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.

Percy's POV Part I

Ever get the feeling there's something you're forgetting even though you're in the place that should jog whatever you're forgetting? Well that's what I been feeling since Annabeth and I started following the River of Phlegethon.

I mean, I know Tartarus is the home of every destroyed monster until they're reformed, and of course the spirit Tartarus itself. But I can't shake this feeling that there's something else down here we're forgetting. A nagging feeling that other than Tartarus there was something else more powerful than the monsters we might face.

Anyways, Annabeth and I have been following the River Phlegethon, stumbling over the glassy black terrain, jumping crevices, and hiding behind rocks when the vampire girls slowed in front of us.

Even with Myrmekes gunk masking our demigod scents, it was tricky to stay far enough to avoid getting spotted but close enough to keep Kelli and her comrades in view through the dark hazy air. The heat from the river baked my skin. Every breath was like inhaling sulfur-scented fiberglass. When we need water, I poured some out of my thermos, but when we need a healing drink, we drink liquid fire.

At least Annabeth's ankle seemed to have healed since we fell into Tartarus. She still had a slight limp, but she wasn't showing signs of pain. Her various cuts and scrapes had faded (which made me wish I can transfer the invulnerability of the Achilles Curse to her without giving her the whole curse itself). She tied her blond hair was back with a strip of denim torn from her pant leg, her dagger strapped to her belt, backpack strapped to her back, and in the fiery light of the river, her gray eyes flickered. Despite being beat-up, sooty, and dressed like a homeless person, she looked great to me.

So what if we were in Tartarus? So what if we stood a slim chance of surviving? I was so glad that we were together, I had the ridiculous urge to smile.

As for myself, my clothes looked like I'd been through a hurricane of broken glass. I was thirty hungry, and scarred out of my mind (you have to be crazy not to be scared while in the monsters' home turf), but other than that, I'm solid thanks to the River Phlegethon. After drinking its water, I'm not as tired as I thought I would be after summoning that water blast to save Annabeth and me earlier.

Time was impossible to judge down here. Annabeth agreed not to bring out Daedalus laptop unless we absolutely needed too after Arachne tried to attack her. I doubt it attracted monsters if we used it (I doubt Daedalus designed such an advance laptop without having some kind of magical protection that keeps monsters from finding a demigod that uses it), but we didn't want to take any chances.

We trudged along, following the river as it cut through the harsh landscape. Fortunately, the empousai weren't exactly speed walkers. The shuffled on their mismatched bronze and donkey legs, hissing and fighting with each other, apparently in no hurry to reach the Doors of Death.

Once, the demons sped up in excitement and swarmed something that looked like a beached carcass on the riverbank. I couldn't tell what it was—remains of a monster that didn't turn to dust? An animal of some kind? The empousai attacked it with relish.

When the demons moved up, Annabeth and I reached the spot and found nothing left except a few splintered bones and glistening stains drying in the heat of the river. I had no doubt the empousai would devour demigods with the same gusto.

"Come on." I led Annabeth gently away from the scene. "We don't want to lose them."

As we walked, I started hoping things would get better for Annabeth and me once this quest is over. I mean, what else does the fates have plan for us? It can't get any more dangerous than this, right?

I remembered the vision I saw when the Fates cut Luke's life line after he died. It showed that I would live a full life. I still had hopes that it would happen, that I'll live a full life with Annabeth, hopefully in New Rome after the rift is healed between Greeks and Romans, only leaving to visit our relatives, and from time to time Camp Half-Blood.

After a few more miles, the empousai disappeared over a ridge. When Annabeth and I caught up, we found ourselves at the edge of another massive cliff. The River Phlegethon spilled over the side in jagged tiers of fiery waterfalls, the demon ladies were picking their way down the cliff, jumping from ledge to ledge like a mountain goat.

There was no way we could catch up with them now. Not from climbing down the cliff I mean. Not that we had much to look forward too once we do.

The landscape below us was a bleak, ash-gray plain bristling with black trees, like insect hair. The ground was pocked with blisters. Every once in a while, a bubble would swell and burst, disgorging a monster with a larva from an egg.

I read about a lot of monsters in Hal's book and learn about them in monster fighting class, but I never heard of one like that.

Above us wasn't much better. There were dark winged shapes spiraled in and out of the blood red clouds and something told me those weren't the servants of Hades known as the Furies.

I looked down and saw all newly formed monsters were crawling and hobbling in the same direction—toward a bank of black fog that swallowed the horizon like a storm front. The Phlegethon flowed in the same direction until about halfway across the plain, where it met another river of black water. The two flowed as one toward the black fog.

The longer I looked into that storm of darkness, the less I wanted to go there and the more I get this suspicious feeling that I'm forgetting something crucial about Tartarus. But if the Doors of Death were in that direction, it was our only chance to get home.

"We could try jumping and use my thermos to soften our landing," I suggested.

"We could, but considering we don't know what's in the dark fog, we should conserve our strength," Annabeth replied.

"Then we climb," I responded.

I couldn't see the empousai below us anymore. It seemed like they disappeared behind one of the ridges, but that didn't matter anymore. We know where we need to go—into the dark horizon with a bunch of other monsters. I was just brimming with enthusiasm for that.
