Nice, I can't wait to see how that character comes to life. Perhaps he can be found in the castle as a stone statue that requires you to get the sword you find in the ocean. After all, his sword is the key to freeing him. It needs to be unequipped in order to use it to free him. After that he'll be indebt to you and do whatever you want him to do. It would be cool to see a character like that. This is mostly just ideas.
