Valiant Protector of Unicorn Rights
Personality: Princess encapsulated in three words: determined, righteous and batshit insane. (Batshit insane being, here, just one word.) Princess has probably read too many heroic tales of valor, because she separates her life into the following categories: heroic (herself), people she has to protect/defend (most people,) and people who are evil (anyone who is rude to her.) See also: younger female version of Don Quixote.
First Impressions: Princess is not sure of this new dimension, but she knows one thing - she has doubtless been summoned here to defeat an evil witch and save the day. Now Princess just needs to figure out who the evil witch is, so that she can lead her righteous rebellion of everything that is good and holy.
Likes: Unicorns.
Dislikes: Evil people, squid.
Fears: Squid.
Goals: Princess comes from a home world where everyone is happy and no one needs saving. Boring. Princess wants to be a hero, so she needs to find a faithful sidekick, a witty love interest, a jealous rival, and an evil foe. Pronto. And then she needs to save the day and end everything with a kiss and a happily ever after.
History: Yes, Princess is actually a princess. In the land of Moonlight, it is customary to give all princesses the name of Princess. She comes from the royal family of Meredith, who has ruled the lands of Moonlight with grace and wisdom for many centuries.
Until, of course, Princess Meredith. No one knows who to blame for Princess Meredith - was it Queen Meredith, who let her do whatever she wants? Was it King Meredith, who spoiled her with presents of unicorns on her birthday? Was it the tutor, for filling her head with silly tales of romance and adventure? Whatever the case, Princess Meredith causes daily chaos in the court, constantly challenging people to duels and insisting that various members of the court be brought to trial for unspecified offenses against honor and knightly chivalry.
Then, one day, while Princess was crying into her pet unicorn Fluffy after losing a duel against a miscreant stable boy, a strange voice appeared in her head. Would you like to experience adventure? asked the voice. There is a world that needs your help. I just need you to make a contract with me.
Well, there you go. That's all Princess needed to hear.
RP Sample: Princess reclined on a large pink pillow in the castle's library. She looked out the window at the starry night. The second moon hung brightly in the sky. With an exagerated sigh, Princess closed the cover of her worn book. In the book, a stable boy who wasn't good at anything turned out to have magic, and he was made apprentice of the most powerful wizard in the land. Princess did have talent, but there was no wizard to guide her. That strange voice hadn't taken her to the faraway land yet... I can't wait to go there, she thought to herself. I hope that all my training is worth it - I hope that I can be a good hero.
