I have done all but two quests one being Diabolos which is in the mine and requires the 11 key... which i found out antlion is a prerequesite for this. But i never accepted or ever heard of the antlion quest and it is not in my hunt log at all and not available on the hunt board. Is there a prerequesite for the antlion hunt?!?!?

He's an elite mark. Talk to Montblanc. If he isn't available, do all the available elite marks since it sounds like you haven't done any yet.
