Tri Sovereign States:
This is a primer I've compiled for anyone who is interested in looking into The Tri-Sovereign States and the history behind it, along with esoteric/occult history.
But you have identified them as a key root bloodline above, what is the difference?
They were a root bloodline but they effectively were killed off. It would be intellectually dishonest for me not to include them as a root. You need to branch off the bloodlines to see who exists as a Venetian/Black Nobility line today. Hope that clears things up.
I appreciate that answer
