A young filly, perhaps 12 years old. Her coat is white; her mane is unkempt, and consists of two shades of red. Her tail is boyishly short and sports the same colors. Her eyes are cobalt blue. She usually wears a pale green stetson hat and has a determined look on her face. Her cutie mark is a compass rose circumscribed by a heart shape.
Wildheart is Stronghold's little sister. Their parents, in Horseshoe Bay, have sent her to live with him for a while.
