A/N: Hiya! This is a Golden SunXNaruto crossover. Let's hope this turns out well! :D

On some beginning notes, for this story it took about 1 ½ - 2 years to complete the quest in Golden Sun. Then there was an additional 2-3 years of reconstruction for Vale. The reconstruction is almost complete for Vale when the story begins. Our GS heroes are roughly 4 years older depending on their birthdays, which I haven't decided.

As per pairings, I'm doing Valeshipping and Sandshipping/Lighthouseshipping, whichever term you are more familiar with (If you go to Leoshi's "Fellowship of the Sand" forum, you'd know the first. If you haven't, go check it out. We welcome new people to the forum. :D). I may do more... *is indecisive*.

On Akatsuki notes, I really don't know about events too far in the Shippuden arc. I know of some things I've read about on here, but other things I don't, so please go easy on me and sorry if I give unintentional spoilers if there are others like me on here, or haven't finished the games, for that matter. Some things I might have messed with already, but I'll probably try to skate the line between canon and AU for both. In other words, you'll see some canon and some not depending on how it helps the story. xD Current Akatsuki members include: Pein, Konan, Itachi (is not dead), Kisame, Deidara (not dead either), Zetsu, Tobi, and one new member that you'll learn today. ^_^ If you see something wrong with Akastuki's or any other characterizations, please let me know. I haven't written Golden Sun in a while, and not being up-to-date on the Shippuden arc leaves me without as much knowledge of the Akatsuki member personalities. I'm just praying I don't botch this. xD And Kakuzu, Hidan, and Asuma are dead. Jiraiya's still alive though.

Complete Summary: The Akatsuki have failed in capturing the bijuus. After being scattered for a while in which their threat was forgotten, they have banded back together, and this time they have a new member, who's told them a legend of Guardian Summon, Guardian, and Summon spirits with the same power-giving abilities as the bijuus. The adept heroes and the enemies of Akatsuki will have to join forces if they wish to keep this new power from falling into the Akatsuki's hands, or this time Akatsuki may gather a complete set....

Disclaimers: I do not own Golden Sun. That belongs to Camelot. I do not own Naruto. That belongs to Masashi Kishimoto.

Prologue

It has been almost three years since the formation of the Golden Sun. With new power filling the land, it has ceased destroying itself; slowly, signs are appearing of Gaia Falls repairing. There hasn't been too much of an effect upon the non-adept peoples with the new abundant psynergy source as of yet, but it has been theorized that adepts will soon begin appearing again in greater strength as the generations prosper in this new era, and the power that was lost among the peoples returns to their hands. It will be then that the nations will once again by tested by the avarice that arrives with power; but, for now, our heroes are not worried.

Since their quest was completed, the reconstruction of Vale began. Once it was well underway and partially completed, the journey home began for others. Ivan headed back to Kalay after rescuing Master Hammet from Dodonpa's clutches, and he makes frequent visits to Contigo to visit his newly-found sister, Master Hama. He is growing stronger under her tutelage. Unable to return to Lemuria until King Hydros can win over the Senate to allow it, Piers began a semi-nomadic life, sailing the seas and journeying to visit between Contigo, Vale, and Imil, to which Mia had returned to run the sanctum and fulfill the duties of her clan, one of which was guarding the lighthouse. Even though it was already lit, she could still see to it that was well kept, she said, and it would be good to learn more about the history of the lighthouses. Piers began studying the Mercury Lighthouse and its history with her, hoping to learn something in relation to his homeland and if there was a connection between Imil and Lemuria. While visiting Mia, he also began learning more about healing techniques from her. The two became close friends.

As for our Valean heroes, they have continued the reconstruction of Vale and begun settling down. Garet began learning how to rule as Mayor, being his grandfather's chosen heir. Sheba stayed in Vale to be with Felix; and, the two have been engaged for a little over three months after dating for about a year. Isaac and Jenna became engaged shortly after the reconstruction began, and have been married for about a year and a half. Their first is on its way. Isaac is a very happy father and Felix is a very excited uncle, though both are (now and still, respectively) extremely overprotective with Jenna at times. Jenna is amazed she managed to marry and now live within married life at all.

All are at peace, happily rebuilding their previously broken lives. But, like any cliché prologue to a tale told by a narrator- even I, the Wise One, who sent Isaac and Garet on their initial quest- must announce that the peace they were enjoying after their long struggle was about to come to an abrupt end. A very abrupt end.

I never foresaw this. It was never meant to be this way. The tunnel was not meant to reopen, just like the Golden Sun was never meant to rise again and shine its light upon this land. Perhaps fate has intervened yet again…? I know not. I am not fate, nor do I make fate's decisions. But I do know of what is holding the sword against their throats for the trouble they shall newly face, pushing ever so slowly harder.

It is the Summons. The Summons that were sealed away within the elemental stars, the Summon Spirits of Weyerd, the guardians of this land like the Tailed Beast Summon Spirits of the other land, before those became other than what they were destined to be. Those ceased being Summon Spirits, left their tablets, and became an embodiment of chaos and destruction, the perfect prey for power for predators of ill intentions. But at least those are out of the wrong hands now, and these have a chance at salvation. These still have a chance not to fall as those did.

For the enemies of the land that the Tailed Beasts were meant to guard are coming, and they have a traitor of this world among them to lead the way in their infiltration. Unless they are warned, they may fall beneath the sword's revengeful strike. There is nothing that can be done to keep them out now, short of sealing the tunnel, which I cannot do. The balance of this world was already upset, and now that it is finally rebalancing, it wouldn't do well with another imbalance in the newly balanced equilibrium so soon. Moreover, when our heroes lit the final elemental beacon, they accepted the responsibility to take any and all possible consequences for their action. They will accept this consequence as well and overcome it, if they wish to protect their newly "saved" world.

But I can still warn them. They never knew about the summons sealed within the elemental stars they bore, like many other things that was never told of. They may not listen, but I will have played my part.

I'll have to hurry. The enemy is drawing near. This world cannot fall beneath their strike.

I am the final guardian, and when I appointed the elemental stars to them, thus I appointed them as well. They must take up their swords again and prepare themselves for battle. If they wish to save their newly reborn world, they must fight to protect it. They must fight with all of their strength- and with the other world's warriors if they must. There is no other option if they wish to save their world.

Let's hope this tale ends with the peace of the previous closing chapter of their story.

I may already be too late…

Chapter 1

Vale

A shadowy figure, faintly illuminated by the dim light from the full moon, conscientiously stuck to the shadows as he surveyed a small lantern-lit house by the river his cliff face overlooked. It was a cool night, and though there was a faint breeze that might carry his scent, he was sure there was no one that would have the skill to detect it. It was a useless precaution, he decided, as he felt the cool breeze caress his forehead and cool his beaded brow from beneath his straw hat that put his face in even further darkness. After all, it was an overcast night, even with a full moon; it wasn't like anyone could see him.

But he wasn't one to take unnecessary risks when others could it for him. Alas, he had no one to do it for him; thus, he would continue to ensure all his plans went according to his liking, but never be in a position where it was apparent of what he was doing. Fate seemed to have a knack for placing him in positions where that was possible, though he had more cunning people to contend himself with this time. He would have to watch his words and actions more warily.

Especially now, he thought to himself, as the night's chilling breath returned to rustle his black cloak. He vaguely noted that it was as black as the night sky, yet the red clouds that adorned it, while adding an aesthetic appreciation to it, did nothing in resemblance of the dusky heavens. Unless you were aiming for an image of the last day of the world and chaos. With the organization he was apart of, he could consider filing that notion of possibility away for later thought.

Finally, there was a movement from within the house he was patiently observing from his perch. The leaves whispered imperceptibly as he adjusted his footing. While the ninja sandals were extremely more comfortable and flexible, he preferred the sturdy durability of his boots, even if they were heavier- for a normal pair at least. His were specially made for being light and sturdy, as well as keeping his feet more secure. He hated how his feet slid in the sandals. They also kept his toes warm, an added plus which would've been denied to him on nights like this had he continued sandal use. He was never happier than when he returned to boots; he must be the only Akatsuki member that stubbornly wore boots.

And he was monologue-ing again. Sure, it was great for running through his plans, but one of these days it was going to make him completely lose his focus. Focus cost him his previous goal. This time, he would not fail. Akatsuki would gain the Guardian Summons and the remaining Summons, and he would have the omnipotent power he desired.

He returned his attention to the window, watching the occupants intently and careful not to let emotions cloud his focus or judgment.

A young man of about 21 was talking to a young lady of about the same age with reddish-brown hair. The man had messy dirty-blonde hair, and was dressed in a loose, light-colored shirt and dark pants. He had an expression of joy on his face as he spoke to the young lady in the nightdress; he'd had that expression often, a mix of joy and anticipation. Unfortunately, he could never get close enough to hear what exactly they were saying. The wind never favored him in carrying their voices within his elongated hearing range, but this time it did. It was only two names, but that was all he needed, for his heightened senses and previously mingling around the town could take care of the rest of what he needed to know, and the remaining proof he needed for his mission.

He felt the tendrils of the night wind tickle the shell of his ear as it whispered the names he sought:

"Jenna… Isaac…"

With a satisfied smirk, he leapt from the branches of his hiding place and disappeared in a quick burst of pulsing blue light. Leaving as silently as he had come, no one was the wiser of his watching eyes from the shadows of their peaceful village.

Cave northwest of Vale, in the mountains near Mt. Aleph

It was dark and dank in the roomy cave, but the only one who noticed was the one living person that stood facing the 7 shimmering light figures all wearing matching cloaks.

"The mission was a success," he reported to glowing shape in the center. "The bearer of Iris is indeed in Vale, and she's guarded with the one chosen by Dullahan." His voice was only slightly muffled from beneath the straw hat that enclosed his face in shadow.

"It appears the legend is true," Leader mused from his center position, his eyes even more unnaturally bright in his hologram.

Deidara added, "Now that that Guardian Summons' existence has been proven, all that is necessary now is a plan of action, hm."

"How do you plan to proceed, Leader?" Leader's partner asked, voicing her question from his right-hand side.

Leader was silent for a moment, debating the knowledge they had gathered with what could be done. Finally, he stated, "The way the Summons of this world interact with their carriers make for capturing them more difficult, as you never know if one particular summon has chosen a carrier or simply made a pact with that person, unless you stumble upon the carrier that can admit to either. Collecting them will be made easier since there's no pattern we have to follow in collecting them like the bijuus; we may collect one or we may collect them all. There's no way of knowing how many there are, either. Even the one who brought the legend to us didn't know, and he knew all that there was to be had on that subject from the resources pertaining to that on this world."

He was silent for a moment, and then he continued, "However, we do know that the most likely place to begin would be the original carriers of the Elemental Stars. When the Stars were removed from Sol Sanctum and the djinn released, the Summons were awakened as well. The only ones who can use the djinn are adepts, but anyone could acquire a pact with a Summon if the Summon thought they were worthy of it. In the end, they choose a carrier, and all pacts are cut off once the Summon is sealed within their chosen host. The first people they could evaluate were the original carriers of the Elemental Stars, the ones that journeyed to light the Elemental Beacons. Our informant has a pact with Haures, the shadow beast, and therefore does not have a Summon. He has said that a Summon and Summon pact cannot theoretically coexist. Consequently, we have no worries of searching for one we already have. And unless we ourselves can obtain pacts with any of the Summons, he'll be our only way of telling who is carrying a Summon and who simply has a pact. Only those that carry Summons or have pacts with them can identify others of their kind."

He paused in his explanation to ensure all his members were on the same page before he continued. Questions or misunderstands would slow their work down; he didn't want any time wasted. Since no questions left anyone's mouths to break the silence when he paused, he took a breath before continuing, "Of the fourteen travelers we are searching for, two died at the Venus Lighthouse, and therefore not in this consideration. Two more died in Mars Lighthouse, and therefore will not be discussed either. From those ten that lived to return triumphant from the quest, one was an old man, a scholar of no adept lineage or talent. He would most likely not have a Summon; it would laughable if he did. That leaves the eight remaining adepts, of which five reside in Vale. Three are men; two are women. Our informant has assured us that of those residing in Vale, fortune has shone upon us in that 2 of them have Summons we seek, from the 4 Guardian Summons. The other two are their Guardians."

A voice piped up from the end of the line of holograms, halting Leader's explanation. "Why are both called Guardians? It's confusing," the masked member interrupted, his voice complaining childishly.

Leader only gave him a look of, Do I look like I know or care what they are called?, effectively silencing the only member to voice a question. If only he would have someone ask intelligent questions….

A figure to Leader's left with the appearance of a shark spoke up. He was fingering the large, wrapped sword on his back. "So, we're after those two?" His voice was eager, and his small, beady eyes shined with anticipation of a fight.

Finally, my wish was granted, Leader thought. "The 4 Guardian Summons are the strongest Summons to exist and are made of pure alchemy power and psynergy, a pure concentration of elements," he stated. "Though they aren't made simply from the one they're named for, there is a Guardian Summon for water, wind, fire, and light. The Light Summon is the strongest Guardian Summon, as it contains the pure essence of the Golden Sun. On a side note, they can think for themselves, however, so they're also known as Summon Spirits, and appear to have genders, strangely enough. The Light Summon is the Guardian Summon Iris. Her carrier is a Fire Adept named Jenna, and her Guardian is a man known as Isaac, an Earth Adept. They both reside in Vale with the carrier of Catastrophe and her Guardian, Sentinel. Their respective carriers are a woman known as Sheba, a Wind Adept, and her protector is named Felix, an Earth Adept. Our informant was only able to pick these two out from the 5. The last is not supposed to have either a pact or Summon."

"So, we get to go fight them, right?" the shark-like member that been excitedly fingering his sword persisted. This time, he had grabbed the handle of his sword and was holding it front of him, as though by having his weapon ready he could wish a fight to appear in front of him to indulge on.

"We have no idea of their skill level compared to ours, Kisame. I do not want to base our entire estimation of their power based upon our one informant. However, I also do not want to let this opportunity pass us by," Leader replied. "We'll proceed with caution."

Kisame smiled, his obvious pleasure at the upcoming battle evident on his face.

"We'll send a reconnaissance group to test out the Guardians' strengths compared to the Guardian Summons' strengths. As their title implies, you'll most likely have to go through the Guardian before you can fight the Guardian Summon carrier. The working of the Summon Spirits appears rather recondite, but that doesn't mean we can't take what we do know and adjust accordingly to what we learn. Capture them if you can, but that won't be the main goal of this mission. I don't want any casualties since we don't entirely know what we're going up against, or if we should have fear of casualties at all. As I said, capture if the opportunity presents itself, but it won't be the central focus."

Leader paused, letting the mission sink in before presenting the question that he was already sure of the answer: "Any volunteers?"

Like clockwork, Kisame announced, "I volunteer myself and Itachi for this mission."

The member who had made the report laughed quietly to himself, though it didn't go unnoticed. As both of the members turned their gazes towards him, he said smoothly, "I was just wondering if this is Itachi's way of redeeming himself for his inability to capture the Kyuubi."

Newly-healed sharingan eyes burned him with the fiery intensity of his glare as his partner shot back, "I don't remember you helping us capture the Bijuus, medic."

This time the previously silent member openly laughed. "I didn't recall being an initiated member when that was being done," he said, before sliding in, "and I didn't think your ability to recall was that impaired, Kisame. Perhaps the medic should take a look at your status of health?"

Kisame's eyes narrowed at him while he issued a low growl in his throat. This guy always irritated him!

"However," the corporeal member continued, "there was some information by our informants that the carrier of Flora and her guardian Kirin are just outside the borders of Rain Country. I know that they aren't Guardian Summons, but they are Summons just the same. I would like to help in my duty," he threw out for Kisame's benefit. Kisame just continued to glare at him, not interrupting as he continued, "with Zetsu's assistance if he's up to it, being as we're temporary partners."

Leader looked at Zetsu, who gave an affirmative nod for both his halves. Debating on the request, he turned back to the tangible member standing in front of him, and was about to speak when the blonde ex-Stone member said,

"Aren't they that Kyuubi brat and his partner Haruno Sakura, hm? When did they get Summons, anyway?"

"When they unfortunately bumped into our informant shortly after his arrival," Leader intoned with indifferent patience. "Flora chose Haruno as her host and then Kirin chose the ex-jinchuuriki so as to be Flora's guardian, though their carriers haven't realized it yet."

"It's just ironic, really, hm. But so artistic and fitting."

Leader sighed, praying that he wouldn't launch into another speech about art. Thankfully, having only one artist had reduced the art arguments and speeches, though they unfortunately hadn't eliminated them. As his prayer was apparently answered, he once again returned to the task at hand.

"Kisame, you and Itachi will go to Vale and test the Guardian Summons Iris and Catastrophe and their Guardians Dullahan and Sentinel. Remember, this is strongly reconnaissance. Although capture is not required, if the opportunity arises take advantage of it. Don't waste this window of opportunity, but don't underestimate them either that the reconnaissance is undermined or casualties result."

Affirmative nods came from the respective members. Placated, Kisame was once again a lighthouse of ecstasy, his face shining with light of excitement for the upcoming battle he was hoping for.

As silence filled the cave, it appeared that the meeting was over. However, turning to face their plant-like member, Leader surprisingly announced, "Zetsu, you and our newest member will go to the border of Rain Country with the same mission for Flora and Kirin. The same instructions and precautions that I told Kisame and Itachi apply to you as well. Reconnaissance first and foremost, but since these aren't as strong as Guardian Summons, you'll have a greater possibility of capturing them if that window opens. As I told them, don't waste but don't fail in the original goal." Turning to face the physical member yet speaking to all, he intoned indifferently, "Is that satisfactory?"

Nods circled the rooms as all gave their affirmative agreement.

"Meeting adjourned then. Report back to the base in Cloud when your missions are completed, successful or not."

With that, Leader's hologram flickered and disappeared, followed shortly by his partner's. One by one, the others disappeared too, though not before Kisame sent a final glare towards the corporeal member, who only smirked back. When Zetsu was the last who remained, his white side said he would meet him at the old Rain base before they took off on their mission. Hearing an assent, Zetsu then disappeared.

Finally, it was dark inside the cave again, and silence reigned in the rocky dank. Still smirking to himself, the remaining person murmured, "Satisfactory, indeed," as he raised the hand with the Akatsuki ring, once Hidan's but now his, to grip the edge of his hat. He gave a firm tug, and then it gave way to reveal long, sea-green hair with similar-colored eyes to match. The ring choice was appropriate, he thought, since immortality was what he had once sought and almost obtained, had it not been for the blasted Wise One that had stood in the way of his goal, sealing the remainder of the power in Isaac when it was rightfully his.

He would have his revenge. Of this, Alex was certain.

A/N: No, I am not planning MiaXPiers, at least as of yet. You might see some hints of it, but as to a pairing, most likely not. As I said: 'close friends'. Most likely they'll stay close friends, mostly the type of those that share an intellectual interest and have a close bond.

Alex and Mia are siblings in this story. Camelot never says exactly how she's related to him, other than a member of her clan, but Unclever Title's review for jedigrl2001's story "Through the Other Eyes II: Bloodlines" had this interesting point/idea (I don't know which) that Alex was really her brother. I don't know if Camelot has specifically said that, but I thought it would be something interesting to try, at the very least. So, they're siblings here. (I wasn't trying to copy if think I am, and I couldn't talk to Unclever Title, since they were anonymous when they left the review. I just thought it was an really interesting idea to try.) Either way, Alex's betrayal hit her hard. She might find an empathetic kinship with Sasuke when she hears about him/ his story, but obviously there won't be any MiaXSasuke. Come on- a 21 year-old girl dating a 15 year-old boy? Get real. xD

What do you think of this so far? Good? Bad? Encouragement/reviews will help this continue. :3 Thanks for reading, and please review and tell me what you think! Thanks again!
