Are you using a duplicated one? You don't really have to put it down prior to the quest. It doesn't give you anything extra because the first time around (unless you're in NG+) you have to walk there anyway so it's pointless to put it down prior to the quest.

Best thing to do in this quest is to battle the griffin in the Estan Plains and then walk to the Blue Moon tower. When you finish the quest at the tower go back outside and put down the Port Crystal then. This is for another quest called The Wyrmking's Ring for which you will need to travel back to the tower later.
