The word 'fantasize' is a more complicated one than it first appears. For example, many people in boring situations, like the guards Nessiah passed every day in the castle, fantasize about being at home with their wife and children instead. This is fantasy in the 'satisfying and pleasant' notion of the word. They will, after a time that seems infinitely longer than it actually is, return to their home, and may indeed have such a sweet reunion.

The other sense of the word involves 'extravagant and whimsical' ideas unlikely to come to pass, far more so than leaving guard duty to come back home. Nessiah fantasized about Gulcasa.

It was hard to narrow it down much more than that. Certainly some of those fantasies were sexual, as most people would assume. There were far more that were plainer. Being able to sleep near him and feel protected; being able to be honest with him, to tell him what he was and why he was here, and to be accepted even with him knowing that.

These thoughts were truly 'extravagant and whimsical' notions that had no business as anything but fantasy.
