S'Larin

S'Larin was a Vulcan scientist, working in the 2400s. A bit condescending and egotistical, he was nonetheless a brilliant scientist. 

In 2409, he developed a new system of Mines to defend the Federation's Transwarp conduits. Expanding on the Self-replicating mines developed aboard 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.
