Mine Tunnel

Tight (dusty, close air), wood supports (rotting,
infested with termites), fungus (glows in the dark,
poisonous), continues into darkness.
Carved by former captives. There are several forks, a
few have collapsed (buried skeletons, random loot).
▶ Following these tunnels: leads to a cave that exits
deep in the jungle. GM Tip: It can also lead to additional
dungeons, encounters, and treasure.
