Maybe Freemasons which Descend from Templars who excavated Solomon's Temple in Jerusalem discovered something scandalous.

Maybe they discovered that Israel was never there. That Israel was actually in Tartaria. That the entire foundation of the Vatican was a Roman cover up and revision of history? The Templars found proof of this somehow, and the Pope in exchange for their silence agreed to give them limitless power and be a nation unto themselves.

This is why the Masons are obsessed...

Freemasons descend from Great Tartaria, and their secret aim is to restore it worldwide.
