In 2368, the Krocton Segment was represented by Senator Pardek. Pardek maintained a dwelling in Krocton; he visited on the third day of the Romulan week when the Romulan Senate was not in session. He also had family in the area, including one that was a legal intercessor.
That year, Federation Captain Jean-Luc Picard and Lieutenant Commander Data visited the Krocton Segment as part of their undercover attempt at making contact with Ambassador Spock, who had aligned himself with the Romulan underground movement operating out of nearby caves.
