Clear Sight

Clear sight is the ability to see through the Mist, the force that hides the truth from most mortals. Some mortals are born with this gift. All demigods have this ability to some extent, but they can still be tricked. Some of the mortals with this ability have been candidates to host the Oracle of Delphi such as May Castellan and Rachel Elizabeth Dare.

Percy Jackson and the Olympians

The Lightning Thief

Sally Jackson shows signs that she can see through the Mist as she can see the Minotaur and Grover Underwood's goat legs. In St. Louis, there was also a little girl telling her mom "that boy is coming out of the river, and he's dry!" Also, the woman from the Gateway Arch is seen stunned as she tries to explain to the paramedics of a "fire-breathing chihuahua" and how the monster disappeared after a boy jumped from the hole.

The Sea of Monsters

Sally continues to show signs of seeing through the Mist, including the fact that she recognized Tyson as a Cyclops instead of a normal human. Even Percy, an extremely powerful demigod was tricked by this.

The Titan's Curse

When Percy Jackson is at the Hoover Dam, he slashes at Rachel Elizabeth Dare, who sees Riptide for what it is. She shows that she can see through the Mist by seeing the skeleton warriors for what they are and directing them away from Percy. Thalia Grace then explains to Percy that some mortals are born with the ability to see through the Mist, leading Percy to realize that his mother is the same way. Dr. Chase was also able to see through the Mist. An example of this is when he talked about the pegasi's wingspan compensating for the weight of the horse.

The Battle of the Labyrinth

Rachel Elizabeth Dare, a clear sighted mortal.

Rachel helps Percy by looking through the Mist. She then leads him and Annabeth Chase through the Labyrinth as part of their quest. Having realized that his mother could also see through the Mist, Percy asks her about it. Sally admits that its one of the things that drew Poseidon to her in the first place, but she states that her ability is currently lesser than it was when she was young.

The Demigod Files

The Stolen Chariot

A young girl is able to see Ares' War Chariot in its true form, but her mother can not. This could be because children have a more vast imagination but it also could be that she actually had the ability to see through the mist.

The Last Olympian

Rachel continues to help Percy. Sally Jackson wakes up from her sleep and is able to see the monsters and gods fighting each other in the Battle of Manhattan.

The Demigod Diaries

The Son of Magic

Mr. Claymore gains this ability by forcing to accept the possibility that monsters are real.

The Senior Year Adventures

Wrath of the Triple Goddess

A number of trick-or-treaters on Halloween are apparently clear sighted as they are able to see the manse through the Mist, the magical doorknobs and what Argus actually looks like. Argus gives them all candy and sends them off before the kids can ask too many questions.

The Trials of Apollo

The Tower of Nero

Leo Valdez tells Apollo that some of the homeless kids that he's teaching shop skills to can see through the Mist and see that Festus is actually a bronze dragon rather than a truck. Leo is shown to be excited about this fact.

Magnus Chase and the Gods of Asgard

The Hammer of Thor

Amir Fadlan gains this ability by opening his mind to the possibility that there is more to the universe.

The Nico di Angelo Adventures

The Court of the Dead

Will Solace's mother Naomi is revealed to be clear sighted, allowing her to see Hazel Levesque and the mystics trapped inside of Golden Gate Park such as Asterion.

Known Users

• Magicians
• All demigods and legacies (to a certain degree, as the Mist has been shown to repeatedly fool even the most experienced demigods).
  • Ariadne
• Marie Levesque
• Maria di Angelo
• May Castellan
• Sally Jackson
• Frederick Chase
• Dr. Howard Claymore
• Amir Fadlan
• Rachel Elizabeth Dare
• Naomi Solace
• Some mortal children can see through the Mist, as they are more open minded and have a much more vast imagination.

Trivia

• It is mentioned that not even the gods understand why some humans are born with the ability to see through the Mist.
• It is believed that children can see through the Mist because they are more open minded. However, most lose this ability as they get older.
• Frederick Chase, Amir Fadlan, and Mr. Claymore are the only known clear-sighted humans who are male.
• Sally Jackson mentioned that she cannot see through the Mist as well as she did when she was younger, suggesting that clear sight declines with age.
• There's an implication that Paul Blofis can at least partially see through the Mist, but not as greatly as Sally can as he initially didn't believe her when he was told that Percy is a demigod, until he meets Mrs. O'Leary. During the Battle of Manhattan, he kills a Scythian Dracaena and quickly hoped that it was a monster he killed (hinting that he was briefly fooled).
• Amir Fadlan and Mr. Claymore are the only known humans to gain the ability, as all other known users are born with it. This shows that it is possible to gain the ability as well.
• Estelle Blofis may also inherit the ability, as her mother has the ability. If confirmed, this may hint that Clear Sight is in fact genetic, similar to Frank Zhang's ancestral ability to shapeshift.
• As seen with May Castellan and Rachel Elizabeth Dare, clear-sighted mortals are chosen as the hosts for the spirit of the Oracle of Delphi, although Rachel showed some prophetic abilities in The Last Olympian even before taking on the Oracle's spirit.
• In the Disney+ series, clear-sighted mortals are referred to as "Seers".
• In The Court of the Dead, it's revealed that Will Solace's mother Naomi is clear sighted.
