Ramtha is an entity that JZ Knight, an American self-claimed spiritual medium claims to channel. According to Knight, Ramtha was a Lemurian warrior who raised an army and fought against the tyrants of the times, the Atlantians, over 35,000 years ago. Ramtha led an army of over 2.5 million across the continents, conquering 2/3 of the known world, which was going through cataclysmic geological changes.
