Fastúlfr is the son of Eyja and Styrmir, and is the brother of Värna, Itâraĸ, and the deceased Rádala.
Level-headed and possessing an incredible ability to keep his cool even under the most stressful circumstances, Fastúlfr is everybody's friend. Even as a pup he never snapped, bit (excluding prey and when given explicit instructions during training sessions), growled, cried, or complained. This makes him both very easy to get along with and, by some accounts, supremely boring.
He'll always feel sad about his sister, born with unusable hind legs and unable to survive her puphood. Sometimes he thinks he sees her in his dreams. His best friend is Jaqar, and while the two couldn't be more different in terms of personality, they've always got each other's backs.
