>>14587728Silver is for evil entities. Iron is for fairies in Western Europe. However, there's no one unifying myth for fairies, or even an agreement on what kind of creatures can be called fairies. Are the youkai of Japan fairies?
On that note, I can think of far, far more tales involving the capriciousness and potential malice of fairies than I can of them working side by side with knights to fight dragons and evil. Though most are harmless, if annoying. Pokemon like Whimsicott are pretty close to this kind of fairy.
