While on a bear hunt with Livia and a draco stryx named Blue Moon, Blue encountered and brought down (with lots of teamwork) a spirit bear: A black bear with white fur. The creature revealed itself to be the spirit Nagruk, who had been testing her in the guise of the bear. As a sign of his favour, he bestowed a gift of the bear's pelt to her, before promising that he would watch her career with great interest.

Livia later had the pelt fashioned into a cloak, which Blue still wears today.

At some point, Blue Christmas meets Livia, a humanoid cat who works primarily as a big game hunter and occasional daredevil. The two bonded over time, and while Livia has never actually ridden Blue, as she has a mount of her own, Blue would trust Livia with her life.
