Yes, but you think someone'd notice. Also, the Neveraine should still be walking around, along with the guy who saved Tamriel from Jagar Tharn. My my my, what a lore head-ache :facepalm:
Rumor has it that the Nerevarinev has left Morrowind on an expedition to Akavir and has not been heard from since, that's likely Bethesda's way of writing him out so that what the Nerevarine is doing doesn't need to be addressed. As for the Arena guy, who knows? If he yet lives, though, he would probably have retired from adventuring after 40 years.
not really i mean the average life span of a human in a time period with the level of tech as in this time in Nirn would probably not live longer then 40 years and that would be pretty old factor in a life time of adventure and battle well you get the picture
That is, assuming that the average lifespan of a human in the Elder Scrolls world is the same as what it would be in an era of comparable technological advancement, which is flawed as Tamriel doesn't take place on Earth, instead, it takes place in a world where magic is common place, and where, if gameplay is any indication, most diseases can be cured fairly easily and wounds quickly healed with spells and potions, so maybe humans live longer in that world than they did in the real world time period it resembles. You also seem to forget the fact that not everyone in Tamriel is human, Dunmer and Altmer, and possibly Bosmer as well, can live much longer than real humans, and many you meet in the game were certainly around during the time of Arena.
People of Tamriel are a stoic lot. Not much excites them, it will take a Landfall really to shuffle their feathers.
You'd actually expect that to be the case, given how often sinister plots that threaten the peace of Tamriel seem to happen, though given that people in Oblivion seen to consider mudcrabs a pretty important thing to discuss, one would almost be led to think that there weren't any events that could bring about the end of the world as we know it going on at all.
