It was true. There were other wolves out there. Different ones from herself and Caeto. Evil, dark and blood hungry wolves. They prey on fear, hiding in the shadows. If those monsters are around, surely the darkness is winning and the light is losing. They'll stop at nothing for power. No. I will not let those beasts achieve their power.

Wolves were killing. It was a different world. And her paws just travelled her through it all. And how would this all stop? Perhaps hope is still here.
