Leaf

Blizzard inspected Glacier's four pups. She mostly passed over Silver and Leaf, deciding they could stay. But Blizzard took a long time looking at Snow, turning her over to see her markings. Blizzard hardly looked at Ice at all, which could be good or bad. "Silver and Leaf can stay. Snow can stay unless we no longer have space for her. Ice must go." Blizzard spoke. Glacier nodded. Glacier was independent and she expected her pups to be too. Either Ice would learn to survive on her own, or she wouldn't, and Snow would make herself useful or have to learn to survive alone too.

Snow and Glacier were both lost in a fight with a neighboring pack. Leaf and Silver were all that was left of their family other than their half siblings. 

Blue and Leaf had a pup and then adopted a pup named Topaz who died shortly after from a snake bite.
