"This is an Earth creature called a cow," I said, smiling as I watched their reactions. "A large, hornless quadruped, bred by humans specifically for consumption. It lacks the cunning of a targ or the ferocity of a kradge, but it provides a mighty source of sustenance. For millennia, it has fed humans, grazing slowly in fields, blissfully unaware that its fate is to serve warriors at the feast. Humans used to raise vast herds of them, ensuring a constant supply of meat and milk for humanity."
