Just finished chapter 63, so no spoilers beyond that please. I don't usually share my thoughts here, but hey I Iike to read other's posts so why not do it myself and it's probably gonna be funny to read this later. A theory about ruin and atium... So we know ruin is looking for it's body and the lord ruler hid it somewhere, we also know now that it's searching for the atium which the lord ruler also hid pretty well apparently. So I think there is a relation between the two. Maybe ruin will use the atium to get her body seems like the most simple explanation. Also about the location of the atium, preservation pointed northeast when elend was returning back to fadrex, which seems to be somewhere near the mountains so that makes me think the atium is there (could explain why it pointed to his vial).
