The datas you retrieved are very interesting. Most are already into Marie's memory.
You had a good intuition, the Agnus Dei project used pictural and musical tools to mold the personality of the first subjects. The few survivors of the project kept the reference and the name of the original project to form the organization you heard about. And i am one of them.
But what we found through the enlightenment take us on a different path, although the most important value remains in one of the three cornerstone : Devotion. People say sacrifice...

There is a musical movement that remain in my head. Search the data sound "Agnus Dei" in Faure's Requiem. Listen it in a peaceful place and maybe, you might be suprised.

Your curiosity is the quality that will drive you to the perfect understanding of what we are.
