It seems the original links in this article were to one of Robert David Steele's web-sites. Since his death was reported these links no longer work.
I have replaced them with links to the same content on Bitchute. This means that the video content is all there but any textual content is probably missing.
This sequel is indeed a deep dive, starting in ancient Sumer and the Sumerians (of cuneiform script and clay tablets fame).
However it soon skips to 600AD and thence moves quickly on to the 1700s, about which we know a bit more.
This looks like being a 17 25(?) part sequel, of which (as of 8 January 2021 18 April 2022) 22 are so far available, so you will need to consume over several sessions.
The usual caveats apply - please make up your own mind about how much may be true and how much false - this territory inevitably includes a lot of speculative material.
