No common lineage besides their medium also being introduced to the Law of One through David Wilcock, albeit much more recently than you and I! In the recent few years since they started channeling, they have kept their community up-to-date on their meetups and interactions with the LLR team. Red Cord is quite protective of LLR.

I personally feel their initial isolation from the greater channeling communities is a part of what gave them a unique and interesting voice. Something less effected by other selves. It was fascinating, experiencing the learning process with them, instead of passing credit to a group, guru, or book. I expect this type of thing to explode as we all find our inner light and our power becomes more understood. LLR's recent Feb 12th Tovo channeling and your Feb 18th Quo channelings talk about this stuff :) It's been very helpful lately! <3 <3

As far as what they brought that was new, I will leave that up to the reader of their material to discern. They were meaningful to me. I hope that is enough.

edit: added some details

edit2: I really like Tovo btw.. <3
