In Mistborn, it is stated that Duralumin Feruchemy stores Connection. The exact specifics of this are unknown, but this and related things have been seen to make you understand languages as if you were a native speaker from that area. But I, in late(ish)-night unable to sleep Cosmere Theorizing, wondered if Connection shenanigans could grant you access to the Selish Arcana, such as Elantrianism or Forgery, which are location-based Investiture systems dependent on where you were born. But using Duralumin could, if this theory is correct, make you able to be taken by the Shaod. And perhaps it could also give you a breath if you used Duralumin on Nalthis. Hemalurgically this is bound to have applications too. What do you guys think?
