Here's the SU. Sorry the appearance is on the short side... I honestly ran out of aspects to describe. Anything I'm missing?
Name: Cacia (pronounced kay-sha)
Age: Unknown
Race: Korok
Appearance:
Only one to two feet tall, Cacia is one of the smaller Koroks. Her wood-like body is a pale yellowish brown, tawny color, fairly smooth with a subtle bark-like pattern. She has a sturdy build for a Korok, somewhat more round than tall. Like her fellow Koroks, she has short arms and legs, and she weighs very little, which allows her to fly for a short time by means of a small Deku leaf sprout. The mask-like leaf over her face is deep green with a hint of yellow, giving her an appearance of perpetual springtime. Her features give her a generally calm appearance: two round eyes, a wood nose poking out through the leaf, and a mouth that usually turns up at the corners. The leaf itself is oval-shaped, tapering into a very slight point at one end while the other is more rounded. It seems to be very slightly askew, the pointed end not quite in the center between her two ears.
Personality:
Cacia is generally optimistic, and from her point of view, the world has some beauty to it even in the darkest of times. Though she knows her share of sadness likely waits in the world ahead, she isn't one to despair for long. She dislikes darkness (both literal and metaphorical) and conflict, so she tries to find compromises whenever she can. Due to living in the Kokiri Forest for her entire life, there are some things of the world that she has yet to understand -- problems that may be, or at least seem, much too big for a little Korok. She sometimes struggles with accepting herself in her new form, because she isn't certain that she's still herself.
Despite her small size, she holds herself up straight and does her best at whatever task is set before her. When something needs to be done, she'll make sure it happens even if it means doing it herself, though she'll gladly stand down if there's someone else more qualified for the job. "Plucky" is a good word for her: she can be extremely determined and won't give up easily despite difficulties that may arise. She is not terribly headstrong and will think through a decision before fully committing to it. If someone needs help and she's able to give it, she'll do so gladly. She loves to be useful and hates the feeling of being unnecessary or unwanted.
For the most part Cacia is a friendly creature, although being transplanted from the Kokiri Forest out into the rest of Hyrule has caused her to become a little timid. After all, everything and everyone are suddenly so much bigger than she is. Even so, she's willing to try a few new things if they don't seem too scary, a trait helped along by her faith in the general goodness of people. She can be loud to an extent, but only when she really wants to be; she finds it difficult to do so as a Korok and usually doesn't care to make much noise. By nature she has a somewhat simple, childish point of view, but she won't let that or anything else stop her from doing what she feels is right or that she has to do.
History:
The Kokiri Forest was Cacia's home for as long as she could remember, and as far as she's concerned, it's been a very long time. Originally a Kokiri herself, Cacia had a fairy companion by the name of Somi. Cacia lived simply and peacefully with her fellow Kokiri, content with her life in the Forest and seeing no need to stand out. After many years, however, something changed.
One day Cacia became a Korok. She didn't know how it happened or why, just that she had become something different, something that wasn't a Kokiri any more. And something, maybe someone, had done it, but she didn't know who that something or someone might have been. She was one of the first Kokiri to become a Korok, and for a while no one really knew what to do. Some of the Kokiri stayed away from the Koroks, a few ridiculed them, but neither reaction lasted long as friendship quickly became the order of the day. The Koroks were old friends in new forms, and so nothing seemed all that different as far as life in the Kokiri Forest went. Cacia and her fellow Koroks gradually became used to their new forms, though it wasn't necessarily easy, and continued to live their peaceful lives. Yet more and more Kokiri became Koroks, and none of them could figure out how it had happened or who had done it.
News of the Koroks had apparently reached Princess Zelda, for a letter arrived summoning their greatest warrior to Hyrule Castle. The Koroks knew essentially nothing of fighting, so in their terms "greatest warrior" meant "the one who could possibly fight a little." In other words, Cacia. After determining that leaving the Kokiri Forest would not in fact kill her, she set out for Castle Town, deciding that she would be honored to accept the role into which she had been thrust.
Password: Triumph Forks, of course.
Other: When Cacia became a Korok, her fairy companion vanished. Cacia doesn't really know what happened to Somi, and she misses her. Sometimes she thinks she feels Somi's presence, lending her strength from inside her very self, but she often wonders if it's just her imagination.
RP Sample:
Leaving the Kokiri Forest was a scary thing to do. Very, very few Kokiri had ever been out of the Forest, if any. It was said that a Kokiri who left the Forest would die, and so none of them were inclined to do so. Of course, Cacia knew that leaving the Kokiri Forest wouldn't kill her, because she'd done it. Or maybe that rule didn't apply to her any more. After all, she wasn't a Kokiri any more. She had a new name now: Korok.
But that didn't make her too different, did it? She was still Cacia, wasn't she? Cacia the Kokiri and Cacia the Korok didn't have to be so different. Maybe Princess Zelda knew something they didn't, that a Kokiri or Korok could leave the Forest and still be all right. Princess Zelda... Cacia wasn't entirely sure how she'd ended up where she was. All she really knew was that something had changed, and not just in the Kokiri Forest. Out here, it was more than just different like it had been back home. Whatever it was, it was decidedly bad.
And it was dark. Cacia didn't like dark. She was used to warm, cheerful sunlight by day and calm, silvery moon- and starlight by night. Not these dark, foreboding clouds. But more than she felt scared, Cacia just felt very, very small. She shrunk back. Even if she was still a Kokiri she might have felt little, but now...
No. Cacia straightened herself up determinedly. She wasn't going to think like that. She didn't know what she could do, but she was going to do it. If Princess Zelda needed a Korok, she would come. And that was that.
