Fetch

The rules of the Fae are complex. Fetch will get into that in the next few pages. But suffice to say, never thank a fairy no matter how nice they may have been to you. There are a few different explanations offered by folklorists, pagans, and fiction writers about why the Fae take offense at a thank you, but probably the most likely reason is it comes off condescending or dismissive. You might just deepen your debt to them.
