Shiverburn is a pale brown tabby she-cat with black stripes, bright blue eyes, and a scar under her left eye.
Shiverburn had always wanted to be Gustclan's medicine cat since she was a tiny kit in the nursery. She would watch Cometdash sorta through herbs, and memorized them before she left the nursery. When she reached her sixth moon Miststar made her medicine cat apprentice. She wasn't apprentice long until Cometdash retired due to an injury and old age.
