Think about it; the food of the Fae, its origins and effects, are often strange and/or obscure.- Just like our food to most animals.
The Fae are strange beings that seem to know weird things that give them power or an edge over us.- Just like us to animals.
The Fae work and live by strange rules also often nonsensical or obscure to us.- Just like us to animals.
The Fae can easily obtain vast amounts of things we consider rare/precious/desireable, and have no problem with dishing it out wantonly for no other reason than amusement.- Just like us to animals.
