Book of Nefertum
Spiritual book and the foundation of the belief system for the Bedrosian people.
The Book of Nefertum was believed to have been left behind by Nefertum (believe to have been a Goa'uld) before he left his people. It teaches that all life was originally created on Bedrosia, and rejects the Optrican belief that civilization was brought to Bedrosia through a portal from another world.
New Ground - SG-1 arrives through the Stargate in Bedrosian territory where the Book of Nefertum is the primary belief system -- making their presence a threat.
