I love deadra shrines and hope they return. The more elaborate the better in my book. It's the combination of whackyness (you could never know what exactly you would find), treasures, weird architecture and mortal danger that was very appealing to me in morrowind.
im pretty sure jyggalag is a true daedric prince... he existed before sheogorath.
from what we learn, he apparently grew too powerful and the other princes cursed him to live in the form he hated most, madness.
this was obviously LONG ago, so jyggalag likely wasnt even acknowledged, or atleast forgotten, and any shrines he may have had were taken down... just an excuse for his absence in past games, i suppose.
also, sheogorath is gone, like i said... how can he possibly return in skyrim?
jyggalag WAS sheogorath... all we have is sheogorath's champion taking up his mantle, so the shivering isles could continue to exist.
as long as jyggalag exists, sheogorath cannot, im pretty sure, since they're two halves of the same coin.
jyggalag would need to be cursed by the other princes... AGAIN... in order for sheogorath to come back most likely... which would just be one huge kick to the balls after everything that happened in the shivering isles storyline.
i mean, dont get me wrong... i would absolutely LOVE if sheogorath was somehow brought back, but i dont think it'll happen... sheogorath was my favorite out of all the daedra, too...
anyway, back to skyrim...
i'd like to see the calendar come into play with summoning the princes, again... in arena, or was it daggerfall? i never had the chance to play the old games... couldnt you only summon the princes on certain days?
it'd atleast bring in something special about the rituals, not just delivering a handful of items and being a certain level, like in oblivion.
oh, that reminds me... i wonder if bethesda will EVER implement special events, holidays, etc... in skyrim, or future games? they were in the old games, werent they?
eh, i seem to continue slipping into discussions about past games... maybe someone else could suggest some ideas on how to handle daedric shrines, the ritualistic summonings, and daedric quests in skyrim?
For all we know, Jyggalag could have been a practical joke of sheogorath to wreck some havoc on his own world. Maybe his dementia-side thought it was good fun.
Or maybe he just suffers from split personality and will become his own sheogorath-self soon.
And it's also quite possible he told us a bunch of lies.
We're talking sheogorath here, prince of madness. You can't assume he told us the truth, or even something coherent.
