Hey guys i'm back! Thank you so much for the reviews, faves and follows! I shouldn't have wrote this... It's the middle of block and i should be studying not writing fanfics :/ But oh well! I did it anyway ^^.

Just so everyone knows:

A dragon's age is their human age multiplied by 4. Each season is considered a year ^^

Eren:

- Age 13 in human years

- Around age 52 in dragon years

- Fur-dragon

Levi:

- Age 17 in human years

- Age 68 in dragon years

- Dark dragon

I will add to this as more characters are introduced ^^

Chapter 4

Blue-green eyes stared intently at the three men, as if awaiting for their next move. For a moment, Levi had no idea what he was looking at. There was no doubt that the creature before him was a dragon, the scent giving that fact away; however, this was no dragon Levi had ever laid eyes on.

Instead of smooth scales, the dragon was covered in ruffled light brown fur. There were two small horns just above its large cat-like ears and chestnut brown fur adorning the top of its draconic head. What intrigued Levi the most was the large feathered wings situated on his back. No dragon he had ever met looked anything like Eren, but he did recall some legends and stories that described rare dragons with feathers.

Levi tore his gaze away from the creature to study the two human's expressions. He wasn't disappointed. Nile was staring in utter disbelief while Grisha looked as though he had just shit himself. The dragon smirked in amusement at his observations. He honestly hoped Eren would tear them both apart so they could leave for HQ.

The dragon didn't even realise that he had zoned out until he heard the engine of a vehicle start. His head snapped towards the van that was currently speeding down the street before returning his attention back to Eren… Who was staring directly into his own steel grey eyes. It was rather unsettling, but Levi knew he could easily win against this creature, so he had nothing to fear. He decided to try and talk to the beast first, before initiating an attack.

He stood up slowly, ignoring the sharp pain from his chest wounds. He was slightly angered that Eren didn't bother to chase after the M.P.s, but he could tell the brat wasn't himself so it wasn't really his fault for letting the bastards get away.

"Oi, Eren. Play time's over, so get your act together," he spoke in a bored tone, taking a few steps forward. His command was ignored, a low growl being the reply. As Levi got closer, the fur on Eren's back began to bristle and he began to bare his teeth threateningly.

The older dragon sighed in pure annoyance, halting his approach. Eren hadn't made a move yet, but Levi was sure an attack would take place soon. And he was right.

The fur dragon charged with a roar at Levi, who used his fast reflexes to easily dodge sideways. It seemed his evasion only angered Eren further, causing him to turn and swing his tail harshly in his direction. The attack missed again as Levi had flown upwards and out of reach. It seemed Eren hadn't figured out how to fly yet, so he used that to his advantage.

Levi growled at the situation. He couldn't get through to the boy, which meant he would have to try and tire him out… or beat him up until he couldn't move. Either way, he couldn't leave the rampaging dragon on his own. Why was he even like this anyway? He had never heard of dragons mindlessly attacking before… His thoughts were interrupted when a blast of white energy narrowly missed his right wing.

Oh so that's how he wants to play… Too bad his aim is shit.

"I apologise in advance, brat. Don't take this personally…" Levi uttered before completing his transformation within a black cloud.

His full form wasn't as impressive as other dragons, but he made up in skill as he had a lithe but strong body structure. A perfect combination for agile movements and powerful blows. He had a limited amount of sharp appendages, including only one set of white horns and standard silver back spines, however it was all he needed to take down even the toughest opponents. It was what got Levi his reputation of being 'dragonkind's strongest', a title he had come to ignore. He hated that everyone looked up to him as if he was some God, but he eventually gave up in telling others off.

Now that he was in his true form, Levi could easily outmatch Eren in speed, agility and strength. He swooped down, tackling the younger dragon to the ground. In a frenzy of black and brown, the two creatures relentlessly fought. Somehow, Eren ended up pinning the other down, fury burning in his eyes. The fur dragon snapped his jaws at Levi's neck in an attempt to use a killing blow, but the black dragon merely threw him off with a strong kick from his back legs.

"Well… I certainly didn't expect it to take this long…" Levi muttered under his breath as he prepared his next attack. Eren had scrambled to his feet in an instant, hissing in anger. He charged again. This time, Levi didn't dodge, but managed to knock Eren out by slamming the blunt side of his tail against the side of Eren's head. He fell sideways, crashing to the road with a low thud.

"You put me in a shitty situation, brat…" Levi had no idea of what to do. He couldn't just leave him… but there was no way that he would carry the kid all the way to HQ.

He was about to yell in frustration when he heard a low voice. Assuming it was Eren, since there was no one else around, he cautiously approached the brat and lowered his head slightly.

'I'll kill you all…'

Eren's mind was a haze, as if it had been pushed back from reality. His vision was distorted and dark, making it seem as if he was underwater. He could neither hear or speak as well. The brunet felt trapped within his own head, giving him the sickening feeling of dread. He had no idea what was going on or where he was, but one thing was certain…

He had a strong desire to kill. It was as if the idea echoed within his head, calling out to him. Just one kill wouldn't be enough to satisfy him, he had to take out everything that moved.

It seemed as though he was in that state of mind for ever, until his distorted vision suddenly turned black and a voice began to make its way into his head. He tried concentrating, only to hear the annoyed words 'I don't have time for this shit'. Eren knew that speech pattern… it could only be…

Levi!

Eren's eyes snapped open and in an instant he was on his feet. He glanced around quickly, noticing the lack of the Military Police. Odd… he thought before his line of sight ended on Levi, who stood with his arms crossed in full human form.

"Umm… what happened?" his voice hinting at his current confusion. The older male narrowed his eyes at Eren in pure annoyance.

"You don't remember anything? Nothing at all?" Eren tried really hard to remember, but nothing made itself known. He shook his head, causing Levi to sigh.

"I recall being shot," he said as he raised his hand to his chest, "but… after that it's all a blur."

"Then I'll fill you in. In short, you went mental, scared off the Military Shits and then attacked me. Of course, I beat you and now you and I are having this conversation."

Eren blinked, "I… went mental?"

"Do I have to repeat myself? Yes, you shit, you went ferrel. Also, were you aware that your dragon form is some sort of mutt?"

"Wow, I feel really offended right now," Eren deadpanned. He was still sceptical that he himself was a dragon, but that didn't mean Levi could insult his true form.

The dark dragon rolled his eyes, "You were covered in fur. I've never seen that before, so if you know something you better explain. Was your mother a fur-dragon?"

"What?! My mother… but…! I don't know anything!" the boy shouted angrily, causing Levi to cringe slightly at the sudden increase in volume.

"Urgh, whatever. Let's just hurry up and get to HQ… I was meant to be there hours ago."

"Why do I have to go? I'm not a part of this!" Eren shot back in defiance.

"For starters… you are a new breed of dragon, something that hasn't been found in centuries. You are also unstable, so leaving you alone would only turn out disastrous for both humans and dragons. You obviously have no clue about what you are and I believe you deserve to know. Besides, now that the M.P. saw your little show, they're bound to come after you. Need I say more?"

The silence he received was the answer he needed, "Good, now follow me."

It had been at least five minutes before Eren began to fidget. He was still curious about this 'Underground' place and dragons themselves. Maybe Levi would answer some of his questions?

"Um… Levi?" a grunt was his reply, "how did you know I was a dragon?"

"Seriously brat? Can't you save the Q and A for someone else?" he responded instantly. It wasn't as if he didn't want to answer questions, but some explanations were better off being told by Shitty Glasses or Eyebrows. Levi wasn't the best at in depth explanations…

"Oh come on! I just found out I'm a dragon and my own father is trying to kill me. Don't I deserve a little closure?"

"Tch, fine. But I'll only answer five questions. The rest you can ask Hanji when we get to HQ." Levi could see Eren grin in victory from the side of his vision.

"Ok question one! How did you know I was a dragon?"

Levi gave Eren an 'are you serious' look, "Surely you have been able to smell the difference by now, brat. Dragons and humans have vastly different scents. It's been proven that humans typically smell worse than our own kind."

"Huh… So everyone who smells bad is human then? But Armin and Mikasa smell normal…"

"Look, a lot of brats that go to your school could be dragons. It's not like you're the only dragon attending a human school." Eren thought about that. So did that mean his friends were dragons as well? Did they know?

"So, um… why am I a dragon if my parents are humans?"

Levi scoffed, "It's obvious Eren. Your father is no dragon, especially considering he now works for the M.P. So the only explanation of how you are of dragon blood is that your mother is one."

"Maybe…" Eren went quiet. It began to mildly concern Levi since the kid was always loud and boisterous. The dark dragon wasn't heartless, he did care for his comrades and acquaintances, so he decided to ask.

"Oi, brat? Did I say something wrong?"

Eren tensed slightly, "no… It's just that my mother died a year ago, so I wouldn't know."

"I see… do you have any more questions?"

"What do dragons do? Let me word that better… What is a dragon's role in society?" Eren was glad for the change in topic. Maybe Levi wasn't cold-hearted after all.

"It depends. We have multiple duties, but some prefer to remain undercover as humans and away from trouble. In the Wings of Freedom resistance there are trainers, undercover agents, scientists, strategists and assassins. Unlike others, I'm a part of the Special Operations Squad, more specifically their leader. It's my job to lead the most dangerous missions, normally infiltration. Only the best of the best are promoted to my squad."

Eren's eyes lit up, "that's so cool! How do you become a part of your squad?"

Levi smirked slightly at his enthusiasm, "You need to master your division, be in the top ten in your class and be recognised by me or Erwin. It's a tough and dangerous path Eren, so be warned if that's what you're aiming for."

"Yes! I want to become strong, so I can help stop this stupid war between the dragons and humans! No one deserves to live in fear when there is nothing to fear."

"Even so, it's not easy to achieve. Many great dragons have fallen to the Military Police, and even more have been captured. You'll need more than determination to even slightly make a difference," Levi had seen what Eren's dragon form was capable of, and he saw the potential in him. Only, the brat would have to train hard to control his true form.

"I'll train harder than everyone combined! I will join the Wings of Freedom, and I will make a difference!" Eren exclaimed, causing Levi to glance in his direction.

"I'm sure you will. Now, you have one question left so make it quick."

Eren thought for a moment, "Can you explain the whole division thing?"

"I will tell you a little. Hanji is better with this sort of stuff though. A dragon's division is basically the element they are able to control. For me, it's darkness. The known division range is fire, electricity, darkness, earth, wind, light and water; however, branches of the divisions, known as sub-divisions, also exist. Things like ice, metal, plasma, plants and so forth. Sub-divisions are rarer and harder to come by because of the way the energy has to be manipulated and such. Something about developing divisions; Hanji would be able to explain it a lot more."

"When I went 'mental'," Eren used air quotes when he said 'mental', "did I use any elements?"

"You've already asked five questions… but since this one is only short… I recall you using light, but I could be wrong. It didn't feel like light since it didn't affect me as much as it should have."

"What do you mean?"

"Since I am in the dark division, light would have impacted my energy manipulation. But it didn't, so I'm going to ask Shitty Glasses about it later. Now shut up and pick up the pace. We still have a little way to go."

Eren remained quiet for the rest of the journey, gradually getting more and more excited to see the Underground HQ of the Wings of Freedom resistance.

I will be a part of the Wings of Freedom if it's the last thing I do!

So! For one of the chapters i'm going to have Hanji explain as much as possible about the dragons of this universe. Any questions that you (readers) ask will be answered by Hanji who will be explaining to Eren in a future chapter. So keep that in mind! Want a question answered in the story? Just comment!
