Prologue: There's No Going Back

A/N: Sorry guys, I know I haven't updated some of my stories in a while but I felt the need to write a PJO and Divergent crossover due to the severe lack of good ones on

One Fandom Is Not Enough≈


Summary: Nico accepts a dangerous quest from an ancient deity, even though Hades warns him that he may never be able to come back. The quest lands him in the future with the task of stopping the horrendous amount of deaths written by the Fates. Can Nico find Tobias and Tris before the events of the Divergent trilogy play out into the Fates' hands?

WARNINGS: I haven't really worked out fully what's in this story yet, but oh well, I predict that there will be deaths, swearing, injuries and probably a hell of a lot of weapons. No slash relationships planned…yet… OH, WAIT!

NICO DI ANGELO-

Nico lay on his bed in the relatively new Hades Cabin. The war with Gaea had taken much longer than expected. They had reached Athens to and fought hard to prevent her rise. They managed to interrupt the ceremony undertaken by the Giants to try and wake her with 'The Blood of Olympus', the blood of Olympian demigods. But unfortunately, they had already sacrificed the female demigod.

Annabeth.

The memories of her blood dripping down the mountain still haunted Nico. Sure he didn't fancy her, but she was one of the very few people Nico could even attempt at calling a friend.

Sure, he was jealous of her, but that didn't mean to say he didn't care about her.

He laughed bitterly, was this seriously how despicable he was? He had no reason at all to hate or even remotely dislike Annabeth, other than his selfish jealousy. Jealousy that he shouldn't even have.

He knew he could never have Percy. He never stood a chance, he had nothing on Annabeth. There was seriously nothing to actually dislike about her, she was perfect.

Everyone knew it.

He knew it.

Percy knew it.

After her death, Percy sort of broke. He was silent, completely. It was not so much that he refused to speak to anyone, more that her physically could not.

Days passed and Gaea grew stronger, she was now half awake, growing more and more aware of everything by the second.

Days turned into weeks and the demigods eventually pinpointed the place in Athens (predictable much?) where the stronghold of Gaea's forces were.

They launched an attack to weaken the army and it was on that attack that Percy did something that shocked everyone to the core.

It was impulsive, unpredictable and selfless with complete disregard for his own life. So basically, they should have know that he would pull a stunt like that, especially as Annabeth, who was the one who normally talked some sense into him, wasn't there.

Whilst the force that the demigod's had brought were locked in combat, Percy disappeared to the beach shore. He called upon Bessie.

Bessie the Ophiotaurus.

Bessie the Ophiotaurus who had been completely forgotten about but still held enough power to overthrow the Gods.

Percy sacrificed the Ophiotaurus, knowing full and well that the power that it would give him would surely burn his mortal body up very quickly.

He was right. But not before he returned to the fight stronger than Zeus himself and fought Gaea one on one.

The battle was ferocious and as Gaea dissolved with a blood curdling scream, filled with agony, Percy went with her.

The sacrifice had called upon the Ancient Gods themselves to give Percy strength in battle, it worked, but at the heavy cost of Percy's own death.

Nico had a feeling that Percy craved death anyway, without Annabeth he was incredible depressed, and pushed everyone away. It hurt to see him like that. After death, he would by reunited with Annabeth in Elysium, if not the Isle of Blest as they certainly deserved it.

Nico was left in the world of the living. Alone.

No one at camp particularly liked him, they were all scared of him and feared his father.

Nico clenched his fist, even now, the campers didn't really recognize Hades as an Olympian. He was one of the eldest Gods, one of The Big Three. He deserved respect. He deserved admiration.

But no, they all sneered at him and his freaky powers. They laughed at him and his abnormal abilities. They ignored. Just like almost everyone Nico could remember in his life.

It was humiliating.

And lonely. No one would talk to him, no one would spend time with him, no one would even try and approach him.

Piper and Leo stayed with the Romans at Camp Jupiter, none of whom had spoken to Nico since the Battle. It hurt, but he understood, they were scared of him. After Percy had died, Nico lost it. He wasn't completely sure what had happened, most of his memory was red hot anger, but Hades said that he had fully embraced his Underworld powers and took on the remnants of Gaea's army with the blessing of Hades.

He often stayed in the Underworld, he had grown closer with his father, but he was always busy. Persephone wasn't very friendly, but Demeter was okay. When she wasn't trying to shove cereal down your thought that was.

Hades had started to teach Nico how to properly use his powers, and was strengthening them. He had given Nico a bead to put on his necklace that would heat up if Hades wished to speak to him.

It started to heat up and Nico groaned, he had already shadow travelled today, to visit Sally and Paul Blofis, who liked to spoil him now that…now that Percy wasn't there any more.

He was bone tired, but nonetheless, he couldn't decline an invitation from a God, his father at that.

He stood before his father looking at him cautiously (they had got past the bow to me puny mortal I am a God and you do not deserve to stand up straight in my presence phase very quickly).

He looked extremely serious, which meant he either had very good news, very bad news or very worrying news (Hades didn't do happy so he was serious when delivering good news).

"Son. I have…there has been…an interesting development." rumbled Hades thoughtfully.

Nico blinked. What was Hades talking about? A development with what? Whatever it was, it was enough to make Hades look worried.

"You know how your dear cousin Perseus sacrificed the Ophiotaurus?" asked Hades.

Nico gritted his teeth, trying to cut out Percy's screams that he had let out when he died from burning up from the raw power in his body. His brain had thought that it would be a perfect time to replay them in his head. "Yes father."

"In doing that, he awakened the Ancient Gods, to give him power. One of them is still awake. They contacted my earlier today in a vision, I have been told that they want to speak to you."

"Me?" frowned Nico. "Why would they want to speak to me?"

Hades pursed his lips. "I am not entirely sure, but I have feeling that they may offer you a quest."

"A quest?" Nico's brow furrowed even further. Why would an Ancient God be willing to stay conscious just to give Nico of all people a stupid quest?

"Make no mistake Nico, they will not give you a quest for no reason, it must be very important."

Nico nodded, processing the news. "How will they speak to me?"

"Tonight, when you fall asleep, they will visit your dreams and talk to you about it. Should you accept then…well I am not sure what happens then. You do what they tell you to do."

Nico gulped hard. It sounded dangerous, but you couldn't jolly well ignore a dream visit from an Ancient God.

His father didn't appear to have anything left to say, so he prepared himself to leave when Hades spoke again.

"I have my suspicions that it was the Primordial God Chronos."

Nico racked his brains, trying to remember who exactly that was, maybe there was some benefit in paying attention in Chiron's classes.

"Uh…does that change anything?" he asked hesitantly.

Hades nodded solemnly. "Chronos is not any immortal Nico. His domain is time and is more massive and powerful than you could imagine. The Titan Kronos, my father, was simply able to manipulate and change time as it passes. Chronos the Primordial creates and weaves time itself in an intricate web. He has absolute control over it, but he is bound by even older laws to what he can and cannot do with him power, but without them, he could do anything he wished to do with time."

He paused, letting Nico absorb this information.

"If it is Chronos giving you a quest, he is likely to send you into a different point in time. Be it the future or the past, I do not know, but you should take note that wherever you are sent, if you accept…it is unlikely that you will ever come back."

Nico gaped. "What? So the quest could be in Ancient Greece, so he would like send me back to the time of Ancient Greece, but I wouldn't be able to come back to the present."

"Exactly what I am saying my child. You should be careful about your decision on accepting the quest."


Nico stared down at the bed before him. This was the thing that would change him. He was about to fall asleep.

In his dreams, he will meet an impossibly old deity who will give a quest. A quest that he may not necessarily be coming back from

His father had told him that he would be allowed to decline the quest, but really, does he want to? If he gets sent into another time, he could start again, no one would know him as 'the scary, freaky loner Son of Hades'.

He really had no one left that would actually miss him if he left, and on the plus side, the quest must be really important if an Ancient God was giving it.

He would feel bad if he declined the offer and put lives at stake simply because he didn't want to do it.

He sighed. "Well, here goes nothing."

He lay down on the bed and closed his eyes.

Nico stood alone on what seemed to be a balcony of a ship above some sort of liquid that looked darker than the Styx.

He knew that he was dreaming, and his heart was pounding. He knew what would happen next thanks to his father. The mysterious ancient Deity that is possible Chronos would find him, talk to him and possibly give him a quest.

Nico felt his aura before he heard or even saw him.

He stumbled backwards. The sheer amount of power possessed by the being currently standing behind him was dizzying. He had been in the presence of the Gods before, power surrounded them, but this being, power didn't just surround them, it radiated from them.

A steady hand caught Nico as he fell, disorientated by the energy levels around him.

It chuckled, a deep rumbling sound that echoed around the cavern that they appeared to be in.

"Niccólo Di Angelo." The voice was deep, kind and…old. Fatherly almost.

"Careful there little demigod, maybe you should sit down in my presence. It has been so long since I was in contact with mortals that I had forgotten what effect my aura has on you."

The hands propped Nico up on a chair that miraculously appeared.

The chair was turned around so that Nico could see the mysterious being.

He promptly shielded his eyes.

Nico remembered that Kronos the Titan had looked pretty much like a regular guy, except for the fact that he had golden eyes. This dude was almost the polar opposite of him.

The deity in front of him was completely gold, his skin was a dull golden colour and the suit he wore was a metallic kind of shiny gold, how that was possible, Nico wasn't really sure or concerned about for that matter. His hair was a golden blonde mop of curls that reached his chin. His eyes appeared to be the only part of him that was no gold, they were a very dark blue, they almost seemed endless.

They crinkled upwards as the deity smiled warmly at him.

"Your father was right my boy. I am Chronos, Primordial God of time."

Nico gulped. And tried to speak, but couldn't seem to find his voice. "So…so…uh…um…yeah…"

If anything this made Chronos smile wider. "C'mon now Niccólo, don't be shy."

"Nico." He automatically responded, he wasn't sure how it was automatic, as he couldn't remember anyone sans Bianca who had ever called him Niccólo.

"So…if you…if you are Chronos, that means…means that you are sending me to another point in time?"

Chronos sat down on a chair that had appeared behind him. "Only if you accept the offer for the quest that is."

Nico almost snorted. How come thing incredibly powerful God talked to him like he was a friend, Nico couldn't even stand in the presence of one of the Olympians without having to bow.

As if reading his thoughts Chronos chuckled again. "Ah now, don't compare me to my stuck up Olympian great grandnieces and nephews of mine. They are unbelievably conceited. The way I believe, as does every other Primordial, respect must be earned before it is given. You need not do anything silly like bowing in my presence."

The scale of what was going on hit Nico like a brick. He was talking to his…great great granduncle and each generation older than him got even more powerful. The Titans were more powerful than the Gods. The Primeval Gods were even more powerful than the Titans. And the Primordial Gods, which is what Chronos was, were even more powerful yet.

He felt a sudden urge to try and get this out of the way as quickly a possible.

"You said that there was a quest?"

Chronos' smile faltered slightly. "Ah yes, the details. I wish to send you on a quest that will save hundreds of lives if done right."

Nico nodded slowly and made a 'carry on' motion.

"There comes a point in time in the future where the people of the world find out about the existence of the Gods. To put it shortly, they hate them. The belief of the people is essential for the survival of the Gods. Without it, they would fade slowly and die. But belief fuelled by hatred, that is a different matter, dissolves them down until they are so weak they fade in a matter of day. The Gods are not there to protect human civilisation any more any they slowly spiral into civil war. They also start to tamper with genetics. Which, only leads to more and more problems. They begin to ruin the genetic code of the majority of humanity and so come up with the solution of conducting massive experiments, which, in turn fail time and time again. The amount of deaths caused by this is horrendous." Chronos started to describe.

He paused for a second and Nico frowned even harder. That sounded horrible, what on earth would Chronos want him to do about it? "So if I were to accept this quest...what would I do?"

Chronos pursed his lips, trying to think of a way to appropriately describe the task that needed doing. "I want you to try and help prevent the horrifyingly numerous deaths. In one of the experiments is a girl who plays a key role in several important events. The fate written out for her is tragic and painful. Should you accept, you would find this girl and try and help her avoid the deaths that occur."

Nico was taken aback at what Chronos wanted him to do. "What? Me? How?"

"You will still have your powers and they will be stronger than they are here because Hades is no longer using the darkness and shadows for his work. You are trained physically to a very high standard and you have fought in not one, but two wars. Nico, you vastly underestimate yourself. You are very good at strategising, fighting and would hugely alter the path carved out by the Fates." Chronos said earnestly.

Nico's eye's widened. "Wait what? You want me to go against the Fates?" He couldn't do that! That was impossible...right?

Chronos snorted. "The Fates do not control everything, they only suggest possibilities of what might happen. They can be changed as they are only the conveyors of Fate, not the creators. It is not difficult to change what they have written down as the future."

Gulping hard, Nico tried to think, did he really want to do this? Do something that contradicted the Fates themselves?

"Wont they curse me?" thought Nico out loud, curses from Gods were bad enough, but the Fates? They would make your life worse than Hades...right?

"Curse you? Of course not, they might be annoyed at you but I doubt they would do that. As far as I know, they are very fond of you."

"You...you know them?" gaped Nico.

Chronos shrugged "Reasonably well, I mean I spoke with Klotho the last time I was awake, which was...a few thousand years ago."

Nico almost laughed at how easily Chronos dismissed the Fates. He bit his lip, thinking.

On one hand, if he denied the offer, then he would stay with people that knew the real him. If he left he would have to wear a mask everyday and pretend to be someone else and live in a different timezone. At least in the present people respected him at least. Also, when he eventually did die, he would get to see Percy in Elysium, and Bianca, and his mother.

But if he accepted and left, then he wouldn't have people sneering at him, calling him weak, calling him a freak, calling him a loser. He could rebuild himself up to a new reputation platform. And besides, if what Chronos said was true, when it came to the point in time where he was being sent to, Elysium wouldn't even exist. It would dissolve along with the rest of the mythological world.

Was it really worth staying for something that will disappear anyway? He thought bitterly.

Thoughts dated back and forth in his brain, each seemed to be flying around, they eventually surrounded him, and buzzing demandingly, like a swarm of angry bees. He growled and dismissed all of them and something inside him just clicked.

Fuck it. Fuck it all, take this chance, I will never get another offer like this. Fuck everyone in the present, none of them care. Was the only thought left in Nico's head. I could stop thousands of deaths, why waste that chance for a life of being depressed and then being even more depressed in the afterlife? No one except possibly Hades actually cares about me here. Fuck them all, I'm leaving.

"Of course, I can hardly expect you to accept this offer. I am not trying to guilt trip you int-" said Chronos understandingly as he moved to go and stand by the balcony overlooking the strange waters.

"Okay." interrupted Nico.

Chronos blinked his deep, soulful blue eyes. "What?"

Nico took deep breath. "Okay. I am accepting this quest, I will do this and I will try and save those people."

Chronos carried on looking confused for a second and then his golden face broke into a smile.

"Fabulous!" he beamed. "Right okay are you read-"

"Whoa." exclaimed Nico. "Chronos you may need to explain a bit more than that if you want me to carry out this mission successfully."

Chronos smiled and Nico found himself having to close his eyes in order to get away from the light. Chronos' mood had drastically improved and now he seemed to glow with a white-gold light this bombarded Nico's poor eyes.

(Massive spoilers here, basically I tell you the plot of the Divergent Trilogy)

"The experiment that I want you to join, because the girl is in it, is in Chicago. The people in the experiment have had their memories wiped and therefore do not know that they are an experiment. They live within a fenced area, completely self sufficient and constantly observed by the world outside the fence. In the experiment, the society is split into five different 'factions'. When you turn 16- you are 16 right?"

"17." replied Nico.

Chronos wrinkled his nose. "Oh well, it'll do. When you turn 16 in the experiment, you choose which faction you want to be in for the rest of your lives. The factions are: Amity, who value compassion ; Erudite, who value intelligence; Candor, who value honesty; Abnegation, who value selflessness; and Dauntless, who value Courage. The girl you need to befriend is named Beatrice Prior, she lives in Abnegation, but will choose Dauntless at her choosing ceremony. Things work pretty well, but then Erudite starts to get too power hungry, and the leader of the Erudite, Jeanine Matthews tries to stir up a civil war against Abnegation, who hold the seats of power in their government. I want you to join Abnegation, the mist, which is very strong, will provide your backstory. You will have to pretend to be 16, and in two months after I drop you in, there will be the choosing ceremony and you must choose Dauntless along with Beatrice. The Dauntless initiation is harsh, but I have no fear that you won't pass it, you must aid her and others that you deem fit with theirs though. If they don't pass, they will be left to die."

Nico's eyes widened. They would be left to die? What kind of a sick society was that? Leaving people to die because they don't pass a test.

"I may speak to you on occasions, to provide you with more information. I will let you stay in Abnegation for two months before the Choosing ceremony for a reason. So that you can learn more about what's going on in the experiment. You will be in Abnegation so you will not be required to speak that much, but I have a feeling that you will like Dauntless. Ah wait, one more thing you should know, the factions have a serums that affect the human body's brain in some way shape or form. They have several, the Truth Serum that makes you tell the truth; the Peace Serum, it calms your mind but causes you to forget why you were fighting; and the Memory Serum, it can erase parts of your memory or even all of it. They also have several very dangerous ones which have been tampered with By Jeanine Matthews, the leader of Erudite. The Simulation Serum, it makes you see things that aren't real, in the Dauntless Initiation you are injected with it an you see your worse fears; The Paralytic Serum, which, paralyses you; and... the Death Serum."

Nico's face had been slowly curling in disgust as he listened to Chronos. It must have a pretty fucking bad time for the world if they were desperate enough to wipe people's memories, put them in an enclosed area and force them to live a life without knowledge of the outside world. And what kind of people invented things that causes you to hallucinate and forget everything and...die? "Death Serum?"

Chronos nodded tiredly. "It was not originally given to the people in the experiment, but Erudite developed the Paralytic Serum into the Death Serum. You will notice when you join, they are exactly the same shade of purple."

"Erudite sound despicably twisted." said Nico.

"Most of them aren't, it just so happens that those in seats of power, are." sighed Chronos. "I should tell you this as well. There are group of people who can, ah...resist the Serums. They are called Divergent. The humans think that they are 'genetically healed' due to the fact that many of them are 'genetically damaged' due to the genetic tampering that took place a few decades before. But, the Divergent aren't just 'genetically healed', they are the legacies of Greek Gods."

Nico blinked. "Legacies of Greek Gods?"

"Yes. Their ancestors were demigods who survived. None of the mortals know that though, their powers are so diluted by mortal blood that they cannot perform any magic or and skills that you or your demigod friends can, but they cannot be controlled by Serums."

Chronos paused, looking at Nico cautiously. "You think you can handle this my boy."

Nico ran his hand through his dishevelled hair. "Why can't you do anything to stop it? You are still there, right? You could do much more than I can."

Chronos pressed his lips together tightly and then gritted his teeth. "I wish I could my boy. But I, like your father, am bound by ancient laws that forbid me from directly interacting with humans. I could ignore the rules I suppose, but that would just provoke the end of the existence of my own life. Which would achieve nothing, I cannot help if I am not there anymore."

"You can die?" whispered Nico, unable to comprend how such and ancient and powerful deity could...die.

"No." said Chronos shortly and Nico almost exhaled in relief. "But I can fade. Just like your father will along with his brothers. I know not who carries out the punishments for disobeying the Ancient Laws, but I know that they are definitely carried out. If I were to I break the Ancient Laws, I would fade almost instantly."

Nico was silent for a long time. "Can I speak to my father before I go?"

Chronos nodded. "Now or when you wake up? I can summon him here if you want and you may speak to him, or you can wake up in the morning and then speak to him. After that, then I will transport you to the future."

Nico thought about it. What did he want to do? "I want to see Camp Half Blood once before I leave if that's okay."

Chronos nodded. "That is fine, but you cannot tell anyone of your quest except your father. Once you have told him, I shall take you back here and you shall leave for your quest directly afterwards."


Waking up in the morning felt rather peculiar.

Nico walked out of the Hades cabin and watched as the happy faces of the campers passed by him. They didn't know their parents would fade. They never would, they would die thinking that the Gods would live on forever. And he couldn't tell them.

And he would never see any of them again. He would never see Chiron again, never see the dining pavilion, or Thalia's tree, or the climbing wall, or the lake again.

And the strangest thing? He was ready for it.

They didn't want him there.

He didn't want to be there.

Now he had the chance to leave.

And he was taking it.


"A quest to the future?" Hades eyebrows furrowed in worry.

"Yes father." nodded Nico.

Hades rubbed his forehead and looked tiredly at him. "Chronos said that your powers will be much stronger in the future did he not?"

Nico nodded.

"Let me try something." Hades beckoned at him, Nico obeyed so that he was now standing directly in front of Hades. "Close your eyes."

Nico looked at him nervously but did as he was told.

He felt Hades place his fingers on Nico's forehead. Suddenly the area of his head in contact with Hades' fingers began to warm up. Nico almost yelped in surprise.

"Stay still Nico." commanded Hades.

He gulped, but stopped moving. His forehead started to feel very strange, like something colds and slippery was seeping out of Hades' hand and into his brain. Then Hades removed his hand from his son's head.

He opened his eyes. "What did you do?" As far as Nico could tell, nothing had happened.

Hades looked like he was trying to smile but the muscles in his face were so unused to it looked like a grimace. "I gave you the knowledge of how to use your powers should they ever become as powerful as mine. If you possessed this much power, you could cause as many deaths as you are trying to prevent at an accidental flick of the wrist."

Nico blinked at him. "Thank you." he whispered.

Hades sighed once more and pulled Nico into a tight hug, which did cause Nico to yelp.

Hades pulled back and looked at him at arms length. "Nico, I know I am not the best father at showing...love. But make no mistake my son, I am proud of you and I know that you will carry out your quest to the best of your ability."

For the first time in weeks, Nico's face broke into a smile.

His father was proud of him. Of him. He had called him son.

"Goodbye father." his whispered at him, as he felt his eyes closing and himself being transported away.

Hades tried once again to smile at Nico. "And Nico?"

Nico forced his eyes open and watched his father throughout the golden haze that surrounded him.

"Good luck."

Hades looked at his son for the last time as he was engulfed in golden light.


Nico looked in disapproval at the boring grey clothes Chronos had dressed him in.

He hesitated. "Chronos, is there any chance I will come back?"

Chronos looked at him. "There is a very small possibility, but it is extremely unlikely."

The silence that followed seemed impossible loud.

"Are you ready?" asked Chronos.

Was he ready? Was he ready to go in a world with no one who knew him? To try and stop these horrendous experiments? To try and stop all those deaths?

He wasn't sure.

How could the Ancient Gods sit back and watch as this happened? And do nothing, watch as hundreds of people died? Nico stopped. They weren't doing nothing. They were doing all they could to stop it, they were sending Nico to help them. If he didn't go, then no one would.

He had to do this.

"I'm ready."
