Shadowstar Station (SFR-721) (also known as Station Salem-One) was a United Federation of Planets facility active from the late 23rd century to at least the early 25th century, though it was briefly abandoned in the mid-24th century. (Star Trek: Shadowstar Station) The Orion Press and The Starfleet Museum continuities have Station Salem-One as the site of the Romulan ambush (akin to the Japanese bombing of Pearl Harbor) that precipitated the Earth-Romulan War.
