Senator Pardek was a member of the Romulan Senate with a lengthy career in Romulan politics. He had been in public service since he was a young man and as of 2368, a senator for nine decades. Early in his life, Pardek was present at the Khitomer Conference peace talks (2293) between the Federation and the Klingon Empire.
Pardek was considered a man of the people and had sponsored many reforms. Reportedly, Romulan leaders considered him as somewhat of a radical since he had been an advocate of peace throughout his career. Pardek represented the Krocton Segment, and maintained a dwelling there; he visited on the third day of the Romulan week when the Senate was not in session.
In 2368, Pardek (along with co-conspirator proconsul Neral) attempted a takeover of Vulcan. After spending decades building a reputation as an advocate for peace, and supporting Vulcan-Romulan reunification, Pardek lured Federation Ambassador Spock to Romulus for false reunification talks; secretly, he had launched a Romulan invasion fleet to Vulcan. The plan was foiled at the last minute by USS Enterprise-D Captain Jean-Luc Picard and Lieutenant Commander Data. (TNG: "Unification I", "Unification II")
In the novel Sarek, in 2293, at a peace conference at Khitomer, Pardek is sent as a representative of the Romulan Empire, and introduces himself to Spock at the talks. He expresses interest in the shared history of Vulcan and Romulus and even suggests the possibility of reunification. His first meeting with Spock is depicted in the novel Assignment: Eternity.
His mirror universe counterpart appears in the novel The Sorrows of Empire. As a young senator in 2288, he is one of the few people to realize that Template:MU's long-term plan is to significantly weaken the Terran Empire so that it will be conquered by outside forces. As with his primary universe counterpart, his first meeting with Spock occurs at the Khitomer Conference in 2293. In contrast to their counterparts, however, this proves to be their only meeting.
