Yggdrasil (Old Norse: "Yggdrasill") is the name of the immense cosmic tree that serves as the connection between the Nine Worlds in Norse mythology. Known as the World Tree, Yggdrasil was said to lie at the very center of the universe, supported by three roots which extend far away into varying locations. Various creatures dwell within Yggdrasil. Upon the onset of Ragnarök, Yggdrasil will shutter and groan, ultimately crumbling as the universe meets its end.
