Question for people who have read [Full moon alchemist]

Since the story has been completed, what was the purpose of the mention of the original *person who the dragon blood is attracted to in the story? I dont think he ever made an appearance in the story apart from the fortune teller person. Or maybe he did and I missed some chapters or smt.

*Thanks perzon In the comment section, couldnt remember what I meant to write when I wrote this so I wrote uke.
