From publisher blurb: The Missing Pin is a 2nd-level adventure designed for 4 to 6 characters. In the Lost Lands setting it takes place in the Unclaimed Lands north of the Borderland Provinces at the point where the Great Amrin River meets the Glimmrill Run. There stands the small town of Gumspur. If you are not using the Lost Lands setting, the Gumspur can be place in a semi-remote area along any major river that sees significant barge traffic.
