“”Some believe that Atlantis and Lemuria were around partially at the same time and that the more scientific-rational group inhabited Atlantis, and Lemuria had more individuals that were more artistically and spiritually inclined.
|—The official FAQ of Lemuria|
Lemuria is a non-existent "lost continent" in the Indian Ocean. It originated as a scientific hypothesis trying to explain the distribution of some mammals, but was later appropriated by purveyors of woo (apparently, each major ocean needs a sunken continent). As a scientific hypothesis, it was made obsolete by plate tectonics and continental drift. As an occult meme, it will likely continue to exist until Homo sapiens becomes extinct, though it is not as popular as Atlantis.
Lemuria entered the woo mainstream through the writings of Helena Blavatsky in the 1880s. Since then, it has attracted woo of all sorts, ranging from aliens to New Age claptrap. It is called Lemuria because apparently lemurs lived there, and this is all being suppressed by the Vatican. This all ties in with Easter Island and Edgar Cayce in a trainwreck of nonsense.
Ramtha is supposed to be a Lemurian warrior.
