[Generic Fantasy] What makes iron so poisonous to Fae? I figure they're creatures of the "natural" world, and iron can be naturally found all over in ore veins and such.

Naturally occurring iron ores are generally bonded with other stuff in the form of magnetite, hematite, etc. This is different than refined irons and steels which are not naturally occurring and instead a product of civilization. So, the way I've generally understood it is it's only the processed/pure stuff which is harmful to them.
