Eamon Designer's Guide
The Eamon Designer's Guide is document created by NEUC president John Nelson that gives guidance and instructions for designing new adventures. Nelson first describes the guide in the January 1985 issue of the club newsletter:
Designer's Guide — A comprehensive guide that gives you both an easy to understand text on creating adventures and a quick reference manual if you just need to look up something about how Eamon works. It is filled with examples and includes a complete adventure design from beginning to end to show you how to do an adventure. An additional section that will really help is one that explains the 6.0 features in depth, with examples on how to use them.
In the October 1987 issue Nelson says that the guide is meant to be a more helpful reference than the Dungeon Designer's Manual, and that at that time it was still in progress. Whether the document was ever completed and released is unclear.
