Sris Lehhett was a male Fleet Admiral in the Centrality Navy. In 25 ABY, shortly after the start of the Yuuzhan Vong War, he launched a bloody military coup, overthrew Scrivinir Tavell Geen, and declared himself Scrinivir.

Although Geen fled to Coruscant to petition the New Republic for help, it is doubtful that they ever agreed, given their state throughout much of the war. Although it is believed that the Centrality tried to stay out of the war.
