(I don't know if this belongs here. I posted it in fan fiction since it is pretty much a fanfiction thread of sorts, though given the nature maybe it belongs in lore instead?)
This is a thread for people who know their lore, and a thread for people who want to have a go at some storytelling.
Okay so here's the deal: you have to start with one single point anywhere TES history (refer to http://www.uesp.net/wiki/Lore:History), and change it. Some good examples: "No Dwemer Disappearance", "No Night of Tears", "No Tiber Septim" "No Oblivion Crisis" "The Red Year never happened" "No Stormcloak Rebellion" "No Aldmeri Dominion" etc. You only get one starting point/premiss though. From there anything is possible.
You must then explain what happens as a result of this, in a linear fashion. You must explain in detail the events that this change in TES history would cause, starting from your chosen point to the present time of 4E 200 (beyond, if you want to). Don't just tell us what the current day would be like, tell us what happens after this change and then progress to the present day. Don't fall short unless there is really nothing more of interest to tell by the time 4E 200 comes around.
Remember, the idea here is to tell a story based on a single change in TES History. Make it good.
Here is an example of an "Alternate History" if you want it.
