Wait so if Fontaine is built on a big chunk of land and has water falls then how did it flood?? Fontaine did flood to the height that we saw but if their was water falls that makes it a whole other issue, because wouldn’t that mean that in the small amount of time that was shown to use mean that all of Tyvat was flooded as well or did the Great Wall of Sumaru finally do something good?? Because if their was a whole flood It couldn’t go that high up without something keeping all that water up there but their isn’t so if Fontaine flooded doesn’t that mean that all of tyvat did for that time period?
