Decision at Midnight (Star Trek: The Role Playing Game)
From Wikipedia, the free encyclopedia

Decision at Midnight is an adventure published by FASA in 1986 for the Star Trek: The Role Playing Game, itself based on the TV series Star Trek.
Decision at Midnight is an adventure in which the player characters, all junior Star Fleet officers who attended the same Star Fleet Academy class, are assigned to the crew of the frigate USS Arkadelphia which is sent to observe the borders of a group of planets looking to become allies with the Klingons. After an encounter with a Klingon ship, Captain Ian Vellacora of the Arkadelphia starts to show aberrant behavior and suddenly announces he is blockading the planets, preventing Klingon ships from visiting. With a Klingon relief force on the way, the players must choose whether to support the captain despite his increasingly bizarre behavior, join a group of crew members opting for mutiny, or find a third path.[1]
Although players can use their own characters from other adventures or as part of a campaign, this book also provides six pre-generated characters.
