The dens off all the pack members are located here. The many different caves all have many jewels decorating their walls. The largest cave at the back of the mountain is composed completely of sapphires. This is the Alpha's den and no one is allowed inside, unless invited. In the middle of the caverns is a hot spring, where the members of Tierras el Cantar can gather and wash in the winter. This hot spring warms all the caves.
