Has anyone ever got hold of what the other numbers in the Book of Numbers represent? We've got various applications of the 36 numbers in the list, but what about the ones that come after each name? Have they ever been linked to anything?

They were meant to show a hidden message in the Lessons in which Vivec admits to have murdered Nerevar.

How, exactly? What do the numbers reference that points this out?

"He was not born a god. His destiny did not lead him to this crime. He chose this path of his own free will. He stole the godhood and murdered the Hortator. Vivec wrote this."

"He" is Sotha Sil, as I recall.

The number on the left shows the Sermon you need to go to. The number on the right specifies the letter you need to pull out to obtain the message.

The word, not the letter.
