Chrono came from a large pack of loud-mouthed, self important wolves. Being the runt of the litter, he and his opinions got pushed down and ignored by everyone, making him a fairly quiet wolf. Because he was constantly listening instead of speaking, he noticed long before the other members of his pack that the pack was breaking apart, and being the emotional, impulse-driven child he was he just left without saying a thing and of course got lost.
After much struggle with food and housing, especially in the harsh weather of the mountains, he somehow managed to live and survive. Then came the great idea of starting a pack!
He met Viaa while trying to find an empty territory within the mountains. Viaa’s pack was falling apart as well and after meeting with her in secret a few times she agreed to go with him, and tried conving her siblings to come as well. Her siblings did no approve of the idea at all and they reported Viaa to their pack Alpha, who chased her immediately.
Viaa was injured and weak, but luckily they found Cooper and Lion who agreed to help them until their pack was stable.
As smart of a wolf as Chrono is, he has no idea how to lead a pack. He often has doubts as to whether he is a strong enough leader, and tries to act tough and confident. Really he just wants someone to guide him.
