The bottom level is the Retreat-proper and features several rooms where druidic relics could be stores, a central cave with a hot-spring, and the disused quarters for the druids when they are in human form. At the rear is another large chamber where the druids hibernate in their bear-from next to warm volcanic rocks and gently glowing crystal formations.
“The central cave has a large domed ceiling that glows with an almost dawn-like yellow light from a local phosphorescent fungus. The air is warm and damp as the deep pool in the center of the cave bubbles and steams. Flowing into the center is an almost musical waterfall that splashes off the rocks and flows underneath a simple wooden bridge.”
