In the Gargoyles Universe, the fay are vulnerable to cold iron. Now, the obvious reasons for this are: a) they needed some sort of "kryptonite" to keep them from unbalancing things, and b) it's a traditional part of faerie mythology (and I'd read about that problem of theirs with cold iron long before "Gargoyles" came out, and even used it in an Arthurian fantasy novel that I'm still writing). But, did you ever develop a "within-the-story" rationale for why iron has such a drastic effect upon Oberon's Children?
