Nebula Obscura: Worlds of Ravenloft

A Ravenloft Netbook

From the introduction:

Chamhok Mun is an enclave in the Mists with a temperate climate thirty-five miles from north to south, twenty from west to east. The domain is split into two different facets: to the north is the town of Haejong, which sits on lush, forested land. At the opposite end lies Ginjae, another town amidst a wasteland of rock and small, hardy plant life. Between the two seemingly different worlds is a massive solid wall of unknown building material measuring over forty feet high and just as thick, with an elaborately carved gate at its center.
