Princess of the Water Kingdom, Katelyn is incredibly caring, always putting others first and her own well being last. She has fallen unconditionally, irrevocably, in love with Earth Kingdom exile Jiro Katai and is pregnant with his child.
Katelyn is bright and cheerful most of the time, though very shy around strangers. She often lets herself care too much, and can be easily drawn in by people. She loves to read, write, and sing in her spare time.
Katelyn can manipulate water, so if she needs a weapon she will usually create a sword; made of ice and a special covering she designed herself to increase it's strength.
Katelyn was born in the castle, and has been a princess all her life. Yet she is not spoiled in any way, putting others well being far beyond her own. She helps commoners in any way she can, and beleives that she's nothing special; just lucky.
