The Underwater Caverns Discovered not long after the forming of the Rebellion, the Underwater Caverns are considered to be a perfect fallback area in the event that all should go wrong. It is thought that no demon knows of the location of the caverns and humans are not told of their existence until after they have proven themselves worthy. A short swim through a watery tunnel is all that is needed to reach the large cave and, within its reaches, there are many smaller nooks and crannies that can be used as homes. Some scattered holes to the surface (none large enough to climb through) provide enough ventilation to make a few fires perfectly safe and there appears to be small plots of water made drinkable by filtration through the bedrock.
