Everyone knows the secret of Area 51, but what if there was another US government secret in the Nevada desert?
In the early 50s a traveller from the future arrived, warning that in the future time travel would become standard and if it wasn't policed it would be the greatest threat to world security they had ever seen. With his help the FBI set up the Time Agency, a group of elite agents trained to deal with threats to the timeline without the public ever being aware of their existence, based in the Nevada desert where few would notice it.
But something has gone seriously wrong.
The timeline has changed, events are taking place which shouldn't be, and as one of the few people aware something is wrong agent Jake Smithers must discover the truth before the real threat reveals itself. But is he already too late?
I would be playing Jake, your character can be anyone (as long as they're human, aside from the time travel this is a relatively realistic Earth) but you need to have something about their life that has been altered but which they are at the start of the story they are unaware isn't right. Suggestions for potential changes (although feel free to choose one of your own):
Dead family members who shouldn't be.
A wife they didn't meet in the changed timeline.
A different, perhaps less rewarding, job.
Living in the wrong town entirely.
The only other rule (aside from no power or godmodding) is that they must live in the immediate proximity of Jake as they need to be able to interact with him. Any other questions, feel free to ask.
