One of the larger caves in the system of Underground tunnels and caverns is used for the meeting place of the entire Clan. It is large enough that it can hold the entire clan and more. There is a small lake near the center that has formed from hundreds of years water dripping from the ceiling. Unlike many of the other caverns, this one is natural, not manmade

The Shôgun's Chambers are a rather large, man-made, stone cavern that can easily fit a Shôgun and maybe a few other cats as well. The chambers have plently of moss growing on the walls so that the Shôgun rarely has to leave to find bedding. Otherwise, there is nothing special about this cavern.

The Warrior's Den is a large, man-made cavern that can house many cats all at once. This Den is the home to any rank of warrior, inlcuding Trainees. There are always many moss beds on the rock floor, but most of the materials come from other caverns or from the outside world.

The Nursery isn't very large and it is one of the driest caves within the Underground, along with the Elder's Den which is adjecent. There is plenty of room for the Mothers with kits that come here during the year. The Medic's Den is also adjacent to this den. Within the Medic's Den their are herbs, a fresh supply of water, and places for the Medics and Trainee Medics to sleep.

In a cave adjecent to the Nursery there is a dry cavern that is meant for the elders of the Clan. The floor is earthern and more comfortable than a stone floor is and it is kept very dry, to keep the elders from being damp during their time in here. The Medics are just across the Nursery, just in case.
