True Iron

True iron is what the fae creatures refer to any iron based alloy found in Sigg. A fae that comes into contact with True Iron is inflicted with intense burning sensations and their skin reacts violently with cracked rashes and oozing blisters. If contact remains too long, the fae receives blood-iron poisoning and dies shortly after. More purely concentrated iron can have even more drastic effects, some causing fae creatures to burst into flame at its touch. Having such true iron, even in small quantities can be a strong deterrent if presently confidently to an aggressing fae creature.
