I'm reading Alloy of Law and I just thought of something. We know that Preservation tried to help Vin several times, but couldn't because of her earring, right?
But why didn't the mists reach out to Elend like they did to Vin at the end of THoA? I mean.... Vin was using Hemalurgy, so I get why the mists couldn't help her. But they could have helped Elend in THoA, right?
