I know there is probably other posts, and I looked those also, but I couldn't find very clear answer to my question. To be more specific, I couldn't find clear answer to the problem about Sheo, Jyggalag and Daedric spheres/realms. I mean, you become Sheo, Jyggalag is freed from the curse and then what? Do you grow to be some supermortal, eventually becoming immortal? Perhaps, but maybe I just should start create huge cheese storm somewhere in Tamriel, perhaps to cover an Ayleid ruin with cheese, because they are boring?
Okay, but seriously speaking what will happen now when Jyggalag is freed from the curse? Will there be 16 daedric princes? Or will Jyggalag take your place and compeletely shut down the existence of SI? I Mean This Sheo/Jyggalag incident creates IMO a hefty problem to the 16 Deadra princes rule. So from practical point of view (i.e.for the devs) it would be easy to just destroy the SI and put Jyggalag to the position of 16th Daedra Prince- No loose ends, unknown hero, the CoC, is never heard from again and no extra Daedra Princes? But what do u guys think about this Sheo/Jyggalag problem? Will the other one cease to exist or will they co-exist?
Concerning the fate of the CoC, that's undeterminable; we can speculate all we want, but in the past few weeks, I think that's been done a lot; the same to JYG as well.
You're right about the JYG-creating-a-problem-for-Oblivion thing because this creates a problem form Creation itself as well; JYG hasn't existed since Existence started, mainly because he COULDN'T. The fact that he's back means something bad is gonna happen, as in Landfall, as in the Apocalypse.
