He nodded to her answer to his question, but soon focused on the other thing she said. About the undead that werent under her control. She spoke how she is seeking them out to study them about why and how they persist
"Hmm. Well I have heard of some things about that. Those with remorse and unfinished business tend to be in a more spiritual form. Those that are incredibly mischevious and are unable to move on become what the Boscan people call a Poltergeist. Though in regards to those undead with a more physical and corporeal form like zombies or the icebergian draugr, I have read a study back at my home country about the power of emotion. Emotion keeps the undead at our world. But for those more mindless undead. It is Agony that keeps them. I cannot remember the name of the author. But he wrote how he believes that agony has a greater energetic radius and power than any other emotion. And has done numerous experiments to measure, capture, contain, and study the leftover emotion embedded into objects that were near a tragedy and even corpses. His work is focused on a hypothesis that you can take a saturation of agony, add any kind of intelligence even an artificial one from Talaz Lagaar and they will combine together to transmute the energy of emotion into the energy of physical action. This, he believes, is what explains what people call 'haunted' objects." he chuckles "Truly interesting. But I do not know if anything is true. It is not like I verified it. But I do agree. Agony is the strongest emotion"
Pain physical pain is the only emotion you cant fake. People can fake happiness, sadness, indiference, anything really. Thats why you have career choices like acting. But get cut or stabbed and they will scream and cry out in pain. Same with emotional pain and trauma. People can get praised a lot, but one insult to your pride or feelings or one mistake that haunts you. That will hurt and overtake anything good. Negativity is power. Agony is the greatest emotion a human feels, be it physical or psychological. He does agree. It is the purest and rawest emotion of a living being. And if its true, even the undead. Truly an incredible thing.
Makes him wonder, was the book he read written by an evil necromancer or a neutral and studious mage
