The different prophecies

Throughout Percy's journeys, each quest begins with a prophecy, a prophecy that will help the demigods throughout their adventure, giving them clues. Here are a list of prophecies that Percy has received.

Percy Jackson and the Lighting Thief

You shall go west, and face the god who has turned,

You shall find what was stolen, and see it safely returned,

You shall be betrayed by one who calls you a friend,

And you shall fail to save what matters most, in the end.

Percy Jackson and the Sea of Monsters

You shall sail the iron ship with warriors of bone,

You shall find what you seek and make it your own,

But despair for your life entombed within stone,

And fail without friends, to fly home alone.

Percy Jackson and the Titan's curse

Five shall go west to the goddess in chains,

One shall be lost in the land without rain,

The bane of Olympus shows the trail,

Campers and Hunters combined prevail,

The Titan's curse must one withstand,

And one shall perish by a parent's hand.

Percy Jackson and the battle of the Labyrinth

You shall delve in the darkness of the endless maze,

The dead, the traitor, and the lost one raise.

You shall rise or fall by the ghost king's hand,

The Child of Athena's final stand.

Destroy with a hero's final breath,

And lose a love to worse than death.

Not only Percy received prophecies, but as did Jason Grace in his time at Camp Half-blood. He had many adventures, which involved going on quests with his friends, Leo Valdez and Piper McLean. (The Heroes of Olympus)

The Lost hero

Child of Lightning, beware the earth,

The giants' revenge the seven shall birth,

The forge and dove shall break the cage,

And death unleash, through Hera's rage.

The Son of Neptune

"Go to Alaska.

Find Thanatos and free him.

Come back by sundown on June twenty-fourth or die."

The Mark Of Athena

"Wisdom’s daughter walks alone,

The Mark of Athena burns through Rome.

Twins snuff out the angel's breath,

Who holds the key to endless death.

Giants' bane stands gold and pale,

Won through pain from a woven jail."

Even so, there are still many prophecies that are not specified, these are called the 'Great Prophecies'.

A Half-Blood of the eldest gods,

Shall reach sixteen against all odds

And see the world in endless sleep

The hero's soul, cursed blade shall reap

A single choice shall end his days

Olympus to preserve or raze

Prophecy of the seven

Seven half-bloods shall answer the call.

To storm or fire, the world must fall.

An oath to keep with a final breath,

And foes bear arms to the Doors of Death.
