Gorgon

Gorgons are the three terrifying sisters turned into monsters by Athena.
== Becoming Gorgons ==
Their parents are the sea deities Keto and Phorcys. The Grey Sisters and Echidna are their other sisters. Medusa was a fair maiden and a priestess of the goddess of Athena, which meant that she couldn't marry in order to devote all her energy to the goddess. When in the temple of Athena, Poseidon came down from Olympus and took notice of Medusa, who became her lover. Poseidon took Medusa to one of Athena's most sacred temples on a date. Stheno and Euryale helped their younger sister to enter the temple. However, Athena caught the couple in her most sacred temple and found out that Medusa was no longer a virgin. Knowing that she could not take anger upon a god directly, Athena directed her wrath towards Medusa and cursed her without warning, to forever become a monster with slithering serpents as hair and a gaze that could turn a man to stone. Her sisters, Stheno and Euryale, were turned into Gorgons as well for assisting their sister into the goddess' sacred temple. Eventually, Medusa started to create statues because she felt lonely after her sisters faded away.
== Spoils of War ==
Contrary to popular belief, only Medusa could turn people into stone by looking into people's eyes. She was killed by Perseus by cutting off her head, which he later used by Perseus to kill the sea monster Keto. Though their body parts weren't used as spoils of war; Stheno and Euryale leave behind vials of their blood instead. Athena received Medusa's head as a sacrifice from Perseus. She gave the head as a gift to her father Zeus, who used it to create his shield, Aegis, on oracular advise to win against the remaining Titans. He used the Aegis to defeat Aex (or Aix), who had a head as terrifying as her body was beautiful. Thalia Grace has a shield modelled after the Aegis, which usually causes enemies to be paralyzed or run away in terror.
== The Gorgons ==
=== Medusa ===
Medusa is the youngest and most famous of the gorgon. She is the only one with the power to turn her victims into stone, being the envy of Euryale. Medusa used to be the most beautiful of the sisters as well, which is the reason Poseidon noticed her. Medusa is the only gorgon that has appeared in the first series.
=== Euryale ===
Euryale is the middle among her gorgon sister. She is smarter than Stheno.
=== Stheno ===
Stheno is the oldest and the most vicious of the Gorgon sisters. She is rather naïve as well.
== Abilities ==
* Petrification: Medusa possesses a gaze so terrible, it can turn anyone to stone. It only works if they look directly into her eyes.
* Charmspeak: Medusa has the ability to persuade people to open their eyes with a soothing voice.
* Gorgon Blood: Blood from their right side can cure anything, but the blood from their left side is deadly.
* Control of Animals (limited): The Gorgons have living, venomous snakes for hair.
