chapter 1

3rd POV:
It's been two Years since percy crashed on Remnant in that time he has explored the world seeing all it has to offer. He is now seventeen(because he was fifteen when he crashed due to the void changing his age when he was transported to the Zarumon ten-zero) and has improved his physical and void abilities by training with umbra. He now has the speed and strength of a Pro-huntsmen. He can also hold his invisibility and mind spike for an indefinite amount of time, the mind spike can also became so strong that it can disintegrate a deathstalker in an instant and can teleport across the entire ocean between Vacuo and Mistrial with minimum effort and store things in the voig like supplies weapons and Umbra. He is currently making his way towards Vale for the beginning of the school year at Beacon. We see that he is walking toward Vale in his casual/combat cloths,

(This is what he looks like just get rid of the gold crown)
he starts thinking about how he got in to Beacon.
Flashback (6 months before main story line)
It's the final round of the Mistrial regional tournament it's Arthur Vs. Pyrrha Nikos. As they walk into the Arena the Announcer starts talking through P.A system.
Announcer:"Here it is folks the Final round of the tournament who will come out on top OUR REIGNING CHAMPION PYRRHA NIKOS OR THE MYSTERIOUS FIGHTER ARTHUR!?! FIGHTERS GET READY!"
After the Announcer says this the crowd starts cheering. Pyrrha gets into her stance as Arthur pulls his trusty sword the Skiajati from the void.
Announcer:"FIGHTERS READY. THREE, TWO, ONE FIGHT"
With that both fight rush at each other. Pyrrha makes the first move by making a over head slash at Arthur. Arthur then unsheathed his sword to block and try to kick Pyrrha but Pyrrha blocks his kick with her shield but it still pushes her back a bit. With that Arthur goes on the offensive and starts attacking Pyrrha with stabs and slashes from his sword making Pyrrha go on the defensive blocking  and dodging whatever she can but still takes alot of damage. Pyrrha is then able to get Arthur off balance and shield bashes him to make space between them. Arthur then stabs his sword into the ground to stop him from sliding and pulls his sword out of the ground.

(From 1:08-1:15)
They rush at each and start attacking each other going blow for blow until Arthur stops right as he is about to give the finishing blow and raises his hand.
Arthur:"I forfit."
And walks out of the Arena. A few hours later as Arthur is about to leave Mistrial he is stoped by by Pyrrha who give him something.
Pyrrha:" Here you can have it. It's a invitation to any huntsmen academy you want. I don't need it because I have already been accepted into Beacon."
Arthur:"Thank you Miss Nikos i guess i will see you at Beacon. Good bye."
Arthur then teleports away to start making his way towards Vale.
End Flashback
When he gets out of his memories he notices that he is near the walls of Vale and teleports over them to get in the city. As he is walking through the streets Arthur comes across a store called 'Dust' till dawn'. As he is walking past the store two people fly through the window and land in the street. One of the people who came out of the window who appears to be male is unconscious while other who is female is on top of others body. The female is wearing all black with red highlights and a red cloak and a red and black box attached to her lower back she also has black hair and sliver eyes. Arthur then teleports to the roof of the building to watch and not get involved. Once he is on the rooftop he looks down and sees the girl take the box and spin it behind her back as it unfold in to a giant scythe. As she does this more thugs come out of the shop with their leader who is a guy with orange hair, wearing a white coat, a black fedora with a red line going through it, and smoking a cigar.
Fedora man:"Well? Get her."
He says while looking at the other thugs.
The thugs then rush the girl. Once the thugs get close enough the girl starts attacking them taking them out one by one until only the boss remains. The fedora man then takes his cigar out of his mouth and puts it on the ground to stamp it out.
Fedora man:"You were worth ever cent truly you were." He says while looking at one of the downed thugs.
Fedora man:"Well red, I think that we can both agree that this has been an eventful evening and as much as i would love to stick around this is where we part ways." He says while he lifts his cane and ponits as a crosshair flips out from the bottom of the cane. Then a red explosive comes out of the cane and launched at the girl. The girl then uses her weapon to launch herself into the air to avoid the explosion, but when she landed she saw that the Fedora man was gone. She looked around to see that he was climbing a latter going up to a rooftop, she turns around to see the shopkeeper and ask if she can go after him. The shopkeeper nods and the Girl uses her weapon to launch herself on to the rooftop. The Fedora man hears the girl land turns around to face her.
Fedora man:" Persistent." He grumbles. A bullhead then appeared and the Fedora man climbs in and turns around to look at the girl.
Fedora man:"End of the line red!" He then throw a red dust crystal at the girls feet and shoots it. Just as the crystal exploded another person appeared shielding the girl with a purple glyph. This new person is a white female with green eyes, glasses, black with green crystal earings, a sliver necklace with a green crystal, waering a white top, with a black dress skirt that goes down to her knees, with high heels and a riding crop.
(With Arthur)
Arthur:"Well i've seen enough." With that Arthur gets off the rooftop he was one and starts look for a place to say until tomorrow because tomorrow is the day he starts his new adventure at Beacon.
(In Ozpin's office after his talk with Ruby)
Four people stand in front of Ozpin. Two male and two female. The first male has sky blue eyes and blond hair. The next male has black eyes and black hair. The first female has grey eyes and blond hair. The second female has electric blue eyes and black hair.
Ozpin:"I must thank you Hero's of Olympus for coming to aid me and my people in our fight. Can you please tell me what your names are."

???:" Jason Grace."

???:" Nico Di Angalo."

???:" Annabeth Chase

???:" Thalia Grace."
Ozpin:" Well initiation is in 2 days so feel free to hang around the school grounds until then." With that the four leave his office ready for whatever comes next... or so they think because a old friend of theirs has returned and they don't even know it.
