"So we know that Renarin seems to have a special place in the Diagram, and Odium is unable to see his part in it."
May I ask for the source on this?
I've read the exchange between Odium and Taravangian and my first thought was "Odium put that there just so T would find it, think he has an advantage, and make a bad deal."
Is there some other reference for Odium's inability to see it outside of a vision Odium set up on a day when Taravangian was below average?
