Crimson Banner Executioner
Crimson Banner Executioner is a canonical Exalted signature character detailed in Scroll of Exalts. In my chronicles, he is the Gold Faction "handler" for the Bull of the North. The Bull of the North has already slain one Sidereal, so Crimson Banner Executioner was chosen due to his propensity for wearing the First Age Artifact armor, Crimson Armor of the Unseen Assassin. Only from the safety of fate-induced invisibility does the Gold Faction feel comfortable observing the Bull's actions. The Chosen of Battles doesn't speak to his primary sponsored Solar, but he does try to arrange things to happen. The Gold Faction has no desire to lose one of their own at the Bull's hands as the Bronze Faction did.
Crimson Banner Executioner is at odds with his fellow Gold Faction Sidereal, Five Hearts, as to the direction of future relations with the Solars.
