Northern Paganism is the blanket term that refers to traditional Norse polytheism. Followers of Northern Paganism often call themselves Heathens.
Under the blanket of Heathenry, Northern Pagans may follow Asatru, Vanatru, or Rokkatru.
Asatru, meaning “true to the Aesir,” indicates Aesir-focused worship based on primarily Icelandic mythology. The Aesir are the gods of the main Heathen pantheon, including Odin, Thor, and Frigga.
Vanatru and Rokkatru are parallel terms that were invented to refer to different devotional sects; Vanatru means “true to the Vanir,” and those who follow Vanatru worship Freya, Freyr, Njord, and sometimes Nerthus.
Rokkatru, or “true to the Rokkr,” is the most controversial sect of Northern Paganism, as its followers worship the jotun, a primordial class of gods who represent chaos. There is no evidence that ancient Northern Pagans worshiped jotun. Many Heathens view Rokkatru as antithetical to human wellbeing, as life-sustaining order was a service by the Aesir; therefore, jotun domination would mean human destruction. Rokkr gods include Loki, Angrboda, Hela, Fenrir, Jormungand.
