Fiendish Beasts and How to Bind Them
They’re animals, sure, but not as we know it. The Lower Planes can be weird places, after all, and it shouldn’t be a surprise that the animals of these planes can be equally strange. More intelligent than your average Prime beast, but more importantly, infused with the essence of an Outer Plane, fiendish beasts can combine the ethical vacuum of animals with the most feral aspects of fiends. And let me tell you cutter, you need to learn the difference between a yeth hound and a hell hound, because one day that might just save your hide.
