My personnal experience with NOD was not one with a happy ending.
In the end, their chief and I had arquements because he letted politics visions into his explanation. By this I ment the 140 anti groups I received each day. That aside, I do their course in combination with OBOD one. I have to admit , the course they offer is quite good, and for me then, is a nice add on to the OBOD course! I can only recommend reading through thier course, but I feel a better connection with the animalistic vision of OBOD in our rituals then the wicca led callings in their rituals. But this is personnal taste offcourse.
Indeed, they are a young group and many meetings is about seeing a video about some celtic knowledge. Their leader is a walking library about celtic historical knowledge and has written a few books about them as well. The course was written from some irish person I never met, which I believe is very nice too! I love the in depht irish druidic view. But then again, I use it only to spice up my OBOD course!
The NOD group rose from a video they somehow received from the last druid or something like that. I do not remember quite the details anymore, since I broke up with them a little over a year now.
Another reason I didn't like them performing open rituals is because media is a way of drawing attention to their group. Something I cannot cope with personnally. We all like attention, but to call in local television is abit ... over the edge for me . Again this is personnal thought.
All in all: take the course, learn from it, and when you feel ready to contact OBOD about your course: look back and make them entwine into your personnal course!
Words, mere words, Vivid, clear and sometimes Cruel!!!
Yet ... they have a subtle magic in them.
