Record of Ragnarok: Parallel Universe

When Zeus brought down the wooden hammer that would decide humanity's survival, Xuandu the Great Mage, a senior disciple of the Mystic Sect, arrived with the Six Sages of the Primordial World to stop him. As the two sides remained locked in a standoff, the half-human, half-divine Valkyrie Brunhilde proposed using the ancient rules of Ragnarok, a war between the gods, to decide humanity's fate. (The Eastern pantheon follows the worldview of the Primordial World, but the characters have all been weakened to the level of the gods in Record of Ragnarok. Historical figures will also be altered to some extent, and the unofficial histories and original content will inevitably differ from actual history, much like in Record of Ragnarok.)
