"This book provides a basic, modularized map of a border fort (all Kelnore forts were designed to these specifications). Since their construction, the forts have been populated by various monsters and tables are provided to put in random groups of creatures and individualize the forts on these basic designs. There are three sample forts, filled out according to die rolls on the tables, to illustrate their application. Using them, the Judge can easily create on the same basic map a different "dungeon" every time his players get together; this provides the maximum playing time with a minimal investment of the Judge's money and design time."
