Tremble Rock Cave is known to be built into a humongous cave and has been there for numerous decades. Doton users have kept the entire city stable and kept the buildings from toppling over from the numerous trembles in the rock that come from the Tremble Mine. The mines have numerous accidents and cave ins but normally doesn't amount to any casualties as many Doton users are watching over those who work there. This city is home to well known forgers who forge weapons, armor, and equipment. Those who want specialized armor must report to this city. The Hyuuga and the Multiple Mouth clan both dominate this area together. The Kamizuru are currently being discriminated against by the Multiple Mouth clan and haven't reached out to the Hyuuga for assistance at all. They also reside here but are at the lower ends of the cave to signify their status in the community.
