First encountered outside the town of Elizabeth, Night Stalkers are nocturnal creatures with the general shape of a coyote. They have heads that are longer and broader, more like a snake than a coyote. They have strips of scales down their spines and scaled, rattler tails.
Their fur is patchy otherwise.
They carry venom sacs, like poisonus snakes and can bite and inject venom into prey.
That appear to be pack hunters.
The people of Elizabeth are aware of them, but they are rarely seen.
