My first idea and the one I've got most thought out is the surfacing of a splinter cell of the enclave one that is different then the ones from Navarro and Raven Rock. I don't want to give away to may details but they allow mutants among their ranks and they are planning to spread a virus across the wastes. IT will take place in the Capital Wasteland.
The second takes place around the time of fallout 2 and tells the story of a psyker trying to fit in. I've got a basic concept down for this one but not sure exactly how the whole story will unfold.
The third is about the struggles of Desmond Lockheart as he tries to take down the rest of his pre-war enemies. This idea is very rough but I have a few ideas.
Any input will be greatly appreciated.
