Here are the notes:

Rachel and Chiron contact to tell them the Romans are going to attack, and they need help, fast, or both camps will die fighting themselves. Meanwhile, Percy and Annabeth are still falling into Tartarus.

The 6 and Nico must detour back to Camp Half-Blood.

Jason has a dream about an exchange between Gaia and Octavian, and now knows that the Gaia is controlling the Romans through him so it will eventually lead to their own destruction.

They get to camp, and Chiron decides no matter what they do, the Romans will still attack.

Nico comes up with a plan to do with the Athena Parthenos, thinking it will distract the Romans and stop the feud as the legend goes, or at least let them kill Octavian or talk to Reyna.

Rachel gets a vision and prophecy:

The fallen will be forced to fly

All may be lost at the battle cry

The earth depends on the fatal flaw

And she herself will close the doors

(I know it's not that, like, mysterious and stuff. But it rhymes!)

Percy and Annabeth arrive in Tartarus, 3 days early, courtesy of Gaia (this has happened already in the story)

They manage to survive for one, when Annabeth tries to get Arachne's help, but after that Annabeth blacks out for 2 days.

When Annabeth is conscious again, she is mentally unstable as a result of exhaustion and the mind games in Tartarus. However, she realizes she is no longer in Tartarus, and neither is Percy, but instead in some sacred place in mythology (which I didn't research).

A giant (sorry, I didn't know which) says they are going to be sacrificed to Gaia.

It tortures Annabeth until Percy willingly gives in to save her, saying he will be sacrificed to Gaia if Annabeth is left alone. They swear on the river Styx. (Percy's fatal flaw. See?)

Back at Camp Half-Blood, the plan goes well. They manage to imprison Octavian, and the Romans and Greeks finally unite for the first time in centuries. However, the Argo II is destroyed in battle. (I'm not sure about this). It is Day 8.

They have to assist a plane to travel to Epirus, with a small army in tow, and when they get to the House of Hades, a mysterious being is there. Nico feels that the being is very familiar (have you guys guessed what it is? Not that hard).

He sends Nico on a quest to find a random escaped soul (I don't know which. You can choose), saying that if he is successful, he will help them close the Doors and help Percy and Annabeth. Since they still think the two are falling, they quickly agree.

(This is Nico's quest, which I don't know what happens in. My idea of the ending was a bit blurry).

When Nico succeeds in bringing back the soul, the thing says it wants Hazel, because she too is an escaped soul. They don't let it take Hazel, but manage find out that Percy and Annabeth are no longer in Tartarus.

Nico realizes the being is indeed Tartarus, and they fight but Tartarus is outnumbered, so they manage to imprison Tartarus with the help of Athena/Minerva, who wants them to help her daughter (she has now recovered from her…er, breakdown since the Greeks and Romans have united because of the Athena Parthenos)

Percy is about to be sacrificed to Gaia when the 6 and Nico turn up.

They kill the giant (this time it is Poseidon who helps them and sends a tsunami to sweep it out to sea or something) and rescue Percy and Annabeth, who are both in very bad shape.

All of them flee from the place, back to Epirus to finally close the doors, but they have no idea how.

They bargain with Tartarus and he agrees to close the doors for themfrom the other side, and though no one trusts him they must.

The Doors are closed.

Gaia speaks to them, telling them that it is all part of her plan that this happens.

The 7 are reunited but left with many questions and still need to fully defeat Gaia, but Annabeth and Percy are in terrible condition.

THE END.

The Prophecy

The fallen will be forced to fly (Percy and Annabeth are the fallen, they are being forced to leave Tartarus despite how they haven't closed the doors, to be sacrifices for Gaia)

All may be lost at the battle cry (The Romans against the Greeks, the Romans have started a battle and Octavion is convinced joining Gaia is better as then they would we safe (he was sent a vision by some old god on Gaia's side), if the six don't get to Camp Half-Blood and stop them in time and the Romans win the battle, the Romans will join the Greeks and destroy camp. Gaia is convinced the Greeks will not win because they are outnumbered, most likely they will fight each other to death).

The earth depends on the fatal flaw (Gaia depends on Percy's loyalty to his friends to be her sacrifice)

And she herself will close the doors. (Gaia acted through Tartarus to close the doors)

Author notes:

A little explanation on the story front: the other POV was to be Jason, and the reason Tartarus wanted Hazel was so she could be Gaia's sacrifice (in case you haven't figured that out already).

OK. That's it guys. I'm sorry I didn't end the story (I barely got started) and I know the story went really weird in Annabeth's POV. Also, parts of it don't make sense.
