How many Druid Sect, Coven Cabals, etc. are there on Hyperborea, I know I have some say in this, but as it a Keltic religion, is there only one main source in Gal which any druid must return to or are there coven being created in other parts of Hyperborea.
For Example, the Kelts in my Blackmarsh are organised around their druid rituals, and structure. But, would it be consider that they would have to acknowledge the High Druid of Gal, it reasonably close to my Blackmarsh area?
