From publisher blurb:
Burzyn is the largest settlement in the Kingdom of Chybisa and the principal seat of King Verlid VII of Clan Geledoth. The castle controls the only bridge over the Ulmerien River and is perhaps the most impressive fortress on Hârn.
Burzyn prospers through trade. At roughly half way between Thay and Tashal on the Genin Trail, it is a natural stop for travelers and caravans. It is also a center of river trade. Much of this is between settlements within the kingdom, but the town sees the occasional vessel that has braved the Gulf of Ederwyn to bring goods from Evael, Melderyn, or points beyond.
The Burzyn article describes the settlement's history, government, religion, economics, and military forces. It includes color GM and player maps of the settlement and brief descriptions for many local craftsmen and other locations in the town. Floor plans and detailed descriptions are provided for the castle and seven other locations: house of courtesans, Laranian temple, shipwright, embalmer, mercantylers' hall, Peonian enclave, and ruined tower.
