I just came across wizard's keif(a town on some cliffs, by a coast, in a level 15-20 human zone, it's inhabited by elementals and has a vista on the cliffs, and a skill point for fighting a fire elemental), is there any way to reach the giant, flying castle in the water near it?, From what I've seen so far, it doesn't seem to farfetched that it could be reached.
