She couldn't handle being associated with a kingdom whose rulers ran the kingdom with unfair bias and brutality, so she had to ran from it. She took off to get as far away from the kingdom as possible, and is still being looked for by the people running the country.
She traveled a lot 'till she found Jupiter and Saturn and they let her live w/ them in their castle. Space dads ;0
She seems bored/ sad a lot of the time, but it's mostly due to her just being tired 24/ 7. Paranoia makes it hard for her to get sleep. However, she cheers up a great deal around people she knows. She tries to keep her true name hidden, but if she trusts someone enough she'll let them know who she truly is. Her kingdom isn't well known, but it's better to be safe than sorry.
