A Pathfinder Society Scenario designed for 7th- through 10th-level characters. 

A mysterious abandoned laboratory is discovered in the Arcadian Ocean, with clear signs of occult experimentation having occurred at some point. The Waterfall, strangely fascinated by this new find, sends a group of Pathfinders to investigate and gather whatever research they can find inside, while also ensuring the building poses no further threats. Deep inside, a soul and forgotten memories wait, hungry to be found and revealed to the light. The research and artifacts inside seem like they'll lead to answers about the enigmatic Waterfall, though this information may turn out to be unwanted.

This adventure is the third part of the four-part Equal Exchanges metaplot arc in the Year of Unfettered Exploration. This arc began in PFS2 #5-04: Equal Exchanges – Necessary Introductions and PFS2 #5-09: Equal Exchanges – Skymetal Hoard, and will be continued in PFS2 5-18 (for levels 9-12).
