Hello. I've obtained enough marbles to buy Maze Rune 094 (500 marbles) from Chatnachoq. However, when I select to view the section of his ship which contains this rune, he says "You're a nosy one, ain't ya? Ain't nothin' for ya to see here!" I've searched the Wiki and Google extensively, but have not been able to find any indication of a prerequisite for purchasing this Maze Rune. Does anybody happen to know what I need to achieve in order to be able to purchase the rune from Chatnachoq?
