Nyrilyx, or Nyx, is a swamp monster that lived alone all her life. She is shy, quiet, lonely but she becomes teasing, cunning and cold. She has a human body with blue skin, and tentacles. Her skin is covered by a venom that slowly puts anything it touches to sleep. She feeds on dreams. Her strategy is to cling on her prey and never let go until the prey fall asleep. As long as she remains in contact with prey, prey won't wake up. She can invade the dream of prey.
