Who was Gulveig? This enigmatic goddess was the Vanir’s secret weapon in the war with the Aesir gods. Her ability to intensify greed and despair allowed her to single-handedly bring the war to a crippling end. Hey magic drove the Aesir to bicker and fight with one another- to the cusp of civil war.
