List of characters in the Camp Half-Blood series
Rachel Elizabeth Dare - A clear-sighted mortal girl who is able to see through the Mist. She is first encountered by Percy during The Titan's Curse as he flees from the skeletons summoned by Atlas. After mistaking her for a monster and realizing she is human, Percy discovers that she can see through the mist. She leads the skeletons away from Percy. Rachel goes to the same school as Percy in "The Battle of the Labyrinth," realizing that the cheerleaders are actually empousai. In The Battle of the Labyrinth, she aids Annabeth and Percy by guiding them through the labyrinth to Daedalus's workshop. From there she, Percy, Annabeth, and Nico escape, only to enter again to locate Grover and Tyson. She is present at the deathbed of Lord Pan and, like the others, takes part of his essence within her. By throwing her hairbrush at Kronos, she provided enough of a distraction for Percy to escape the Titan Lord's time manipulation. It is hinted throughout the series that she harbors romantic feelings for Percy. In The Last Olympian, she begins having strange visions and becomes the new Oracle of Delphi after Hades's curse is lifted, under the guidance of Chiron and Apollo. Her first act as the Oracle is to deliver the Great Prophecy of the next generation of heroes.
