Question: what is it called when you believe in norse gods?
Answer: You can either call it Heathenry or Ásatrú. Heathenry is a bit more general though, and can also encompass beliefs and practices associated with other Germanic pagan Gods, like Anglo-Saxon or Germanic ones. Åsatrù, on the other hands, only really refers to the religion surrounding the Pagan Gods of ancient Scandinavia.
