Okay so this is too support the new Natsu is E.N.D theory! It won't effect my other stories of Fairy Tail so don't fret! Just a heads up Natsu disappears after the battle of the dragons so isn't present during the Sun Village Arc. Furthermore there will be more demons added. Finally I might be moving a little bit slower since I'm preparing for college in the Fall but I will try and do what I can. Anyway without further ado let's begin!

(Somewhere in Fiore)

High above in the sky, far from the eyes of humans, animals and any other creatures, was a giant piece of earth in the shape of a cube, floating aimlessly in the sky. At the top part of the cube, which looked like a barren wasteland, was a giant and slightly ruined castle. It had three separate sections, one on top of the other with the first two squarer in shape while the third and top one along with the turrets and roof are more curved. Surrounding it and protruding from the ground are number of spines with spikes on them. All in all it had a very demonic appearance and it was well suited since it served as the home and headquarters of Tartarus, one of the three major Dark Guilds and a third of the Balam Alliance.

Currently there was a lot of commotion going on within the castle as various sections were covered in ice, with people trapped inside them too. Voices could be heard as more people, all of them wearing matching attires, were running about. All of them were heavily armed. "What's going on?" A commanding yet calm female voice shouted to some of the soldiers.

"Rosa-sama! Silver-sama has gone mad! He's freezing everything in his path and appears to be trying to make an escape!" A soldier replied to the woman.

Said woman had a voluptuous body, including pure white skin, large breast, perfectly shaped thighs and hourglass figure. She had long purple hair that went down to the center of her back completely revealing her face with bangs on the sides on the side of her face. Sticking out of her hair were ears that had pointed tips and each one had two earrings in them. She had pink eyes and slit pupils similar to that of a cat. Her outfit consisted of a black dress with long sleeves that fell down just below her knees with a high thigh slit on the left and a golden chain belt wrapped loosely around the waist of the dress. The dress only covered the upper parts of her arms and the underside of her breast, leaving the top and shoulders exposed. Under her dress she wore long blue leggings and black shoes. Just beneath her left knee was a violet variation of her guild's symbol.

The woman made a "tch" noise at the news before looking at the soldier. "Tell the others not to engage Silver. They would be no matched against his magic. I will go and deal with him." Rosa said before turning towards another soldier. "Can we pinpoint Silver's current location?" She asked.

Before the soldier could reply the sound of a twisted laughter rang through the halls. Coming out of the shadows was another unusual person. This person was male by the looks of it and had a short and round yellow body with purple markings. He wore armor that covered his shoulders and arms plus a helmet that covered the top part of his head only as well as his sole eye. He also had no ears either but instead three holes on the sides of his head in their place. Around his neck was a necklace as well as other various paintings while black stripes were around his arms and legs. To top it all off he had a cane in his right hand, most likely using it to balance himself. The cane had a round top with the guild symbol painted on it. "Gehehe, I'm afraid that won't be possible Rosa-sama. Silver-sama has already left the castle and teleported down towards the surface. Though he might be off from his selected trajectory due to a brief scuffle he had with Abaddon-sama." The round person exclaimed, never losing his gleeful smile.

"It would've been a lot better if I had stopped him altogether, Franmalth." A third voice said that caused Rosa and Franmalth, along with the Tartarus soldiers swiftly turning towards the source. Another person, a male again, moved towards them. He was a tall man with a lean muscular build. His skin was a dark orange with red swirl markings covering his entire body. His hair was short, spiky and grey while sticking out from his forehead was a small pair of light yellow horns. He also had a short grey beard too. His eyes were a dark red that seemed to glow fiercely. He wore dark grey armor that consisted of a chest plate and greaves, with golden gauntlets. Strapped to his shoulder pads was a dark red cloak that went down to his ankles. Underneath his armor he wore a short sleeve black shirt, and white trousers. On his feet were black sandals that revealed only his toes. The last bit was that on his chest plate and greaves were a yellow version of his Guild's symbol, while a black variant were on his gauntlets.

"My apologies Abaddon-sama." Franmalth said politely, showing a great level of respect for the newcomer.

Abaddon paid him little attention as he kept talking. "Silver's actions are due to learning that our Master's has returned. He most likely fled knowing that he couldn't take on all of the Demon Lords before reaching the Master." Abaddon explained.

"So he has gone to gain allies then? Gehehehe" Franmalth summarized. "But who would be foolish enough to challenge us anyway?" He asked rhetorically.

"Abaddon-sama, should we dispatch forces to hunt Silver and eliminate him? His magic is a serious threat to the Master." Rosa asked the leader of Tartarus's elites.

"No" Abaddon said plainly, showing his fangs. This caused Rosa and Franmalth to look at him in surprise. Turning towards the soldiers gathered Abaddon said, "Go and remove the ice and recover the wounded. Also have sentry position over the Cube in case of attacks. And keep an eye out for Silver and inform me once you found him." The soldiers nodded before heading off. Abaddon then turned towards his fellow Demon Lords. "We've been give orders by the Master to await further instructions. Or are you challenging his orders Rosa?" Abaddon said.

Rosa looked like she wanted to argue but knew that it would be pointless to speak against the word of the Master, not that she ever would. Letting out a sigh she said, "Very well then I shall not act." She replied with a bow before walking off, leaving the two males to themselves.

Elsewhere in a different section of a castle, two people could be seen in what appeared to be a throne room, with torches ignited with blue flames that illuminated the room. Banners hung from the ceiling with robust color and yellow trims on the side and the guild's symbol printed in large black ink. At the far end of this intimidating room was a throne. The throne was dark red in design with armrests that had demon faces at the front and black cushions on the seat and backrest. It stood on top of a small podium that had a black rug going down from it towards the large door entrance on the other end.

One of the two people was standing before the other. This person was a young man and appeared to be human were it not for the demonic gleam in his eyes. He had long shaggy dark colored hair, with the bangs reaching his nose and some strands covering the sides of his face all the way below his shoulders. On the back he had his hair form into a big ponytail. The attire he wore consisted of a long black jacket trimmed with a light-colored flame pattern with the lapels being a matching color too and tattered at the bottom of the jacket. Under that was a black frilly V-neck shirt, closing down the middle with a belt at the clavicle. The ending was a pair of light-colored pants that laid over a pair of with a seam down the middle a a pair of black buckles, two on each calf crossing over one another as an X. This man was Mard Geer, also known as the Underworld King and second-in-command of the Dark Guild Tartarus.

The second person was sitting on the throne that Mard Geer was facing. This one also looked like a young man, but his clothing and the darkness hid most of his form. From what could be seen was that he had tan skin, and lean muscles too. He wore an open-collared, long-sleeve red coat with golden trims with a matching cloth held by a brown belt with an oval golden buckle. Underneath the coat was a short sleeve black muscle shirt. For the lower part he wore black trousers also held by the belt with matching black trench boots covering his feet and nearly reached his knees. The boots were held by three grey bands each and had yellow lines at the bottom of the boots. And finally, the man wore a tattered, black, ankle-length, hooded cloak, with said hood over his head and covering his face. The man seemed to be calm judging by his posture, which was his right elbow resting on the armchair while he rested his chin on his right fist.

"So Silver fled." The hooded man said, not asked.

"Yes, it appears that he realized that his chances of reaching you without fighting the Hell Gates currently here would be pointless and decided to retreat." Mard said with a calm expression on his face. "What are your orders regarding this Master?" The man asked.

The hooded man smirked, fangs glinting in the dark. "Why would you ask a question that you already know the answer too Mard?" The man asked jokingly.

Mard merely smirked in response before bowing his head respectfully to the Guild Master. "We'll proceed as usual and when the time comes we'll deal with that remnant of a human. But in the meanwhile summon the Demon Lords that are not on an assignment. That excludes Jackal, Broma, and Tempesta." The man said.

"And what of Kyouka?" Mard asked.

"She has gone off to find suitable recruits correct?" The man asked, receiving a nod from the Underworld King. "Then leave her be. She will be finished soon."

Mard Geer bowed. "As you wish Master E.N.D" The Underworld King before walking out the room, leaving E.N.D, the Black Mage Zeref's most vile creation, alone to his musings. Within the dark chamber, with only blue flames as a source of light, the hooded man said to himself. "Now then will the darkness of hell consume the world in one fell swoop? Or will the light put up a fight before overrun by despair?"

(Era, Magic Council)

Outside the building that housed the Magic Council, several guards patrolling the outer walls were talking amongst themselves.

"Hey did you see how Fairy Tail did during the Grand Magic Games?" One of the guards asked two others while the fourth was several feet away.

"Yeah, turns out their core members returned after seven years of being missing. It was because of them that they got back to the top." A second guard added.

"And did you see how sexy their women were during that match against Mirajane and Jenny?" A third guard said with a faint blush on his face.

"Hell yeah those Fairy chicks look like they haven't aged a day!" The first guard replied with a laugh.

"Hey George why don't you join us?" The second guard shouted towards the fourth guard. But all he got was silence. "George…?"

When there was no response the second time all three guards turned to see that their fourth companion was missing, completely vanish. "H-hey where did George go?" The third guard asked nervously, raising his spear.

"I, I don't know. He was here a moment ago." The first guard said.

A brief changing in the wind caught their attention and as they turned towards the second guard they saw, much to their horror that he too had vanished without a trace.

"What the hell!?" The first guard exclaimed only to be greeted with silence for the third guard had also disappeared, leaving the man all by himself. The man didn't even have a moment to yell out before darkness consumed his vision.

Meanwhile inside, things were progressing normally as ever. Today the council was in session with a very important topic at hand. Though somewhere along the line it shifted towards the thoughts of a certain magic guild. "Fairy Tail won the Grand Magic Games, eh." One of council members commented.

"Oh boy" One near him said. Outside the room were Lahar and Doranbolt who couldn't help but listen in. Doranbolt resisted the urge to snort and merely rolled his eyes while Lahar smirked at his colleague.

"The moment that the Tenrou Group came back, this is what they give us. Seems like that guild enjoys stand out." Another member said.

"Yes however have you heard that one of their dragon slayers, the one called Salamander, disappeared after the games?" The first member said.

Doranbolt winced when he heard that comment. During the final stages of the battle with the seven dragons and future Rogue, it was Natsu Dragneel, Fire Dragon Slayer of Fairy Tail whom had save the day and in result the entire country. He had managed to send himself, future Rogue and two dragons, one of them that had joined Natsu's side, smashing right into the Eclipse Gate, the source of where Future Rogue and the dragons came from. However he had disappeared after the result of the explosion, nothing but his scarf could be found amongst the ruins. It had been a wound that Doranbolt knew that Fairy Tail would not recover from so easily.

"I'm still more focus on if we should even still keep hosting the Grand Magic Games or not." A fourth council member said.

"Well if an entire kingdom supports it then there is little we can do to stop it. Just trying to step in and dictate such matters is hard enough." A fifth council member replied.

"Silence everyone!" Chairman Gran Doma said to the council staff banging down onto the ground. Once eyes were on him did he continue to speak, "We did not come here to discuss about such things, today's topic is Tartarus. At first they had barely done anything to acquire our attention but until seven years ago they had slowly become more active. And since seven days ago dark guilds affiliated with them have been wiped out. As we haven't been able to identify those responsible, this is both a thankful and trouble situation."

"If it's the work of an official guild, there is worry about a possible retaliation." A counselor commented.

"What about that independent guild?" Another asked.

"Crime Sorciere!? Hm, that is a definite possibility." Another one said.

"This reeks of Fairy Tail if you ask me." A female counselor said.

"Perhaps with great power, comes a desire to show it off." A counselor added.

"I think it's a bit unfair to judge Fairy Tail so quickly." Org said after hearing these comments.

"Org-roshi always tends to take Fairy Tail's side in such matters." A counselor chuckled.

Ignoring the comment Org continued. "This is just a hypothesis, but what if the perpetrators were Tartarus themselves?" Org wondered out loud.

This seemed to attract the council's attention, with some looking a bit skeptical. "Why would they do such a thing?" A counselor asked.

"Who knows" Org replied "However, there are grounds to believe it could be to strengthen their forces while simultaneously cutting off superfluous weeds." Org explained.

There was a moment of silence as the council members looked at one another. Before long they all burst out laughing, saved Doma and Org, the latter shocked by the laughter.

"Dark guilds taking each other out!?"

"That's impossible"

"Tartarus already has all the forces they need."

"Org-roshi, maybe you're getting senile in your old age?"

"Well, Org-roshi's theory is a plausible one." Gran Doma muttered cutting off all other voices.

"Chairman!"

"Now is the time for us to deal with Tartarus after turning a blind eye on them for so long." Doma's face took on a serious expression as he spoke. "The true form and might of our enemy remains unknown. But if they were to fall apart here, the Balam Alliance would surely follow. Now is the time in which, we as the council must take up our strongest arms and make our stand."

Suddenly the council doors burst open, with a terrified guard coming in. "I-it's terrible!" The guard shouted in hysteria.

"What!? Fool! We're in the middle of a meeting here!" A counselor shouted.

"N-Now's not the time for that! Intruders have-" The guard was cut off when explosions went off everywhere in the building. Walls fell down, flames seared through, ripping through pillars and tearing through the guards and other occupants. By the time the explosions died down the once grand building was nothing more then a pile of rubble with smoke rising into the sky.

Amongst the rubble in the destroyed council room, Doranbolt pushed himself up. Coughing and clutching his head the man looked around in horror at the destruction. "W-what happened?" He murmured before his eyes widened as he saw Lahar lying on the ground motionless. Rushing over Doranbolt picked up his friend. "Lahar! Hang in there! Answer me!" Doranbolt said. He gritted his teeth when he felt no pulse from Lahar. "This can't be…" He said as he looked around and saw all of the counselors dead, even the chairman. "No way! Is anyone still alive!?" Doranbolt pleaded.

"D-Doranbolt…" A weak voice said.

"Org-roshi!" Doranbolt exclaimed, as he was about to run towards the injured counselor. But before he could move a hand suddenly appeared and slammed on top of Org's head. On top of the counselor was a young muscular man with multiple animal features. His light hair reached down to his shoulders while covering the left side of his face, also jut upwards on top of his head in a pair of prominent protrusions shaped like ears (though they did look actually ears however), his nose was small and dark like a canine's; he had a furry tail protruding from his lower back and pointed teeth. His eyes had dark slit pupils and bear a thick dark outline and dark spots were presented around them. His forearms and hands were almost completely covered by a larger variety of similar covered shapes, which in correspondence to his wrists fuse together to leave his hands completely dark. His attire was a light, striped tank top on his torso, pair with a dark bandana that adorned by light spots circling his neck, which was arranged to form three ends pointing downwards as well as some sort of collar. A light garb was around his waist and held closed by a button on the front of its belt-like part and split in two tails on the back, each adorned by a series of dark rectangles near their lower edges. Finally his pants were very loose and baggy and while mainly light in color, they also had dark sections on the thighs' front and on the calves' back with a clasp-like ornament located some inches below each knee.

The man snickered as he held Org's head. "No, no, letting you live is not an option. Assassinating all the council members is our objective after all. Explode." The man said.

"O-Org-roshi!" Doranbolt cried as he tried to help the counselor. However he wouldn't be able to reach him in time. "Stop!"

"Doranbolt run…" Org ordered.

"I-I cannot!" Doranbolt shouted.

"Think of what would happen if we lose you?" Org said seriously.

"Running is not an option. Not from my explosions anyway." The assailant commented.

"Go Doranbolt!" Org ordered again as Jackal's hand began to glow energy.

"The name is Wild Dog Jackal, one of the Demon Lords of Tartarus. Remember that in hell, as the name of the man that massacred the entire Council!" Jackal declared.

"Live! Live to carry out your own sense of justice…Doranbolt!" Org cried out.

"Org-roshi!" Doranbolt shouted as the entire area was engulf in flames.

Several seconds later, Jackal could be seen standing at the edge of a cliff overlooking the ruins of the Magical Council. He appeared to be taken in the sight when a voice suddenly spoke from behind. "As ever Jackal you do things so flashy like." The voice said.

Jackal turned around to see a person appearing out of thin air. The person was standing oddly, his knees bent as he walked towards Jackal, his back hunched. He had pale white skin and long wild green hair that went down past his shoulders. He had dark green eyes with the sclera being black. A dark purple cloth covered the lower portion of his face, completely obscuring his mouth. His arms and legs were lean and muscular and his nails were colored red. The person wore a long-sleeve purple poncho, with the sleeves going past his hands. The sleeves had purple and yellow stripes. A golden necklace was hanging around his neck with a straw raincoat protruding from the back of it. He also wore black trench pants that reach his knees and no footwear, however, and he was completely barefoot. On his right calf was the Tartarus guild symbol, with another one on the mouth cloth.

"Heh I was just getting the message across Broma." Jackal retorted.

Broma chuckled through the cloth. "Heh, heh, that and subtle was never your forte, Jackal. Remember if I hadn't gotten rid of the guards outside, you'd never would've gotten in." Broma commented.

"Tch" Was all Jackal said before he began walking off. "Oh by the way." Broma said as Jackal walked past him. "We've been given new orders. You're to head towards the next target and I'm to return back to base. And it seems as if Silver has betrayed us." Broma reported.

"Did he now? That probably didn't go so well." Jackal commented. "So what did the Master say to that?"

"For now we leave Silver be until he's next spotted." Broma reported before he began shimmering. "For now our orders are simple…raise hell." And with that Broma vanished into thin air.

Jackal stood there for a few seconds in silence before cackling gleefully. "Ah it's good to have the Master back!" He said before heading off.

(Magnolia, Fairy Tail)

Meanwhile things at Fairy Tail were going along their normal pace, people laughing, drinking and the occasional fighting. However right now Erza, also known as Titania and an S-class mage of Fairy Tail, was conversing with Guild Master Makarov about recent events at the Sun Village.

"So that Minerva joined a Dark Guild?" Makarov asked.

"Yes and it seemed as if though she knew or had information about who was responsible for turning the giant's village into ice." Erza replied as she recalled the spirit of the flame dragon, Atlas Flame, saying it was the work of an Ice Devil Slayer.

"And what of her father? The former Guild Master of Sabertooth?" Makarov asked.

"His whereabouts are still unknown." Erza said.

"Hey speaking of Sabertooth, I heard that Sting is the new Guild Master!" Laki commented to the side.

"Wow, a young and good looking guild master?" Kinana wondered, unknowingly causing a twitch from Makarov who overhead them.

"Either way we should report this to the council. Minerva was a powerful mage and her being part of a Dark Guild might cause problems." Makarov concluded.

"I was also thinking of contacting Sting as well." Erza replied.

Elsewhere not to far form where Juvia was trying to get Gray to eat what she called 'Juvia-bread' Lucy, Wendy, Gajeel, Happy, Carla and Pantherlily were gathered around Levy who had a book in her hand. They were researching a demon named E.N.D, one whom Atlas Flame had mentioned as the vilest of Zeref's demons and that Igneel couldn't kill it. A thing to notice was that wrapped around Lucy's neck was Natsu's signature scarf, wearing it as a memento of the deceased Dragon Slayer. The Celestial Mage had taken to wearing it after finding it amongst the remains of the Eclipse Gate that Natsu gave his life to destroy by sending Future Rogue and a dragon crashing on top of it. The scarf had been the only thing of the Fire Dragon Slayer's person that could be found since they couldn't even find Natsu's body.

"Here it is." Levy said. "E.N.D, it doesn't go into much detail about it. But it seems that it's on a completely different level as Deliora and Lullaby combine." The Script Mage said.

"Does that mean its Zeref's most strongest demon?" Lucy wondered.

"That would be really scary." Wendy muttered.

"What are these demons of Zeref's books anyway?" Pantherlily asked.

"The hell I'd know." Gajeel commented.

"There demons created by the Black Mage Zeref. All the magic needed to summon them is imbued into books he made." Carla answered.

"So if we had one of those books we could summon a demon?" Happy asked.

"I guess, though it's most likely one demon per book." Carla replied.

"And the one that has E.N.D. could possible in the possession of Tartarus." Lucy commented. "And according to Atlas Flame's spirit Natsu's dragon, Igneel, couldn't defeat it."

"Didn't you say that you saw Zeref on Tenrou Island?" Levy asked Happy.

"Aye, Natsu, Evergreen, Elfman and I ran into him during the S-Class Exams." Happy replied with a shiver, recalling the intense moment at that time. "And it looked like Zeref knew Natsu somehow"

Before anyone could think about that the guild's door bust open, revealing a frantic Droy and Jet, the former crashing onto the floor while the latter was shouting with a newspaper in his hand. "This is bad! Big news just came in!"

(Magic Council Prison)

"I thought it was about time you showed up." Cobra said as he stared up at a grim looking Doranbolt from his cell. Said man's clothes were tattered, especially the cape, and he had bruises and cut all over his body.

Doranbolt glared down at him. "I presume that you 'heard' everything that happened up there." He said.

"Don't be stupid, this cell seals my magic. I just heard the explosions." Cobra responded.

Getting straight to the point Doranbolt said next, "Spit out what you know about Tartarus."

Cobra smirked, "I an't squealing for free you know. I demand the release for all six of us in exchange."

"I don't have the authority to do that." Doranbolt replied in a monotone voice.

"Then speak about it to the higher ups." Cobra said with an indifferent shrug.

Doranbolt was quiet for a moment before replying. "The higher ups…are all dead."

Cobra's lone eye widened before he smiled. "Guess they really went all out there." He said.

That seemed to have set something off inside Doranbolt. Because for one moment he was facing in front of Cobra and the next he teleported right behind the dark mage, a dagger touching Cobra's neck. "My friends are dead, and my patience is wearing quickly. Speak now or you breathe your last breath." Doranbolt said in a calm but threatening tone.

Cobra seemed stunned for a brief moment but quickly recomposed himself and smiled. "I an't budging on that condition of mine. Those are my allies, regardless of circumstances. But, I will tell you one thing."

(Tartarus HQ)

Broma was standing on top of a ruined pillar knees crouched, outside the meeting room. He was minding his own business when a feminine voice spoke, "You seem to be in a good mood Broma." The voice said as a woman approached the man with several soldiers behind her. Said woman had unique appearance, mainly being her half-human half-aviary appearance. She also has a large chest and a curvaceous hourglass figure, both of which were emphasizes by her revealing attire along with a helmet that covered her entire face minus her eyes, mouth and two long wing like pieces of hair protrude from the side. She also had sharp and scaly talons hidden by long sleeves while having bird like feet.

"Well if it an't Kyouka-san. I see that sexy body of yours hasn't change at all." Broma said with a large grin. "Did ya hear the news?"

"Of Silver's betrayal?" Kyouka asked. "Yes I expected such a thing but it seems that a replacement has already been brought in."

"The Master is quick isn't he?" Broma asked. "I hear the new guy's a tough one."

Kyouka nodded absentmindedly. "By the way where are Tempesta and Jackal?" She asked.

"They're still on missions." Franmalth said as he approached the two. "Broma-san was recalled back in order to receive new assignment, as were the rest of us."

"That means that the operation has begun." Kyouka said with a smile as more people plus Abaddon and Rosa joined them. All of them had different appearances but all were menacing.

"Indeed" Abaddon said as he walked at the head of the group, the other's following. "Now is the time, for us to show the humans the power of the Underworld. The hell brought forth by the Demon Lords of Tartarus."

"None of them are human." Cobra said with a wide grin. "They're all demons from Zeref's books."

Doranbolt's eyes widened in horror and shock at the revelation. Cobra kept speaking however. "Their Master's name is E.N.D. The strongest demon out of Zeref's library of works."

So there you go! Just to let you know thirteen new demons have been added to Tartarus, hence why it was changed from Nine Demon Gates to Demon Lords. Also Silver's earlier defection I made since he wouldn't stay if E.N.D had fully recovered since he wouldn't be able to go against the other demons all at once. So another demon has already taken his position. Plus it adds some more drama too. Review!
