Offerings to the Fae

Iarwynn is the Fae's domain. Any who enter will find that they must give an offering in exchange for their hospitality or risk angering their hosts, which is a VERY bad idea. Over the years it was discovered that the Fae have a particular liking towards dairy products. This has led to a booming economic system based entirely around dairy. Entire cities are dedicated to the raising of cattle, while the eating of beef is seen as an incredibly wasteful act, akin to igniting a $100 bill in order to light a cigarette.
