OP... Judging from your reactions, you're not really here for advice. You're here for butt-pats and people telling you that your character concept is totally cool, aren't you? You have a knee-jerk defensive reaction to everyone who doesn't agree with that.
Technically you can play anything you want - if other players don't like it, they can choose not to RP with you. But your character concept is so lore-breaking that almost all decent roleplayers will choose not to RP with you as soon as they learn of it.
Roleplaying is all about being creative, but limitations encourage creativity, to an extent. Taking a character who's unfitting to the game world and putting them into the setting anyway is not creative, it's lazy. You can totally play a character who has an interesting, rich backstory, and who's not just a generic commoner, while staying within the setting. You can play a character who's new to it too - just play a foreigner from far away, or someone who lost her memory. There are many ways to create the character you want without taking the lore and breaking it in half.
