Why not? I vote yes..
In theory there are many many planes in the realm of OB, most of which are terrifying to the standard mortal. They actually differ quite a bit, and after researching lore on the dedrea gods quite a bit, I can say it may even be lore friendly that these planes would shift in appearance from time to time. So if anything, within certain.. I guess you could say, set of guidelines, a plane is really very open to variety. After all my research on the lore, I honestly think the reason most of the planes in TES 4 looked the same was just because the devs wanted to get it out on time.
Actaully thats quite wrong,
The reasons all the planes of oblivion look the same in Oblivion is because its the Dread Planes - The realm of Mehrunes Dagon.
All of mehrunes realms are the firey lava hellish realms that apprar in Oblivion. This is the realm of the dread planes - What my mod is attempting to recreate.
A good example of another plane of oblivion is the shivering isles exapnsion pack - Thats Sheogorath's (spelling??) Oblivion realm and it contrasts diffrently to the Dread Planes.
The reason for the dread planes being the most common oblivion realm in oblivion is because of the storyline of oblivion. Mehrunes was invading tamreil and therefore his gates were appearing everywhere. It wouldnt make sense to step through an oblivion gate to the dread planes and end up on azuras plane of oblivion. the gates in oblivion were meant to lead to the dread palnes. The reasons why the dread palnes look so similar is because its all ONE realm.
thought i would clear up
I wont be doing "other" planes of oblivion, just the dread planes.
The mod is taking place 6/7 years before the events of oblivion but i dont see why people/things should change. The daedra will still be the same, the realms will still be fire and brimstone and the mythic dawn should still be active. Something like the events of oblivion take years to plan.
The storyline of this mod is the mythic dawn experimenting nad try to set up a foothold in morrowind and the other proviences - preapring themselves for the dragon fires to go out. While the oblivion gates wont be as active and there wont be as many ( due to the dragon fires still being lit and the ammount of energy it takes to open a gate). The storyline focuses upon one such group that was experimenting with getting a gate open that the player then stumbles upon.
The cult cant have anyone knowing there secrets so they set about to eleminate the player.........
