The decks in this addon allow you to create random cave/mine systems or custom tailored ones. There are a lot of fun features, including drag and drop tokens to dress up your maps, such as a campfire that already emit light (Dynamic Lighting required)! The bundle also comes with 4 preassembled maps with dynamic lighting to start you off with. Check them out here (there is a video that details how they work): <a href="https://marketplace.roll20.net/browse/bundle/3837/geomorphic-cave-and-mine-tile-bundle" rel="nofollow">https://marketplace.roll20.net/browse/bundle/3837/geomorphic-cave-and-mine-tile-bundle</a>
