Project Tapestry was an operation conducted by Starfleet Intelligence in the 23rd century with the aim of conducting surveillance and infiltration of the Romulan Star Empire in order to determine its internal political structure. It was classified as SECLAR 6 and headed by Captain Slavit.
Starfleet Intelligence agents that were assigned to this project were also tasked with finding means of undermining the Romulan government either through infiltration or subversion. Their assignments included interrogation of free traders along with any other individuals that had contact with the Romulan Star Empire. They also monitored subspace transmissions in order to gather further information as part of their assigned duty. (FASA RPG module: Star Fleet Intelligence Manual)
