Sartorix was a Romulan male who rose to the rank of Praetor of the Romulan Star Empire in the early 20th century. After assuming the office of Praetor, Sartorix ended the Vulcan-Romulan War and gave the sleeper agents already working on Vulcan a new mandate - to push Vulcan society to become more Romulan like so that the two races could eventually reunify.
