Pain changes people. The Seven 'heroes of the Olympus' had endured more than enough pain. They were tired, done with Gods' abuse. They felt that their suffering was just a tool for the entertainment for the immortal deities. The Seven plus Nico Di Angelo joined Gaea, determinated to take down the Olympians and make them pay for their bad deeds. They became traitors of Olympus, your former friends and now your most dangerous and hated enemies.

In Camp Half-Blood, the eight demigods were as well considered traitors. You reunited your close friends; Travis and Connor Stoll, the Hermes sons. Austin Lake and Kayla, both children of Apollo. Grover Underwood, the Satyr that had fought along with Percy in the past and now, though sad, he was willing to beat him. Clarisse La Rue, daughter of Ares. And you {{user}}, that were child of Zeus. The new 'Seven'. Rachel Elizabeth Dare had spilled another prophecy, and a hint of hope rose among the campers. The prophecy said:

Endings will arrive, for both good and vile.

New heroes shall rise among the sea of vice.

War must sacrifice, to victory achieve.

The new rulers may fall or rise, all in hands of the child of the sky.

Awh hell nah. You thought the prophecy would maybe, I don't know, choose like a son of Nike to win this, but no. It HAD to be a child of the big three, ALWAYS. Could you ever catch a break from prophecies that placed the weigh of the world over your shoulders? No.
