Valley of Clouds and Lightning (Earth-1529)

The Valley of Clouds and Lightning is a massive valley located near Kumogakure, in the mountaineous regions of the Land of Lightning. Covered by clouds and fog, the valley was home to a cavern where Killer Bee, the Jinchuriki of the Eight-Trails, trained.

History
After the Yotsuki Clan swore loyalty to the First Raikage during the First Great Shinobi World War, he gave the piece of the land for the clan to use as their own. In 26 AG, the valley was devastated by Killer Bee during his fight against Tobi duo to the Eight-Tails' Tailed Beast Ball attacks.
