The simple fact is that there is almost zero surviving knowledge of the real religious traditions of the 'Druids' or 'Celtic Pagans.' The information simply isn't there, aside from a few lines written in Caesars Conquest of Gaul.

Gardner took an empty void and built a tradition out of it, but all roads lead to him.
