A/N (I recommend reading this): I'm going to MAKE THIS CLEAR. Just like I mention on my bio page about every other fanfiction I done: I DON'T OWN THE PERCY JACKSON AND THE OLYMPIAN SERIES OR IT'S CHARACTERS as the rights goes to Rick Rioran. Also I suggest you guys start paying attention to the Author notes and my warnings that I left on EVERY chapter of EVERY story.

Sorry if this chapter is too much like the book.

Due to the limited number of characters posted, I'm forced to post only the names of the characters telling their tales in this story. When I get to the House of Hades and Blood of Olympus, I'll list off the first four characters listed in the order they tell their tales. I'll post the pairings if the two of the four characters listed are a pair. Other than that, the Pairings stay the same for this story.

Jason x Piper
Percy x Annabeth
Frank x Hazel

If you haven't figured it out, each of the members of the Prophecy of Seven practically has a position. Keep in mind in the original series Juno started this when she told Percy he was the glue that holds the group together, so I thought to give the rest a title. But no matter what title they have they still depend on each other. Titles will be added for some as the series continue

Jason: Leader of the Group
Piper: Peacekeeper
Leo: Mechanic, Admiral, and Seventh Wheel (by Nemesis)
Percy: Glue that holds everyone together
Hazel: Youngest (Her title will change further into this story).
Frank: Muscles
Annabeth: Battle Strategist and Consultant

Lastly I want to make clear that once 'The Tales of the Heroes of Olympus' is done I won't start immediately on 'The tales of...' version of the Trials of Apollo until that part of the Percy Jackson series is done. Just as I waited for the end of the Blood of Olympus to start 'The Tales of...' series. By waiting until that series ends, it might help me come up with something to add to it.

Warning: Certain ancient Greek names matches words use of foul language but no foul language was intentionally used. Also I dropped the '& the Olympians' in 'The Tales of the Son of Poseidon & the Olympians' as well as replaced the '&' with ':' in the short stories of that part of the series. So if you haven't read them yet read before reading this story as stuff that happened in them will be mentioned:

The Tales of the Son of Poseidon: the Early Adventures
The Tales of the Son of Poseidon: The Lightning Thief
The Tales of the Son of Poseidon: The Sea of Monsters
The Tales of the Son of Poseidon: The Titan's Curse
The Tales of the Son of Poseidon: The Magical Labyrinth
The Tales of the Son of Poseidon: the Stolen Chariot
The Tales of the Son of Poseidon: the Sword of Hades
The Tales of the Son of Poseidon: the Bronze Dragon
The Tales of the Son of Poseidon: The Last Olympian
The Tales of the Son of Poseidon: the Staff of Hermes
The Tales of the Heroes of Olympus: The Lost Hero
The Tales of the Heroes of Olympus: The Quest for Buford
The Tales of the Heroes of Olympus: The Son of Neptune
The Tales of the Heroes of Olympus: The Mark of Athena

Lastly, any one who wants to do a Demigods and Olympian reads story using 'The Tales of the Son of Poseidon' is allowed as long as you inform me about it.

Full Summary of this chapter: Separated from their friends, Percy and Annabeth must travel through Tartarus against all odds to find the Doors of Death while facing monsters, Titans, and all sorts of enemies of the gods with a help of an amnesiac Titan and Rogue Giant. Meanwhile Argo II must find away to make it to the house of Hades is at while facing all sorts of new trouble and making new allies along the way. This is the Tales of the Prophecy of Seven.

Leo's POV Part II

I had designed the mess hall's walls to show real-scenes from Camp Half-Blood. At first I thought that was a pretty awesome idea, and that maybe after a day in Camp Jupiter I can have it show scenes of that for Frank and Hazel. But now I'm not sure.

The scenes from back home—the campfire sing-alongs, dinners at the pavilion, volleyball games outside the Big House—just seemed to make my friends sad. The farther we got from Long Island, the worse it got. The time zones kept changing, making me feel the distance every time I look at the walls. Here in Italy, the sun had just come up. Back in Camp Half-Blood it was the middle of the night. Torches sputtered at the cabin doorways. Moonlight glittered on the waves of Long Island Sound. The beach was covered in footprints, as if a huge crowd just left.

Then I remember that yesterday—last night, whatever—had been the Fourth of July. We'd missed Camp Half-Blood's annual party at the beach with awesome fireworks prepared by my siblings in Cabin Nine.

I decided not to mention that to the crew, but I hoped our buddies back home had had a good celebration. They needed something to keep their spirits up, too.

I remembered the images I'd seen in my dream—the camp in ruins, littered with bodies; Octavian standing at the volleyball pit over Beckendorf and his girlfriend, and talking casually in Gaea's voice.

I stared down at my eggs and bacon. I really wish I could turn off the wall videos.

"So…" Jason said, "now that we're here…"

Ever since Percy fell into Tartarus and we had to remain in flight mode, Jason took the head chair. Although there were days he seem to sit in the second seat reserved for whoever of the two isn't leading at the moment, as if thinking we're about to return to the sea and Percy could take the pressure off his shoulders for once.

It actually been kind of weird at first when I think about it. At the beginning of the quest, whenever Percy took the head chair, Jason seem to can't wait to regain the seat. But now, after some kind of brotherly bonding those two did fighting the twin banes of Dionysus, it seems that Jason expected Percy to take the seat and didn't argue about it.

I glanced at the others around the table. Hazel was bleary-eyed, after being up all day and night. She seemed pale and slightly greener than usual when we're in the air, which I guess was from her shadow traveling lessons. Her curly cinnamon-colored hair was tied back in a bandanna, which gave her a commando look.

Next to her sat her boyfriend Frank Zhang, dressed in black workout pants and a Roman Tourist T-shirt that said CIAO! That we picked up during our 'try-to-Find-Hazel's-half-brother' version of a tour of Rome since Buford lost some of his dirty laundry back in the states (long story). Frank's old centurion badge was pinned to his shirt, despite the fact that the demigods on Argo II were now public enemy's one through seven back at Camp Jupiter. His grim expression just reinforced his unfortunate resemblance to a sumo wrestler.

Then there was the guy we spend the time touring around Rome to find: Hazel's half-brother Nico di Angelo. That kid gives me the freaky-deakies. I didn't say it out loud of course. I met his and Hazel's sister Bianca once and let's just say Nico is scarier than her.

He sat back in his leather aviator jacket, his black T-shirt and jeans, that wicked silver skull ring on his finger, a celestial bronze hunter's knife from Bianca strapped to his belt, and the Stygian sword at his side. His tufts of black hair stuck up in curls like baby bat wings. His eyes were sad and empty, as if he stared into the depths of Tartarus—which he had.

The only absent demigod that was on the ship was Piper, who was taking her turn at the helm with Coach Hedge, our satyr chaperone.

I wished Piper was here. She had a way of calming things down with that Aphrodite charm of hers (which is the reason she's our peacekeeper in the crew), and after last night's dream, I could use some calm.

On the other hand, it was probably a good she was above deck chaperoning our chaperone. Now that we were in the ancient lands, we had to be constantly on guard. I was nervous about letting Coach Hedge fly solo. The satyr was too trigger-happy, and the helm had plenty of bright, dangerous buttons that could cause the picturesque Italian villages below us go BOOM!

Unfortunately, I realized that Jason was still talking while I was zoned out.

"—the House of Hades," he was saying. "Nico?"

Nico sat forward. "I got in contact with the spirit of Odysseus last night."

He just tossed that line out there, like he was saying he got a text from a buddy.

"Odysseus—wasn't he that champion of Athena who took that great voyage home?" I asked.

Nico nodded, "He also adventured to the Underworld to talk to the dead, which is why I talked to him. He didn't tell me what I needed to know, but he did lead me to a former priest of Hecate who did," he said, "From what I gather, in ancient times, the House of Hades was a major site for Greek pilgrims. They would come to speak with the dead and honor their ancestors."

I frowned. "Sounds like Día de los Muertos. My Aunt Rosa took that stuff seriously."

I remembered being dragged by her to the local cemetery in Houston, where we'd clean up our relatives gravesites and put out offerings of lemonade, cookies, and fresh marigold. Aunt Rosa would force me to stay for a picnic, as if hanging out with dead people were good for my appetite.

Now that I think about it, one of those grave sites might have been Sammy's and I never even realized.

I quickly decided not to bring that up with Hazel and Frank here.

Thankfully they didn't push onto it as Frank grunted. "Chinese have that, too—ancestor worship, sweeping the graves in the springtime. My grandmother use to bring me along so I could get in touch with my ancestry." He glanced at me. "Your Aunt Rosa would've gotten along with my Grandmother."

That was a terrifying thought—my aunt and Frank's grandmother meeting and talking about worshipping ancestors.

"Yeah," I said. "I'm sure they would've been best buds."

Nico clear his throat. "A lot of cultures have seasonal traditions of the dead, but the House of Hades was open year round. Pilgrims could actually speak to the ghosts. In Greek, the place was called the Necromanteion, the Oracle of the Dead. You'd work your way through different levels of tunnels, leaving offerings and drinking special potions."

"I hope it's like the ones that healed Piper's dad's mind and not like the ones that killed Medea," I said.

"Most likely the first one," Jason replied, "Nico, go on."

"The pilgrims believed that each level of the temple brought you closer to the Underworld, until the dead would appear before you. If they were pleased with your offerings, they would answer your questions, maybe even tell you the future. If not, they got nothing or worse go insane or die after leaving the tunnels. Others possibly lost their way in the tunnels and were never."

"And you got that from the priest of Hecate," Frank said.

Nico nodded. "I also asked him to confirm what Hecate told Hazel last night about Hecate helping the gods in the previous giant war since…"

Nico trailed off but we got the idea. Percy and Annabeth are normally the most informed people we can turn to when it comes to needing info about the ancient stories.

"Anyways, in the first war with the giants, Hecate fought for the gods," Nico continued. "She slew one of the giants—one who'd been designed as the anti-Hecate."

"I thought Gaea wanted to replace the Olympians?" Frank asked. "Why would she make an anti-Hecate?"

"Gaea didn't create giants target every specific Olympians," Jason replied. "After all, Hera doesn't have a giant bane."

Nico nodded. "But for the ones she did left out, she created giants to go after ones she saw as a threat like at the time Hecate and the Fates."

"Wait, there's an Anti-Fates?" I asked. "What do they do? Go against destiny or something?"

Jason shot me a look like: Enough, Leo.

"So who is the anti Hecate?" he asked.

"A guy name Clytius," Nico replied.

"Dark dude," I guessed, "Wrapped in shadows."

Hazel turned toward me, her gold eyes narrowing. "Leo, how did you know that?"

"I kind of had a dream."

No one looked surprised. Most demigods had vivid nightmares about what was going on in the world.

My friends paid close attention as I explained. I tried not to look at the wall images of Camp Half-Blood as I described the place in ruins. I told them about the giant, and the strange woman on Half-Blood Hi, offering him a multiple-choice death.

Jason pushed away his plate of pancakes. "So the giant Clytius. I supposed he'll be waiting for us, guarding the doors of death.

Frank rolled up one of the pancakes and started munching—not a guy to let impending death stand in the way of a hearty breakfast. "And the woman in Leo's dream?"

"She's my problem," Hazel passed a diamond between her fingers in a sleight of hand. "Hecate mention a formidable enemy in the House of Hades—a witch who couldn't be defeated except by me by learning how to use magic."

"Do you know magic?" I asked.

"Not yet." Hazel said, "It's kind of difficult to learn on my own since the only other person who knew how to use the Mist is—is Percy."

Well that sunk in hard. My best guess is that if Percy and Annabeth didn't fall into Tartarus, he would have had to fight this mystery person, but because he did the job is put on Hazel's shoulders.

"Any idea who she is?" I asked.

Hazel shook her head. "Only that…" she glanced at Nico, and some sort of silent argument happened between them. I got the feeling that the two of them had had private conversation about the House of Hades, and they weren't sharing all the details. "Only that she won't be easy to beat."

"But there is some good news," Nico said. "The ghost I talked to explained how Hecate defeated Clytius in the first war. She used her torches to set his hair on fire. He burned to death. In other words, fire is his weakness."

I ended up wishing I wasn't the fire guy, because the moment Nico said that everyone turned to me. Normally I'm into this kind of attention, but after last night dream, I wished they didn't look at my direction.

Even Jason was nodding encouragingly to me, like this was great news—like he expected me to walk up to a towering mass of darkness, shoot a few fireballs, and solve all our problems. I didn't want to bring him down, but I could still hear Gaea's voice: He is the void that consumes all magic, the cold that consumes all fire, the silence that consumes all speech.

Maybe I should bring some Greek fire with me when I face this giant. At least with that I might stand a chance since that stuff is stronger than any fire attack I can produce.

"It's a good lead," Jason said. "At least we know how to kill this giant. And this sorceress… well, if Hecate believes Hazel can defeat her, then so do I."

Hazel dropped her eyes. "Now we just have to reach the House of Hades, battle our way through Gaea's forces—"

"Plus a bunch of ghost," Nico added grimly. "The spirits in that temple may not be friendly."

"—and find the Doors of Death," Hazel continued. "Assuming we can somehow arrive at the same time as Percy and Annabeth and rescue them."

Frank swallowed a bite of pancake. "We can do it. We have to."

I admired the big guy's optimism. I wished he shared it.

"So, with this detour," I said. "I'm estimating four or five days to arrive at Epirus, assuming no delays for, you know, monster attacks and stuff."

Jason smiled sourly. "Yeah. Those never happened."

I looked at Hazel. "Hecate told you that Gaea as planning her big Wake Up party on August first, right? The Feast of Whatever?"

"Spes," Hazel said. "The goddess of hope."

Jason turned his fork. "Theoretically, that leaves us enough time. It's only July fifth. We should be able to close the Doors of Death, then find the giants' HQ and stop them from waking Gaea before August first."

"Theoretically," Hazel agreed. "But I'd still like to know how we make our way through the House of Hades without going insane or dying."

Nobody volunteered any ideas.

Frank set down his pancake roll like it suddenly didn't taste good. "It's July fifth. Oh, jeez, I hadn't thought of that… My grandmother—she always told me that seven was an unlucky number."

"I thought it was a lucky number," I responded.

"Not to the Chinese," Frank explained, "It was a ghost number. She didn't like it when I told her there would be seven demigods on our quest. And July is the seventh month. Back in China, in the old days, people called the seventh month the ghost month. That's when the spirit world and the human world were closest. The living and the dead could go back and forth. Please tell me it's a coincidence we're searching for the Doors of Death during the ghost month."

No one spoke, not even me.

I wanted to think that an old Chinese belief couldn't have anything to do with the Romans and the Greeks. I thought they were totally different. But Frank's existence was proof that the cultures were tied together. The Zhang family went all the way back to Ancient Greece. They'd found their way through Rome and China and finally Canada.

Also I kept thinking about my meeting with the revenge goddess Nemesis at the Great Sat Lake. Nemesis had called me the seventh wheel, the odd man out of the quest. She didn't mean seventh as in ghost, did she?

Jason pressed his hands against the arms of his chair. "Let's focus on the things we can deal with. We're getting close to Bologna. Maybe we'll get more answers once we find these dwarfs that Hecate—"

The ship lurched as if it had hit an iceberg. My breakfast plate slid across the table. Nico fell backward out of his chair and banged his head against the sideboard. He collapsed on the floor with a dozen magic goblets and platters crashing down on top of him.

"Nico!" Hazel ran to help him.

"What—?" Frank tried to stand, but the ship pitched in the other direction. He stumbled into the table and went face first into my plate of scramble eggs.

If it wasn't for my concern of why the ship was doing this, I would be laughing right now.

"Look!" Jason pointed to the walls. The images of Camp Half-Blood were flickering and changing.

"Not possible," I responded. "Those walls should only show scenes from Camp Half-Blood."

Yet it was changing scenes as a huge, distorted face filled the entire port-side wall: crooked yellow teeth, a scraggly red beard, a warty nose, and two mismatched eyes—one much larger and higher than the other. The face seemed to be trying to eat its way into the room.

The other walls flickered, showing scenes from above deck. Piper stood at the helm, but something was obviously wrong. She was wrapped up in duct tape with her arms and legs bound to the control console and her mouth gagged.

At the mainmast, Coach Hedge was similarly bound and gagged, while a bizarre-looking creature—some sort of gnome/chimpanzee combo creature with poor fashion sense—dancing around him, doing the coach's hair in tiny pigtails with pink rubber bands, which really doesn't look good on that guy.

On the port-side wall, the huge ugly face receded so that I could see the entire creature—that looked like the one on Coach Hedge only wearing crazier clothes. He started leaping around the deck, stuffing things in a burlap bag—Piper's dagger, my Wii Controllers, the Myrmekes gunk I had stashed away in the control room in case I need them but can't get to them (how did he find it? Not even Hedge knew where I kept it). Then he pried the Archimedes sphere out of the command console."

"No!" I yelled.

"Uhhh," Nico groaned from the floor.

"Piper!" Jason cried.

"Monkey!" Frank yelled.

"Not monkeys," Hazel grumbled. "I think those are dwarfs."

"They just stole my stuff! Not cool!" I yelled as I ran for the stairs.
