After being cautious and much debate, the chest finally opens and you see a bright light...and stairs going down??!  An adventure for level.....well, I guess it depens on which path is chosen as this doesn't follow a balanced encounter approach!
 
This adventure follows the For Gold & Glory ruleset which is similar to second edition of the world's most popular roleplaying game. The adventure can be placed anywhere, as it is a magic chest that opens to reveal descending stairs and a dungeon beyond...
