Garzahd wasn't really that distant, though, because he was written into the backstory of A1. He was directly connected to most of the major characters, the ones who really did have personality, so we heard lots of different, colorful statements about him.
There was very little variety in what ANYONE said about Rentar-Ihrno in the games.
And I dunno, I was pretty disappointed with Rentar's attempts to frame others. Erika wasn't a convincing villain, for the very reasons she mentions when you confront her with the 'evidence'. Neither were the dragons. It just wasn't in character.
