The guy is - by the way - a hint towards a jolke of the very first Divinity game. In it, there's a trader selling stuff for 500 Gold.
And this is - as so often - another hint ... In all Divinity games there are several NPCs named after forum members.
Like that trader from the first game.
He ist still in the forum, and at one point during the development of the first game a kind of insider's forum-joke evolved that if he sells anything, he wants exactly 500 gold for it.
So, the NPC from Divinity 2 is kind of an echo of this trader from the first game.
And the kinds of stuff he sold.
