AN: This is roughly based off the headcannon by partdemigod. So you can thank him or her for the plot.
After the war, the Greek and Roman demigods had a celebration at Camp Half Blood.
Octavian was the only one who wasn't in a partying mood. He walked around the camp glumly, with a scowl on his face. That is, until Rachel introduced herself as the Oracle Of Delphi.
"This is absurd!" Octavian shouted "There can only be one augur! I say we have a battle to determine who that will be."
"First off, I'm an oracle." Said the redhead "But I'll kick your butt if you want me to."
They went to the arena, with both camps watching them. Octavian showed up wearing full battle armour, wielding a metre long sword. But when Rachel showed up with nothing but a blue plastic hairbrush, Percy literally had to be carried out of the building because he was laughing so hard.
