Caprica Terminal is a space station and transit hub orbiting Caprica during the First Cylon War.
The first signs of IDRIS interference near Caprica Terminal occurs following the delivery of Jupiter-class battlestar Athena to Picon, forcing Daidalos and her small support group to jump to Caprica to deal with the interference by destroying nearby compromised satellites.
Later, Clothos returns Galactiac and her surviving crew, including Praetor Samanta Agathon and excluding Admiral Jubal Sarkis, to Caprica Terminal.
As Colonial Fleet recovers Galactica there, this leads to the Battle at Caprica Terminal (Battlestar Galactica Deadlock).
