Hi, everyone! This is my first ever fic (I've written like a billion but never posted any).

Just so you know, most of the events are canon except for the whole soulmate thing and a few details that come with it.

Disclaimer: I don't anything except the original characters and the plot.

All mistakes are my own.

Clarke

No one knew when it would appear, or even if it would; nor could they guess what it would like. Such is the nature of soulmate tattoos or marks. That is the way it has always been.

Throughout history, many had been fortunate to have their tattoos appear on their bodies and some were even more fortunate to meet their soulmate, the one other person in the world that would complete them truly, whose tattoo matched their own.

For Clarke, the hope of possibly getting her soulmate tattoo was completely destroyed once she was put into solitary confinement. There were only so many people on the Ark, and if her tattoo hadn't appeared yet, the chances of it being revealed while stuck in a Skybox – waiting to be floated – were practically non-existent.

She envied her parents. She had seen how glorious the bond between two soulmates could be and she wanted that for herself. The incredible love that could be shared between two people was all that she could hope for in her life. It was something that most people spent their whole lives waiting to happen. But Clarke decided to give up waiting, what was the point? She was going to get floated anyway.

However, this changed for Clarke the moment her feet touched Earth for the first time. She felt a strange tingling in her lower back and she knew, without a shadow of a doubt, that it was her tattoo. And she was not the only one.

As the 100 ventured out of the drop-ship, a number of them lifted their shirts or rolled up their sleeves to reveal tattoos of various styles that had suddenly appeared on their bodies. Many of them gasped in excitement at the prospect of meeting their soulmate, others looked on in envy.

Clarke refused to indulge in everyone's curiosity surrounding the tattoos and focused on making it to Mount Weather, on surviving. But when she did get a moment, she did find a reflective piece of metal in the wreckage. She lifted her shirt and jacket and looked back to reveal her tattoo. It was a large triangle made of three smaller triangles connected to each other at their points. The triangle at the bottom left was black while the other two were just outlined. Clarke didn't know what it meant and she forced herself not to think about it. Survival came first.

Lexa

It was common for the new Commander to receive their mark when they were chosen and Leksa was no exception. Her tattoo appeared when the Commander Spirit came to her; she was only eight years old.

She refused to allow anyone to see it, except for her mentor Onya. Finding her soulmate was not high on her list of priorities, training, uniting her people and saving them from the Maunon was.

However, Costia unexpectedly waltzed into her life. Her bright smile, contagious laugh, and bubbly disposition swept Lexa off her feet. But from the first moment that they met, she knew that Costia was not her match and Costia knew it too. That did not stop them from falling for each other, nor did it stop the Queen of the Ice Nation from cutting off Costia's head.

After that, Lexa shut her heart from any hope of finding her soulmate. Her duties were more important; her people were more important. She vowed to never let the heart rule her decisions again. If her people saw her as weak, they would turn against her in an instant. Love was weakness and she could not afford to be weak.

But in the dark of night, when all was quiet and there were no prying eyes, Lexa's mind ran through all of the people she had met on her travels. She knew that none of them had a tattoo that matched hers. No one matched the triangle made of three smaller ones on her back; the top one was black while the lower two were blank.

She cursed herself for having even a glimmer of hope.

That was until people fell from the sky.

Clarke

The fact that they were not alone on the ground scared Clarke more than she wanted to admit, but not because they were a threat to her life. What scared her was that it meant her soulmate was one of them. None of the 100 was her soulmate because everyone else who got their tattoo had shown it off and they didn't match hers. She hadn't told anyone about her tattoo and planned to keep it that way.

And in the midst of it all, Finn turned his attention towards her but despite his efforts, Clarke turned him down at every turn. He wasn't who she was meant to be with so why should she even attempt to pursue a relationship with him. She would just be leading him on and she wasn't cruel enough to do that.

Raven was something that she didn't expect to be a part of the picture and Clarke felt sorry for her. Raven had risked her life to come down to Earth, not just to save the people on the Ark but to be reunited with Finn, but he no longer had eyes for her. His eyes were firmly set on Clarke and soon he became desperate. He was completely convinced that Clarke was his soulmate even though he didn't have his tattoo.

Clarke didn't truly know how bad it was until she, Bellamy and Octavia arrived at Tondc to find that he had murdered 18 innocent people, just to find her.

After seeing how obsessed someone could be with having a soulmate, Clarke almost didn't want to meet her's, almost.

As Clarke entered the tent, she was very surprised by what she experienced. She had not expected the Commander to be so young, and she had definitely not expected to feel a force pushing her forward, directly from where her tattoo was, as her bright blue eyes met the forest green eyes of the Commander.

A feeling washed over Clarke at that moment, like a piece of the puzzle had fit into place. She knew who her soulmate was and she was sitting right there, tanned skin, braided brown hair and a jawline that had to have been sculpted by gods. Clarke had never felt such instant attraction in her life.

She did not let herself show her surprise, but she saw something flash in the Commander's eyes: recognition. She had felt it too, but the stoic face of the Commander remained firmly in place and negotiations began.

A few days later, Clarke killed Finn rather than let him go through the torture. She couldn't watch him suffer, nor could she do that to Raven, but he had to die. She needed Lexa and her army so that she could save her friends. It still hurt to have to drive that knife into his heart and it haunted her.

She secretly hoped that Lexa would come and comfort her that her soulmate would comfort her, but Lexa didn't. They had an unspoken agreement, made through moments of eye contact that they could not act on their bond.

They tried to keep their distance from each other, but the circumstances of the war forced them to be together often, and sometimes alone. The entire time, the force in their backs tried to push them together, but they resisted.

It was excruciatingly difficult for Clarke to resist. To know that her soulmate was right across the room and she could not be with her was slowly tearing the sky girl apart, but she couldn't give in.

They continued to deny themselves, but it wasn't until Lexa threatened to kill Octavia that their bond was first spoken of.

"250 people died in that village, I know you felt for them. But you let them burn."

"Not everyone. Not you."

It was the first time that either of them had acknowledged it out loud, but Clarke put her feelings aside and refused to give in, not while Octavia was still in danger.

That evening, when Lexa leaned in and their lips met, everything around them stopped and something inside the both of them shifted, another piece fell into place. It was a glorious feeling that Clarke desperately wanted to give in to. She would have given anything to fall into Lexa's arms, but she couldn't.

"I can't. Not yet. Not while our people are still inside the Mountain."

Their plan was successful. Indra and Octavia led the Grounder prisoners out through the Reaper tunnels. Lexa returned from the ridge, covered in blood and missing a few of her men, but she stood by Clarke as the door to the Mountain was opened. They fought together, subconsciously seeking each other out to ensure that they didn't lose each other. Together, they found Clarke's people and left the Mountain, however not everyone made it out alive. A few of the 47 were killed while trying to get out, many Grounder warriors and Ark soldiers were also lost, fighting to rescue their people.

The only ones that remained inside were those who had helped the 47 and those who were innocent. Some of the Sky people even volunteered to donate their bone marrow so they could return to the ground.

There were celebrations held at the camp, a great feast for both the Arkers and Grounders, not only to celebrate their victory but also to honour those who had died fighting.

Clarke and Lexa sat side by side as leaders and were approached throughout the feast by many of their people, to congratulate them on finally defeating the Mountain and freeing their people.

However, between the two of them, there was a nervous energy. Their thoughts preoccupied with each other and what they both knew was about to happen. The war was over; they could finally give in.

As the celebrations came to a close, most of their people had either retired for the night or were too intoxicated to notice the two enter Lexa's tent together.

Once inside, they just stared into each other's eyes and let themselves absorb everything, both of their backs throbbing at their closeness. After denying it for so long, this was the moment they had been waiting for. Clarke was the first to break eye contact. She walked to the table where she found a bowl of water and a cloth. She wet the cloth and moved to stand in front of Lexa again.

She brought the cloth up and began to clear Lexa's face of her war paint. Lexa closed her eyes and soaked in Clarke's gentle touch. She could feel her walls fall away and she did not stop them. Clarke was her soulmate. There was no reason for Lexa to hide from her because Clarke would always be able to see right through her.

After Clarke was finished, Lexa took the cloth from her and put it aside, never taking her eyes off of Clarke. Neither of them remembers who made the first move but a second later, their lips touched. It was gentle and loving, neither of one wanted to rush this moment as their lips slowly moved together.

Lexa brought her hand up into Clarke's hair, like their first kiss, her other hand snaked to Clarke's waist and pulled her closer. Lexa ran her tongue across Clarke's lip and Clarke let her in, her knees almost buckling at the feeling of Lexa's tongue against hers.

There was no battle of dominance, they were equals and took their time to explore each other.

Clarke could feel her desire growing, the pent up emotions from the past few weeks were floating to the surface and she couldn't wait any longer. She lifted her hands up and undid the buckle of Lexa's shoulder piece and let it fall to the ground.

Lexa pulled away and stared into Clarke's eyes with something that was not lust, it was something much more. Her green eyes were sparkling in the dim light of the tent as she took in every feature of Clarke's face.

They continued to undress each other, slowly, so they could take the time to learn each other's bodies. They shared kisses in between the removal of clothes and they would occasionally place a gentle kiss on each bit of newly exposed flesh.

Eventually, they were both down to their undergarments, Clarke in a bra and underwear; Lexa with a cloth bound around her chest and skin-tight shorts.

Lexa took Clarke's hand and led her to the back of her tent, to the area behind her throne, where Lexa's bed was hidden. Lexa sat down on the edge of the bed and pulled Clarke towards her. Clarke straddled Lexa's lap and ran her hands up Lexa's body and into her hair. She pulled Lexa into a heated kiss and gripped her braided hair.

Lexa's nails dug into Clarke's hips, and she felt the blonde moan into her mouth. She brought her hands up Clarke's back to the clasp of her bra. She attempted to undo it but could not figure it out especially while Clarke was still kissing her. Lexa felt Clarke smile against her lips and she removed her hands from Lexa's hair.

She pulled away from Lexa's lips and sat back in her lap.

"I've never been with anyone before," Clarke said, her voice barely above a whisper.

"Then we will not do anything you do not want to," Lexa replied, gently caressing Clarke's face, her eyes showed a kindness that Clarke had never seen before.

Clarke smiled. She undid the clasp of her bra and shrugged it off. She threw it to the side and felt Lexa's eyes on her. Lexa's hands continued to roam Clarke's body, gently caressing the skin of her hips as she stared.

Lexa's eyes drifted back to Clarke's, "Beautiful." She said.

Then she leaned forward and began to gently kiss along Clarke's jaw. She moved down to her neck and sucked lightly on Clarke's pulse, making the blonde gasp as heat shot through her body.

Clarke's hands intertwined in Lexa's braids again, tugging gently, encouraging her further. Lexa slowly left a trail of wet kisses down from Clarke's neck to the soft flesh of her breasts. She attached her lips around the erect nipple of Clarke's left breast and Clarke threw her head back and moaned. She ground her hips into Lexa's and felt the brunette moan into her skin.

Clarke's hand fell from Lexa's hair and undid the cloth that bound Lexa's chest. It fell away and exposed Lexa's tanned skin and her incredible body, covered in scars from the countless battles. Clarke lifted Lexa's face gently to meet hers again, their eyes filled with desire and probably love, love that was just waiting to be released.

Clarke was lying on her side, her head propped up on her hand, her other hand on Lexa's back as she slept. Her fingers slowly traced the tattoo that matched her own, she particularly focused on Lexa's black triangle at the top. She watched Lexa's face closely. It was the most peaceful that she had ever seen the girl and Clarke smiled to herself as she realised she would wake up to this sight every day.

Clarke leaned forward and placed a small kiss on Lexa's forehead. Lexa stirred and slowly opened her eyes. She caught sight of Clarke staring at her and pressed her face into the bed.

"You're staring." Her voice muffled into the furs beneath them.

"I know. I'm allowed to. I'm your soulmate." Lexa lifted her head and smiled at Clarke. It was the rare smile that not many had seen before and it warmed the sky girl's heart to know that she was privy to it.

Lexa shifted closer and kissed Clarke fiercely. When she pulled away, Clarke smiled and said, "I can definitely get used to that."

Lexa rolled onto her back and Clarke snuggled into her side, leaning her head on Lexa's shoulder and entwining their legs. Lexa's hand trailed gently up and down Clarke's back as she looked up at the roof of the tent.

"I feel almost complete," Clarke said quietly.

"Almost?" Lexa asked.

"It still feels like a part of me is missing."

"I feel it too. I believe it's the third triangle of our tattoo. We must have another soulmate."

Silence fell within the tent and they both reveled in the heat of their naked bodies against each other, finally feeling like they were on their way to being happy.

"Lexa? Do you think we will find them?"

"I do not know Clarke. We found each other and I had given up all hope of finding you, so it could be possible."

"Yeah, and even if we don't find them, I think we'll be okay."

The weather grew colder as the weeks passed and despite the war being over, there had barely been a moment of peace for either of the leaders. Plans were made and Tondc was being rebuilt; bone marrow transplants had started inside Mount Weather and the remaining people in the Mountain were moving to the ground. Food stores were being filled, furs collected and woodpiles stocked. From what they were being told, the Sky people's first winter on the ground was going to be a cold one.

Lexa and Clarke were spread thinly across their duties. Clarke helped her mother with the bone marrow transplants for some time inside Mount Weather before returning to Tondc to look after those still recovering from the battle. Lexa oversaw the resurrection of Tondc and the disbanding of her army. Occasionally she would forgo her Commander armour and assist building houses and clearing rubble with her people and the Sky People.

She could tell that her people appreciated seeing her like this, as not just a ruthless commander who ruled over them with an iron fist, but as a leader who cared for her people enough to help them rebuild what they had lost.

They kept their relationship a secret for some time, but eventually people started to notice there was something going on between them, namely Raven and Octavia. It turns out that Clarke and Lexa weren't being as discreet as they thought. After Raven and Octavia confronted Clarke about it, she and Lexa decided to tell their people.

It was well received and brought their people closer together. The Trigedakru developed even more respect for Clarke. It also allowed Clarke and Lexa to be more affectionate in public, no more stolen glances and sneaking into each other's tents at night.

They were happy, their people saw that and it added to their morale. Finding one's soulmate was possibly one of the most important moments for an individual and was always celebrated.

However, the two leaders did not tell their people about the third missing piece of their puzzle.

There had only been one recorded instance of three soulmates being connected in Grounder history and it was not received well by the people. The three soulmates were considered an abomination. They were hunted endlessly, despite having done nothing wrong. Eventually, they were captured and tortured. They had been forced to watch each other suffer through 'death by a thousand cuts'. Once they died, their bodies were burnt separately, the people mocking their bond until the end.

The idea of three soulmates was completely unheard of among the people of the Ark.

Lexa and Clarke thought it best to never reveal their secret, even if, by some miracle, they found their other soulmate.

The only ones that knew were Raven and Octavia. They forced Clarke to show them her tattoo and explain its meaning. They were sworn to secrecy, not even allowing Octavia to tell Lincoln, her soulmate.

Despite the fact that their relationship was now public, Clarke liked to convince Lexa to sneak out of the camp to spend the day among the trees, away from their duties. Lexa reluctantly agreed after she secretly told Indra that they would be gone for the day so that it would not cause a panic.

It was on one such trip that that everything changed.

Please feel free to comment, and ask me questions :)

I'd really like to hear what you think.

Also, I may not post regularly but I'll try. I've been writing this since the end of season 2 and finally decided to start posting it because of the approaching SEASON 3 AHHHH! I haven't finished it so I guess we'll take this journey together :D
