Prologue

500 years before the first Great Holy War...

Roaming the tall charred hills, of the country of Brittannia, he wandered, long blue hair flowing in the wind behind him, making his face more visible to onlookers wearing nothing but an emotionless visage, blue markings spread across his forehead and cheeks. His muscular body almost nude apart from the heavy cloak, short pants, and necklace with seven teeth, belonging to one of the most powerful and ruthless species known to ever live.

Hills charred, the once fresh green grass has become virtually invisible to the naked eye, instead now the once beautiful landscape is covered in blood and corpses of two different races. The smaller bodies belonged to the human race, once living normally not expecting today to be there last. However the most prominently seen race on the field is that of the owners of teeth such as the ones around this figures neck.

This race was that of the Dragons, a cruel and selfish race that thought themselves as much higher beings than that of the other species roaming the lands. However, not all 643 of the dragons on the field were dead, no there were still two more, one being our mysterious blue haired figure in his human form and, the other is a light green injured dragon currently trying to hold on for dear life.

"Damn you!!! Acnologia!, this is madness, why?!?!" It hissed, as the figure approached him, like a wolf would to a sheep

"Why ?" He questioned. "Tell me, what differs a tiger to another animal?" He asked calmly.

"What in the hell are you talking about?" The great winged beast demanded

Acnologia looked upon its suffering form, grinning in satisfaction at his own handy work against the creature. "Vengeance" he said causing the lizard to raise a non existing brow, wincing in pain as Acnologia put his foot upon the Dragons injured leg. "The tiger is known to be the most vengeful creature within the animal kingdom. However, there is a stronger much more powerful monster that also seeks revenge, against those that he hates most"

"NO! I Palzrinth, I-I will kill you, you won't b-be victorious, we c-cant lose to the likes of you!" The now named Palzrinth, eyes widening in realization to his enemies previous comment, the green dragon shouted gathering whatever strength he had left, all to stop this formidable foe in front of him.

It didnt matter the pain, it didnt matter the high possibility of failure, he will at all cost make sure that Acnologia would die. Right here right now. These were his thoughts as he charged up a yellow energy blast from his mouth, with all of his left power infused within it.

Acnologia raised a brow at the dragons actions, thinking him to be extremely foolish to even attempt to rebel against him, especially in his current state.

He just stood there waiting as he watched the blast charged and fired right at him.

"NOW DIIIEEE!!!!!!" screamed Palzrinth firing all his power towards Acnologia

Acnologia did nothing as he watched the blast approach and then engulf him within a blinding white light. Thinking, hoping even, Palzrinth allowed a smirk of satisfaction cross his face as he truly believed he bested the bringer of the Apocalypse. For only all of these thoughts to vanish as he froze in shock and horror when he heard the sound of slurping, and a maniacal laugh from within the explosion of power.

"DID YOU TRULY THINK THAT WAS ENOUGH TO BEST ME!!!!!!!!!!" Acnologia shouted in triumph of the scared lizard in front of him, swallowing all the energy shot at him that was meant to deliver him to the after life, but now only his meal. "NOW TELL ME WHERE ARE THE LAST THREE DRAGON KINGS!!!!!!"

"I-I-I-I D-DONT K-K-K-KNOW!!!!" Palzrinth screamed back in a mix of anger, frustration, but most of all fear

When the white light of energy disappeared down the bottomless pit of the Dragon kings belly, he looked up with a stern and stoic face.

"Very well, then you are of no use to me" Acnologia stated as he punched a hole into the poor creatures head, ending its life in a near instant, and began walking away in no particular direction only following his nose, for any possible surviving Dragons

"642 fallen today, which means I am another step closer to their complete eradication" stated Acnologia to no one in particular but himself as he walked of towards the rest of the dragon bodies. "I will bathe in all there blood, and my vengeance will finally be complete"


400 years later...

Britannia.

The home to many different species of creature, ranging from the Fairies in their magical forest, Giants in their battle loving tribes, and thd Humans divided in their own villages and towns, all living separately from one another living life the way they see fit. However, these are not the only races seen in this land.

Created by the Demon King, we have the Demon clan one of the two strongest of all five of the main races. And created by the Supreme Deity we have the Goddess clan, another one of the two strongest of the five races.

However, these two races are not native to the land of Brittania, each inhabiting there own realm, but this doesn't stop them from entering this country. Both trapped in their constant bitter rivalry between eachother. Both disliking eachother due to the hate between their creators the Demon King and the Supreme Deity. Both races trying to out power one another, caught in a constant stalemate.

And with these facts in mind we can move onto the story where we find a skirmish going on between these two powerful races.

2 members of The Ten Commandments, the Demon Kings most elite warriors, were currently trying to overpower a dragon to interrogate, one with dark purple scales, large bird like wings on a wyrm like body.

Now what does this purple dragon have to do with the Goddess race, you might ask, well the answer is simple the Dragons have been seeking refuge within the Goddess race from an enemy that none but the Dragons themselves believe really exists.

But if the races and in this instance in particular, Goddess race dont believe in the rumours and superstition surrounding the mysterious destruction of one of Brittanias strongest species, why would they take them in?

Power.

It is as simple as that, adding what small amount of Dragons there are left to their ranks, they believe they may give them an edge in their constant competition with the Demon race for superiority over the other.

However, an issue with this fact is the majority of the dragons that did survive the extinction of the rest, are either weaker than other Dragons so retreated before facing their greatest fear, or their arrogant enough to believe that rallying themselves with another powerful race, can help them grow stronger to destroy the monster, of who's name they hate to even mention.

The Commandments currently locked in battle with this beast were Monspeet the Commandment of Reticence, and Derieri the Commandment of Purity.

While the other Commandments hunted in different areas of the country for the now rarely seen Dragon race

The reason the Commandments were all sent out in small separate groups in the first place was to first confirm this rumour and second try and get the chance to interrogate a Dragon, to find out the full story to confirm the truth. The reason for this is try and gain another ally in this alleged monster that destroyed nearly all the Dragons, leaving none but a few stragglers.

And with that, let's move onto the battle taking place

"I really must ask you once more, please would you stop resisting and just answer are questions if you please" said Monspeet in an attempt to reason with the Dragon

"And why should I allow that? Hmm?, You Demons always have annoyed me, always thinking your above the other races because of your alleged 'superior' power" remarked the purple Wyrm smugly, and irratatedly

Derieri took this chance to remark with her own statement "The same can be said for you Dragons" she said nonchalantly, with the same bored and neutral face she had started with at the beginning of the battle

"Humph!, You dare compare a Demon to a Dragon!!" he shouted angrily at her, with his long tail smashing into the ground from behind him

"Now, now, we meant know offense, we only wish for a few questions to be answered so please just surrender quietly" said Monspeet getting ready mentally to fight the rest of the battle, as he knew the pride of a Dragon would never allow it to do such a thing

The Dragon took offense to the what the man said and decided to leap at him hoping to try and grab him within his sharp jaws, instead only to receive a punch from the female Demon from before that didnt hurt at first but as the punches and her counting continued he soon realised the punches kept getting harder and harder.

Using his head to think quickly he used his tail whipping her away as she just said "72" in her counting of punches, using enough force to throw her through a groove of trees smashing through 11 trunks winding her in the process, before he smirked internally and turned around to face the gentlemanly Demon who had now shot a flaming Phoenix at his side that burned right down to the bone, causing him to screech in pain.

Getting angrier and deciding to use more of its magical based power rather than its physical to slash at Monspeet with a Poison Dragon Claw attack, while not as strong as the now deceased Poison Dragon King, was still enough to throw him back in the opposite direction of where he whipped away Derieri.

Hoping this chance gave him enough time he turned around in an attempt to fly away from the opponents he assumed was defeated, only to then receive another flurry of punches from the once winded Derieri who now bore a scowl. This time however instead of getting knocked back like before she reached the number "100" which caused the dragon to topple over, gasping in pain from the punches that kept getting harder with each swing.

Hoping it would be enough of his painful torment slowly getting up he shouted " YOU WILL NOT BEST MEE, I AM A POISON DRAGON NOW DIIIEEEE!!!!!!!!, POISON DRAGON...ROOOOOOOAAAAARRRRR!!!!!!!" he roared right at Derieri who narrowly avoided the attacke receiving nothing but a graze upon her left shoulder

However; it stopped abruptly when she saw the shocked and pained look on the face of the scaled monster; and then saw Monspeet with his arm wedged into the side of the Dragon. Effectively ending the battle as it finally collapsed onto the ground while spitting out a light purple coloured substance from its mouth; which she assumed was the creatures blood.

The Dragon was breathing heavily knowing it had lost the battle against these powerful Demons, he looked up only to see them looking down upon him, he would have laughed if the pain wasnt to great, at the fact that he, a Dragon thought to be Brittanias most powerful species bested by a couple of Demons he hadn't even got the pleasure of learning their names.

These thoughts ceased as the moustached one decided to ask his questions still, and deciding that because they bested him in battle he would humour them in his last final moments before death, in his own way of acknowledging their strength.

"So, will you answer what we came to learn?" asked Monspeet

"Very... well.. *cough*..well done...on defeating me... both of you...now ask away" he replied in an almost respectful way

"To say from the ass, we wanna know why Dragons would side with the Goddess scum?" stated Derieri using her signature phrase

"Why...he he" he chuckled "We needed to retreat"

Raising a brow Monspeet decided to ask the obvious question "Retreat from what?, surely the Dragons wouldn't have been scared of an ordinary creature"

"Scared?" the purple lizard asked "We weren't scared... we were terrified... of him..."

"And who the hell is 'him' ?" asked Derieri in a slightly annoyed tone

"If I were to live I wouldn't even dare speak his name... a creature so powerful, so dangerous that even the Dragons couldnt defeat him, there are only three of my kind left apart from I, because of him..." the Dragon said in a mix of anger and sadness " But I'm going to die anyway so I'll give you the name of this vile creature... his name is Acnologia, the Arcane Black Dragon, Bringer of the Apocalypse, and the Devourer of Magic... if you ever cross his path I pity you, I pity you all" the Dragon said with its last dying breath

"Hmm, come on we should report this to Lord Meliodas at once" stated Monspeet, clearly in thought thinking about what the beast had said before dying

" Yeah, okay but do you wanna take a tooth so you can show of to my sister that we killed a Dragon" said a smirking Derieri, smirking in pride over the killing of a being as powerful as a Dragon, and teasingly as she saw the look on Monpeets face the minute her sister was mentione

She knew the both of them felt something towards one another, so found it fun to tease the both of them whenever she got the chance.

"Moving on, what do you think of this news?" said a slightly irritated, yet amused Monspeet

"I dont know, it sounds kinda ridiculous, how a single being destroyed all but three of the dragons" she replied in a dismissive tone

"Hmm, perhaps your right, anyway let's tell Lord Meliodas the news" Monspeet said as they both continued to walk away from the dragon corpse


AN: So there we go, i don't know how i did, but I would be incredibly greatful if you all let me know. So thank you all and have a good day. Bye
