The FDRF 39 situation.
The exact outcome of the mission is not certain, as it was in the hands of the RPG player whether or not the situation could be satisfactorily resolved. The date of the incident was not derived from the original RPG source, but from the FASA RPG module: Star Trek IV Sourcebook Update.



On the Mitch O'Connell painted cover, the Federation starship shown is number NCC-1702, the registry that the FASA Corporation Star Trek: The Role Playing Game assigned to the USS Potemkin in the Federation Ship Recognition Manual. The introduction of the story indicates gamemasters and players may choose to use any suitable starship, Potemkin inlcluded. For the purposes of the wiki, and based on a later annotation in Star Trek IV Sourcebook Update, the Enterprise is considered to have been the vessel to investigate the vanishing station crew. Indeed, on the David Deitrick cover, Hikaru Sulu and another Enterprise lieutenant are shown, as well as the Enterprise herself.
