Ice Silver
Ice silver, in addition to being incredibly useful, is also stunningly beautiful in its cured form, with a nice icy blue sheen on top of its already metallic appearance. It is used by many nightwalker norrith as armour plates, as well as being a fashion statement.
The material is rare but highly coveted, causing those not living in the ice caps to trade rediculous amounts of goods in exchange for even just a tiny amount. This is only exacerbated by the norrith's overcharging due to their dislike of the intrusive communities that want to do trade with them.
Ice Silver Armour sounds incredible. Love it!
