OT III
Extracted from the Wikipedia article Operating Thetan.
OT III, known as the "Wall of Fire", is the most widely discussed level and contains Scientology's account of a catastrophic event 75 million years ago involving the Galactic Confederacy. OT VIII was released after L. Ron Hubbard's death and is the highest level offered. Scientology publications list additional OT levels beyond VIII, but no authenticated content exists, and former senior officials state that Hubbard never produced material for higher levels.
