Lavenderism

When the cow goddess Amaurna created cows to provide dairy to humanity, they all provided different kinds of milk. Brown cows gave chocolate milk, yellow cows gave banana milk, and pink cows gave strawberry milk. All of the cows were considered sacred by humanity during this time, but they disliked magic and told the people not to practice magic or work with the god of the moon. Biachar did not appreciate this and his response was to call upon even more people to become magicians, but this lunar magic damaged the minds of cows as they were vulnerable to lunacy and the moon’s energy damaged their minds. The cows became violent towards the priests of the god of the moon on the command of Amaurna, so the god of the moon decided to play a prank on Amaurna. He had all the cows slaughtered except the ones who gave basic white milk, and then just painted them with his energy to trick humanity and the cow goddess. The next day, humanity was so surprised that brown cows no longer made chocolate milk, that a lot of them were no longer able to digest milk, and lactose intolerance was born.
