Castles Book 1 (1978)

From the web:

A book to help a DM/campaign judge to quickly generate and populate a fantasy castle. It contains tables that can be used to randomly generate castle attributes such as:
- Walls: number of sections, thickness, type, height, length, characteristics, defenses, etc.
- Garrison: size, technical level, morale, composition
- Siege Engines: technical level, crew type
- Leaders: level, class, race, alignment
- Followers: level, class, race, alignment
and so on.

The majority of the book is comprised of castle layouts that are mapped using Judges Guild's Campaign Hexagon System.

It was originally published as an official Dungeons & Dragons supplement in 1978 but was later reprinted as part of Judges Guild's generic "Universal Fantasy Supplement" line.

A 64-page booklet with 50 pages of maps on various fortifications, every type from solitary spires and wooden stockades to massive fortress and walled cities. These are excellent for siege, intrigue, and other adventures by the players. Included are six pages of tables for generating wall thickness, height, composition and features, towers, moat creatures, garrisons, trebuchets and other engines on the walls, retainers, servants, leaders, followers and more. The castles are mapped on light gray hex grids, suitable for changes by the Judge with colored felt-tipped markers.
