I wonder what's the significance of everybody asking Jil what his after if he gets the rod. Naturally if it's only believed to grant one wish people would know, but even then it should still be kind of superficial or just to gauge how much the person is willing to risk to get it. After all, in the end all the survivors would need to fight for it with each other, except for those who wish for money and are willing to split.

However, the way people kept asking it gives me the impression they could be using that for something else. Maybe it's just to make him appear like a real hero who doesn't want anything for himself (and thus some others who want something badly badmouth him to make themselves feel better). However, seeing how the tower seems to have those two ghosts there sitting and monitoring the magics, calculating people / time, maybe there's something in the last place that will find troublesome a person who doesn't want anything, and that might make Jil's presence decisive.

Personally I think it would be more interesting if Jil didn't want anything from the rod till the end and that played a role in the conclusion.
