do you mean Duri'naan? I think you might be confusing them with Valko, Nathanael reveals somewhere around the second or third chapter at the campsite that Valko no longer lives in the shrine. im pretty sure he'll appear somewhere in the later chapters or as an endgame but Duri isn't really meant to be insane/unstable ? Sorry if it came across as rude ik this is an old comment it just stuck out to me
