Worlds Collide.

Chapter 2: Origins.

The universe was a vase place, and there wasn't just one reality, one universe. There were many different ones. In one you could have simply chosen to do something different, like not marry the person you did in another or were even born earlier or later, sometimes even a different gender.

It was still you but there were differences. Be it gender, age, a decision chose differently or even bits and pieces of ones personality.

Sometimes the world mirrored one another but with one subtle or mind blowing difference.

The very first universe created was that where the Olympian gods ruled, where they were petty and paranoid at times, even cruel in their past but they were the better rulers compared to the Titans. But Chaos loved her children and their children and so on and so forth.

The Titan's were born of her daughter Gaia, and despite everything Chaos took pity on her grandchildren. They were her blood, her family, so she created a mirror world of the first universe – the first time she'd done such a thing and realized she could make different realities, different universes.

In this reality, a world known as 002, there was one big difference. The Titans never fell, but other then that they were more just in their ruling, much more like the gods of the first world. Yet some could argue that they learned from their mistakes quicker, with the help of Rhea they became even more just then their early years.

Instead of jumping to hasty actions and eating his children, Rhea convinced her husband that they could raise them right. That the prophecy might just be self fulfilling, that it couldn't come to pass if he didn't do anything negative to them. Like eating them for instance.

It took some convincing but despite how it seems the Titans could love, and Kronos loved his wife.

So he agreed, and Hestia was spared. Hades, Demeter, Poseidon, Hera and finally Zeus. All raised by their parents and the other Titans, but even Chaos could not stop the prophecy given from coming to pass.

So the gods grew up together yet Kronos could see the signs of rebellion. He wished to ignore it, he had come to care for his children deeply, even if they were oddly aggressive the older they got concerning mankind.

Then Zeus hit adulthood and the war between Titan and God began.

This is where history really changes, instead of fighting for freedom, for the good of the world the gods were fighting for power. They wished to over throw the Titans, thinking they could do better then the golden age Kronos and Rhea ruled over with their siblings and their siblings children.

The six gods were not happy with the power they had, with the lot life had given them. They wanted more.

But they were fighting a loosing battle. For Chaos had created this world for the Titans. It was fated that they win, and the gods were thrown to Tartarus. This did not last, for in Tartarus they were whole and they were growing powerful. Especially as Hera and Zeus birthed children. Ares, god of war. Eris, goddess of strife and discord. Hebe, goddess of youth. Hephaestus, god of forges, fire etc.

A century passed and the gods were powerful enough to break out of Tartarus, and so they did. They fled to Mount. Olympus, and began to have man worship them as well. The Titans knew war was to come but they had no idea it would last as it did. Victories were won, though many were lost.

Some of the Titans perished in battle – Pallas for instance fell to Athena the product of Zeus and Metis. But they won a great victory by forcing Hephaestus to carry the burden of the sky, freeing Atlas at long last.

So it waged, a new age, a power struggle between the gods who wished to punish mankind and rule the world with an iron fist. And the Titans who simply wished to rule as they had before, a golden age many called it.

The one thing the Titans were grateful for was the fact the gods, the Olympians, seemed to have no desire to mate with mortals. There would be little worry of demigods to fight the Titan's demi-titan children. Not to say some demigods didn't pop up every now and then. But they were few and very far between.

Chaos realized to late the mirror world she created may never find peace, not until the gods of that world were banished to Tartarus for good. Much like most the Titans of the first world were. But she could do nothing to help, she was forbidden to interfere in the way of life even immortal lives.

The centuries raged by and finally after many battles the Titans were able to seal the twelve – eleven since Hephaestus still carried the curse of the sky on his shoulders – into the depths of Tartarus.

And so the world had peace, and things began to change. A new golden age, while the first world moved on from Greek/Roman mythology to welcome in Christianity, nearly forgetting the gods or Titans they'd worshiped for eons, this world did not.

The Titans couldn't allow it, they'd worked to hard for this. Mortals knew of their existence, the Titan's they prayed too and worshiped. They chose to be public of their existence, to not hide. And it made them relatively stronger then before.

Though it was still a free world and some did move forward with Christianity (many, many years later then in the first world), and even with their belief in the Olympian gods. The Titans chose not to notice or care, but the majority of the world looked to them as their gods.

Even when western civilization changed and move the world stayed the same when it came to sacrifices of food and artifacts to the Titans, and temples built.

The birth of demi-titans didn't change either. A camp was built for the mortal children of the Titans, Camp Half-Blood and it was run by Theia and Prometheus. To train and educate the demi-titans to survive in the world, from monsters and such.

Then things changed, a prophecy was spoken in the 1940's about a child of the Titan of Time either saving or dooming Othrys. A pact was set, Kronos would have no more demi-titan children. But all pacts are broken sooner or later and Kronos had weaknesses, women being one of them.

In the span of three years he inadvertently spawned three children. He was uncertain what to do. He'd faced a prophecy before and he'd payed a price for listening to Rhea, for not swallowing them when he had the chance.

Yet he could not bring himself to do that to his three newest children, mortal children at that. He was sometimes a cruel Lord but he wasn't the same as he'd been before the wars.

So he left it be, and everyone wait.

The three children of Kronos of difference mortal women grew older and eventually came to camp, meeting and becoming close friends. Quests were set, battles were waged, gods began to raise from the depths they'd been cast into and war began to plague the world again. Then the oldest turned sixteen and things changed.

After great betrayal and hurt along with a ten year war the Titans were able to drive the gods back to Tartarus were they belonged, and the the Underworld was given a new Lord. A Titan who could handle the task, a son of Kronos once a demi-titan now a Titan like his two siblings.

Now the world once more knows peace, though it is only a year after the end of the third Olympian war. It had been nearly a decade since three new Titans were welcomed to the family, the three great heroes of the war.

Percilla Jackson was the eldest daughter of Kronos and Sally Jackson. She looked like a mix of her mother and father and was unique even as a demi-titan.

Her mother had been a daughter of Oceanus, a demi-titan herself so Perci was able to control water in many forms just as her mother had been able to. She had been the child of prophecy, but she couldn't have done it without her brothers help.

She had been eighteen when the Titans had made her a Titan as well, knowing that it would be needed after not only Zeus, Hades and Poseidon escaped from Tartarus but so had the other Olympians. She was the Titaness of deception, loyalty and war.

Thalmus 'Thal' Grace was the middle son of Kronos and Crystal Grace. He was an enigma all in himself, and single handedly fought Zeus, while Perci took on Poseidon and their youngest brother took on Hades.

He had been seventeen when he was made a Titan so that helping Perci wouldn't end in him dying. Not to mention it was painfully obvious Perci wouldn't have agreed without her brothers. He was the Titan of storms, gravity and patience (how he got the last one none knew seeing as he was rather impatient at times).

Nicodemus 'Nico' di Angelo was the youngest son of Kronos and Maria di Angelo. He was the darkest of his siblings, and just as ruthless as his siblings in battle. He was sixteen when he became the Titan of rage, wealth, and death. The Lord of the Underworld.

You can imagine it was a great surprise when the three children of Kronos were taken from their domains or temples and appeared before the three most powerful being in the cosmos.

"Where are we?" Thal demanded, his hand going for his spear. Nico had a hand on his own weapon, a dark sword.

Perci just stared, looking from Asteria, Astraeus, towards the three imposing figures. Suddenly her gold and sea colored eyes widened.

"Lady Chaos, Lady Ananke, Lord Chronos," she said.

"What?" Nico asked, looking at Perci in shock. Thal was blinking, surprised.

"Asteria, Astraeus... I don't think we're in Kansas no more Toto," Thal said. He wasn't the best at remembering history but he was pretty sure both Astraeus and Asteria had faded eons before the three of them were even thought of.

"We apologize for the inconvenience," Chaos spoke, and instantly the three Titans felt calmer. Nico even released his unsure hold on his sword which hung at his waist.

"What are we doing here, where is here?" Nico asked.

"You are in the very edge of the void. Further behind us is where all faded immortals go to rest," Ananke answered this, shocking the three new comers even more.

"You wonder why you are here?" Chronos asked suddenly, just as Perci was about to open her mouth to speak. "As you may know, my daughter, Chaos is the creator of this universe but her powers can be used to make... alternate universes. Other realities."

The children of Kronos exchanged looks.

"Yes, but what does that have to do with us?" Perci asked.

"When I was still a rather young goddess I helped make this universe, but eventually a prophecy was spoken, much like the one in your world about the a son of Kronos overthrowing him. I felt pity for my daughters children, for my grandchildren so I used my powers to create a mirror world, with only one difference." Chaos gazed at the three Titans before her.

"In this world Kronos swallowed his children to stop them from overthrowing him. In your world Rhea was able to convince him otherwise. In both world there was a war between Titan and God, but the rolls were reversed. Here in this realm the Olympian gods are the good guys while in your world the Titans are. Here the Titans received the punishment the gods did in your world and so on and so forth. The prophecy which you Percilla fulfilled is also in this world and your counterpart has wished for help."

The Titans were frozen in shock.

Their world was just a second thought? There was a world where their family was as bad as the gods, where they had not won? What really freaked them out though was the story of their father having swallowed his children. They knew Zeus had swallowed poor Metis after their affair to get her out of the way, and latter Athena was born in battle from his cracked skull, but this was different.

They didn't like the gods though so they didn't care much for that factor just that in this world their father would be... so cruel and if what Chaos said true, evil, took a bit to sink in.

"My counterpart? We have counterparts in this new world?" Perci asked.

"Very much so," Ananke said, smiling slightly. "His name is Perseus Jackson, he is the child of prophecy here but he does not have the experience you had, nor the confidence or strength. He wished upon a star for help in his war, to defeat the Titans."

The three Titans flinched slightly. They weren't used to Titans not being the good guys.

"So we brought you here from your world to help," Chronos finished for his wife.

Chaos then pulled out a circular mirror almost as big as a humans head. It glowed for a moment and then Chaos willed it over to Perci.

"This is a device which will allow you to contact your home world, so your family will not worry. It will only work on Olympus though, so you must be there to use it."

"Where is this Olympus located?" Thal asked.

"The same place your Mount. Othrys is located of course," Chaos said. "The 600th floor or the Empire State building."

The three Titans twitched but nodded.

"Percy Jackson will meet you three at the building tomorrow at noon. Try to lay low until then," Chaos said, and then snapped her fingers and the three Titans shot to earth.

"I hope you know what you're doing mother, father," Chaos said, sighing.

Ananke and Chronos smiled.

"Of course we do," Ananke said, and the three beings watched the earth once more to see what would happen next.

xXx

Percy knew he was dreaming, but he also knew that didn't make it any less real. Demigod dreams were a real bitch at times. Appearing in this dark void like space only surprised him slightly. It was the woman who greeted him which shocked him. She was classically beautiful, but she had to be a goddess with the glow and power she sent out.

"Hello Perseus, son of Poseidon," the woman spoke, her voice soft yet clearly heard. Almost like a powerful and clear echo.

"Uh...who are you?" He thought at first he might have just signed a warrant to be incinerated.

He'd learned in the past gods has short fuses and he had many out for his blood so he thought himself a expert at pissing off the gods.

Fortunately the woman with dark eyes and hair laughed. "You are a strange one Perseus, but to answer your question I am Chaos, the being to which gave birth to the universe. The primordial goddess of nothing from which all else springs, and keeper of the void."

Percy blinked. "The void?"

"Of all the questions to ask, you chose that?" Chaos inquired with amusement. "I can see why my parents and Asteria and Astraeus wished to grant your wish now. The void is the place were immortals go to rest once they fade."

Percy's eyes widened. "Like Pan?"

Chaos smiled. "Very much so. He enjoys his life here I assure you."

Percy looked around him, surprised. "It doesn't look like much."

Again the goddess laughed. "This is simply a check in station I suppose you could say. The city is beyond the throne, but is unseen by mortal eyes unless escorted there."

"Oh," Percy said then he thought of what she'd said before. About a wish. "Whoa, wait you said something about a wish. My wish?"

She smiled. "I see you caught that. Yes, you wish was heard and caught by the left over power and spirit – for lack of better term – of two former Titans. They are one of the less bitter Titans from the war eons ago, they wished to grant your wish but needed the help of my parents and I."

Percy was lost for words. Two Titans had wanted to help him? He supposed not all the Titans could be like Kronos, Atlas or Iapetus. Calypso for instance, and he supposed she was technically a Titan even if she was considered a Nymph in written accounts.

And Zoe had been born from a Titan, and she'd been a Hesperides before her exhale. What had that made her before she was a Hunter, a Titan or a goddess?

"How? How can my wish be granted?" he asked.

"It already has my child." Chaos smiled maternally. "I created this universe but I hated to see my children's children suffer, even I did not think how the Titans ruled were right. So I made my first alternate universe, a mirror world with just one difference. The Titans were the good guys and the Olympians were not."

Percy's eyes widened. "Like Opposite day?"

Chaos blinked. "Yes, I suppose. It's a bit more technical then that, it was actually one difference that made the Titan more like the Olympians of this world. Unfortunately I underestimated how little I could influence this reality after it was made and there are many differences between the two. Like the fact there were two great wars before a prophecy like yours was made."

"So, how does this help me?" Percy asked.

"Everyone has a counterpart in any reality. Even if it's not the best kind of counterpart, some may even have died but that of course wont effect the others. Now, like there is demigods in this world that are heroes, that role falls to the demi-titans of that world."

"demi-titans," Percy muttered. "Are they real here too?"

Chaos sighed. "I don't believe so, most are imprisoned. They have no time to copulate with mortals. Once upon a time before the wars there may have been a few but they were rare."

"Oh," Percy said.

"Your counterpart you can imagine is a demi-titan, as are all your friends. Well most of their counterparts, I believe the one you call Annabeth was the Oracle in their world."

Percy blinked, that was different. He couldn't imagine Annabeth sitting around like the mummy and burping green mist and prophecies.

"Your counterpart has completed her prophecy, and she along with her siblings – I believe they'd be your cousins in this reality – were made into Titans just to be able to do this."

"Did you just say SHE?" Percy asked, his head snapping up in surprise.

Chaos smirked. "Why yes, I did. Percilla, or Perci as she prefers is your counterpart. Don't worry, you're not the only one gender-bent."

"They're already here then?" Percy asked, curious. He wanted to see how different being a Titan or demi-titan made him-her.

"I've already sent them to earth. They've been instructed to meet your at the empire state building tomorrow," Chaos said. "At noon. Now it's getting late and you need your sleep so we must finish up here."

"What else is there?" Percy asked and Chaos stepped forward.

Without warning she pushed two fingers to his forehead and he gasp, images of memories filtered behind his closed eyelids. He saw images of war between the Titan and Gods but it was the reverse of what he learned in this world.

The Titan were the good guys, just as Chaos had said and he saw a side of Kronos he never imagined existed. For one he hadn't swallowed his children, he'd ignored the prophecy and his paranoia for his wife. Yet he watched in horror as the Olympians, including his usually laid back father turned on their family.

He saw the peaceful years, the way the world was ruled even into the modern age by the Titans and while there were battles with some mortals who did not wish to worship the Titans. Even though it seemed the Titans didn't mind the mortals having other religions, some still prayed to the Olympians, others to the Christian God.

It seemed there weren't many of these mini-wars between human and Titan. He saw Camp Half-Blood in a different light, run by two Titans who he couldn't recognize.

He saw the quest which mirrored his own but for the Titans, and the gods being the ones rising. He saw the ten year battle, he saw his counterpart and Nico's and a boy who looked like Thalia becoming Titans and battling the gods and eventually seeing them win, forcing the gods back to Tartarus once more.

He opened his eyes, knowing once and for all he could trust the three sent to help him. He just hoped the gods could trust him and the three Titans willing to help them.

"Good luck, Percy Jackson," Chaos said and waved a hand.

Percy woke up to alarm clock beeping in the same instance.
