A mysterious woman arrives and saves a group trapped by powerful magic ice, revealing she is from Valhalla, an unknown place outside the Magic Association. The locals are stunned by her forbidden and intense magic, learning she is an independent four-star archmaster rather than an official mage. Despite gratitude, she refuses any reward, claiming she was summoned by Valhalla itself and warns them to clean up the aftermath. Meanwhile, suspicion arises about archmages existing outside the Association, and questions grow about a missing figure named Noah, setting up new uncertainties about allegiance and power.
