Into the Dark Den is a straightforward, fun adventure if you're looking to start playing Pathfinder or just need a quick pick-up adventure to play. It relies on the classic premise of "adventurers take shelter in a location, only to find out it goes deeper and something is wrong!"

The "something wrong" in Into the Dark Den leads to an interesting variety of NPCs and challenges, and despite the adventure's brevity and simplicity, the backgrounds of both the story and the characters involved are given care and attention. Is it likely to come up in session? It depends on the group, but having it there makes reading and prepping the adventure more interesting for a GM, and an extra bonus if the players engage with it.

I sort of "co-GMed" this adventure with a friend who wanted to try her hand at being a Pathfinder GM, and it was a great time!
