I am new to the Cosmere and fantasy genre in general and finished reading the original Mistborn trilogy and the part where they die seems very sad to me. I have read through Harry Potter, Inheritance Cycle, and Percy Jackson series and none of the endings hit me like a sack of bricks like this one did. In my opinion, at least one of them should have lived. I was expecting Elend to die since the second book but never thought the protagonist herself would die too. The only happy aspect of that ending was Sazed says they are happy wherever they are but we don't actually get to see this conversation which is a bummer. Are all of Brandon's books like this where the main character has no plot armor?
