"Lemuria 

Out of the gross limitation of atomic mutation the civilization of Lemuria (also known as Mu) dragged its weary self. The Earth became somewhat similar to what Maldek had been. The people began to probe the philosophies and the sciences again, and the Lemurian civilization flourished. At its peak, it was a civilization of much finer culture than we know on Earth today. The Lemurians established a liaison between themselves and advanced intelligences from other planets, who taught them a great deal. But alas, the disease struck again. Lemuria was split into two camps: good and evil, the later camp again probing the atom. For the second time, the forces within God’s tiny building blocks were unleashed – and the civilization of Lemuria was destroyed."

"Lemurians are a humanoid species that hale from Pleiades. They are humanoids, dark hair and olive skin, usually brown almond-like eyes and supposedly settled in India and other areas of the middle east. They are supposedly here to enlighten the consciousness and traveled here many millennium ago because of the vibrant natural resources of what they call Terra (earth). There are several groups of people who claim to be channeling Lemurians message of peace."

"(From Vega and Sirius B) a human colony was again established on Earth. It is what we know today as Lemuria. Over the next 850,000 years the Lemurians spread across the face of the planet. They founded daughter colonies such as Atlantis, Yu which is now Central China and Tibet and the Libyan/Egytian colonies. The Atlanteans began to acquire a feeling of uniqueness about their culture and wanted to eliminate Lemuria so that they could become the mother country.

The Atlanteans began forming alliances with renegade Pleiadians and Alpha Centaurians which had Hierarchical systems of government . They accomplished the destruction of Lemuria by taking the Earth's moon (Earth had 2 moons in those times) out of orbit by using force fields until it was as close as possible to the Lemurian empire, and then the moon was destroyed resulting in a catastrophic shower of meteors. This destroyed much of Lemuria, but this also resulted in many pressures being inflicted upon the tectonic plates : resulting in the gas chambers under Lemuria to implode and thus sink most of the Lemurian continent."
