Hello all. You all know silver, the most useless metal. I mean, it's not even mention in most books. Except for that one little tiny, insignificant world called threnody. Threnody, however, is very unique. It's the only world with hostile cognitive shadows that can really effect the physical world. Other than roshar, of course, but whatever. Shades on threnody can only be killed with one thing... silver. So that got me thinking, what if silver possesses it's own investiture that can be used by anybody with the right knowledge? I can just hear you screaming out 'but silver doesnt affect spren on roshar!' But think about it, spren can't actually affect the physical realm, can they. Anywho, that chain of thought got me thinking something else: where did silver come from, if it's so powerful. I was thinking that it might be the body of a shard. Maybe even the body of the old threnody shard, if there was such a shard, because, It's supposedly "used up" whenever it touches a shade. This is my first theory, and it's not very good, but I hope it gets you all thinking. I appreciate any and all feedback––even negative––as long as it's posted constructively. Thanks for your time!
