So I just wanted to know, could ettmetal be used to store all feruchimal powers, but since there are no full-blooded terris in second era, no one has done it? And if so, couldn't someone strip away the barrier preventing others from using the power, like the lord ruler, so multiple ferrings could store their powers into the same metal and use it?
Edit: terrible wording so I'm sorry if this is confusing, but I'm really tired right now
