Have you decided wheather or not you want her to be a servant of the castle or to the princess? Perhaps she does something that gets her bumped up to tending to the princess. Then it might be a bit easier to slide your character into the main rp. Or if the two had always been friends then she might even go to her for advice on it all... 

OR

What if the Princess tasks the servant with help of leading the tournament and challenges?

Not sure if any of those will actually help. But just ideas that popped into my mind.
