The Mistborn series started way back in 2006 and felt rather complete at the time. It was unique for many reasons, but one of the things that stood out was the detailed magic system that used various metals to generate amazing powers. Allomancers are able to metabolize metals and do amazing things with them, leveraging different metals in various ways. Most people gifted in this way burn only a single metal, but very rarely someone is able to burn them all, and such a person is called Mistborn. Little did I know at the time, but author Brandon Sanderson had a plan to keep the series going in a rather unique way. He wanted to take this magic based society and move it forward through time to explore how industrial and technological advancement would mix with magic. The Alloy of Law kicks off the 2nd Era and introduces two very entertaining main characters in Wax & Wayne, taking place a full 300 years after the original. This series combines a Wild West vibe with the Allomancy of the original series, adds in even more magic systems, and then expands to explore the Cosmere in a detailed way. Does it all add up to something worth your time or does Sanderson take it all a bit too far?
