Overview
"The goddess of the night in Greek mythology. She was born out of Chaos and gave birth to many offspring, including light (Aether), day (Hemera), death (Thanatos) and the Moirae Sisters among others."

- The Infernal Compendium

Nyx, also known as Mother Night, is the primordial goddess of the night from Greek mythology. Originally said that she was born from chaos and her name means "the mother night."

She is depicted as a goddess draped in long flowing black robes. Versions of her birth and origins vary, but one interpretation has her as a creator goddess, laying a silver egg that produces the gods responsible for the creation of the world.

She gave birth to many offspring, including Light (Aether), Day (Hemera), Death (Thanatos), Sleep (Hypnos), Doom (Moros), Retribution (Nemesis) and the Moirae Sisters.

In Roman mythology, she is known as Nox.

Appearance
Nyx first appeared as a beautiful young woman with dark-purple eyes, long black hair, and pointy ears. Her body also gave out a tremendous dark aura.

She wore a cute frilly dress attached to a corset jumper skirt.

Her true form, however, is that of a vaguely feminine humanoid being formed of ash and smoke, with bright eyes that shine like quasars. Giant waves of ancient darkness roll out of her figure every time she moves. She wears a long dress that's void black, mixed with the colors of a space nebula as if galaxies are being born in her bodice.

Personality
Nyx is a cheerful, yet sadistic goddess who enjoys seeing others in pain and suffering. However, she does have an honorable side to her as she greatly admires "true heroes" and those who gain their power and authority through noble means.

She can be caring and protective, according to her daughter Nemesis, as she is known for taking in those who were abandoned into her wings and raised them as her own children. She is protective of her children and grandchildren, and is known to rain her maternal fury onto those who harm them.

Like many other gods, she is shown to be concerned about the unchecked power of the Longinus Sacred Gears, as she views them as abnormal anomalies that greatly interfere with the world's natural order.

Early Life
Nyx was created by Khaos with the creative energy generated by Eros and Eurynome, her eldest siblings and the first of the Greco-Roman Primordials. She lives in Tartarus in the Mansion of Night, where she stays during the day and leaves during the night to bring the day-night cycle to the world.

She married her brother Erebus, in addition to taking her younger brother Tartarus as her lover, and the two had their first children: Aether and Hemera. However, due to the complication of Hemera's birth, she became unable to bear any more children naturally, thus making her turn to creating new children for her to call her own.

At some point in the ancient past, she was gifted with the knowledge of creating the Reapers from the Archreapers, and was tasked with the duty of creating new generations of Reapers to harvest the souls of deceased mortals and take them back to the Realm of the Dead, with hers responsible for taking them to the Greco-Roman Underworld in particular.

She later taught it to Persephone after she married Hades and became Queen of the Underworld.

Heracles' Siege of Troy
Under Hera's order, Hypnos, son of Nyx and God of Sleep, put Zeus under an enchanted sleep so the Olympian goddess could shower Heracles, who was returning from he had besieged the Trojan king Laomedon, with misfortunes without Zeus interfering.

When Zeus found out about Hypnos' involvement, he became furious and chased him throughout the Grecian cosmos. He would have struck him out of sight in the sea from the bright sky had he wasn't able to reach his mother in time. Due to his respect for the Primordial Gods, he allowed him to slip away this time, though warning him he would be justly punished if he used his powers on the gods without his order again.

Harming, Trapping, & Banishing

 * Witchcraft: As witchcraft is a form of magic wielded by witches to oppose those of heavenly nature, pagan gods such as Nyx are susceptible by witchery. There are many witchery spells and rituals that can be used to trap, weaken, and hurt her, with some rituals rumored to be capable of even killing immortals such as the pagan gods.
 * Celestial Weapons: Weapons made out of sacred metals, such as Celestial Bronze or Imperial Gold, can be used against the majority of supernatural beings, including pagan gods such as Nyx.

Killing

 * Divine Weapons: The divine weapons of the gods, which are crafted from sacred metals and are imbued with their wielders' divinity, can be used to kill or injure fellow immortal gods like Nyx. However, due to her being a Primordial Goddess, only a chieftain god’s Symbol of Power is capable of killing her.
 * Enochian Weapons: Nyx can be killed using weapons made out of Enochian metals.
 * Longinus: As the Longinus are Sacred Gears made out of Enochian metals of the highest-ranking, forged by Heavens' forges with the highest-quality Enochian technology and are imbued with fragments of the Biblical God's divinity, those with enough skills and experience can absolutely and permanently killed Nyx, to the point where she can never be reborn or resurrected again.
 * Faustian Weapons: Nyx can be killed using weapons made out of Faustian metals.
 * Primordials' Weapons: Weapons created and wielded by primordial entities can be used to permanently and absolutely obliterate every and any being in existence but other primordial entities, erasing their entire existence from the worlds so that they can never be reborn, or resurrected again without being saved by God's omnipotence.
