Backyard Dungeon

When I got the call that my estranged grandfather had passed away and left me his trailer and a plot of land, I was just excited to own a little property and save some money by not having to pay rent. Then I found a strange cave in my backyard. It wasn’t a sinkhole, or a bunker, or a mineshaft… It was a dungeon. Full of crazy caverns, unbelievable monsters, and sexy, fantastical women in distress. Oh, and loot. Lots and lots of loot that was just ripe for the taking. So, what am I going to do with it all? And how do I keep everyone else from finding out about it?
