What is 'The Order of the Bear'?

The 'Order of the Bear' is a secret society established in the times of King Arthur. They believe that Arthur and his Knights will reincarnate to bring the world out of turmoil. The group is so secret that a fiction writer had to expose and popularize them. That way, nobody would actually believe that they are real, which would erode their element of surprise when the reincarnation happens.
