Log Entries:

  • "Captain's log stardate... unknown. During an ion storm the landing party has beamed back to the Enterprise and found it and the personnel aboard changed. The ship is subtly altered physically. Behavior and discipline has become brutal, savage."
  • "Captain's log, supplemental. I command an Enterprise where officers apparently employ private henchmen among the crew, where assassination of superiors is a common means of advancing in rank."
  • "Captain's log, stardate unknown. We are trapped in a savage parallel universe from which we must escape within four hours or I will face a death sentence at Mr. Spock's hands."



Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
