A/N This fic will be a supernatural type version of Canarrow and is inspired by the "Lois and Clark" episode in which H.G. Wells revealed that Clark and Lois's souls were bound together. Also, Olicity never happened.

Sara's eyes fluttered open as she started taking in her surroundings. A bright expanse of pure light surrounded her and permeated every corner as far as her eyes could see, and nothing else. As she tried to figure out where the heck she was and how she got there, she noticed a person standing next to her, and upon inspection, realized it was Oliver himself, looking as confused as she was and also wondering how he ended up here.

The last thing each of them remembered was that Sara was in the middle of chasing a lead on Vandal Savage with the rest of the Legends while Oliver and his team were busy trying to infiltrate a HIVE base respectively. All of a sudden, they both had started to feel dizzy and collapsed while their respective teammates cried out in alarm, that moment being the last thing they remembered. And now here they were, standing in an unknown location surrounded by nothing but light.

"Ollie?", Sara asked tentatively, turning her attention to him. She was beyond happy to see him again, especially after seeing his broken version in 2,046, but wondering why he was here.

"Sara?", Oliver asked her in return, also overjoyed to see her but unsure as to what had just happened to them. Before either of them could say anything further, they were approached by a mysterious and elegant but very elderly looking woman wearing a white robe and whose aura exuded limitless power.

"Greetings Sara Drake Lance and Oliver Jonas Queen. Welcome to Olympus, realm of the gods."

"Who are you?!", Oliver demanded roughly while positioning his body in a fighting stance and standing protectively in front of Sara who on her part leveled a glare at the woman. Neither of them knew who this woman was but would defend themselves if necessary.

"Fear not young ones, I mean you no harm. As for who I am, I am known as Clotho, or The Beginner. My two sisters are known as Lachesis, or The Middle, and Atropos, or The End. The mortals of the Earth such as yourselves are more familiar with our well known name, which is The Fates."

Oliver and Sara were very much surprised regarding the woman's identity but were not overly skeptical. Sara had seen a lot of crazy things in life apart from time travel, so the idea of The Fates really existing wasn't too farfetched. Oliver on his part had already experienced many incredible things which could not be explained by science, mysticism in particular. And after his adventure in the underworld to retrieve Sara's soul, he now knew that the afterlife and Hell really existed. Therefore, it was very much possible for The Fates and the legendary beings of Olympus to actually exist. The question they now had was this: If this woman before them was one of The Fates, what did she want with them?

Reading their minds, Clotho explained herself. "The reason why I've summoned the two of you here is because my sisters along with myself have decided the time has come for you both to be made aware of something very important to your lives, and in particular your relationship, both in the present, the past, and the future."

Oliver and Sara's eyebrows raised in curiosity at Clotho's words, perplexed as to what she was talking about. As far as they were aware, there was nothing really important about themselves. All they knew themselves to be was good friends who had an on and off relationship in the past before breaking it off completely and moving on with their lives. Though unknown to each other, they still harbored feelings for each other, feelings which had been buried but still existed. What could possibly be so significant about them that would attract the attention of The Fates?

"What do you mean?", Sara asked the being before her, trying to understand what this was all about. Oliver was also trying to understand what Clotho said about them but couldn't come up with anything and really wanted to know what she was talking about.

"What I mean is that the two of you are soul mates, and not just in the figurative sense", Clotho answered them. "Each of you is literally one half of a single living soul, and being a part of the same soul, it was predestined that you would always be drawn to each other, unite, fall in love, live a parallel life mirroring each other's lives, die, and then be revived and go on to take altered paths in this life such as when you Oliver went from The Arrow to the Green Arrow and when you Sara went from The Canary to the White Canary. And finally, when your times came to die, your shared soul will be transferred to the next couple who's destiny it is to carry that particular soul. You Sara are the female half of that soul while you Oliver are the male half of it, and that also makes the two of you each other's mirror selves."

Hearing this bombshell that Clotho just revealed to them caused Oliver and Sara's minds to go into a tailspin. Never in a million years had they expected to learn something like this. Literal soulmates who actually shared the same soul and that their romance was always meant to be? This was really some shocking information to say the least and would take awhile for them to process it.

"I know it's hard to believe", Clotho said to them, understanding what they were thinking. "But if you really think about it, my words make perfect sense. You see, you both started off as immature, selfish youths before spending years away from your home until you became trained vigilantes, were forced to join dangerous organizations during your third year away just to survive, started off as killers who fought in the dark before becoming heroes who now fight in the light, died in the exact same fashion in that you both were stabbed in the abdomen and fell off a high ledge before being revived, your paths towards becoming vigilantes was indirectly caused by the same man, Malcolm Merlyn, who also was the cause of your deaths, you both are ex members of the League Of Assassins and were harassed and threatened by them for refusing their demands, and finally, you shared involvement with the young woman Nyssa, even though her union with you Oliver was forced."

"You mean to tell us that we literally share the same soul?", Sara asked in wonderment, taking all of this in as she began to see her relationship with Oliver in a new and different light. At first, the idea that she and Oliver were soulmates united by a single soul was met with mild disbelief on both their parts after they got over the shock of it, but now after hearing Clotho mention all of those significant aspects of their lives, both Sara and Oliver began to see how it could be possible, not to mention the fact that revisiting their lives with fresh eyes caused them to realize how similar they were to the point of eeriness.

"That's correct young one", Clotho answered her. "And I have more to tell you both. The reason I mentioned that your soul will be passed on to the next couple destined to carry it is because your soul has resided within other couples in the past for centuries, and the very first couple who carried it were Robin Hood and Maid Marian. Not only were they were the first carriers of the shared soul, it originated within them when they were born. You see, all the couples who carried the shared soul were reincarnations of Robin Hood and Maid Marian respectively and now you Oliver are the current reincarnation of Robin Hood while you Sara are the current reincarnation of Maid Marian."

At this point, Sara and Oliver were standing there with openmouthed expressions. First, it turns out they're literal soul mates, then it seems their soul resided within couples in the past and will in the future after they're well and truly gone, and if all of that information wasn't stunning enough, they not only had the soul of Maid Marian and Robin Hood within them but were also their latest reincarnations.

"I must admit, but my being reincarnated from a medieval archer who fought the corruption of the rich in order to help the poor isn't really crazy considering what I do at night", Oliver said to Sara with a bemused expression. "And if we're supposed to be reincarnated soulmates and I'm the archer of our pairing, then it's only logical that you be the lovely but strong maiden who falls for me."

"That I can go with Ollie", replied Sara with a chuckle, but then she thought of something in particular that Clotho said which caused her to frown. "What did Clotho mean about you and Nyssa having a forced union?", she asked him.

"Last year, Ra's wanted me to become his heir but I refused," Oliver answered her. "He then turned our city against me and after threatening Thea's life, I finally agreed to his offer and joined him. However, I used that opportunity to infiltrate the League so that I could bring them down from the inside. Anyway, as part of my ascension to Ra's, I was required to marry Nyssa, and neither of us had any choice in the matter. I had to keep my cover and Nyssa had no option but to obey her father. We were married in a League ceremony though I assure you that it's not binding anywhere else except within the League, at least as far as I'm aware."

Hearing that Ra's had forced her two exes to marry was quite a shock to say the least, though not shocking as what she and Oliver had already learned from Clothos so far. Now she understood how she and Oliver shared a connection to Nyssa. She had been her lover, and now Oliver was forced to be her husband. Okay then. That would be a matter she and Oliver would have to deal with after she returned from her mission with the other Legends.

"I have more to tell you both, and it's the ultimate reason regarding why I summoned you", Clotho continued. "As I've revealed, the two of you share the same soul and should you ever rekindle your relationship and completely join yourselves together as one, then each half of your souls will be reunited which is how it should be. However, there are dark forces who conspire to destroy your love and will stop at nothing to accomplish this. These forces started their plans when the two of you were Robin Hood and Marian and acted through Robin's arch enemy, Prince John. He came after those versions of yourselves numerous times and tried to separate you with many nefarious schemes. He finally succeeded in doing so when he killed Marian with poison and went on to have a female assassin disguised as a nurse assassinate Robin when he was ill. As the years passed then turned into centuries, Prince John continued to wage war with your past selves and always succeeded in killing you both and will attempt again to do so to your present selves. In fact, he has already tried twice and is currently planning for the third attempt."

"Wait a minute, Prince John is still alive and exists in this time?", Sara asked incredulously. "How is that even possible?"

"It's possible because Prince John is an immortal, having been blessed with it by the dark forces seeking to destroy you and Oliver", Clotho replied. "They first approached him when the two of you were Robin Hood and Maid Marian and offered him unlimited power and immortality if he killed you and continued to do so in each of your reincarnations. He of course accepted like any evil tyrant willing to extend his life in order to continuously expand his dark influence. The only ones who can kill him are the two of you and only if you do it together and with your souls reunited as one."

Oliver and Sara took deep breaths upon hearing this while Oliver on his part used his hand to rub his forehead in order to soothe his weary mind. As if there weren't enough complications in their lives, combined with the knowledge that they're reincarnated soulmates added to that, now it seemed there was a new enemy from hundreds of years ago out to get them. Cisco's words suddenly entered their minds, words which seemed appropriate for the moment at hand and were as follows: "Since when did our lives become an 'Indiana Jones' movie?". Suddenly a thought entered both of their minds. If Prince John was still alive and out there, who was he and how was he aware of them in this life.

"Do you know who Prince John is in our time period and how he knows to target us in particular?", Oliver asked the Fate standing before him.

"He is currently disguised as a former businessman turned head of the terrorist organization HIVE and is the man responsible for the attempts on your life which I mentioned. You know him as Malcolm Merlyn."

"WHAT?!", both Oliver and Sara yelled with shocked expressions written on their faces.

"It's true I'm afraid. The first time he tried to kill you was when he sabotaged the Gambit. While he was out to kill your father Oliver, you and Sara were the primary targets. When that failed and he became aware of the fact that you both were still alive, he began to put a new plan in place which he then followed through on. He used something very dark to bewitch his daughter, your sister, into killing Sara. That in turn forced a confrontation between you and Ra's which lead to your death at Ra's hand, eliminating two birds with one stone as you humans like to say," Clotho explained to them. "He of course failed again since I and my sisters were unwilling to let either of die and let evil prevail. Your loved ones did their best to revive you but we also stepped in to insure your souls were returned to your bodies. And now Prince John, or Malcolm as you know him, is currently preparing to personally battle you both and kill you with his own hands and will continue trying until he's successful in this life."

It took a long while for Oliver and Sara to process this revelation concerning Malcolm. Everything that they were learning was beginning to cause their heads to hurt. They knew however that they needed to get themselves together and decide how they were going to proceed with this newfound information. What Clotho revealed did cause Oliver to realize something that he wished he'd considered before. Why would Malcolm coerce him into dueling one of the most dangerous men in existence and someone he barely had a chance against? He now could see the truth and it was that Malcolm had never wanted him to kill Ra's but instead wanted Ra's to kill him after Malcolm already killed Sara. Having this new understanding of what happened and why caused Oliver's blood to boil with rage.

"My goodness, our lives sound so much like Carter and Kendra with this whole reincarnated soulmates idea and an enemy continually killing us throughout time", Sara said with wonder.

"You're right, your situation does mirror that of Kufu and Shayera", Clotho said in response. "But unlike them, you and Oliver's souls are one, making your bond with him stronger and deeper than the bond Kufu and Shayera share."

Oliver and Sara nodded at this, indicating that they understood.

"But back to the matter at hand. As I said before, the only way for the two of you stop him is to allow your souls to be reunited", Clotho continued. "And in order for that to happen, each of you must look inside yourselves and decide if you still have feelings for one another. It's those feelings that from which therein lies the bond between you, the bond which when restored, will allow me to complete the process which will enable you to share the same soul. That will allow your minds to be fused as one and will allow your thoughts, feelings, memories, desires, and emotions to flow between yourselves. Each of you will of course have the ability to withhold certain things from each other if you so choose. Your essences will also be intermingled between the two of you, and your hearts will literally beat as one. Having said all of that, I ask you Oliver Jonas Queen and Sara Drake Lance, do you still love and desire one another? Are you willing to reunite your souls as one and defeat your most dangerous and shared enemy once and for all?"

Oliver and Sara turned and looked adoringly into each others eyes, all the love, desire, and passion between them rushing back to the forefront of their minds, and Oliver was the first to voice his answer.

"Yes, I still love Sara and have never stopped loving her. I should've never let her walk away from me and should've fught for us. I can now see that she's truly the one for me and no one else. My heart beats for her and the fact that we share the same soul is a dream come true and one of the greatest blessings I could ever receive. In fact, based on everything you've revealed to us and the knowledge that our love has been predestined, I wish to ask Sara here and now if she will do the honor of becoming my wife and completing our union", he finished while kneeling down as he spoke those last words.

Hearing the words of the man she still loved caused tears of joy to well up in Sara's eyes.

"I also love Olllie very much and should've never left him. He's the one who truly made me feel whole and reminded me of my humanity when I returned home. I thought I was dragging him into the darkness but now I see that he was actually leading me to the light. Everything you've told us and seeing how our lives are so parallel also makes me certain that our relationship is meant to be", she said, and then turned her attention towards Oliver. "And yes Ollie, I will definitely marry you. A thousand times yes. And I am also ready for our souls to be reunited", she finished, causing Oliver to lift himself up, place his hands o either side of her face, and begin kissing her passionately to which she eagerly reciprocated until they parted for air.

Clotho smiled at the beautiful sight and then said to them, "Since the two of you have expressed your feelings toward one another and have bonded yourselves with the promise of marriage, I now begin the process of restoring your shared soul." She then had Oliver and Sara join their hands together and after saying some ancient chant, placed her hands on their joined hands. Immediately, a ring of dazzling colors began swirling rapidly around them and caused what felt like a magnetic tug which drew Oliver and Sara closer together, the light around them glowing brighter and brighter until they merged, literally becoming one being.

Eventually the light faded and Oliver and Sara were separated, but in no way were they the same as they were before their merge. What they felt between themselves was indescribable and surreal. It was as if their relationship had ascended into a higher and more spiritual plane of existence. They could feel each other's hearts beating as though it was their own hearts and they could hear each other's thoughts just as Clotho revealed would happen. In addition, Oliver's memories became Sara's and hers became Oliver's, giving them an intimate knowledge of each other's lives and what happened when they were separated and also after Sara's death. Oliver learned about how Sara was found by Nyssa, her training and induction into the League, her relationship with Nyssa, the moment she decided to leave the League, and the thoughts and emotions that came with those moments. Sara on her part learned about what happened to Oliver after the Gambit, his mission during the year before she returned home, everything that happened after her death from Oliver's viewpoint, and of course, his thoughts and feelings during those events.

"This is amazing", Sara stated in awe. "I can hear and feel everything you're feeling Ollie. This is truly breathtaking."

"You're right Sara, this is beyond incredible", Oliver responded in agreement. "And there's no one I'd rather experience this with."

"Me neither", Sara stated with certainty while smiling up at him.

"Now that the two of you are one again and have rekindled your relationship, you are now ready for your final battle against Malcolm and it's coming very soon", Clotho said to them. "It's imperative that you win and finish this conflict once and for all. Otherwise he will continue to come after you in all of your following reincarnations and the darkness will continue to win against you. Neither of you must allow that happen. Are you ready to fulfill your destinies and do what needs to be done?"

Oliver and Sara turned their attention back towards the Fate before them and stared at her resolutely.

"Yes, we are ready. Ready to end this madness so that we can finally live in peace and experience what our future holds for us without Malcolm continuously ruining it for us", Oliver answered with conviction.

"Everything my fiancé said, I second it", Sara added while taking Oliver's hand and squeezing it.

"Then I bid you both farewell and wish you success in stopping Prince John or Malcolm as he now calls himself and grant the full blessings of myself and my sisters for your future", Clotho responded with a bright smile. "And know that we will always be there to protect and watch over you." Clotho then used her powers to send them both back from where she summoned them and where their respective teammates were waiting for them to awaken, now relieved when they finally did and peppered them both with questions as to what happened. Oliver and Sara then resumed the missions which they'd been respectively conducting before being interrupted by Clotho while eager for the day when they'd be reunited permanently and anticipated their final confrontation with Malcolm. They were however certain that as long as they had each other along with The Fates backing them, they would succeed and end this conflict once and for all.

To be continued

A/N Just so everyone knows, I don't know how Marian died according to the "Robin Hood" legends, but I decided to write her as being killed by Prince John because it served the purposes of this fic. As for Robin, he was killed by a nurse who either hated him for some reason or hoped for a reward from his enemies, so she did one of those bloodletting procedures they did back in the middle ages but let too much blood flow out and as you know, loss of blood is what kills you. A friend of Robin's managed to stop her but it was too late. He and Robin did manage to exchange a final goodbye. Sad story.
