Note: The Drawing was made By me and it was an illustration already for the story of the birth of Loki here in my blog, but it serves well for this post as well!
First, there was Asatru, which meant, technically, “True to the Aesir”, or the Norse/Germanic Gods of sky and war and culture. They included Odin, Frigga, Heimdall, Baldur, Iduna, Bragi, and many others. Eventually, those whose religious practice concentrated on the Vanir – the second, more agricultural pantheon of Gods including Frey, Freya, Njord, and Nerthus – decided that they would be called Vanatru. Some time after that, Abby Helasdottir of New Zealand coined the term Rökkatru, for those whose primary focus was the third pantheon of underworld Gods. These include Hela, Loki, Angrboda, Sigyn, Fenris, Jormundgand, Narvi and Vali, Surt, Mordgud, and Mengloth, among others.
