Big bad…. Harmony?
If, as has been alluded, Scadrial becomes villainous to a degree in the space age, I don’t see how that aligns with Harmony. Is Harmony just too hands off? Is galactic supremacy somehow “harmonious” in his mind? Or is there another large event between now and then that shift power dynamics of the Scadrian shard?
Maybe I’m thinking too much about this, but dominating the Cosmere doesn’t seem very harmony-filled.
