Of course not. I would not let my horses eat you, any more than I would let Akhlys kill you. Such fine prizes, I will kill myself!

–Nyx threatening Percy and Annabeth, in House of Hades.

Nyx is the Greek primordial goddess of the night and hellhounds. She carries the mantle of night in her chariot pulled by two dark horses Shade and Shadow, covering the world with darkness. Nyx is one of the first beings to have sprung from the void of Chaos. Her Roman form is Nox

History

Early life

Nyx was born directly from Chaos and Tartarus, two of the first protogenoi. She lives in Tartarus in the Mansion of Night, where she stays during the day and leaves during the night.

Nyx married her older brother Erebus (Darkness and Mist) and had many children with him. She also had children on her own, such as her daughter Hemera (Day), who left Tartarus when Nyx entered it, creating night and day.

On ancient times, Nyx, her daughter Hemera (whom she usually fights with), her son Aither, and the stars were the only constant company of Ouranos.

Trials of Heracles

Under Hera's orders, Nyx's son Hypnos put Zeus to sleep so the Olympian goddess could shower Hercules with misfortune without Zeus interfering. Zeus soon found out about Hypnos' involvement and furiously chased him. Hypnos quickly fled to his mother, who Zeus respected enough to hold his anger at bay.

The Heroes of Olympus

The House of Hades

Even before meeting with Nyx, nearly every creature in Tartarus shows a fear of her (even some Giants and Titans) to the point of only referring to her as Night. However, visiting Akhlys for the Death Mist requires Percy and Annabeth to pass close by Nyx's domain if they hope to escape from Tartarus and close the Doors of Death. Unfortunately, after Percy and Annabeth manage to gain the Death Mist she double crosses them though Percy and Annabeth manage to defeat her. However, they wander too close to Nyx's domain and she appears to kill them.

Encountering Percy and Annabeth

At first, Annabeth and Percy are too stunned to speak, both because of Nyx's intimidating entrance and because she is able to see them, even with the Death Mist. Percy also worries that the horses that pull her chariot will eat them. Nyx admits to them that she wouldn't allow her horses to do such a thing, as she wants to do it herself.

Annabeth uses Nyx's wording against her and tells Nyx not to kill herself. This causes Nyx enough confusion that Annabeth quickly takes charge of the situation and convinces Nyx that they are on a tour of Tartarus, but Nyx isn't part of it. This greatly offends Nyx as she gets more and more wrapped up in Annabeth's lie. When Annabeth claims it may be because Nyx isn't important enough and how they could meet some of Nyx's children instead, Nyx becomes furious and summons all her children, including Geras, Eris, and more minor gods and monsters, which are all the worst terrors in existence. As Percy and Annabeth prepare to try and take a picture, they mention the Doors of Death and Nyx tells them that the only way to reach it is by entering her home, the Mansion of Night. After hearing this, they agree to take a picture with her favorite child. After hearing this, her children begin to fight amongst themselves over who is the worst terror. When Nyx is blinded by darkness, Percy and Annabeth slip past her and run into her mansion.

Nyx and her children eventually recover and chase them into the Mansion of Night, but not before Percy jumps over the River Acheron with Annabeth on his back out the other side of the mansion, out of her grasp.

Personality

As the embodiment of Night, Nyx had a terrifying presence, temporarily stunning Percy and Annabeth into silence. Despite this, she is quite gullible, easily falling for the heroes' story. Though she is proud that most of her children are terrifying, Nyx is uncomfortable when someone asks her who is her favorite child.

Appearance

Nyx was described as a churning figure of ash and smoke, as big as the Athena Parthenos (which was 40 feet tall). Her face was hard to see except for the pinpoints of her eyes, which shone like quasars. When her wings beat, waves of darkness rolled over the cliffs. Her dress was void black, mixed with the colors of a space nebula as if galaxies were being born in her bodice.

Abilities

As one of the Protogenoi, Nyx is an extremely powerful deity feared by many Titans and Gods. Zeus himself feared her enough to retract all threats against her son Hypnos.

  • Circadian Manipulation: Nyx is capable of controlling the movement and rotation of planets, which enables her to change the flow of night and day.
  • Umbrakinesis: As the Protogenos of Night, Nyx has divine authority and absolute control over shadows and darkness.
    • Night Empowerment: Nyx becomes stronger at night or in dark places (e.g. Tartarus).
    • Darkness Generation: She can shoot solid bolts of darkness, surround enemies in pitch-black clouds of dark space, and solidify shadows into virtually impenetrable shields.
    • Shadow Travel: Nyx is able to travel anywhere she desired at incredible speeds through shadows.
    • Night Vision: Nyx is able to see clearly in even total darkness. However, even she cannot see in the absolute darkness created by the combined might of dozens of her children.
    • Umbrakinetic Vitakinesis: Nyx is able to heal minor injuries sustained by herself and others using darkness.
    • Shadow Camouflage: Nyx can use shadows to cover herself in darkness to become invisible.
  • Parthenogenesis: As shown in Percy Jackson's Greek Gods, Nyx managed to become pregnant with several divine children all by herself. 
  • Control of Nocturnal Animals: Nyx is able to control nocturnal animals, such as owls and bats.

Trivia

Shade and Shadow

  • At The House of Hades, Akhlys and Annabeth Chase refer to Nyx as being older than Gaea, thus making her the oldest daughter of Chaos. However, in Percy Jackson's Greek Gods, Nyx is said to have been created after the emergence of Gaea, Ouranos, Pontos, and Tartarus.
  • The International Astronomical Union named one of Pluto's moons Nix in honor of the Greek goddess. They spelled it with an "i" because there was already an asteroid with her namesake.
  • Nyx is a shadowy figure in Greek mythology but from the extracts about her, it is gleaned that she was a figure of great beauty and power.
    • Her son Moros (Doom) is mysterious as well and is believed to be omniscient, omnipresent, and omnipotent, as he drives all things to their ends.
  • In some myths, Styx, the goddess of the boundary between life and death, is Nyx's daughter.
  • Her Egyptian equivalent is Kauket.
  • Her Norse equivalent is Nótt.
