That may be the case, but are you going to be playing as her or her clan? Obviously they can be NPCs under your control, but nothing that matters in this new state of the world is really addressed. If her clan has survived, then so be it. But have they even survived at all? Are they doing well, have they suffered losses, have they been wiped out? 

If her duty is also to her state then she has two solid reasons to not exist in the western regions where the roleplay is currently focused. As I am left to understand it; you would be alone in a currently unfinished part of the world. I can hurry to establish the eastern regions, but that will take time and you'd still be alone. If you want to be alone, so be it, but in as wide of a world as that would create... that's stacking up to be a lot of work for me to do for one player.

But if your character was in the western regions... why? Why would she leave her homeland?
