The apprentice's den is a large hollow log from an unknown tree, placed near the Highmound and probably the farthest den away from the shore, other than the leader's burrow. A few tiny patches of fresh moss grows in and outside of the log, and fungi tends to pop up in between the cracks, which the apprentices pick off immediately. Inside is warm and sunny because of the cracks that allow light to seep in. Moss and grass is lined along the bottom to provide a comfortable ground. Occasionally a bored apprentice might decorate the den with colorful stones, shells, or feathers to make it prettier.
