Shadowfrost was a muscular, black and white tom with a mask of white splash across his eyes and light green eyes. He was the father of Angelfrost, Graypaw, Moonpaw and Kestrelwing, and his littermates were secretly Stealth and Rowanflame.
Shadowfrost was doing border patrols, having a fight with his mate. Shadowfrost barely noticed his kits, and did not talk to them much. But then one day, as he was hunting alone, a dog struck him on the neck and he died instantly. His family mourned over him.
