Cows are actually from the land of the demons. The first cows were demons that went so demented that they couldn't maintain a physical form and collapsed into nothing. When their mind became stable enough to come back into existence they became all sorts of monstrosities. One, the dermontanianain shlouder, also known as the demotic cow,escaped through a portal and was domesticated. It became the cow. Sometimes the demon in the cow surfaces and they turn into minotaurs and other cow fiends.
