A fantasy supplement for use with the Game Engine Manual
From How to Use this Book:
This is the first Writ of Monsters book, a guide of creatures for use with the GEM role-playing system. This is a tool for Game Master and player alike, giving the ability to each to play out the Draconians of Krynn for their fantasy campaign.
From What's Inside:
While this book obviously centers around the Draconians of Krynn, it focuses more heavily on how they can be included into existing campaigns, rather than just their statistics and abilities.
