[Stardust] Why is a babylon candle considered "dark magic"? All it does is transport you, no?
gpt
Candle wax was traditionally made from tallow, which is a byproduct of cow fat rendering. Or they could be made from beeswax, but that was far less common.

To make a magical candle, do you think they get the fat from a cow? No, it's a magical source. You don't want to know which one, which is why the book and movie spare us the details.
