Eternal Nations is an empire-building simulator set in a fantasy world. Its top-ranked player, the legendary Takuto Ira, loses consciousness while playing it in the hospital. When he awakens, he finds himself in a world strikingly similar to the game on the continent of Idoragya. There, he encounters Sludge Atou, his favorite unit from Eternal Nations. When Atou tells him she remembers everything, Takuto makes a decision: to build an empire for the two of them alone. Together, they establish the evil nation of Mynoghra. With a kingdom of unique and quirky Dark Elves and the support of the mighty Hero unit Atou, Takuto begins ruling his new empire, using game-like systems that are nothing short of cheats in this world.
