Hello to all of my amazing readers! Thank you for the new views, follows, and favorites!

In this chapter I added Princess of Flames's OC character. (Hope I wrote her in the way you wanted! If not, tell me and I'll change it for future chapters! :))

ENJOY!

Disclaimer: I don't own Percy Jackson or his characters. Do I look like Rick Riorian? *empty silence*exactly! SILENCE WILL FALL WHEN THE QUESTION IS ASKED! (I don't own Doctor Who either)

Chapter 4:

Calypso's POV

"Ok. So, what's the plan?" Piper asks.

"Who are you?" I ask a girl that I don't know, interrupting Percy's response.

She has wavy red hair and bright green eyes. And she was looking at Leo. I decided that if she keeps looking at him I don't like her. And I'll turn her into something. Maybe whatever her parent's symbol is. She can be a mascot.

"Julia." she answers, still looking at Leo. I glance at Leo and he is completely ignoring her. He let's go of my hand and puts his hand around my shoulders. I smile realizing that means that means he either is ignoring her or doesn't notice her.

"I'm Calypso." I answer.

"The Calypso? The Titan's daughter?" Julia asks.

"Yes." I answer, smirking.

She looks down and I lean into Leo.

"Anyways, guys, I think we should figure out where Thalia would be." Percy says.

"I can check the Underworld, see if Hades knows anything. And check in with Thanatos in case…you know…" Nico says. His sentence hangs in the air for a while until Jason says, "You're right. Check there. Hazel, go with him."

Hazel nods.

"I'm going to go up and use the winds so I can get an aerial view, see if I can see her or anything helpful." Jason says.

"Beauty Queen, Calypso, and I can look around area." Leo volunteers.

"Annabeth, Julia, and me can go in the other direction." Percy adds.

"Annabeth, Julia, and I can go in the other direction, Seaweed Brain." Annabeth corrects.

Percy looks down in fake shame.

"What can I do?" Frank asks.

"You're the praetor. It's up to you, man." Jason answers.

"I'll help Leo, Piper, and Calypso." he decides.

Leo nods. Hazel whispers something to him and he nods. "I will. Promise." he says. He will what? Hm…

"Clarisse, Chris—go with Percy, Annabeth, and Julia." someone says from behind us. I turn around and see the oracle, Rachel, standing behind us.

"How did you know we would be here?" Percy asks. Annabeth is definitely on to something.

"I'm the oracle, Percy. Remember?" Rachel asks.

"Right…" he mutters.

"Anyways, I won't tell Chiron. But Chris, Clarisse—go with them: South. Leo, Calypso, Piper: go East; towards Montauk. Travis, Connor-go North. Jason, when you're up in the air, go everywhere. Make sure to go West so you can get everywhere the people on the ground, and underground, can't." Rachel instructs.

Everyone agrees. We all say goodbye to the mysterious red-headed oracle and go our separate ways. I take Leo's hand as we walk.

"Ok. Look out for anything helpful, monsters, and most of all—Thalia." Frank says.

"Hey, Frank, we actually agree on something!" Leo says enthusiastically

Frank laughs. I kiss Leo's cheek, still happy he kept his promise and came back.

About an hour of us just talking and walking around the area Piper stops us and says, "Frank—turn into something sneaky and strong."

Jason's POV

I start flying around the area and, sadly, I'm alone. This means I have one person to talk to and I don't really like talking to that person: myself. Great.

The first thing that runs through my head: What did Thalia do?

Thalia could've done a lot of things to get herself in trouble. Liked a boy, got into a fight with another Hunter, killed someone's monster pet, accidentally attacked a wolf, killed a monster that someone else got dibs on, even just used someone else's bow. Who knows? But the problem with all of those: Artemis. All of them have to do with Artemis. Thalia, being a Hunter, would most likely get in trouble with Artemis of another Hunter. But Artemis doesn't know where she is! Or so she said…her eyes had a flash of something I'm not sure of. She has me curious. I'm starting to wonder if Artemis knows more than what she's saying. But if she did, then why did she lie? So, she can't know…right? Next thought: what could I have done to prevent it? Answer 1: anything. I could have helped her. I could've contacted her more. She's my sister; I could have helped her somehow. Answer 2: nothing. I couldn't have stopped her, knowing Thalia. Assuming it what she did she did willingly… 3: I could have—wait. What's that? I know I saw something move.

I fly down and look around. Nothing. There's nothing here…maybe it's just my—ah!

My thoughts are interrupted by I get tackled from behind. Stupid thoughts…you made my let my guard down. And now look! I'm getting tackled!

I flip my coin and get my sword. I turn around and push the mysterious person away. I look and see it's a girl, around15with long dark brown hair, like goes down to her knees long, in a…what did Lacy say it was called the other day when she put Piper's hair like that…a…um…a French braid. That's what she called it. I don't see a difference between a French braid and a regular braid but I'm a guy so that's a good thing. She has caramel eyes, a little brighter than Calypso's hair. She has a scar running across the right side of her face.

"Who are you?" I ask, getting ready for an attack. She takes out two fans that remind me of the ones you get at an arcade with enough tickets that break after a day.

"Why should I tell you?" she asks.

"I'd like to know why you tackled me. I'm just looking for my sister. What are you? Demigod?" I ask.

"Rosalia Starling. Daughter of Hera." she answers.

"Jason Grace. Son of Jupiter." I reply and as if on cue, I hear thunder.

"A Roman demigod?"

"That's old news. Stay with the program." I hear another voice say from behind me. I smirk, recognizing the voice immediately: Percy.

"Hey, Percy." I greet, not turning around.

"We're here too, Grace." I hear Clarisse say.

"Hey guys. Come to join the party?" I ask.

The girl, Rosalia, sighs. "Now, can we just get this over with? I have a schedule I plan to keep." she snaps.

"We don't want to fight. Now-why did you attack my friend?"

"I'm trying to get to the underworld. I'm not in a very good mood and when you see a demigod fall out of the sky you normally assume they are a monster." Rosalia says, putting away her fans.

I put away my coin.

"Why do you want to go to the Underworld?" Chris asks.

"I can answer that. I'm assuming this since you want to go to the Underworld, not Tartarus-not a recommended idea-you want to find something there. Based on the scar on your face it's a monster. That basically narrows it down to a hellhound. So, you want to go to the Underworld to kill the hellhound that scratched your face? In, what, the Giant War? Gaea controlled them and I'm betting they went back to the underworld after we put Gaea back to sleep, so, you want to kill the one that left you with that scar. Annabeth Chase, by the way, daughter of Athena." Annabeth says.

Rosalia nods.

"Ok, well, good luck with that…I guess…but have you seen a girl with black spiky hair? Blue eyes; like mine? Wearing leather?" I ask.

"Yeah, she went that way. Said she was going to Hades' Palace." Rosalia says, pointing to the West.

"Ok. Do you want to come with us? We're good friends with a son of Hades, maybe he can find the hellhound or get Hades to make it up to you. Well, they are." Julia offers.

She considers it. "Sure."

"Ok. I'll go find the others and then I'll meet you back here." I tell them, controlling the winds and flying up.

Percy's POV

The others finally arrive and we follow where Rosalia is guiding us, which could be very stupid.

"Sorry about trying to kill you." Rosalia apologizes to Jason.

"Um…thanks…? I think…" he answers uncertainly.

"I just…sometimes I can get a little over aggressive…but I am actually very nice." she promises.

We just talk nonsense for what feels like hours while we walk until Rosalia suddenly shouts, "THERE! THAT'S THE ENTRANCE! THAT'S WHERE THALIA SAID SHE WAS GOING TO GO IN!"

She points at a giant boulder. I focus for a minute, thinking the Mist might be playing tricks, and see a door. An actual door to the Underworld. In a rock. Get's more creative every time we find an entrance to somewhere…

"Let's go." Annabeth says, grabbing my hand. Then we walk straight into the Underworld.

What did you guys think?

Next chapter is going to be in the Underworld

What happened to Thalia?

When will we discover Lilith's Plan?

The OC offer still applies, by the way!

HOPE YOU ALL LIKED IT!

Love,
