon slayers and Gray were fully aware of the stench of blood that not only came off from their boots and armor, but heavily from their weapons.

The other two were younger captains that looked to be no older than Laki, but even they didn't seem to be pushovers either. One was a sandy blonde young man who wore a very familiar armor type with a very recognizable crest, which was the reason he had been eyeing at Erza for a while already although she wasn't particularly focusing on him. A distinctive feature aside from his armor and hair was that there were remnants of dried blood smeared across his chestplate and greaves, which brought a worrisome feeling in Lucy and Wendy of how serious things had gotten out there.

The other young man was slightly shorter with light green hair, his armor more in line with the newly standard captain's armor which paraded a number of dents and scratch marks running across his chestplate, gauntlets and pauldrons. What was interesting about him was that alongside the blade he kept in a sheath on his back, he had two magic pistols on each of his sides in easily accessible holsters.

"This is Captain Jose Laurel, his platoon is overseeing the protection of the arena evacuation point, but they're being bombarded with waves of enemies and his men are growing exhausted with each one." Arcadios told the Fairies as the the auburn haired veteran stepped forward when his name was called.

"We've suffered casualties with what they keep throwing at us, but luckily my men are the toughest they could be and we haven't lost one civilian yet. Still, if nothing is done then the enemy will surely break through my men and the arena will become nothing short of a massacre." Laurel said as his gruff voiced easily matched his person, but the Fairies could tell that even he understood when the best interests for his men's survival was needed to be looked into before it was too late.

"Don't worry Captain Laurel, we'll be sending one of our best with you." Erza said as she looked over her band of mages and turned her gaze towards the iron dragon slayer. "Gajeel, I'm pulling you out from the vanguard so that you can go assist him at the arena."

"Fine, so long as I still get to bust some heads." The long haired man knew better than to question the Titania about being pulled from the front lines, but if enemies were still attacking then he was fine with it.

"Wendy you go and support him, I'm sure the palace has healers here to help the wounded, but it's not a sure thing there would be many at the arena." The young teen nodded her head in understanding before waving good bye to everyone and following after the captain, Gajeel and Lily with Carla following closely after her.

"With that, the evacuation points are secured until the remaining guilds' reinforcements arrive." Arcadios said as he then went back to facing the remaining captains, now pointing to the remaining veteran and the sandy blonde haired man. "The older man is Captain William Iris and the young man next to him is Captain Mori Peony, they are leading the main vanguard in the eastern and southwestern parts of the city."

"Given the current situation, we both were stationed towards the south until the lightning mage arrived. From there the enemy began to divide itself and went into three separate directions; continuing their advance from the south and straight towards the palace, east towards the arena and west in an attempt to flank the slayer and get to the palace that way." Captain Iris explained the situation and it made sense, tactically wise, to keep the slayer occupied with more troops while they went around him in a near pincer maneuver.

"Hmm, I suppose this is where Natsu and I must head towards. What of the west?" Erza could devise where exactly they were to look into, Natsu would head for the southwest while she can help deal with the east and ease the troop advance towards the arena although that left the west without support.

"We are holding well enough at the moment, the Garou Knights have supported us well through most of the fight once the palace had been well secured, but the enemy once again diverged and my men went after them once they ran further into the city." The fourth captain spoke up this time as he relayed the information he knew before heading back to the palace. "I'm Captain Tatsumi Gladiolus and I apologize for speaking out of line Sir Arcadios, but it is imperative that I return to the front lines and assist my men."

"If you believe that any help isn't necessary than very well captain, but what of the reinforcement platoon's captain? I requested for the both of you to return here." Arcadios had heard of the situation towards the west and sent help since the enemy forces were heading straight for Laxus in two directions.

"I'm sorry sir, but I never received or heard of any reinforcements up to this point. It's solely been myself and my men since our deployment to counter the enemy and it is that way as the Garou Knights have rerouted themselves to protect the palace." Captain Gladiolus replied as the sound of more metal boots rushing down the hall became louder until a wounded soldier came into view, holding onto his bloodied side while he attempted to salute to his superiors.

"S-Second Lieutenant H-Hanes reporting..." The young soldier said as the green haired captain rushed to his side before he collapsed. "Representing C-Captain Aster, we require assistance as soon as possible. Hostile forces...avoided the l-lightning mage and are headed for the palace, our platoon intercepted their advance but are being outnumbered..." That was all he managed to say before he succumbed to his wounds, thankfully Captain Peony, with what little healing magic he knew, acted as fast as he could and healed a portion of the wounds so he wasn't in mortal danger.

"That's what must have happened to my reinforcements." Gladiolus remarked as he carefully laid the young man down, calling for medics to arrive in the throne room yet he was worried for what might become of his men. "Even if I head out now, I'm unsure if my men and I will be able to make it towards their rescue."

"Don't worry about it, if they past Laxus then they're headed to strengthen their people battling our intercepting forces and that's where me and Lucy are going." Gray said with a confident smirk on his face as Lucy gave him a reassuring look. "We're both more than enough to rescue the outnumbered platoon and beat back the enemy."

"If you weren't members of Fairy Tail, I'd call you insane but that's not the case now is it?" Arcadios said as he gave a hearty smile at how far their enthusiasm goes. " Before you go, I must inform you that we've received reports that a temple like structure is the main cause for the continuous flow of hostile forces. Do what you can to stop this if you can, as for now you all have your orders so I'll leave the rest to all of you and with that, there is now no way we will let Crocus fall."

"Good, we know where we must go so let's head out people!" Erza exclaimed as she received a collective 'Aye' from everyone and the remaining Fairy Tailers and royal knights began to head out towards their designated posts.

After what the soldiers have seen and what the Fairy Tail mages have gathered thus far, it is nothing short of war within the capital of Fiore. Their enemy has no chance against their resolve of steel and the driving force of what it means if they failed to do everything in their power to make sure the innocent stay out of harm's way. Though caught by surprise, the defenders of Fiore now stand set and ready to drive the enemy into full retreat and back from wherever they came from.
