Poorer citizens of Kaer Maga, the City of Strangers, have been going missing, and while many think they've simply left to emigrate to New Thassilon, a purported haven for outcasts, an independent journalist feels that there's something unsavory going on. Kaer Maga doesn't have much in the way of authorities, and those who hold any power aren't taking her seriously, so she's turned to the Pathfinder Society. The PCs need to figure out what's going on, and if it is unsavory, perhaps put a stop to it.
