The film opens with the massacre of a primitive tribe by Silla’s first king, Bak Hyeokgeose of Silla and his technologically advanced army. The Auta tribal chief in death throes vows vengeance against Silla, and their blood and resentment fill the place where the Sacred Tree was standing, and turns into a lake. To seal off the Auta tribe's force of sorcery, he drives his Holy Sword deep into the Sacred Tree.
