I think Nava has his own family. And this is my version of what it could be - Amaya, once a lone wolf, and now the wife of the leader, and Renee - happiness and pride of Nava. Unfortunately, fate did not give long happiness to Nava. They were killed by other wolves from another pack. And until now, Nava have blamed himself in it. Still wakes up at night with the thought of the family. Terribly misses about his daughter ... Why he chose then as the leader Alue? After all, the leader could be someone on the ice. Why? Maybe, because she looked like Renee, his daughter ... And by the way, not only Nava blamed himself, but also Niju blamed Nava and himself... Why? Look another my art)
