- All is not well on Terra...
- Admiral Kirk and the crew of the Enterprise are en route to Terra to face court martial proceedings for their actions in Star Trek III: The Search for Spock. The Klingons are demanding custody of Kirk for his part in Genesis while the Genesis controversy rages unabated. And an even more catastrophic danger has materialized to threaten the very existence of Terra.
- The Star Trek IV Sourcebook Update contains all the information needed to bring your Star Trek: The Role Playing Game campaign up to date. It discusses the opinions of the Klingons, Romulans, and different factions within the Federation regarding Genesis and contains essays about Operation Armageddon, a Star Fleet computer simulation detailing war between the Federation and the Klingon and Romulan Empires. Sections describe what can be done to prevent the unauthorized use of starships and what sort of military justice the Enterprise crew will face when they return to Terra.
