This is an awesome short adventure that is perfect for a one shot, launching a new campaign, or introducing new players to the hobby. It's straightforward and easy to run while leaving tons of room for you to introduce elements from other suppliments or your own plot hooks. Everything you need is in the PDF, including stat blocks, maps, and tons of handy tips for the GM.
The way the NPCs and encounters are presented allow for GMs to introduce them to players in ways that encourage creative play. If you want to stetch this adventure out into 2-3 sessions and allow for character development and an interesting narrative, there is a ton of room for that. Or if you want to run through the whole thing in an evening as a one shot it's good for that too! With a little tweaking you could easily drop the scenario into an existing campaign and save yourself some prep between sessions.
This is a great, versatile adventure that any GM should have in their back pocket for those moments where they need an adventure in a flash, or the campaign is losing focus, or to run for a group of first time players that want to get their feet wet.
