The role of the Norns in Norse mythology is to determine the fates of both gods and mortals. These three sisters, named Urd (the past), Verdandi (the present), and Skuld (the future), weave the threads of destiny at the base of the cosmic tree Yggdrasil. Their actions underscore the belief in predestination and the interconnectedness of all beings within the universe. The Norns serve as a reminder that fate is an intrinsic part of existence.
