In 1986, a meltdown in reactor 4 at the Vladimir Ilyich Lenin Nuclear Power Plant in Soviet Ukraine occurred, punching a hole in reality that allowed creatures of darkness and madness to escape into our world. The tragedy that befell Pripyat, the town built to house the families of the workers at the power plant, is well known. Forced to flee, to abandon their lives, their homes, and even their loyal family dogs. Only those pets that fled to the woods survived the purge of the army, and the flames of the reclamators. You will play as these very good dogs.
When you create your dog, you'll choose a breed, which will give you edges — advantages — on certain types of actions. Your generation (wyse, wyrd, wyld) will influence your relationship with humans, and how much strange and telepathic magic you bring to the story.
During character creation, you and the other players will define your pack, and select a Pack Die to roll when taking group action. Think like a dog, and remember that how you contribute to the pack matters in your success!
