It's likely they did what Alduin did, and were transported FORWARD in time, it could be they appear in the fifth era, or even the fourth (although with dragons that would be overkill) or even the 100th era. At any random point in the future (after Skyrims events since clearly they hadn't popped up prior) they may all appear, likely many of them in the ruins of their cities, infested with creatures. Maybe the Falmer will slaughter them as revenge for what they did many era ago. (Assuming they remember)
