Nausicaä is the princess of the Valley of the Wind, a state on the periphery of what was once known as Eftal, a kingdom destroyed by the Sea of Corruption, a poisonous forest, 300 years ago. An inquisitive young woman, she explores the territories surrounding the Valley on a jet-powered glider, and studies the Sea of Corruption.
The valley of the wind lead by the aging and sick king Jhil, is subordinate to the Vai emporer of Tourumekia. Most cities, tribes, villages, valleys ect. of the new earth are in some form of another part of either Dorok or Torumekian command: Two massive nations that have been at odds or at war for thousand(s) of years. Torumekia has a large army, and does not appear to be religious. The Doroks are secular, with military and strategic higher ranks assigned to priests. Doroks and Torumekian people usually dislike each other, but there are various exceptions.
The Vai emporer has four children: 3 unnamed sons, and his daughter Kushana. The royal family is notorious for internal conflicts, backstabbing schemes, and desperate attempts to obtain or hold on to the power of the throne. The Doroks have a stabler government composed of the emperor, his brother, and the “Council of elders”.
