(All) Big Three kids (+ Male! Thalia) accident end up in Ancient Greece
When Theo, Jason, Percy, Tyson, Nico, Bianca, and Hazel end up in Ancient Greece they’re all split up into three groups dictated by who their godly father is.
So it goes like this, Theo and Jason are having a reunion and freaking out and Theo is cursing Beryl out over abandoning Jason (and mentally cussing Hera out). They’re attracting attention from the people around them as Theo is taking his anger out on the monsters that come their way, Jason is trying to calm him down and think of how they’re going to go back home. But both are summoning storms and lighting, sparking whispers and rumors about two extremely powerful sons of Zeus (from the sane mother) who channel power from their father’s domain. Zeus sees the storms and lighting used by Theo and Jason, he looks to see where this is all coming from and sees two channeling lighting like it’s nothing and starts getting flashbacks to his early days
Percy and Tyson freak out as soon as they wake up in the middle of nowhere and realize where they’re at and Percy is actively crashing out at his situation, causing a storm in the background while Tyson tries to calm him down. Tyson suggests sticking to the coast and asking their father for help, Percy isn’t too sure on the idea actually working but since Tyson’s idea is the only thing they have he agrees on it. Poseidon hears two prayers for help from two threads with echoes his power and looks for where the prayers came from. He’s surprised to see a young cyclops and a young man with his features praying to him (don’t know if they’d go to one of Poseidon’s temples), he looks at their scents and is shocked to see the power radiating from them, and they’re also his.
Meanwhile Nico wakes up and sees a living Bianca in front of him and doesn’t know what to do, he’s also probably crying and breaking down. Bianca doesn’t know what’s going on but she’s happy to see Nico again, at least now she can hug him again. Hazel is trying to help her brother not crash out, she’s worried over what’s going on due to Bianca’s apparent resurrection and then being stuck in a strange place. However she also gets pulled into a big sibling hug by Bianca, who’s both surprised and happy to have a younger sister. They decide to take the risk of going to visit the Oracle to get answers, unlike the other two groups they don’t actively draw attention via creating storms. However Nico’s shadow traveling and Bianca trying to learn it so Nico doesn’t have to be the only one doing it (and getting exhausted) draws some shocked expressions whenever they end up in the wrong town or city. Bianca accidentally summons an army of skeletons once while testing out the untapped Child of Hades powers that she never got into while alive. People murmur about the strange trio made up of two young women (one far too pale for a normal person with a bow and arrows in her possession and another with mesmerizing golden eyes with a golden sword in her hand) and a young man (too pale and with too dark eyes, a black sword strapped to hip). The death seem to take orders from them, with the shadows being their favored way of travel. Hades is confused when the terrified prayers from mortals stark coming, actively promising that his three children (two girls and one boy) would be treated kindly while they stayed in their town
A funny dilemma Theo and Jason come across is that Jason cannot speak Ancient Greek—he can somewhat understand it but he can in no way speak it. Which leads to a merchant seeing him eyeing something and asking if he'd like to buy it but Theo is preoccupied—
Jason Internally: Fuck! Okay! Calm down and think! Modern english would be too weird! So what is the oldest language you know!?
Jason: ...*starts speaking in Latin*
Theo & Jason: *Back on the road*
Theo: ...You know you're gonna have to respond to everyone we come across in Latin now right...?
Jason (In Latin): Why is he calling me his son? I'm not his son!?
Zeus: What's wrong with his mouth?
Theo: We...weren't raised together, it would have attracted too much attention...
Theo (In Broken Latin): The split hasn't happened yet, sooo yeah...you're his kid...
Jason: ...but I don't wanna be his kid...
Theo (In Greek): *Sad sigh* Me neither brother...
Jason (In Latin): *Standing over a monster carcass* Brother! It bleeds!
Theo: *Equally shocked and noticing he himself blood covered* That it does!
Zeus Internally: Ohhhh I may have to end these two if Hera doesn't—
Poseidon: ...How did I miss two—wait what are you two doing together?
Percy: *In the most "duh" sounding tone* We're brothers...???
Tyson: We're sorry dad, we wouldn't have bothered you but Mom isn't here for us to ask for help.
Poseidon: You two have the same mother...!?
Percy: Basically? I mean, we kinda found him in a box.
Poseidon: ...I'm done questioning this—
Ancient Greek Commoners: *Minding their business*
Hades' Kid: *Crawl out of the Shadows like fucked up Gremlins*
Commoners: "HOLY SHIT—" "WHAT THE FUCK—!?" "Can't go one day in this country without some magic bullshit happening—"
Bianca: I think I'm getting better at shadow travel!
Nico: Yup, definitely...!
Hazel: *Throwing up in a bush because she "rode" with Bianca and her "driving" was god awful*
Bianca: *Blood covered* Hey guys the monsters bleed here :D!
Ancient Greeks: *Burning a fuckton of offerings to Hades*
Persephone: *Was/is mad but Hades is panicking so bad it's making her question if he was actually unfaithful*
Persephone: Darling...You Alright—?
Hades: The math isn't mathing beloved! The math isn't mathiiiing (;—;)!
