Five Hearts
Chosen of Serenity. The Gold Faction "patron" of the Solar Circle from the Hundred Kingdoms chronicle. She has major disagreements with some of the more militant Gold Faction members who support Solars like the Bull of the North, including the Crimson Banner Executioner.
Five Hearts is not a canonical character.
UPDATE: Five Hearts has been part of my Exalted chronicles since First Edition. When I was rereading Gracious Shaia recently in the Manual of Exalted Power: Sidereals, it suddenly occurred to me that the two could very well be the same person. Gracious Shaia did not appear until Second Edition, so obviously this would be a retrofit on my part. This would involve making Five Hearts into one of Gracious Shaia's resplendent destiny guises.
