Update: Okay, due to much pestering(just kidding), I put in a lot more backstory, and provided more information on what the letters said, who the Gods were, what happened during the war, and why Edamus couldn't show the originals to everybody, etc. I hope this seems a bit more polished.

A culture has it forbidden to say their rulers name under penalty of death. Anybody in power must be referred to as their title. Comes from the fact that the rule or position can be taken over by anybody from any level in society. To use the title elevates them or brings them down from whatever level they were originally at before they took the position. Respect and authority comes from the position, not from previous life.
