Bunkidou Grounds

The Bunkidou Grounds (分岐洞穴, Bunkidouketsu Grounds, Literally meaning: Branching Burrows Grounds), also known as the "Land of Spiders", is a mostly unexplored location made from slightly cramped and twisted burrows and tunnel networks underground. It being the land of spiders, it is also the location where all of the Sage Spider summons live. It is home to giant and lesser spiders alike, all ranging in different colours and featuring unique patterns for each spider. The Bunkidou Grounds are a dark and dreary place, ruled over by the Unseen Queen (見えない女王, Mienai-joō). There are Lesser Spiders that assist in the training of Senjutsu, but none seemingly have any authority other than the Unseen Queen.
