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.
== 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
* 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.
* 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 so, 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.
