Selem Bor

Selem Bor was a Trill and member of the Federation Science Council in 2339. He was instrumental in persuading the Federation Council to negotiate with the Klingon High Council to secure the necessary travel permissions for an expedition to the planet Athrak V, a planet in Klingon space.

He was also aware of and helped supervise Project Sphex, a classified research group organized by the Science Council which was tasked with researching a particular and still mostly unknown alien force.

Selem was a joined Trill, which meant that the humanoid individual contained a separate symbiotic life-form that carried the memories of previous hosts, which the current host could access. However, as of 2339, this was still unknown to most non-Trill Federation citizens. According to the naming traditions of Trill culture, Selem was the given name of the humanoid while Bor was the acknowledged name of the symbiote, though most non-Trills were unaware of the distinction.
