  Introduction 
  If The Goonies taught us anything it’s that where there are caves there is adventure.  
  While there might not be pirate ships lurking underneath every seaside town, real world 
  caves have also provided both amateur and professional speleologists with a great many 
  adventures of their own. There have even been real life instances of finding great treasures 
  lurking in caves such as a 2015 discovery in Israel that involved a stash of coins and 
  trinkets from nearly 2,000 years ago! Perhaps this is part of what sparks the imagination 
  about caves. In the unknown there is endless possibility.  
  In this volume you will find a total of 16 tables to help you create a cave system of your 
  own, ready for any brave adventurers who are willing to take it on. As with many of our 
  other publications you will find no hard stats or numbers so that anything you create can 
  be easily transported into the setting of your choice. 
  Happy Gaming,  
  Rowan 
  Instructions 
  The only items needed are a pair of percentile dice or a d100 and something to write down 
  your results with. 
  To find the results simply roll the dice, match them up with the percent represented in the 
  first column of each table and match it up with the next column over. 
  Note: For the purposes of these tables chamber refers to any room like area of a cave and 
  may be used interchangeably with cavern. Passage refers to any long hall like area 
  connecting chambers.

  beautiful swirling patterns. 
  27-33%

  shaft that passes through the middle of this chamber.

  water pocket deep below. 
  7-12% 
  An extraordinarily large white snail leading a group of much smaller snails 
  passes in front of the party without paying them any mind. 
  13-19%

  give away beneath an adventurers feet.

  62-68% 
  Two faint lights, tiny as dots, appear in a dark corner of the cave. They

  the lures of some huge creature, but it ignores the party if they draw near. 
  69-75% 
  The party comes across a group of rats seated in a circle around a single rat 
  that is chattering excitedly. Upon noticing the party the rats scatter, but not 
  before throwing the party some very dirty looks.

  The passage that the adventurers are traveling down becomes incredibly 
  narrow, forcing them to crawl along. 
  82-87% 
  A section of nearby wall begins to crumble like sand. 
  88-94% 
  As a faint wind blows through the cave, a low moaning can be heard behind 
  a stone against a wall. Removing the stone reveals a hidden chamber, 
  completely bare and perfectly carved...but no-one within. 
  95-100% 
  As the party travels beside a great stone structure, it becomes apparent that 
  the structure is the fossilized remains of a great dragon. Directly beneath, 
  they find three fossilized eggs, and one that begins to rock, faintly, at their 
  approach...
