This one page-ish adventure is really cuts to the meat of Old School RPG. While it is a module for novice adventurers, it is clearly not an introductory module that holds the game master's hand. That's a Good Thing. This little dungeon can be inserted into almost any other place you need a side quest. And the price? You can't bet it.
Dan Proctor is known for his rulebooks, but he's got module designer chops to boot.
