Are you guys talking bosmer, dunmer, and altmer, or about other elves?

They probably all can, with magic. Even master human sorcerers outlive their peers. But I don't think that elves normally live that long.

Shivering Isles didnt make sence. Oblivion made little sence. I cant wait to see how Beth will explain it all in the next game.

Do you really think they will explain it?

I prefer the "it's just a big illusion LOL" theory myself.

Not like he hopes. I'd bet there will be rumors and comments in the dialogue that pick at the Oblivion Crisis, but an explanation is highly doubtful. The ending to Oblivons MQ is just like any other ending to TES. It requires paying attention to detail, and then you, the player, try to make an educated guess as to what you think happened. IMHO.

Even though I would welcome a thorough explanation.

Prince of Madness

The Mad God actually. But I guess you could call him the Mad Prince as well and vice verca.

Aging, becoming more and more frail and vulnerable until your body finally ceases working altogether, is a limitation. This is Lorkhan's stuff. It doesn't exist outside of Nirn, where other principles are instead embodied to the extreme.

at the end of the SI main quest you can talk to Dyus and he says something about how your the only one that can release him from his immortality so my question is can you release Dyus from his imprisonment or does he have a larger part to play in future elder scrolls games?

Don't know. Could be. Maybe not.

We see Sheogorath aged, because that is how we percieve him as the era of madness closes into sterile order. He (the realm) is represented in sterile, simetrical order too. The world is split into two aspects, instead of him being the extreme of one or the other. These phases are close to the effects of time, and that is what we see.

In other words, the Greymarch created a begining and end to mark time from, without it there won't be an "aging" Sheogorath.

I'd imagine they're immortal. That other guy I can't remember the name who was in Sheogorath's old library survived all of the Greymarches.

It's Madness to people who aren't considered "Mad". But from the perspective of one who lives in the Shivering Isles, the strange adventurer that doesn't mumble to himself would seem a bit strange, no?

The woman that claimed she lived through the Greymarch said she hid from the destruction. My guess would be through magical ways. But I'm just trying to put a reason to the Developers' laziness on the lore side.

I think Sheogorath spared him after Sheogorath destroyed the library. Before Jyggalag became Sheogorath, Jyggalag had a great library with tons of knowleged but it was in perfect order. So when Jyggalag became Sheogorath, Sheogorath discoverd this library and had it burned down, but Sheogorath didn't want to lose the knowleged so he spared Dyus(which was the guy in charge of the library)to save the knowlege but since Dyus was order Jyggalag wouldn't hurt him.

Incorrect. Sheogorath benefits from the ease of existence afforded by the Time God, thus time exists there as well, just like every other Et'Ada.

On that note... what were the Daedric Realms doing during the great dragon break in the first era?

A Dragon Break doesn't mean that time stops or that Akatosh is actually broken. It means that some new gods that don't know what they are doing start to control the sequence of events on Mundus, much like the et'Ada did in the Aurbis before Akatosh (ref: Nu-Mantia Intercept).

It got that name because the Marakuthi Selective tried to break Akatosh, couldn't and then tried something else. Presumably becoming gods themselves so that they could replace the "Merish" pantheon with completely human gods.
