S'Larin was a 25th century Vulcan scientist. A bit condescending and egotistical, he was nonetheless a brilliant scientist. In 2409, S'Larin developed a new system of mine technology to defend the Federation's transwarp conduits. Expanding on the self-replicating mines developed aboard Starbase Deep Space 9 in the 24th century, his mines could distinguish between Federation and Romulan starships by detecting a trace mineral only used in the construction of Starfleet ships. The mines also had an artificial intelligence more advanced than that of most starships. (STO mission: "Minefield")
