This challenge is that the world of Naruto is a continent west of Westros. I think seeing samurai and ninjas in Westros be an interesting story. All the nations in the manga are still there and ruled over by an emperor. Their society and technology are like feudal japan except men and women are equal in every way. The continent is discovered by a lost trader ship from Westros that lost in a storm or vice versa.
Guidelines:
-The Shinobi Wars in Naruto are civil wars that happen in the empire and the wars lasted months and years not couple days like in the fourth war Naruto canon.
-Chakra can still be used but not like in the manga and anime. They would be godlike in Westros and that would be extremely boring.
-All or some Naruto characters can be in the fic if you want.
-Story must take place in the Westros and Essos and some on the Naruto continent.
-The story I think would be interesting if it took the place of Shippuden series or after it so the forth war still happens.
