Uh…they grow in a land ruled over and controlled by a megalomaniac undead dragon, who wants to suck all the life from the world, cared for by undead farmers who desire nothing better than to tear your face off and use it for a handkerchief, fertilized by 300 year old cattle and the blood of victims too foolish to leave the place alone.
I’d say they taste like rainbows…yep definitely rainbows.
