As the title says, can Feruchemy be taught to people other than the Terris? As I understand, it's not something that is restricted to their genetics, but I haven't read the books in a few years and some friends and I are getting ready to play the Mistborn Adventure game and we're wondering about this. I perceive the people of Terris as being their own ethnicity, but not a separate race of creature altogether. I do know that Feruchemy is a closely guarded secret, but is it possible in theory?
