Kalir is an intelligent person who appears to Gerosin periodically to taunt/offer clues about his father. Their first encounter was at a coast of the Drath continent. Their second was when he appeared behind Gerosin and eavesdropped on his Heart to Heart conversation between his mother. He then informed Gerosin that his next destination was at the Drath Records if he seeked information about his father. He also met Gerosin most recently in the Plaroa Cavern. All of this is from Chapter 5.
