"King of the Ground"

When mankind lived on the ground, many never realized that they were living within two worlds. There was a world that held the humans and then there was a world where the supernatural thrived upon.

[This is a collection of unconnected oneshots that share the same prologue…a history that involves "Supernatural"].

How will the 100 react to uncovering two worlds at once? Bellarke undertones.

Tag on to 2x16 ("Blood Must Have Blood, Part Two") of The 100.

Bellamy refused to look at anyone else as he walked into camp. He didn't want them to see his emotional turmoil through his eyes. The adults may not pick up on it when they first look at him but he knew members of the 100 would. No matter how hard he put up a strong front, he and the 100 have been through enough together to notice each other's small quirks.

He was too focused on trying to keep it together that he almost ran into Lincoln, who was waiting for Bellamy just inside the gate. Lincoln had watched the goodbye between Bellamy and Clarke while Octavia went to check on Raven.

"She'll be fine," Lincoln told Bellamy once he was within range. After the last few days, Lincoln knew that Clarke would prevail in whatever came her way.

Bellamy stopped and scoffed at the statement. "She has no plan, no destination in mind." He turned his disbelieving eyes to his sister's partner, "Where is she to go?"

"Wherever the King goes, she'll follow." Lincoln told him without hesitation.

Bellamy frowned, "What?"

"The deal you made with the King," Lincoln reminded Bellamy and when he saw a flicker of recognition in the younger man's eyes, he continued, "If you succeeded with your end of the deal, the King will follow through with his promise."

Bellamy's frowned deepened at the thought. He remembered meeting Lincoln's so-called King just before they had reached the Reaper tunnels. Bellamy didn't want to stop to entertain this self-proclaimed King as he was focused on Clarke's mission and their people inside Mount Weather. However, Lincoln insisted that Bellamy hear the man out or he'd greatly regret it.

"But I don't know if I succeeded or not." Bellamy confessed with a sigh.

Before Lincoln could give any reassurance, Bellamy hissed in pain as his right wrist felt like it was on fire.

What the hell?

MEANWHILE:

As Clarke walked away from Camp Jaha, away from Bellamy and all of her friends, she tried to keep her composure together as she ventured into the woods. Her vision became a little blurry as she remembered leaving Bellamy at the gate, telling him to watch out for their people for her. She didn't want to leave him and yet she had to.

She didn't have a plan. All she knew was that she couldn't go back to Camp Jaha. She couldn't be reminded of all the lives she killed in order to save her people. She wasn't a killer and yet that is what she became to save them, her friends, her family.

What am I going to do?

"Congratulations," Clarke swerved around and saw an older man leaning by a tree that she just passed, though he wasn't there when she did. "You completed the mission. You rescued your people." He commended her before he pushed off from the tree.

Clarke stepped back, "I did what needed to be done." She may have sounded confident yet she wasn't on the inside. She felt guilty for all the lives she ended.

"I'm not here to judge Clarke," she tensed at the sound of her name on the stranger's lips. "I know what it means to do anything to get back the ones you love." He took a step closer to her, "I know what it means to take a life knowing that it was the only option and yet having the guilt eat you up for making that decision." He sighed with a faraway look in his eyes, "I understand more than anyone."

Clarke stared warily at the man, "Who are you?" He was an older man (possibly younger than her father had been) dressed up in warrior gear that resembled Lincoln's and he had one tattoo exposed along his neck until it reached the hairs on his neck. He had a short haircut that seemed to be caked with dirt and mud. His eyes were a piercing green yet she got a chilling vibe as she stared into them. She couldn't read them and yet she could tell that he was dangerous just through his stare. His stance just made him all the more intimidating too and it was like he was emitting some sort of energy from him, a dangerous power.

The man laughed a bit, "Let's just say I'm your most powerful ally around here. And you have Bellamy to thank for that."

Her eyes widened, "Bellamy?"

The man nodded, "While Bellamy and Lincoln were on their way to Mount Weather together, I intercepted and stroke up a deal with him."

Clarke gulped at the thought as Lincoln (or Bellamy for that matter) never brought up the encounter to her, "What kind of deal?"

The man started to circle around Clarke, "If Bellamy got my brother out of that mountain then he'd have my full allegiance to him and anyone he cared for until the day I died."

"And did he?" Clarke questioned as she remained still while her eyes tracked the man who continued to circle around her.

The man smirked and stopped in front of her, "Clarke, I'd like you to meet Sammy."

"It's just Sam." Another voice greeted her from behind as the leaves rustled around him, causing Clarke to whirl around and face another man, a taller man with fresh cuts and bruises on his face, his long hair in disarray and similar warrior gear hung over on his long stature. She felt another source of energy coming from him too. "It's good to finally meet you Clarke."

"Likewise," Clarke gulped, "Sam." She didn't understand how they both knew her name.

Sam tilted his head as he stared at her, it felt like he was looking for something in her yet all he did was stare at her. It was only a few moments before he gave an annoyed look at his brother, "Apparently you haven't introduced yourself properly yet brother. Hasn't she been through enough already?" He chided.

The older brother scowled and Clarke could have sworn that the atmosphere around her became electrified, "You're back less than a day and you're already ruining my fun."

Sam scoffed, "It's what brothers do Dean and besides," Sam's stare hardened on his brother, "she eliminated your mountain problem for you. The least you could do is cut her some slack and give her some answers."

"We never would have had a mountain problem if you had just let me burn the place down before they figured out how to keep me and my army out of there." Dean growled at Sam and Clarke couldn't help but fear what would happen if the brothers' fight escalated. The only fights between siblings that she was ever exposed to were between Bellamy and Octavia and yet it was never like this. It didn't feel like this.

Sam laughed without humor, "So now it's my fault?"

The atmosphere around her intensified some more. She didn't know how but she knew the brothers were the cause behind it. She needed to say something before they ripped each other, and her, apart.

"Um, Dean?" Clarke interrupted, causing the bickering brothers to focus on her again, "You're Dean?"

Dean smirked. The darkness around him lightened a bit yet the intensity was still there.

Sam rolled his eyes yet he slowly calmed himself down from his anger. "Since you are originally from space, Clarke, allow me to formally introduce you to my older brother, Dean Winchester." Sam gestured towards the first man Clarke had met.

Clarke turned to face Dean, "Winchester?" She questioned, as the name sounded familiar yet she didn't know why it did.

Dean watched her closely, "Yeah, why?"

With the way he was looking at her, Clarke got the feeling like he was looking for something. It was like he expected her to recognize the name. She kind of did and yet she didn't know where or why. "It's nothing." She dismissed softly.

Sam nodded, "Alright, well that's Dean and he's also the King of the Ground."

Clarke's eyes widened, "King of the Ground?"

Dean shrugged, "Have been since 2050."

Clarke's eyes widened as that was the year that the nuclear apocalypse started, 97 years ago, and yet Dean barely looked like he was in his mid-30s, "How's that possible?"

"Long story," Dean dismissed with a wave of his hands, "Maybe I'll share it sometime with you."

Clarke was confused, "But Lexa…"

"Was just a Commander that's in for a rude awakening when I get back to Polis," Dean interrupted with a growl and Clarke could feel the atmosphere around her shift again. "First Anya disobeyed and then Lexa," The older man continued to snarl, "I swear, these women think they could undermine my authority when I'm away. Well they are sadly mistaken! No one is immune to my wrath." The atmosphere around them was electrified once again.

"Well except for Clarke," Sam interrupted his brother. He was unfazed by his brother's violent mood.

"Yeah," Dean blew out a breath and stared at Clarke, who felt the intensity around her lessen greatly, "except for you. Originally you were exempted from my wrath because of Bellamy's deal but you proved yourself today Clarke."

Clarke flinched at the mention of her recent actions. She didn't want to hear how she proved to him that she was a killer. She didn't want to hear that she's as ruthless as the grounders she's met.

She was so disgusted with her own decisions that she didn't register that Dean had moved closer to her until she felt her chin being lifted upwards, until her eyes met his. And the look he gave her surprised her. She didn't fear his stare, not like she originally did, instead she felt like he understood her. Like he knew just what she was feeling, like he's been where she stood now. Sure she saw the look from Bellamy before she left him at the gate, but to see it on someone who just met her, who wasn't there when she made the destructive decisions that she did…it somehow made her feel like she wasn't condemned. She didn't feel like a monster.

"You were willing to go above and beyond for your people. You're willing to do the dirty work yourself instead of assigning it to someone else." Dean explained and for a moment, she thought she saw a spark of pride for her in his eyes. "And Bellamy showed great loyalty towards you and your plan to save your people." He smirked at the mention of Bellamy, as if he knew something that she didn't.

"You two are quite a team." Sam added in from behind her.

Clarke looked over her shoulder, "We're not anymore."

"Yes you are," Clarke looked back at Dean, "You two are connected because of the experiences you faced together and now you two are connected to us through his deal."

Sam moved to stand beside his brother, placing them both in Clarke's sights, "An alliance with me and Dean is invaluable because Dean basically rules over all the clans on the ground." Sam explained and Clarke watched as a dark yet smug expression appeared on Dean's face. "And because Bellamy freed me from the mountain…"

"Something others failed miserably to do." Dean grunted with displeasure.

Sam placed a hand on Dean's shoulder and squeezed it tightly, as if the physical contact would ensure the older man that his brother was indeed back by his side. "My return is something Dean has been trying to achieve for years." Sam turned to face Clarke and she could see a tinge of sadness in his eyes, sadness she could only assume came from one being separated from family, "He would have gone in to rescue me himself but the Mountain Men took precautions that prohibited him from entering. Because Bellamy freed me, he proved his worth to not only me but to my brother as well."

"And as Bellamy's reward, I'm giving him and those closest to him immunity." Dean smirked when he saw Clarke's eyes widen at his words, "Consequences go to those who attack people who I've granted immunity to. You no longer have to worry about having a target on your back Clarke. No other human will attack you again for as long as I remain in power. However the immunity is lost the moment I suspect betrayal."

Her eyes widened, "We can live freely?" Clarke couldn't believe what she was hearing, "And all because Bellamy rescued Sam?" Did Bellamy truly grant them peace on the ground?

"You and Bellamy earned this," Sam clarified, "It was your plan Clarke to infiltrate the mountain. Bellamy just executed it and struck the deal."

Clarke looked away as she tried to process the news. She knew they weren't lying. The amount of power she felt radiating off of them was enough to convince Clarke that they did hold the power to uphold this immunity. She could go back to living life like she had those first few hours they landed on Earth, before they realized that there were other survivors on the ground. Back to living a life where they only had to worry about surviving nature, back to living a life where they didn't have to fear that they were being hunted down.

A warmth on her shoulder brought Clarke's attention back to the brothers. She turned as Sam withdrew his hand from her shoulder.

"There is just one last thing we need to do before the deal is solidified," Sam explained as he stepped back.

"What is it?" She asked as she looked between them.

Dean stepped forward, "Well when I initially made the deal, I started the sealing through Bellamy but since he views you as his partner, I can finish the sealing through you." Sam stepped back and drew a circle and a few sigils into the ground around them with a stick.

"How?"

"A simple ritual," Dean shrugged like it was no big deal. "It's one that can be duplicated yet the success only occurs when me and Sam perform it together."

Clarke nodded, "Will it hurt?"

Dean scoffed, "Not for you."

Sam joined them again and held his hand out to Clarke, "Your right arm please."

Clarke placed her right arm into Sam's outstretched hand as Dean exposed his right forearm, revealing the strange mark on it to Clarke. Dean withdrew a jawbone blade from his belt. Clarke gulped at the sight of the odd weapon.

"Cup your left hand," Dean instructed and once she did, Dean took his blade and sliced into the mark. He held his arm so that he bled into Clarke's cupped hand.

When he saw her flinch, Sam told Clarke to stop. "Don't let the blood drop," he said quickly.

Even though Clarke saw her fair share of wounds and blood, the feel of it pooling in her hand freaked her out. The crazy thought of drinking it entered her mind and she really hope that wasn't the ritual they wanted her to do.

When there was enough of Dean's blood in Clarke's hand, Sam dipped his finger into his brother's blood and drew a symbol onto Clarke's right wrist. After staring at it for a while, Clarke noticed that the symbol was the inverted version of the mark that Dean cut into on his forearm. If Clarke were to hold her wrist up, as if to raise her hand, then the symbol would match Dean's when his arm is straight down.

Clarke was so into her observations of the two marks that she didn't hear Sam's chanting until he told her that he was done. She looked down at her new mark again but instead of finding a bloody mark on her wrist, there was a red inked version of it into her skin. She uncapped her hand, releasing Dean's blood from her grasp, and rubbed at the new mark a few times but she was shocked to find that it was permanent.

"What the hell?" She looked at them with wide eyes, "You branded me?"

"Simply speaking yes," Dean pulled out a makeshift rag and wiped the blood up from his arm.

When it was clear that Dean wasn't going to say more, Clarke turned to Sam.

Sam sighed for his brother's attitude and answered Clarke. "You, Bellamy and those closest to his heart will now hold that brand like you do now." He pointed down at her new mark, "It's to show people that you are part of the King's inner circle. That you are to be untouched."

Clarke frowned at the mark, "Why this symbol?" She didn't get the significance, especially when it looked like some altered version of the letter F.

Dean removed the rag and showed Clarke the cleaned, and surprisingly healed, mark on his forearm. "This is what makes me so powerful Clarke. This Mark was given to me by Cain."

"Cain?" Clarke interrupted as she looked between them, "As in Cain and Abel?"

Dean nodded, "It's what has kept me in power for all this time. And since I got it, I've been trying to find a way to get rid of it but I can't, not without burdening someone else with the consequences that the Mark brings them." He placed his hand over the mark, covering it up from her view.

Clarke frowned, "Consequences?"

Dean signed before he closed his eyes for a moment before opening them again to stare at her. Clarke gasped and involuntarily took a step back. Instead of the piercing green eyes she was just looking into, Dean stared back at her with pitch black eyes. She never saw anything like it. Who was this man? Was he even human?

Dean smirked before he blinked his eyes back to normal. "That never gets old." He mused with a quick laugh, "Before I got the Mark from Cain, I was human. I only agreed to accept the Mark because it meant killing a great evil that walked the Earth. Unfortunately once I killed the bitch, the Mark craved for more blood."

Clarke noticed how Dean started to rub his hand over the Mark in question.

"I resisted for as long as I could but the more I denied the Mark, the sicker I got. It got to be so much that I thought of killing myself to end it." Clarke's eyes widened at Dean's admission, "The pain my body was in was too much to handle."

"Instead Dean was killed," Sam added with a forlorn look in his eyes, as if he were remembering that moment again.

Clarke's eyes widened as she looked between the brothers. She waited for one of them to tell her that Dean didn't actually die and that Sam was just exaggerating the situation or something. It never came.

"That should have solved my problem but it didn't." Dean scoffed at the false hope, "I woke up an hour later as this…thing and my killer died immediately after I had reawakened." At the mention of his killer, Dean looked pleased by their unexpected demise. As if thinking that his killer got what he deserved for killing Dean to begin with.

Clarke gulped at the thought.

"Apparently the legend behind the Mark of Cain was true," Sam continued for Dean, "No man shall kill the bearer of the Mark for if they succeed, it would be a short-lived victory for the killer as the bearer of the Mark will reawaken while their killer will experience the bearer's death tenfold shortly after the reawakening."

The more Clarke listened, the more the myth returned to her mind as she remembered her readings back on the Ark. She remembered how she would comb the digital archives for stories about how life on Earth was like and while searching, she'd come across stories of how the human race began. Many included tales of Cain and Abel, the first brothers. She remembered the tale of how Cain killed his brother, making him the first murderer. Cain was then cursed with the mark as a warning to others to stay clear of Cain for any harm or fatal deed aimed toward him would result in a greater punishment from God.

While still processing the news that the stories of the first brothers were real, another thought came to her mind. "So you're technically immortal?" Clarke asked as she looked to the invincible King.

Dean nodded, "Yes."

Clarke looked to Sam, "Are you immortal too?"

"My survival remains a secret," Sam averted with a smile, "Another story for another time."

Clarke nodded before she looked down at her new tattoo, "And this alliance?"

"Will continue long after you've lived out your life," Sam finished, bringing her attention back to them. Sam gave her a soft smile, "If there is no betrayal, your descendants will be protected Clarke."

"What the hell?" Bellamy cursed as he looked down at the odd new tattoo on his right wrist.

Lincoln walked over to Bellamy and looked down to where Bellamy was staring at. Lincoln smiled at the familiar tattoo.

"It looks like you completed the deal after all." Lincoln announced before he gave Bellamy a pat on the back.

"What?"

Lincoln removed his wrist-cuff on his right arm and revealed the same red tattoo on his own wrist.

Stunned by the similarity, Bellamy moved his wrist to align it with Lincoln's. The tattoos were identical.

"It's the Mark of the King. Those who have it are known to be part of his inner circle, a coveted place to be. The King's inner circle consists of people that he trusts, that have proven themselves to him." Lincoln explained.

Bellamy started between the two tattoos, "I've earned his trust?"

Lincoln nodded, "Yes. The Mark of the King can only be granted by both the King and his brother. You've achieved what others have tried their entire lives to gain."

Bellamy frowned, "He doesn't give his Mark often?"

"No."

"Then how did you?"

"Initially my mother proved herself to the King and when I was born, I had a faded version of the Mark on my wrist." Lincoln started to explain as he put his wrist-cuff back in place to hide his tattoo, "A faded version shows the King that I'm a descendant to a member of his inner circle. Once the descendant proves their worth to the King, the Mark darkens and turns red."

"How does one prove their worth?" Bellamy asked as he started to roll down his sleeves so he could hide the tattoo from prying eyes.

"No one really knows what the King looks for." Lincoln confessed with a shrug, "Do you kill a savage beast because you can or do you do it to save another? Do you save a village from disaster or would you save yourself? Do you sacrifice yourself to save another? Would you give your life to save the King? Whatever the action, the King always knows where your heart truly lies on the subject."

"So basically you can't do a heroic deed and expect something in return?" Bellamy said after some thought.

Lincoln nodded, "Basically. The King always knows your true intentions."

"So when I saved his brother, despite the deal I made with him, I proved myself?" Bellamy was still trying to understand the mindset of this King. On the one hand, Bellamy didn't want to believe the power behind the title but then again, the sudden appearance of the tattoo was proof in itself that the King had power to use.

Lincoln pulled Bellamy off to the side for a bit more privacy. "You proved yourself by saving your people the way you did. You earned the King's trust because you gave him his brother back." Lincoln was certain of this reasoning, "For years he tried to get to his brother but the Mountain Men found a way to repel the King and his inner guard. Because of this, many tried to prove themselves by going after his brother for the King. The King knew they were only doing it to please him and yet he didn't care. He just wanted his brother back so he was going to reward the person who brought back his brother to him. That person happened to be you." The grounder finished explaining.

"But I made a deal." Bellamy pointed out, "I knew the reward if I were to succeed." His situation still contradicted Lincoln's story about the King's ways. If anyone before him that made a deal didn't get the Mark, then why did he?

"A deal was made because you aren't familiar with how the King governs the land. You were still skeptical." Lincoln clapped Bellamy on the shoulder again, "You should be happy Bellamy; you just acquired immunity for yourself and those closest to your heart."

Bellamy's eyes widened.

Lincoln smiled at the reaction, "You brokered the deal yet Clarke sealed it for you." Lincoln pointed down at the covered tattoo on Bellamy's wrist. "The sudden appearance of the Mark only proves that she's currently in the presence of the King and his brother."

Bellamy pulled back his sleeve a bit so he could see the mark again, "So she's safe?"

Lincoln nodded, "Even without your deal, I think Clarke proved herself today to the King."

Before Bellamy could ask anything else, they were joined by Octavia and Monty. Both of them were waving their wrists around and demanding answers for their sudden tattoos. Apparently they weren't the only ones that were close to Bellamy's heart.

*SPN*100*SPN*100*SPN*

A/N #1: I'm so sorry for the long wait. This idea since The 100 finale in March. I wrote 90% of it then but life got in the way. I finally got to finish it so I hope you guys like it. This marks a possible first encounter of the King of the Ground with someone from the 100 (in this case Clarke). What did you think of this version of the King? This King is many years down the line of what we initially see Demon-Dean as in episode 10x01-10x03.

A/N #2: Thank you so much for all of you that are reading this! It means a lot to me that you're giving this combination a chance and sticking around. Thanks for your suggestions, I'll definitely give it some thought. Stay tuned for more!

Other Projects: Aside from life worries getting in the way, part of my time has been dedicated to this new youtube channel that I created. I started posting my 'after show' videos there which are just my initial thoughts of an episode to any show I'm interested in (ie: Supernatural, Arrow, Lost Girl, later The 100 when it returns, etc.). You can check it out here [attaching weblink below after dot com] or back at my tumblr page and livejournal page (the channel is attached to those too).
