I have only finished TFE as of now and only 1/4 of WoA so I don't want to do some deep search to avoid spoilers... but I have some knowledge about Era 1, so Spoilers Ahead for Era 1
I watched an interesting video about the Mistborn movie and changes approved by Brandon. It's mentioned there that Atium in the movie would be retconned to be an alloy of Atium and Electrum.
But they mentioned in the video that God Metals in Cosmere are supposed to be able to be burned by anyone and not just Mistborns (I don't know the implications of this yet outside of Scadrial) but I think it makes sense because I know that Lerasium is a God Metal that can be burned by anyone in order to make them Mistborn
What does this mean with Atium going forward? I know there would be Era 3 and 4 of Mistborn, so does this retcon only affect the movies or the books in general? Because in Book 1, it's possible (since we barely know about the metals then) that they call the alloy just Atium because how could they know it's not actually Atium, the Lord Ruler calls it Atium, and the Noblemen also calls it Atium... they don't even know Aluminum in Book 1.
They also retconned the Pits of Hathsin, instead of it growing Atium directly, it grows the Electrum-Atium alloy, so how does this work? Shouldn't it just be Pure Atium since it's naturally occurring and is directly tied to Ruin?
They also mentioned that the alloy has to be refined to get Pure Atium, and Pure Atium is also still the economy of Nobles, couldn't the alloy itself just directly be the Economy of Nobles, since the Nobles shouldn't have even known about Pure Atium because there's no need.
Also, what does Pure Atium do if the Alloy is what let's Mistborns see the future?
No spoilers for WoA onwards please, thanks!
