How about something like The Doomsday Coalition or for short, TDC, or maybe Doomsday Seekers, I can't concentrate very good at the moment, I will let you know if anything comes to mind. So far, these two are the only two I can think of, and the names would fit well for the beliefs of this time period.
Thanks, I will try to think of something else that's more suitable for the terrorist group. that sounds like it will be a very interesting book. I hope it sells well. I just thought of one The Doomsday Soldiers or (TDS) , I love to write so kicking ideas around is fun for me.
The Doomsday Elite (TDE)
