North is a female Arctic fox/wolf and Ski and Sled's adoptive sister.
North was adopted by Ski and Sled's family on Terra Atlas, where she was born. Her family had died during a snowstorm and she was the only survivor. Ski and Sled's mother adopted her. After their mother went missing, the three went to look for her but Mama Osprey came to them and told them she was killed by hunters. North is good-natured but very strict on rules. But she doesn't seem to be much of a fan of her friends' beliefs on humans. She has a strong bond with Cory.
Trivia:
North is named after the North Pole.
She is the only member of Nightstrike's clan to be adopted twice.
