There are a few problems with this. Firstly, you're missing a detail that shows you haven't read the rules. You're going to need to head over to the main thread and read through them. Secondly, Astaeron hasn't had a King since their last one died eleven and a half years ago - if your character became a servant nine years ago, she would have been a servant only to the previous Queen, Arianna's mother, and now to Arianna. This isn't indicated anywhere on the thread except in Arianna's bio, but that also means that no previous rulers are indicated. If your character is a servant in the castle (which is certainly allowed) then you don't need to specify to whom they're servants, only where. Though, I can't imagine kind and benevolent rulers taking five- and seven-year-olds as servants. And lastly, I'm a little confused by the last sentence of your bio in which you say that "even though they barely get to see their family they are both extremely close to them". Do you mean that they're close to their family? And why don't they get to see their family often?
Some clarification is recommended and a read-through of the rules is required before your bio can be accepted :)
