Nioth-Korghai

Nioth-Korghai were said to be space vampires who drained victims of their lifeforce when woken from their crystal tombs. The scavenger Rey heard tales of encounters with these beings from Corellian spacers passing through Niima Outpost on Jakku.

Description
According to Corellian spacers encountered by Rey, the Nioth-Korghai were space vampires considered so seductive and regal that none could resist their appeal. They slept in crystal tombs along the commercial hyperspace routes, and when awoken would drain victims of their lifeforce, absorbing the warmth and color of those who willingly surrendered. In this way the Nioth-Korghai could feel alive, if only for a brief time.

History
Prior to her departure from Jakku as the First Order–Resistance war began, the scavenger Rey heard of the Nioth-Korghai from Corellian spacers passing through Niima Outpost after drinking at Old Meru's. They talked about encountering Nioth-Korghai in their crystal tombs who, when awoken, would drain victims of their lifeforce. Later, while receiving a Force vision of the late Duchess Satine Kryze from the spirit of Obi-Wan Kenobi aboard the Millennium Falcon en route to Ahch-To, Rey likened the pale-skinned Mandalorian to the space vampires, and imagined her feasting on willing victims to feel alive again. Rey considered that her creativity could lead her to produce holofilms after the defeat of the First Order.

Behind the scenes
The Nioth-Korghai were first mentioned in Das Flute's 2016 canon erotic fiction "The Ways of the Force". The name originates in author Colin Wilson's 1976 novel The Space Vampires, which has been generally accepted as part of H. P. Lovecraft's Cthulhu Mythos.
