Idea for a new character

So I want to bring in a new character that's not adopted (it's been many years since i've made my own real character lol) and I'm looking for plots/ideas/etc that could help me shape them a little bit before they come in since I'm not totally sold on something yet.

They're going to be roughly a year old and I haven't decided between male and female yet. The idea is that they're from a kingdom (overdone i know) and the child of the king/queen but they were adopted. The heir to the throne due to being the only male/female of the litter (depending on which gender is picked), however they were adopted by the queen while the king was away (he wasnt around for the birth, away on some mission) and the Queen never told a soul. Raising the kid to be an heir, somehow it broke out that they were adopted and things happen and now said character is running around Ardent (be it angry that they were lied to, dont know who they are and want to find out, who knows yet).

I'm not looking to make an overly evil character, but I'm not against having another baddie, although I'd like there to be some good in there. On the flip side, i don't want an overly angelic character either.

I'm mostly looking for wanted characters that could be filled with a new one and how that can help me create a new character. Whether its looking for a mate or a healer or both, I just want some ideas to bounce around and try and run with. Of course, there will be plenty of threads for the winner idea/s I go with!
