So good! I spent 30 minutes reading Caverns and now I can't help but scoop up all the rest. The descriptions are modular, generic (in the good way), rich, and grounded in an appreciation for the inherent drama of the environment.

This is perfect for GM's like me who love to run low-fantasy homebrew settings, because when I need a little helping hand, it's hard to find something that doesn't bring in all the setting baggage of a fully-packaged module.
