Landfall the reason why every civil war debate is futile.
I have a theroy, you know how it specifically says that the only way to escape it, is to know CHIM? Thats a very specific detail dont you think? You know when you officially beat skyrim? You have the best armour, the best weapons, the best perks, etc.. Well whay do you imagine what you dovahkin does afterwards? Well what else would be better than to acheive the highest power a mortal could hold? Ya, he would focus on CHIM for the rest of his days. Meaning he has a high probability to be in the future games(that are set in the future). You know what that means? Your dovahkin will be back, being godlike and all, guns a-flamin' saving the day! That means there's still hope for salvation. Either that or a choosen of the divines or mybe another person that knows CHIM.
(Of course this is all theoretical, but has a high chance considering what sighns and clues we have at this moment.)
