[Source] King Demavend III was the ruler of Aedirn. For many years, he participated in an ongoing dispute with King Henselt of Kaedwen over the Lormark. As a ruler he was known for being rather cruel and envious, but also quite intelligent and knowledgeable about the tactics of war. He was, for example, able to predict Emhyr var Emreis' moves during the war with Nilfgaard. He showed little or no regard for the pain or suffering of others and had a particular hatred of elves.
