Unknown to most, the interior of Hokage Rock has been hollowed out with a system of caves made to be self-sufficient if need be. In these caves are all of the modern amenities, Barracks, offices, a cafeteria. Built like a military base, this is the new ANBU HQ after the old one's entrance was revealed. To enter this new complex, one must leave Konoha and locate the hidden tunnel entrance in Fire Country itself, which has windcart tracks going directly into and out of the HQ powered by a natural gust in the tunnels themselves. It has been fashioned to look like the inside of a normal building, with some areas actually full windows to the outside to allow natural light in. These areas are well hidden on the outside by chakra barriers and illusion.
