Welcome to a triple crossover which includes in terms of relevance to the story; PJO, F/SN, Campione! In other words 1 main character from F/SN with some references to campione in the PJO world hehehe

*Spoiler*

The main character is Shirou YAY! He's a mixture of Emiya Clan Shirou which has traveled to multiple dimensions and he is a campione! Don't expect him to use most of his spells though tracing is one of his many first options before resorting to his backups and as a last resort his Reality Marble (UBW) though since he has travelled to many different places expect him to pull some swords from different anime's (though I'll try to stay as original as possible) and before anyone asks the heretic gods he slayed add up to 6. 2 of which are (the black knight Sir Morgan, and Xolotl of the Aztec's) yes he killed a Persian, deity as well as another British deity the last two are a secret though *winks*. Now on to the relation to the Percy… ah you'll find out next chapter I don't reveal all my secrets ^.^ people might or might not join from other worlds so just tell me which ones you want later on k?

*Spoiler End*

I do not own any of the material I write about except intellectual ideas and OC's note to this point PJO Campione! And Fate/Stay Night belong to their own intellectual owners.

Prologue

Dear Everyone,

Through Fate we have been transported to another dimension that is not our own, seeing how Fate itself talked to us about our involvement in this world we have to stay though in 16 years' time a portal big enough to fit 5 people will open in the location of our old home, until then we will have to stay here or the fate of this world would be in ruins. This may not me what you like but it is needed I will not risk the fate of a world over selfishness all of you know that from me so until then please prepare for that portal to open.

With love

Shirou Emiya, Illyasviel von Einsbern.

-Line Break-

When people ask a question as simple as "would it be cool to visit another world?" you think outside this planet as in outer space right? Well for me and my little sister it's more than that we would not be called space travelers, we would be more to the extent of dimensional travelers seeing as how we have already visited several dimensions on our way back to our home dimension, easy right?

Wrong.

The number of times we have been caught up in circumstances that could lead to the end of the world produced by some idiot's hopefulness for gaining power is countless. Imagine our surprise when we finally find a portal leading to yet another world only to have 3 old woman known as the Three Fates arrive before us in that new world to give us a choice to stay in this world to literally save the world from The World in the future 10 years or go back to our dimension and leave them to their fate.

I being the supposed hero I am chose the obvious option.

Yes, I stayed as I always have because I will not allow someone to die because my selfish decision, I will not allow fate to play out badly even if it kills me to do so.

Why you ask?

The thing that drives me so far are my own ideals though toned down with the help of my largely extended hare- family, my ideals have been toned down quite extensively yet I cannot and will not let someone die or rot before my eyes even if I have a list of priorities now.

That led me to the current situation.

You might think 'it can't possibly be that bad for you' well thanks to my damned E rank luck or maybe because Akasha just loves messing with my life, because following the meetings with the fates in my head I regained consciousness to witness myself and Illya falling to the ground at the speed of a miniature rocket. I gently pulled Illya towards me and carried her bridal style before imagining the cocking of a gun, pulling the trigger.

As the imaginary shot burst from the barrel I yelled "The fires of Humanity aid my cause" and used the authority of the Aztec god Xolotl. Summoning the magic portion of my authority I slowed the descent of our fall and aimed toward the roof of a very tall skyscraper.

Letting out a sigh of relief I landed on the roof, I released my hold over the authority and allowed the slow fall spell to dissipate, then placed Illya gently on the cold hard ground as to get a better view of where and when we are. I walked towards the edge of the building trying not to imagine what horrible place I landed in this time, as I reached the edge I saw sky scrapers tall as the eye can see and cars that were going through streets even though it was night. I quickly deduced where I was due to the sight I saw, the largest sky scraper in the city, the empire state building. My eyes traced the length of the empire state building from bottom to top. I peered at the top of the building somewhat lost in thought remembering how I entered the dimensional portal in Japan and ended up in North America, New York out of all places, I was about to break contact with the building before a glint far above the building caught my eye. I focused on the shine and reinforced my vision and saw…

Whoa…. NO No that can't be. There is no way something that large can float above the empire state building…

I rubbed my eyes as I took another look at the tip of a mountain floating above the top of the empire state building.

I released a sigh as I thought 'yup, of course my luck sucks this time I landed in a place with floating tips of mountains located above famous buildings' I shook out of it and quickly turned back to go see how Illya was only to see her standing right behind me staring at the same object I was seeing which was defying the laws of physiques.

Now I can honestly say that the only way I can find a peaceful place is to first find my grave.

After happily seeing the rules of gravity defied to such an extent I could honestly say that I'm not the weirdest thing that ever existed. I dragged Illya down the rooftop as we discussed what we saw and how after having conversations with multiple people about what's above the empire state building and many people looking us weirdly, asking if we need a doctor, we figured that people not related, or people that don't know the existence of magic bar a few lucky ones could not see magic or saw it as something else entirely.

At the end of our investigation we found ourselves with several things such as: we were currently in New York. 1993, in Japan there was no place named Fuyuki city, monsters roamed free in New York city, and with the help of Illya me and herself interrogated a monster which revealed to us that Greek Gods exist above the Empire State building with physical forms and it is the Age of Gods, and even more the planet doesn't have any sentient being limiting the activation and usage of magic.

That is how we started our lives in New York with the Gods of Greece and Rome looming above our head, everything was beginning to roll down the metaphorical slope and the only thing to stop this was me and the only people available to face the threat the fates talked about is us, and the Greek and Roman Demigods that know nothing of each other and if they did would probably go after each other's head. Everything is great.
