Waterdeep has seen a sudden influx of beraggled and battered travelers - refugees, some are calling them! - from the east central region of Faerun. Some seem to working towards setting up a permanent residence, while others seem to be packing up for an elongated stay ... and one group was seeing being admitted into the palace. An audience, perhaps?
A few louder voices, one or two of whom have been seen wearing symbols of the Zhentarim, lament about Zhentil Keep, and the all-too-sudden appearance of a colossal army of mindless - although extremely effective - soldiers. The implication is fairly certain: at least some of these folks are from the Moonsea. What catastrophic event is happening?
