Not accepted. Lots of problems. 

Didn't I already tell you you couldn't do that sword? I guess I was a little vague. No, you can't do that sword. 

And let me deconstruct the armor too: Skystone being soft, armor made from it would collapse upon itself too easily. A good hammer blow and you're done.
Plus, the bulk of the armor you're describing would severely limit your movements, even if it was light as a feather. There's a reason why armor in real life is relatively thin. Because otherwise it would get in the way of joints, or else the joints would have to be unarmored and they'd become the weak points. 

How is she Danlith, exactly? Only by blood, I take it, [s]because a Danlith would never prostitute herself. That doesn't preclude her form having Danlith blood, though, so long as her mother was also only related genetically.[/s] Also, no pure white hair. I said they have lighter hair, like light browns and blonds.
EDIT: Actually, you just gave me an idea and added to the history and mythos of the world. During the Tharan Conquest, those problematic Danlith who didn't die in battle were enslaved as temple prostitutes. Slavery has since been outlawed by the Empire, but there's still a culture of Danlith blooded prostitutes, who now actually outnumber the free Danlith priestesses. 

Are you seriously going to tell me that she killed all of the rich people in Orunmilla? You don't think anyone would ever realize that the same prostitute everyone who died had slept with was the one killing them? And where exactly did she learn the skills to take on trained guards that must be employed in these wealthy homes? Or to fight and escape soldiers who came calling? I really hate the "super skilled, often sought after" assassin, because it really doesn't make sense, for more reasons than I've listed. 

Much of this character is problematic. I really just don't buy that she goes from prostitute to super-badass-knight-sword-for-hire. Especially without any sort of training. 

Further Editing: I'll tell you what, though. You could cut the character's history a bit short, have her be a Danlith prostitute who [i]steals[/i](not murders, I maintain that that would get her caught and executed way too fast) from her richer clientele. Perhaps, though, now she travels with Gabriel, who's teaching her the old Danlith ways. This way, you lose the parts of the character that I object to, but still manage to have the prostitute-to-warrior story that you wanted. What say you?
