Savar was a male Vulcan, born in Earth year 1824, who became one of Vulcan's most respected space explorers. In 1875, he wrote the precepts that would form the basis for the creation of Vulcan's Offworld Service, of which he would become the first Prefect. Those precepts, which also came to be called "Savar's Prime Directive", posited that the sociopolitical implications of interfering with any alien society before they were ready, even by revealing their existence, was too grave a risk to assume. This philosophy was often expressed by the axiom, "Destruction before detection."
