"Percy, where are you?" asked Annabeth to thin air as she peaked inside his cabin. Not here where could he be? I KNOW he's not at the library, I checked the arena, hmmmmmmmmm. Then it hit her, Grover, duh why didn't I go to him first. Annabeth went over to the forest and found Grover and Percy playfully tussling at the forest border with each other while Juniper watched. "Percy, Chiron wants us at the Big House." Percy knew never to question when you get summoned but just to tick off Annabeth he asked "Well what does he want us for Wisegirl?" Annabeth getting exceedingly more ticked off by the second practically screamed "Well what do you think, a quest maybe!?" Percy knew he had won so he came along without acting up TOO much on the way.
"Your quest, if you decide to except it will be fraught with many dangers, including: Niemen Lion, Hellhounds, Furies, and last but not least Aphrodite." Both of us said the exact same thing simultaneously "HUH?" " Oh" said Chiron in his matter-of-fact voice "Aphrodite is on a rampage, something about you two not being together ." "Yet." Both Percy and I blushed from our necks up. "So will you except the quest Percy?" Percy still blushing just nodded.
"I am the spirit of Delphi, ask seeker." Percy simply stated "What is my fate?"
"You shall travel to Olympus on a chariot of sun"
"You'll consult with the rival of one"
"She'll tell you what you need for this quest"
"Up to your love is the rest"
The only line Percy really cared about was the last one, the answer is so simple anyone with a brain could answer it, it's Annabeth.
