Sisel is a Gryphon of the Valor Hall, bonded to the Valor Knight Meir. She does not understand human society or why Meir and she have to do most of what they do, but she loves Meir and she accepts that humans are different. She does not need to understand them. Just as even Meir does not understand her.
Until Sisel is asked to pluck information out of the mind of an uncooperative tortured prisoner. She does not understand what she is being asked to do, but when she touches the prisoner's feelings, she knows that, whatever else is going on, this is insane. Beyond even normal human insanity.
