In Norse mythology, Njörðr (sometimes anglicized as Njord, Njoerd, or Njorth) is a god among the Vanir. Njörðr is father of the deities Freyr and Freyja by his unnamed Van sister, was in an ill-fated marriage with the goddess Skaði, lives in Nóatún and is associated with sea, seafaring, wind, fishing, wealth, and crop fertility.
Njord is a Persona of the World Arcana. In order to summon him, the player needs the Material Card Noatun, which can be acquired by returning the Persona Gullinbursti in the Velvet Room at MAX Rank. However, Demeter can also mutate into Njord.
