Redclaw was born into a pack other than the Moonpaws (Silver Fang Legend Pack), and when they found that he carried some unusual mutations in his blood, they cared for him specially, and then Moonstar visited the pack, she saw him. She asked about him, having an unusual feeling, that he was not what he seemed. The pack then told her about his genes, and she offered a fair price, and a guarantee that he would be cared for. They agreed. Redclaw was sorry to leave his birth pack, but was excited about the new pack. He has settled in well, and now thrives with the Moonpaws
