Warmup sketch from today colorized, still debating about Iron in the shower, my debates get rather heated with myself, I think I beat the other me up!..

I should probably see a doctor about that, but anywho.

I really can't get my head off of potential relationships between iron and copper in a hypothetical region or culture as I think they could interact well.

Iron being something that is abundant enough to where, like aluminum, you probably would just wind up with it from sundering for other metal (assuming it is affected by it, which for now it is) Meaning its a cheap copper alternative that is very uncooperative with magic. Heated in charcoal to pound it would carbonize it a little bit as a simple path to a low carbon iron.
Shit, but not any worse than copper.

Copper being somewhat abundant and easy to elementize with a broad range of applications, as well as being a useful tool material and desireable jewelry metal while also not requiring charcoal carbonization like iron... But its not quite as common.

For cultures that don't smelt their metals or melt and cast them I am at the point where I feel there is a serious argument for iron. If for nothing else its cheapness and availability. If you can circumvent iron smelting (a very difficult process) via magically splitting iron from ores via resonant sundering... It kinda just wins out and I am not sure how I feel about that.

Though copper would still be more valuable, both metals would perform comparatively and so the value for copper would be more in its capacity to take on magical properties as it always has in Õndemic reality, whereas irons value would come from being cheap and available.

still not canon but I think at this point if I don't want iron in the setting to be widespread, I would just have to say it doesn't get effected in a usable way by resonant sundering. As resonant sundering essentially nullifies the difficulties of smelting iron and just gives you a pure, but easily carbonized form of iron

bit of a disorganized ramble but yeah!
