Feruchemy. Some like the word, others aren’t as happy with it. It used to be called Hemalurgy, but I decided that would be a better word for the third magic system in the series. (You’ll see it eventually.)
Feruchemy (not called that, however) was a magic system I lifted from FINAL EMPIRE PRIME, a book I wrote some years before I wrote this book. I had a person who could store up attributes, such as strength, then use them when he needed them. The thing is, the magic wasn’t really that well formed, and this character never got any viewpoints, so I didn’t get to use the magic as often as I wanted.
When I was developing this world, I knew I wanted the Keepers to have the fantastic memories. I realized that Feruchemy would make the perfect magic system for Sazed and his people. When I decided that I could use metals as a focus for this magic system (something that made it much more interesting, because it put a definable limit on what could be stored and how much of it could be stored) I knew I had something really good.
I like to use multiple magic systems in books, but I like it when they all have common elements. Feruchemy and Allomancy are like different aspects of the same concept. They both do some similar—yet different—things. There will be a lot more about this in the text.
