From publisher blurb:
Its waters are the deep purple of the most precious amethyst; its shores hold some of the most dangerous locations in Faerun. It is the Moonsea, home to Zhentil Keep, the Citadel of the Raven, and thousands of ordinary folk who merely want to make and honest living.
Hark to the words of Melandryll Belarod, the bard whose writings form the bulk of this material. He has experienced firsthand the horrors of ruined Hulburg, he desolation of Sulasspryn, and the stench of Mulmaster. His travels aboard the Devawing have produced this chronicle of the towns and people of the Moonsea, including both havens and dangers. Belarod knows of the Citadel of the Raven, a ten-mile-long series of fortresses and barracks, site of a terrifying betrayal. He also has evaded the Zhentilar, the crack forces garrisoned at Zhentil Keep.
