I thought that World Eater was just a term, and he's really just gonna kill us...
Alduin World-Eater. Don't know about you, but that sounds pretty direct. If it means anything, MK says when it comes to something like that, we should take it literally.
kinda like how Doom Drum isn't really a drum.
The name "Lorkhan" is metaphorical. http://www.gamesas.com/index.php?/topic/1173966-who-is-lorkhan/page__st__20 brings up the point why the god of space is referred to as "Doom Drum" to the mer.
Mundus isn't just Nirn either...its the entire space around Nirn. The stars are holes ripped in the veil around Mundas...so for him to eat us in one bite Alduin's mouth would have to be big enough to take the entire veil as well. The throat of the world would be smaller than his baby teeth. If that's true then we'll need some super spirit growth serum stat.
Okay, I'm guilty of using Mundus and Nirn interchangeably.
And as for death...sin't Lorkhan techniqually dead? His body is a moon and his heart is what made Red Mountain...so isnt' he basically dead? I mean, something of him remains, but I always thought of at least his body being dead once he was split in two. Or if he was brought together would be be revived? Gah! Lore is so confusing sometimes...especially now that Red Mountain blew up. The hell hapened to Lorkhan's heart now? Is he dead dead now that his heart blew up, or did his heart just get released so it can be a blot device in an upcoming game/story?
The space god is dead, but death to a god is different than a mortal or a lesser daedroth's death. To a god, death is like going to sleep, and sometimes they dream lucid dreams. Read up on Pelinal, and Wulfhart to get the idea. The space god may be dead, but he sometimes forgets, and appears as avatars, like Pelinal and Wulfhart for example. As for his heart, all we know is that the enchantments holding it have been removed, and it disappeared immediately. The heart was not destroyed, only the enchantments holding it down (jeez, do you guys even read dialog?)
But ya, killing the god of time probably isn't the best way to save our skins. Best idea would for men and mer to convice him to back off for the time being.
Problem, the mer do want the time god to destroy Mundus. They see it as a prision, and the only way to be liberated from that prison is to have the prison be destroyed.
I don't see us being able to get rid of the biginning and ending aspects of Akatosh either. I've always thought of them as one thing, only with different names for what he's currently doing. Beginning, middle, and end. Its all under time, and its just a point of view thing for what people think of him. Of course people will love him for starting time and giving them life...but they're gonna hate him for coming back and finishing his job by killing us all. Its not like he cares, he's just doing his job by beginning and ending things. Its time, just his job...and all of that makes up Akatosh. Its the mortals fault for thinking of him as three separate things...he's all of those things. He helped begin things, helped keep things going, and now he'll help end things. Nothing personal, its just how he does his job.
Well, yeah. Well, the mer see the end as a good thing. Men and, presumably, beastfolk see it as a bad thing. Also, this kalpa as apparently been going on for too long.
