Valley of the End (Earth-2165)

The Valley of the End is a forested area near the border between the Land of Fire and the Land of Sound. It was the site of the legendary battle between Hashirama Senju and the Uchiha Clan's founder, Madara Uchiha, as well as home to two colossal statues in a waterfall to mark their confrontation and the founding of the Konohagakure.

History
Once merely a massive forest, the Valley of the End was created after the barrage of Hashirama Senju's Top Transformed Buddha Technique in his duel against Madara Uchiha, after the latter fought Senju duo to him becoming Hokage. Hashirama was victorious, and Madara was killed.

What was left of the destructive scars of the battle became known the Valley of the End, and its waterfall, set between two massive statues erected in the images of Madara and Hashirama, served as a border between the Land of Fire and the future nation of the Land of Sound; the statue of Hashirama remained at the side of the Kingdom while Madara's statue stood at the other side, symbolizing his betrayal and abandonment of the Konohagakure. The statues were contructed in the traditional bending sparring position, the protocol before any duel.

Years later, in 226 AG, Naruto Uzumaki chased his former teammate and rōnin Sasuke Uchiha to the Valley of the End to return him to the Hidden Leaf, but Sasuke attempted to kill his former friend to gain the Mangekyō Sharingan for himself. In the end, both used their fullest power, but Sasuke was victorious. The statues of Madara and Hashirama were mildly damaged in the struggle.
