Satyrs, also known as Fauns by Romans, are creatures with the upper body of a man and the lower body of a goat complete with hairy goat legs and hooves, as well as goat horns, and the pointed ears of a goat. When in public, they tend to be clumsy, for they have to wear fake feet and hats (such as Grover's rasta cap) so that the sound or appearance of their hooves or horns won't draw unwanted attention from mortals.
Satyrs, alongside nymphs, are nature spirits that were created when Ouranos' blood spilled on fertile soil after he was murdered by his son Kronos. In Greek mythology, they were minor Gods of the forest- like Gods, they never die, but simply transform in a weaker state into a plant. They work for Camp Half-Blood and go out into the world to search for Greek demigods. While searching, they wear disguises, such as fake feet and hats that hide their horns. It is possible that the Mist cannot hide all of a satyr's features however, as a flight attendant of Tristan McLean's saw Gleeson Hedge's hoof, but passed it off as just seeing things as well as Percy Jackson giving Grover Underwood his shoes in The Lightning Thief so that the life guards wouldn't see Grover's hooves. Many went to search for Pan, theIn Greek ancient god of the Wild, until he faded. Most of those satyrs were lured to Polyphemus' Island because of the overpowering scent of the Golden Fleece during their search for Pan and then eaten. Others, such as Ferdinand, who was turned to stone by Medusa, were attracted to other monsters for reasons unexplained. Satyrs also worship the god Dionysus. They also seem to appreciate the goddess Artemis as she is "so into nature", as stated by Grover.The most commonly known satyr is Grover Underwood, the best friend and protector of Percy. Grover was sent to search for demigods and found Percy, and later became the best friend of Percy. He also had to make sure that Percy stayed out of trouble, which was hard because Percy was a child of Poseidon, and due to children of the Big Three having a stronger scent, it caused him to attract more monsters.
Many satyrs go to Camp Half-Blood to become a Searcher. A role of which they will usually conduct a search of Pan, the god of the Wild. Long ago, Pan disappeared, as the modern civilization was tearing apart the wild. Afterwards, in The Battle of the Labyrinth, Percy, Grover, Tyson, Annabeth, Nico, and Rachel find Pan in a nature paradise where Pan fades and soon he gives his role of Lord of the Wild to Grover.
Fauns are the Roman form of satyrs. At Camp Jupiter, fauns tend to be content with lounging around and begging for money (such as when Don the faun asked Percy if he had any spare change) and are used for amusement purposes. With the exception of the fauns acting as nurses following the Battle at Camp Jupiter they are useless. The fauns of Camp Jupiter are the complete opposite of satyrs at Camp Half-Blood.

- Oddly, in the myths, satyrs are described as creatures with wild desires, making the choice of them to collect young demigods, particularly girls, slightly questionable in nature.
- The Roman term for satyr is faun, probably derived from the faunus, which happens to be the Roman counterpart of Pan.
- At Camp Half-Blood, satyrs sit at the Dionysus table for meals, along with his children and Dionysus himself.
- In some Roman myths, fauns were thought to have a large poetic imagination.
- In Camp Jupiter, fauns are treated as annoying beggars while in Camp Half-Blood, they are more important as they are Keepers and Searchers, which adds more demigods to their camp.
- They despise being underground, as everything smells the same, therefore making it harder for them to smell danger.
- There are no female satyrs in the series, as the female equivalent of a satyr is a Nymph.
- Although, in some myths, female counterparts are called satyresses.
- The earliest depictions of satyrs portray them as having full human bodies, and the tails and ears of horses or other equine creatures. Though these kinds of satyrs are sometimes referred to as Sileni, being descended from Silenus, while the goat-legged satyrs are mentioned as Panes or Paneides, the children of Pan and brothers to Silenus, which the satyrs in the books could be as they are exceedingly loyal to Pan and willing to search for him at all costs.
