Secrets of the Ancients - GM question


I have read all topics about this campaign and wiki and some other sites but didn't find an answer.

Can someone tell me what the
League of New Thought

It is mentioned four or five times but there is no explanation what they do or what it is. Knowing my players they will ask for it and I wouldn't blame them as it looks as important piece of lore.
From what I can see, it is a Droyne faction from 300k years ago that opposed the Droyne Empire. One listing says they have access to the formula to create Super Droyne (Sons).
