Shiroato (白跡, Literally Meaning: White Ruins or Castle Ruins) is the name of a location and an organization located in the Land of Lightning. It rests on the bottom of a mountain and was once used as a training area for Kumogakure's Head Ninja until it was soon rediscovered by the organization's founder, Hisoka. As a defense, seals containing Lightning can be activated by Hisoka to electrocute any foes around the building.
