If Mannimarco does know how to become a lich, why hasn't he become one? I know he doesn't have to worry about dying that much, but it still has the advantage of no bodily functions to weigh you down, it makes you harder to kill, which is a plus because all of those mages guild guys are NOT cool about letting him live, and I think it releases the floodgates of Aethrius. since you have no body holding you back, and thus giving you a magicka boost.
But then again, Mannimarco in Daggerfall was a bad-ass ladies man who partied a lot and had cool eyes. He'd lose those things as a lich, so it's a tough choice.
Lichdom isn't all it's cracked up to be. Ever seen Pirates of the Carribean? Sure he's powerful, but you really can't enjoy it. It's like god mod, it ruins the game. Eh, I'm not confident about the Aetherius statement, I'd think it'd be a bit harder.
No there weren't. There are no Men or Mer on Akavir, and an Akavari soldier should be an Akavari race, not a Tamrielic race.
As people have said, there were, though they were "eaten" by the Tsaeci. However, this is open to interpretation, and I have certainly read somewhere a very interesting theory on it:
First one- They were all literally eated, flesh consumed and all that good stuff.
My favorite- By "eaten", they mean absorbed, in that they interbred with the Tsaeci until the men were gone (guessing if you take your mother's race, then men bred with Tsaeci women). I believe this was used to explain some of the more human features of the Tsaeci, and I fuzzily remember something about them not being able to do something important because they didn't have any human in them. Forget what it was, sorry :shrug: And no links, I wouldn't even be able to tell you who said it.
And another one- The human ghosts were human mercenaries or slaves the Tsaeci took from Tamriel. Simple
Though if MK said it was game mechanics, I'm good with that B)
EDIT: Indeed, that is my favorite theory about him. I can certainly see his followers doing that.
