Brian... how do I say this without sounding foolish? Your character is already up to standards and operating within the boundries of the universe I put up, so part of the greater freedom I promised for this roleplay is the freedom of making your character however you want it to be - so I am reluctant to point out details about a character and say "that could be more interesting if it was different" - to me, that would be like walking up to a person and telling them how their personality, appearance and background could have been better. And now for the part where I make the least possible amount of sense... I see characters not as letters making words, but as beings that have their own minds and will and are only guided by their creators to go in a general direction. I know my characters tend to act on their own - that is when I know they are the best, and that I have truly poured a part of my soul into them. And how am I to change another being, if this truly already contains part of the soul of its creator?
That foolishness out of the way, if I had to point something out it would be that there seem to be no actual reason for your character to leave her family behind. There is a rumor that Kreshtaat is returning, yes, but those occur every so often - that is inevitable, with the Nomad's Prophecy being well over 3500 years old. All of the qualities you have described about her only makes it even more unlikely that she would leave her family behind for some quest or another - it would seem like her family would always have highest priority. A reason - any reason - would be nice, unless that is part of that dark secret of hers. Otherwise I really can't think of something.
