Eiron the hermit

Gemma Squarecut

You could also have a chat with Eiron, he's so old that he must have knowledge very few others possess. However it would undoubtedly be very hard to convince him to share his information with you. Some people say he's a bit strange but, having met him, I can say that "a bit" is putting it mildly. Still, maybe you'd be able to squeeze something relevant out of him.
