This cozy underground location is where Fox dwells. It is his peace and serenity. He enjoys nothing more than reading a good book, cooking a warm meal, or simply just sitting by a warm fireplace. While simple in appearance, it has numerous hidden areas, compartments, rooms, escape routes, and technological advancements built in. 

It is also located within a connected tunnel system that travel for miles throughout the plains. Its use cases are various. From living quarters, general transit, strategic battle routes, supply chain travel, storm shelter, irrigation pipelines, storage, secret stashes and more. And unlike other members of his canine family, Fox is not a nuisance to farm lands, he is a tremendous ally. And uses the Den tunnels to help both service and watch over them.
