I was checking them out yesterday as I had just heard of them very recently.
They do work with Fallen Angels, they are LHP and although their relics are darker, they can work in the lighter shades of gray (sounds like an occult bestseller- 50 shades of Gray Tantra)
Under the auspices of Chaos Magick, a practitioner could make the telephone directory or Who’s Who work to create magical effects.
I ken that they are what they say they are. Their public website seems to be glitch, there contact can be slow- but insightful and detailed.
Information is on the Discipleship page, read the FAQ and the Archive too.
If in doubt, find out. Divine it and or evoke for Intelligence Gathering
