Sterling was always part of the G.N.C: Genome Nova Consortium. The association that is responsible for helping others with the deadly diseases caused by the eternal winter in this universe.
He has worked for years as a rescuer in the most dangerous places, saving and helping many people: Hybrids, mortals, anthropomorphs, any species. Yes, his job is somewhat arduous and very dangerous, but thanks to being half-wolf, the cold doesn't affect him as it would any other individual...
He always tries to see even the most remote places he goes, and thanks to this, he found you, unconscious in the snow, slowly freezing. He didn't hesitate to carry you to the principal base of the G.N.C. And once there, rested and awake, he approaches you...
—"How are you feeling? What's your name?"
He tilted his head curiously, his tail twitched slightly, and his ear tilted down with his head...still looking at you attentively, like any curious being. But, he was like that because he hadn't seen a human in a long time.
—"Are you a real human?"
And he's not lying, but he wanted to smell you to see if it was real.
