This is swan dive, a partially blind pegasus who's talent deals with helping animals to swim.
Name: Swan dive
Gender: Female (mare)
Age: Whatever the pony equivalent is to fourteen.
How she got her cutie mark: She was thirteen, and saw a duck-let refuse to get in the water. After coaxing it in she helped it swim, not even noticing her cutie mark until her father pointed it out to her.
really anything else: She's a shy yet fun loving mare, Although gets upset easily when people talk about her being partially blind. Her actual name is unknown and she won't tell anyone, simply telling them that she prefers this name to the other one. She grew up with a single parent (her dad) and originally worked with him on a farm, getting all the high up stubborn fruit to come down when harvest time came, and helped with clearing snow passages and such during the winter. Due to that she's a strong flier and runner, and also can swim rather well, using her wings to help steer and occasionally give her a boost.
