**Nyx**, also called **Nox**, is the Primordial Goddess of the Night from Greco-Roman Mythology. She is the mistress of the Mansion of Night, the wife of Erebus, and the stewardess of the House of Hades. She is the mother of many chthonic gods, such as Thanatos, Hypnos, Nemesis, Eris, Charon...

## Overview: **Nyx**

**Nyx** (Ancient Greek: Νύξ, "Night") is the Greek goddess (or personification) of the night. A shadowy figure, Nyx stood at or near the beginning of creation and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness).

Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power and beauty that she is feared by Zeus himself.

## History

Nyx is one of the Protogenoi, the Greco-Roman Primordial Gods created by the Progenitor God Khaos. Like the rest of her siblings and many of the Second Order Primordials, she was born in the Galaxy Cauldron roughly 14-billions years ago, alongside the birth of the Milky Way galaxy.

After the firmament was settled and the primordial chaos was reshaped back into the Mortal World and the Divine World, Nyx and Erebus came to live with Tartarus within the Depths of Tartarus, the first underworld, where she created the Mansion of Night. For most of the time, she lived in the Mansion of Night where she rules, and only leaves the Depths of Tartarus to bring forth the night when the day ends.

She and Erebus then got married and, roughly 4.6-billions years ago, Nyx became pregnant with her first children, Aether and Hemera. And throughout the courses of prehistory, she gave birth to many other chthonic gods, such as Thanatos, Hypnos, Nemesis, Eris, Charon... After Hades came and took over as the [God of the Dead], Nyx and her children swore loyalty to Hades and she became the stewardess of the House of Hades.

## Appearance

Nyx has many forms, the most common of which is that of a young woman with ivory-white skin and exceptional beauty. She has long black hair reaching down to her waist, amethyst-purple eyes, and pointed elf-like ears. Radiating from her body is a mysterious and tremendous dark aura.

### Clothes & Attires

Nyx is typically shown wearing a gothic lolita-style frilly dress attached to a corset jumper skirt and a white blouse. When meeting Team DxD, she was shown wearing a black evening gown reminiscent of Audrey Hepburn's famous Givenchy dress, black elbow-length gloves, with a necklace made of skulls and obsidian shards, and a black off-shoulder cape.

In Ancient Greece, she used to wear a black-and-purple peplos fastened at her shoulders with brooches in the shape of gold moons and skulls, a dark-purple robe with gold linings fall down her feet, and her hair was styled hair and was decorated with a wing-shaped hair ornament.

### Alternative Forms

Nyx's true form is that of a vaguely feminine humanoid being form of dark energy, with bright eyes that shine like quasars upon a featureless face. Giant waves of primordial darkness roll out of her figure and create the illusion of a dress made from a fragment of the universe itself. Crowned upon her head is an aureola of dark mist and glistering stars.

## Personality

Like many Primordials, Nyx is an ancient and powerful goddess who holds an impartial stance in regard to the on-going events within her own pantheon. For the most part, she'd rather spend her time in the Mansion of Night resting in a formless state, or performing her duties as stewardess of the House of Hades.

For the most part, she sees the younger gods as "screaming, irritating toddlers" and has little respect for them, though she does recognize true power when she sees it. Within the Greco-Roman Pantheon, Nyx has ever appeared to respect her fellow Primordials and the Elder Olympians, who have won her respect through their might and their authority.

Like most Primordials, Nyx has no feelings whatsoever when it comes to mortals, deeming their troubles and woes as meaningless to her. According to her, as the Night serves little importance to humans' continuous survival, she isn't required to care about mankind as much as other gods.

She can be very caring and protective, though her overprotective nature tends to make her children embarrassed most of the time. The thought of a child of her being harmed can launch her into a blind rage, completely disregarding any consequences that might come after. Despite this, Nyx still acts very strict toward her children, expecting the best behavior from them.

Like many gods, Nyx is concerned about the unchecked power of the Sacred Gears, especially the Longinus which can easily disrupt the natural order. In addition, she also admits that her distrust in Longinus wielders largely originated from the Longinus' nature, which are God-Slaying weapons with the potential to kill even primordial gods like her.

Unlike Erebus and Tartarus, she neither likes or dislikes the Three Factions, though she does admit to have laughed when she saw arrogant gods falling into despair when their followers converted to Christianity. However, in order to keep other gods in line and to prevent a divine retribution from Heaven, Nyx infiltrated the Alliance of Hell as Hades' double agent, secretly passing the Twelve Olympians information she gained from other members of the Alliance.

## Equipment

**Night Chariot** (夜の戦車, *Yoru no Sensha*): The divine chariot of Nyx. It is an Roman *biga* chariot made out of sharp obsidian and Stygian Iron, pulled by two thestrals named "Apóchrosi" (Shade) and "Skiá" (Shadow). Every night, as the sun begins to set, she will place her mantle of night over her shoulders and ride her chariot out of the Realm of the Dead, bringing the night to the Mortal World.

## Trivia

* Nyx feels uncomfortable when someone asks her who her favorite child is.
* Like other Protogenoi, Nyx has no Roman form as her Roman influences aren't strong enough to manifest in an additional form. According to her, she had slept throughout the majority of the Roman Empire, though she did wake up several times to use the bathroom.
	+ While she doesn't mind being called Nox by the Romans, she herself has a hard time reminding herself that Nox is her Roman name.
* The 3908 Nyx asteroid is named after her.
	+ Nix, one of Pluto's moons, was renamed by scientists in 2006 in her honor, though with an "i" instead of a "y" to differentiate between it and the asteroid.
* Nyx Mons, one of the mons on the planet Venus is named after her.
* Nyx is a shadowy figure in Greek mythology but from the extracts about her, it seems that she was a figure of great beauty and power.
* In some myths, Styx, the goddess of the boundary between life and death, is Nyx's daughter.
