Lelar Prime is homeworld to the Lelari.
In order to avoid detection, the Lelari erected a large cloaking device that enshrouded their planet, which has been in service for centuries.
In 2367, the USS Galaxy discovered the whereabouts of Lelar Prime. The successful first contact led to the Lelari opening up their planet to a limited amount of talented visitors, whom they were allowed to pick and choose.
Benjamin Caldwell was stationed on Lelar Prime from 2367 until 2372 as a cultural exchange officer. In 2372, Dr. Helena Bourget, member of the Arkrand Society, was also living on Lelar Prime. (Star Trek: The Cantabrian Expeditions: "Catalyst, Part One", "Catalyst, Part Two", "Breaking Benjamin")
