here's a few simple zombie plague causers for you:
1. The Sload. Simply put, sload make a zombie plague that they made themselves immune to. Plot could be centered on attempting to discover how the magic-born disease distinguishes between sload and non-sload, then using that knowledge to create a spell that can grant immunity.
2.Re-use corpus. 'nuff said.
3. Molag Bal creates a curse, transmitted by bite, that corrupts people. The curse unleashes all their violent, lustful, sinful urges and twists their body to represent the urge in question. So, people with violent urges get turned into a form that maximizes that. Their bones become swords, their flesh hardens into armor. the greedy gain many arms to take what they want. The gluttonous become fat, with giant, teethed mouths forming on their chests and stomachs.
As to how Molag Bal spread the curse, All he needs to do is get a worshiper to enter oblivion. That worshiper becomes the first infected. They then go back to Nirn. Mortals have a pretty easy time of doing that then daedra do of the opposite.
1st or 2nd sounds like the best bet, the 3rd makes it sound like people are being turned into Demons. A remake of the Dead Horde would be fun, although with some modifications.
I think a good story story would be something along the lines of Necromancers raising armies of zombies. But zombie survival makes for really fun RP's, and a being TES-based makes every RP better. xD
I already have a character idea, one I've been working over in my head for the past couple days. Count me in, any certain template you want profiles put together with?
Name: (Nicknames and pronunciations as well if possible)
Age: (don't have to be specific, a ball park figure like 20-25 or 40-45 will suffice)
Race: (Try to be lore correct, Khajiit and Argonians are known to have sub races to let us know which.)
Gender: (obvious)
General Appearance (includes height, weight, build, and hair colour eye colour hair style facial hair, everything you can into this bit.)
Clothing/Armour: (Again be realistic.)
General skills and talents: (Describe what your guy does best and why he is trained in that art. Tell us if he also likes to paint or sing, it all counts really. Don't just say "Heavy armour, Restoration, Destruction.", try to break out of the habits of game mechanics if you can.)
Personality and temperament: (Wets himself under pressure? She giggles furiously when she's scared? Goes quiet around strangers? It all goes here.)
Brief History: Doesn't have to be pages long just give us a general idea of your character and what he/she is about. Secondary characters (who are destined to die or just aren't that important) Can be left blank and developed along the way.
Misc: Couldn't fit something any where else? Put it here
