In their dealings with the Occuria, the concept of free will is brought into question. The Occuria have kept a tight control over the world, ruling from on high at the Pharos for countless years. Through their guidance, they have seen the rise and fall of several kingdoms. Princess Ashe and the other members of the party are presented with a choice: They must either go along with what the Occuria wish and save the kingdom their way or forsake their advice and forge their own way. However, if they do choose to break ties with the race that they never knew was so ingrained into their lives and society, they face the risk of having the kingdom fall as a result, not to mention retaliation, due to the fact that the Occuria are a very proud race and always deem themselves in the right. A similar state of being in reference to the Occuria is presented by Campbell in reference to the Sumerian empire:
"The holy spectacle of the Royal Tombs of Ur, where the entire court of the dead king descended alive into his grave, tells of awesome, noble impersonality of lives lived thus, in dedication to a priestly play: a mythological play, performed in honor of heaven's law, derived from observation of the mathematically measurable cycling of the moon, the planets, sun and stars." (Creative Mythology, 576)
The Occuria play the part of that dead king who callously look down upon the lives of those they "rule over"; they are essentially watching a grisly and mythological play that they direct from beyond the reach of mortal men, derived from their own interpretations of what is right and wrong.
The characters of the play (or game) come to realize they are merely players in a pre-conceived notion of life. However, they also realize that they have a choice: yes, one that could possibly destroy them in the long run, but the knowledge of a choice is present and they take it, proving to the player that one can always make a choice in a given situation to decide to either go along with a consensus or forge their own path.
One other major aspect that often comes into play during the course of the game is the moral standpoint of teamwork and doing what is right for the majority of the group (or in some cases, one's entire nation). Ashe could not possibly have attempted to reclaim her throne without the help of others: She requires the military might of the Resistance force and the cunning of Prince Larsa in order to allow herself, at the very least, a slim chance of being able to reclaim what rightfully belongs to her.
However, this presents the opportunity for supposed betrayal, as one of her former retainers, Vossler, turned her back over to the Archadian Empire at one point in the journey because he was promised the safety of Dalmasca as a whole (unfortunately, he was double-crossed and executed as a result). So while there are overall themes of doing what is right (while still maintaining a sense of a boundary that should not be crossed), the strong overlying theme trying to be presented is the concept of choice and Fate, and that everyone has both, though some situations may be a bit more dramatic than others.
