"... DOES IT LOOK LIKE I CARE?"
Of course, everyone has heard of this guy at least once; an old man spending his life on a huge rock pillar, it has been heard he was alive 500 years ago, himself being 700, back when the Sea was known as a world of peace, vast and beautiful. Whatever you will ask him about it, he will tell you multiple stories, each of them being awful, containing death, suicide, manipulation... At his point of view, the world was messed up from the start. If it was classed as peaceful, it's because most of the people living had no incident. Other than that, he's solitary. He most likely hates you even if you never talked to him. It would be almost impossible to be classed as "a good mutual" for him.
