"Nothing lasts forever, even stars burn out…"

That statement was a truth that no one could deny, Hadrian Legion knew it. Empires rise and fall, leaders are born and killed and an endless cycle of destruction that never ends. If Hadrian could name any fictional empire that reminded him of this statement, it would be the Sith Empire.

It rose and fell, adapted and conquered before falling again. He looked up from desk, his eyes glowing before fading in the candle lit room. He had been reading his Fathers (Legion, the one that was in the Bible) journal entries before his birth. His Father wrote that sentence after he wrote this…

The Great War is coming to a swift close, but my mind may never be the same again. I have battled every single one of my personalities and come to the conclusion that I may be dying from them. My only child is still growing in my wife's womb, I may live long enough to see him or her but I can't tell at this time. Nothing lasts forever, even stars burn out…

He closed the journal softly; his Father had fought his mind during the Great War while he had been still inside his mother. He sighed as he got up and walked towards the door, flicking his hand that sent a wave of air throughout the room, snuffing out the candles.

Hadrian Legion didn't have multiple personalities though, unlike his Father, Hadrian had multiple powers. He had his family's power of instantaneous possession, but he also had so many other powers that it was unbelievable. His family wasn't named Legion for nothing, it practically meant many or great in number.

He wasn't a fool in thinking he was a god, he wasn't and would never be. He may have power but power always comes at a price. His Fathers price was his sanity and death, Hadrian didn't know what his was but he knew that he had one. But now he had people that could teach him how to use hereditary powers such as the Power of Destruction that the House of Gremory wielded.

He had to practice with the power call Primal Abyss by himself however; no one had this power ever since the line of Lucifer had died out. He wielded all of the Inner Circle and Pillar houses powers but that was only a small portion in the wealth of power he truly wielded or chose to wield in any case.

He left his house and walked down the sidewalk, his peerage was all sleeping as it was eleven at night. Orochi was also sleeping in his gear, the eight headed dragon of the cosmos rarely spoke in Hadrian's mind as it wasn't nessicary in any way. The son of Legion found himself nearing the old school building, the aura of the Gremory's power was powerful the closer he got to the old building.

That was until he felt a shift in power, one of fire and healing. Hadrian transported himself, without a transportation circle, into the old building and found Riser Phenex standing there.

"You still think you will get Rias, don't you?" Hadrian snarled, his eyes glowing with power.

"You won't stop me; you are not the son of Legion! Riser thinks you are an imposter and liar, wanting Rias Gremory all for himself!" The boy spat, fire erupting into life.

"Want to bet on that, bird boy?"

"You are nothing to my flames! I can take you any day!" He shot back.

"Then let's fight, under the eyes of every single devil in the Underworld." Hadrian folded his arms, watching the devil.

"Yes, let's do it right now." Riser smirked before vanishing, probably to get the leaders of the Devils.

Hadrian followed his power and transported himself next to the Phenex, raising his eyebrow as he saw the four Maou's. Truth be told, the Inner Circle houses of Devils were the four Maou and Legion, as they were the original angels that had fought against God and were cast out. But the families of the Inner Circle had all but died out, Hadrian was the only one left of the Inner Circle now.

"You want to fight Hadrian Legion, right now?" The crimson haired devil, Hadrian knew this to be Sirzech Lucifer.

Riser nodded "Indeed I do."

Hadrian spoke up "He entered the ORC with ill intent so I stopped him, leading to this to prove that he can't have what he wants. Wake up the Underworld and have our fight view from every household and street, Legion vs Phenex."

"We will have the pocket dimension ready within the next thirty minutes, everything else in ten." The Leviathan Devil said curtly, Hadrian noticed the bags under her eyes.

"Get out, Inner Circle business, Phenex." Hadrian barked, making the boy jump and vanish in a flash of fire.

Hadrian pointed at the Leviathan devil "How many night have you gotten sleep?"

She looked thoughtful before sighing "Only three out of a full month, I think…"

He looked at the others, only one looked well rested and that was Sirzech. Hadrian sighed, pinching the bridge of his nose before he spoke.

"I think I know why my Father didn't want to lead, this is what it leads to. After this fight is over, all of your get some sleep and don't come back to leading until you are fully rested."

Sirzech smiled sadly before he said "We can't do that you know…"

Hadrian stopped him right there "I am Hadrian Legion, you are Lucifer in-name only! Sirzech Lucifer nee Gremory, you may have power but you do not have the blood to call yourself one of the Inner Circle. I am the only remaining Inner Circle member left; you all are in-names only. You may have forgotten that Inner Circle members can remove you from your position."

"Now, can we get to the fight, I avoid pointless squabbles but if a fight is going to happen then I will end it." He said before walking out of the chamber to wait.

Hadrian looked at Riser with disgust; the devil only wanted Rias for her looks and power. It was true that the 72 Pillars were dying but that was rectified through the evil piece system, all the Devils had to do was adopt the reincarnated devils into their house. But traditionalists of the Old families still lived and would fight against it.

The Old Purist families would want Hadrian to marry one of the Pillars or the Leviathan leader to continue the bloodline, Hadrian would rather hang himself then do that as Tia had many ways of killing before he died if that did happen.

"You ready to burn, liar?" Riser snarled, his wings burning at full power.

Hadrian leaped into the air and let his wings unfurl, all twenty of his Demon Vampiric Devil class wings. Devil's had three wing classes, normal class, Vampire class and then Hadrian's. Vampire class wings looked more bat-like and could suck the blood from a fallen enemy, Demon Vampiric Devil class wings were huge dragon like wings, hellfire burned in between each of the wings fingers, which were tipped with venomous spikes.

Most of the Devil had normal class wings, Vampire class wings had only appeared when the original 72 pillars formed as the head of each house had them. Inner Circle houses were the only Devils to have the final wing class, Lucifer's original angel wings had morphed into them when he made himself a Devil and showed his generals how to become Devil's as well.

Lucifer had 30 wings, his generals had 28 wings, Hadrian had 20 wings and Devils never got pass 14 wings as the more wings you have, the more powerful you are. If Hadrian hadn't been the son of Legion, like Riser said he was, then he wouldn't have these wings.

"You ready to suffer?"

Riser started throwing Phenex fire at him, Hadrian simply countered with his own Phoenix fire. This made Riser get angrier and fly at him, fists covered in fire.

"You are nothing to me!" He shouted, trying to punch Hadrian.

Hadrian said nothing, dodging easily as the unfocused attacks came at him. Hadrian knew that Riser would never tire because of his family's powers, but he would need a breather as his brain and body needed oxygen to work. When the boy started wheezing, Hadrian struck hard and fast.

His training with the Goblins showed itself, each strike hit a pressure point with accurate precision. He finally brought his knee into the devil's gut and shoved him away; Riser crashed into the ground but was getting up slowly, wincing at every movement. Hadrian decided to end this by summoning two of the most powerful Devil powers to each hand.

The Power of Destruction grew in his left and Primal Abyss sucked in the surrounding matter in his right.

Riser finally looked terrified.

"Who are you?"

Hadrian glared at the Phenex before answering with a verse from the Bible.

"My name is Legion: for we are many."

Hadrian sent both of the energy balls at Riser, who screamed as they connect. Hadrian knew that Riser would live but wouldn't be left unmarked. Primal abyss and the Power of Destruction would leave mental and physical scaring and not even Phenex healing could heal it. Hadrian cut the flow of power that he was fueling to the destructive powers, watching as they sputtered out and vanished, leaving behind a blood and beaten Phenex.

The son of Legion landed on the ground, his wings disappearing as he walked towards his fallen foe. Riser was out cold, his flames slowly crawling over his body to heal him. Hadrian sighed before waving his hands over the fallen devil, making him vanish from the battlefield and into a hospital bed. He summoned a teleportation circle for himself, glancing around the disintegrating arena before stepping into it and vanishing.

Hadrian returned to the human world and was promptly grabbed by Tia into a fierce hug. The queen of the serpents must have seen the entire fight, as she had tears in her eyes. Hadrian hugged back as best he could and then noticed who else was around. Rias and her peerage and his own were both looking at him in aw, his peerage was less aw and more that they knew that their [King] was still alive.

Tia finally broke the hug and said "You had me so worried, Harry!"

He pulled her against his chest, one hand holding her head as he whispered "I should of warned you, but by the time it had happened it was too late, Tia. Riser, however, was going to do something to Rias and I had to stop it."

Issei spoke up "Wait, that punk was here?!"

Hadrian nodded towards the Dragon Emperor, "Yes, but I handled it before anything could come of it."

It would be weeks later that Hadrian and the Church meet for the first time, he had been to church before but that hadn't been the same church apparently. It was just him and Tia at the ORC, talking to Rias about the representatives that the Church had sent, when someone knocked on the door.

"Enter" Rias called, the door opened to show…two young women in white cloaks and skin tight black body suits.

"Greetings!" The first said, she had orange hair that was tied up into twin tails, her cloak revealed her shoulder that had a single string tied to it. "I'm Irina and this is my partner, Xenovia."

Rias smiled before motioning for the two to the empty armchairs, then introduced herself "I am Rias Gremory, this is my [Queen] Akeno and my [Pawn], Issei."

Hadrian noticed that Issei and Irina glance at each other before looking away. That intrigued him but he refocused himself as he notices Irina look at him.

"So, what is your name?" She asked.

Hadrian answered with his own question "Tell me what does Mark chapter 5, verse 9 says"

Irina paused before answering "And he asked him, What is thy name?"

Hadrian finished for her "And he answered, saying, My name is Legion: for we are many."

That sentence shocked the two women; Hadrian looked at Tia before continuing "This is my [Queen], Tiamat."

The blue haired woman, Xenovia, asked flatly "You only gave us your last name, what is your first?"

Hadrian answered in the same flat tone "It's Hadrian, Hadrian Legion"

Rias quickly interfered "I believe that you two came here for something, yes?"

Irina nodded "Yes, the Church sent us to find the stolen Excalibur fragments and get them back."
