Deepclan leader, Brindlemask's mate. Adopted father of Shadowflight, who Frost found taking shelter in a Deep cave on his warrior patrol. Froststar lost his sight in a skirmish when he was a member of the Ever-Wandering Paws, a feral cat colony that is migratory. He'd been picked up by the Everpaws as an abandoned kit, and then dropped off one summer at Deepclan as an almost-warrior age blind apprentice. Frost was bitter for a long time about his second "abandonment," but he's been able to process his feelings and even positively interact with the Everpaws when they come to stay in the north valley every summer. A cat that's quiet in a way that encourages leaning in to listen,and can be intimidating as hell when he wants to be. Seems to have "eyes on the back of his head" and always know where each and every cat in his vicinity is, despite his scarred-through eyes.
