I realize it has been around 200 years since, but don't you think that it's weird that there are NO ruins or indications of the conflict? The gates DID open everywhere (Blackmarrch, Dominion turf, cyrodiil), but yet, we find no trace of it in skyrim. When a gate was closed, it left that black structure as remains and scorched the earth. They also occasionally opened up in or very close to forts, causing damage (as seen outside bravil). Yet, we see no trace of this ANYWHERE! Not only that, but for a race of warriors and men who pride themselves in combat, you hear of no tales or exploites. You'd think that someone whould be boasting that his grandfather killed x amount of them or closed x gates. You also see no trace of a draoth (the alligator thing) spider daedra, scamp, or clanifear. I'm amazed that noone has a head of one of them mounted on a wall or a stuffed one laying around. Some still mention conflicts evn further back, but none reference a crisis that almost ended tamriel...
