The wolf’s den is meditating area for the squad twelve. Usually, only captain of the fifth division ever goes in here. It is said to be complete darkness and complete silence. This is where he is able to get into his human nature here. A little pathway that leads to a gigantic cave that is pitch black on the inside. The area is big enough inside to train if one needed too with multiple pillars to scale and jump from during the actual meditation training. There is air coming from the top but even by captain standards, no one has ever made it to the top.
