Located somewhere within the Land of Lightning's many mountain ranges is a valley called the Valley of Clouds and Lightning. What was once a beautiful water-filled valley covered in wispy clouds or mystic fog is now home to the darker creatures. The Raikage has forbidden any Genin to venture here without a Jonin or -- preferably -- a member of the Cloud Village's ANBU. Sinister rogue ninja are rumored to lurk within the shattered rock and even hide in the black water to surprise any unsuspecting Shinobi of the Clouds.
