So I was relistening to OG Mistborn recently and I noticed that Elend tells Vin that Atium production is down after an incident a few years ago. In context this can only mean when Kelsier escaped the pits, because the pits hadn't even been destroyed yet in the book.
My question then becomes why did Kelsier's escape from the pits reduce Atium production?
What really happened there?
And is it on any way related to the "Survive" command?
